Space limitation always becomes an issue when you are an avid gardener. You need a veg space and a flowering room. What about clones and seedlings? What happens if some plants are sick or have bugs? Do you have a place to quarantine them? Perhaps you also want to grow mushrooms. Where can they go? Mine are in my daughter’s bedroom while she is off to college! You get the picture. The more you get into it, the more you want to grow. As a Canadian, the idea that I can grow anything in my grow room is fascinating. I can’t imagine life without a garden. This subject is at the core of what Garden Culture is all about. Our mission is to help you be better growers and to help teach people how to use their unique space as effectively and efficiently as possible. This edition has some great articles, from tissue culture (part 3) and picking an air conditioner for small spaces to lighting, biodynamics, ferments, and so much more. We hope you love this edition as much as we do. Please visit us at GCMAG.co where all articles from the past ten years are there for you to search.

There isn’t anything about gardening I don’t enjoy. There’s always something new happening and things to learn

Author Spotlight

Jennifer Cole

ennifer Cole is one of Garden Culture’s newest writers, and we are so happy to add her voice to our pages! Hailing from beautiful Vancouver, British Columbia,

Jennifer is a passionate gardener who loves to share tips and tricks from her growing experiences in her urban oasis. You can find many entertaining and informative reads by Jennifer on our blog (GCMag.co), and in this edition, we hope you enjoy her look at food forests from around the world. So let’s get to know her a bit better, shall we?

What is your favourite plant to grow?

What is your favourite animal/insect?

The list keeps growing (excuse the pun)! My absolute favourite vegetable to grow in my small urban garden is kale. It tolerates part shade, which my garden has a lot of, and is a staple for salads and smoothies, yielding a good harvest for a long time. As for ornamental plants, I love hydrangea. They’re generally reliable, coming back year after year, and add colour to the landscape for a long time in the summer. That makes them a star in my mind.

My garden has a lot of hummingbirds and bees. I love seeing them at work, going from one plant to the next, knowing that they are helping the garden’s small ecosystem and further aiding in overall plant health.

Do you grow organic? Yes, absolutely. Working with nature as much as possible to grow anything is better for the plant and the planet.

What’s your favourite activity to do outside of work? There isn’t anything about gardening I don’t enjoy. There’s always something new happening and things to learn. It’s how I relax and unplug. I never take my phone out to the garden, so I’m not bothered by texts or calls and can spend hours lost and nurturing the space. Anytime there’s an opportunity to connect to nature is valuable and awe-inspiring, even in my small garden space. 3

What is your favourite food? I have a gluten-free diet, so it often boils down to salads and vegetables. Asparagus is coming into season, and that’s a definite favourite. Strawberries top the list too, but a gluten-free penne with homemade marinara sauce and parmesan cheese is the epitome of comfort food.

5Tips For Your Best Indoor Grow Yet

Rich Hamilton offers his list of top five ways to maximise yields in the indoor garden.

INDOOR GROWING

Use Mycorrhiza Mycorrhiza is a versatile organic additive that you can incorporate into any substrate and growing style. Mycorrhiza is a fungal system that exists in the ground and on most plant roots. There are two different types of mycorrhizae; endo and ecto. Endo mycorrhizae live on and inside plant roots, and ecto grows on and around the origins of the plants.

Learn to read your plants; they will tell you everything you need to know!

The host plant and mycorrhiza have a symbiotic relationship. The mycorrhiza spreads out its microscopic filaments called hyphae through the medium and acts like a giant sponge, absorbing more nutrients for the plant than the root system could manage alone. In return for nitrogen, the mycorrhiza increases the roots’ total nutrient uptake by a thousandfold! Mycorrhiza is a cheap and natural way to boost yields. You can buy mycorrhiza in powder and liquid form. I have found that the powder form sprinkled directly onto the roots while repotting works best.

Prevention is Better Than Cure When growing indoors, it is almost certain that you will have to deal with pests, and they can devastate a yield very quickly. Confined, warm climates with no natural predators make it a perfect setting for pests to feast and breed. Prevent unwanted bugs using barriers on all air intakes. These fine mesh coverings will minimise airborne problems from being sucked into your grow room from outside. New plants and cuttings can also transfer pests into the grow room environment. When introducing new plants, ensure they are treated and checked. Problems can go undetected if hidden in the soil or substrate, so quarantine new plants for two weeks to ensure they are clean. Another good idea is to have gardening clothes exclusively worn in the grow room. Wearing clothing that has been outside can help pests piggyback their way indoors.

The best LED grow lights can be more expensive than traditional lighting systems, but they will save money in the long run. These full-spectrum lights have everything you need for the entire lifecycle. You can even install a system specifically tailored to the type of crop you grow.

Don’t Disturb the Light Cycle Plants respond more to light changes during flowering, so any light cycle interruption during that stage impacts growth and yield. If the lights are on for too long, the plants could go back into veg. If the lights are off for a day or two, you may see the flowers grow faster; this is not necessarily a good thing because they will lack nutrition. Sudden changes in light will also affect the temperature in the environment and could put your plants into thermal shock, causing further stress and difficulties. To avoid these issues check for ‘’light leaks’’ in the grow room. Light can seep in through open vents, unravelled seams, broken zips or tears in the main fabric. To prevent light/darkness interruptions, a dual grow light timer is essential. This gadget lets you accurately adjust the lighting times automatically. To keep things simple, invest in a quality environment controller that will run all the lights and monitor the humidity and temperature control.

Observation Learn to read your plants; they will tell you everything you need to know! An overly leggy bean or a yellowed tomato plant will tell you plenty about your gardening methods. Ask questions about the type of care the plant needs. What do you know about it, and under what conditions will it thrive? Use gardening failures as an opportunity to re-evaluate and improve your practices. Keep a diary to take notes throughout the plant’s lifecycle, and you’ll be a better grower with every new season. 3

Use LED Grow Lights You will need to invest in some LED grow lights when growing indoors. LED lamps have a longer lifespan than the average light bulb. With lower operating temperatures, LED grow light systems aren’t very harsh on plants and can run for as long as 50,000 hours. These systems make controlling constant humidity and temperature easier, reducing water consumption by up to 80%. In addition, LED lights use significantly less power than other options and help lower energy bills.

edibles. Many people have to juggle the functionality of outdoor spaces. It can be tricky to balance outdoor seating, lawn for pets and children to play, privacy screens from neighbours and structural elements like the clothesline and bins. So how do you squeeze food into already tight areas?

Many of my clients have small properties and experience these limitations but are still keen to grow food, especially in uncertain times. Food security has become a higher priority for many homeowners and beginner gardeners. However, in urban suburbs and densely populated estates, most properties have narrow access down the sides of the home. These areas often lack privacy and are underutilised or overshadowed by neighbouring buildings. Limited sunlight and wind tunnels are common issues. Boundary fences are usually very close to the house eaves with very little room for planting. Understandably, many homeowners choose low maintenance ornamental plants for landscaping. However, some ornamental shrubs and trees can take up valuable space without providing tangible benefits regarding food, privacy or habitat. So how can we overcome these common challenges and find room for edibles?

Small Space Design Good design and careful plant choices can open up opportunities for many gardeners. Let’s take a look at some examples. Amy and Lachlan are a busy young couple with two dogs and a new baby. Their backyard consists of a tiny lawn, paved outdoor entertaining area and hedging plants to provide privacy between their very close neighbours. Their goal is to grow at least some fruit, vegetables and herbs. However, the only way they could make room for some edible species was to be tough ‘landlords.’ Some of their ornamental plant ‘tenants’ were taking up valuable real estate. The attractive hedge species did provide privacy, but they needed regular pruning. They were in a prime position for sunlight during winter and morning sun/afternoon shade in summer. This ideal food garden position was wasted by ‘leasing’ out this zone to existing non-edibles. They removed three large trees with thoughtful redesign and had room to use the space wisely while not sacrificing their privacy—a highly productive decision.

Screening trees were replaced with decorative privacy panels, fruiting crops and a raised bed

GA R D EN CU LT U R E M AGA Z I N E.CO M

Careful plant choices with space-saving varieties and thoughtful positioning allow the entire garden bed to be fully utilised without compromising a harvest Perennial crops and passionfruit climbers maximise use of narrow space

Instead of a living hedge screen, decorative panels were added to the fence, keeping the neighbours happy. With the trees gone, there was room in the corner for a dwarf lemon tree (the fruit they buy and use most often). This new compact VIP plant tenant will provide a return on investment for years to come, as citrus trees fruit year-round in our subtropical climate. With thick mulch at the base, the lemon tree doesn’t compete with the lawn for nutrients.

Growing Up The next element in their design was to choose a narrow raised garden bed positioned snugly beside the fence. This is suitable for a variety of perennial and annual vegetables. Steel wires were attached to posts to fully utilise the fence space behind the raised bed, ideal for edible climbers. Since passionfruit have a long life and growing season, one was planted on either side of the raised bed. The vines are being trained upwards to take advantage of vertical growing space. The fruit will be easy to harvest, and the vines will soften the fence as a living green wall. They are also thinking of extending the vertical growing system along the next section of the fence to expand the available vertical growing space.

Reusing ‘Waste’ The raised garden bed is quite deep. So, it would have been costly and pointless to fill the entire depth with soil. By utilising the Hugelkultur technique – a way of layering organic ‘waste’ from natural materials, Amy and Lachlan could save the time and effort of removing the trees off-site. The trunks, branches and dead leaves that were cut down from the trees were laid in the bottom of the raised bed and layered with lawn clippings up to about 30cm (12”). Over time, this organic matter will decompose and create healthy, moisture-holding soil with native worms, mycorrhizal fungi and beneficial microbes. This technique adds value by reusing natural materials onsite, sequestering carbon into the soil. The rest of the bed was layered and filled with compost, aged cow manure, rehydrated coir peat, rock minerals and slowrelease organic pelletised nutrients. After topping with mulch, they planted new perennial plants like compact mini Lebanese eggplant, banana capsicum and ginger, along with strawberries, celery, spinach and spring onions. Careful plant choices with space-saving varieties and thoughtful positioning allow the entire garden bed to be fully utilised without compromising a harvest. In just a few weeks, the plants are already producing fruiting crops, and the passionfruit have taken advantage of the sunlight to start climbing the wires.

This raised bed is used for leafy greens and herbs; quick picks close to the kitchen. Another narrow planter sits up tight against the wall under the eaves.

They have similar water and full sun needs, so they are perfect pot partners.

Free Fertilisers The Vegepod water reservoir pumps out nutrient-rich liquid fertiliser captured in buckets and watering cans and reused on the other edibles. No wasted nutrients! Likewise, a mini insitu compost bin has been installed in the raised bed. Kitchen scraps and green garden waste is added to the bin. Holes have been drilled below the lid, down the sides and in the base to encourage worms and beneficial microbes to enter and decompose the food rather than it ending up in a landfill. Worms fertilise the plants with their nutrient-rich vermicast manure, reducing the need to fertilise. By adding rock minerals to the mini compost bin, the worms also redistribute these in a bioavailable form for the plants to take up quickly. The holes below the lid are left open above the mulch so black soldier flies can enter to lay their eggs. Their larvae are fast decomposers and recycle the food scraps into a liquid fertiliser that leaches out the base. This system is ideal for busy gardeners. No heavy turning of compost systems is required. Instead, they employ nature’s free ‘workers’ to do the hard composting work for them, a win-win solution for putting more food on the table sooner. 3

Lighting a small

indoor

garden If the grow room is small or has an irregular shape, the importance of selecting the correct kind of grow lights increases

SMALL SPACE LIGHTING

hoosing the right light for an indoor growing environment is crucial. It’s a decision that can be the difference between a poor yield with complications and an easy, problem-free grow with bumper returns. If the grow room is small or has an irregular shape, the importance of selecting the correct kind of grow lights increases.

The bottom line is that you get what you pay for The three different types of grow lights available on the market today are as follows: • • •

CFL (Compact Fluorescent Lamp) HID (High-Intensity discharge) LED (Light Emitting Diode)

CFL CFL grow lights are the most economical option, reliable for raising seeds, cuttings, and vegetative growth. In addition, CFLs produce little heat, don’t consume much power, and don’t require a ballast, making them suitable for small gardens or tight budgets.

2. CFL Units: These are mainly used in the propagation part of a plant’s cycle. You can use CFLs throughout your plant’s entire life by alternating between the blue and red spectrum. However, remember that using CFLs throughout flowering will result in lower yields. 3. CFL Bulbs: These look like giant energy-saving lightbulbs. They come in different light spectrums and can be hung vertically or horizontally, making them great for tight or awkward spaces. CFL bulbs run cool on very low wattages. Great for small areas where excess heat may be an issue. CFL bulbs are notoriously fragile, so be careful.

HID Grow Lights

Although you can use CFLs throughout flower, the lack of heat means that yields will be poorer than if an alternative light source is used. In colder climates, you may need a heater to compensate for the cool running of the CFLs; this may be an issue if you are already struggling for space in a small growing environment.

HID is a long-time favourite of indoor growers at both the hobby and commercial levels. HID comprises a double or single-ended lamp, a reflector and a ballast/driver. Various configurations are available. Sometimes, the ballast is separate from the reflector and the light, and other times it is one fixed unit.

CFL lighting units come in three main configurations:

HID lights are extremely powerful, give off a lot of heat (at both the bulb and the driver/ballast), and consume a lot of electricity. Depending on what type you are using, they may also require unique fixtures and ballasts. If using digital ballasts, check if they emit radio frequency interference or RFI.

1. CFL Strips: This single strip light is sometimes housed within a frame that holds multiple CFL strips. This light fixture generally comes in lengths of two to four feet and is sold in doubles, four-bar configurations, and singles. They are powered from end to end and are hung lengthways.

LED (Light Emitting Diode)

Choosing the right light for an indoor growing environment is crucial HID (High-Intensity discharge)

However, it is recommended to move to the HPS for flower for best results.

Small Gro w Room tips, Tricks and Failures 30

SMALL GROW ROOM TIPS

alking about small grow rooms is uniquely fun for me as I just spent the last 12 months putting my new mini 20’ x 8’ shipping container through

its paces. We did some incredible stuff but also made our share of mistakes. With my background in HVAC and automation, we did our best to design our system to understand everything happening in the space and data log the information to determine how to make the system better. Along the way, we realised that some choices were better than others.

When bottom watering, the top layer of the soil always stays dry, and in turn, you tend never to see any bugs, even if you know they are there

Flooring Linoleum tiles were not the right choice. We put glue-on tiles on top of the insulated subfloor we had created. Laying 2” x4” on the wide side allowed us to get 1.5” ridged insulation in the floor and then secure our plywood to the top. We then glued the tiles on top. The tiles are challenging to clean and very difficult not to want to slide/move with all the humidity in the grow room. Next time, sheet linoleum or epoxy floors would be critical.

Bottom Watering Bottom watering is something my clients have been talking to me about for a long time and something I hadn’t quite caught on to until growing myself. I found it even more helpful when running soil, as it helps stop Thrip and Fungus Gnat problems. When bottom watering, the top layer of the soil always stays dry, and in turn, you tend never to see any bugs, even if you know they are there. We had great success controlling our rooms with this technique. The other great thing about bottom watering and irrigation mats is their benefit to your environment humidity control. With the mat (and rolling bottom water trays for moms), we have never needed to add a humidifier to the space. Instead, the mat acts as a constant humidify supply when water is required in the air. Using this technique in a small room led to very stable temperature and humidity conditions.

Room Conditions Small spaces make for stable environments; however, they can also make for a roller coaster of bad conditions if you try to make too many changes too quickly. I know people have different personal preferences on room conditions, and depending on your style of growing and your genetics, you can maintain different conditions and still be a successful grower. However, in a small grow, climate changes fast! I always try to keep my temperature and RH stable and don’t change the control much at one time, or the room will quickly over cool or overheat. My grow room is generally at 82°F and 60%RH all day and night. We made that decision to control problems more than to make the best grow conditions at every second for the plant. With most growers having pests and Powdery Mildew (PM) issues, a stable environment

can help both. PM doesn’t like to spread at that specific condition, and if you like predator bugs, they tend to thrive. These small grow systems often don’t have sophisticated controls and automation, so that stability may not give the best yield, but it will protect your plants. Generally, I lower the temp the last couple of weeks. However, it is still stable, and I’m not worried about problems occurring by then.

Where Plant Problems Come From If you can start from seed and pheno hunt yourself, it can be a lot of fun and prevent problems from happening in your grow. We never had any issues until another grower came to visit. Since then, we have been extremely picky about clean clothes, hair, external plants, etc. The best way to prevent external threats is to keep your grow under a tight lockdown: the fewer people that enter, the less risk of problems. Growing in a small space is a lot of fun and provides unlimited enjoyment and a lot of potential frustration. Keep your space clean, love your plants, and good things will happen. 3

Like an ornamental garden, foodscaping must be well-planned 34

FOODSCAPING

ith manicured lawns and perfectly trimmed shrubs, the landscaping surrounding North American homes and buildings was, until recently, mostly considered decorative. However, a new way of designing gardens, particularly appreciated by millennials, has just made its appearance: foodscaping!

A Functional, Ecological and Productive Garden The principle of foodscaping is simple because it involves designing gardens in which edible plants are grown. By making your own edible landscaping, you will be able to create a functional and ecological living environment that will allow you to produce organic, fresh, tasty and inexpensive food!

By making your own edible landscaping, you will be able to create a functional and ecological living environment that will allow you to produce organic, fresh, tast y and inexpensive food!

Numerous edible plants, such as Swiss chard (Beta vulgaris var. cicla), strawberries (Fragaria x ananassa), kale (Brassica oleracea var. acephala), scarlet runner beans (Phaseolus coccineus) and peppers (Capsicum annuum), for example, are just as decorative as most annual and perennial flowers. Furthermore, to make your foodscaping as aesthetic and colourful as possible, you can associate edible flowers, such as carnations (Dianthus) and pansies (Viola x witrockiana), with most vegetables.

Nut trees, fruit trees and shrubs, perennial or tropical vegetables, herbs, edible flowers and medicinal plants; any of these has its place in edible landscaping. They have the ability to produce vegetables and fruits in abundance, year after year, with little maintenance. As it is the case for permaculture, edible landscaping is also a sustainable ecosystem that respects living creatures in which interventions are minimal.

If you have a mature garden, an easy way to incorporate edible plants is to introduce those with ornamental qualities into your flower beds. Gradually, you will be able to transform some of your non-productive borders into edible and utilitarian landscaping.

A Landscaping Just As Good As Beautiful

An Edible Garden With Style

Vegetables are considered by a majority of people to be quite unattractive, so they are often grown in a corner of the land far from the house. On the other hand, since it consists of plants that are just as beautiful as they are edible, foodscaping can be achieved almost anywhere: on the front land of a residence, on a terrace or even on a roof!

What materials should be used for the creation of foodscaping? Apart from the fact that it is better to choose materials that are in harmony with those of the house, there is no established rule. Some will prefer modern materials such as cut stone and stainless steel, while others will want old farmhouse materials such as rusty steel, barn wood and straw bales. The recovery of used materials for the creation of edible landscaping is particularly popular among millennials.

Called the Fruit of longevity by the Japanese, the honeyberry (Lonicera caerulea var. edulis) produces elongated berries very rich in antioxidants

A Well-Structured Foodscaping If you want to be successful at creating edible landscaping at home, make sure that you plant fruit trees. In addition to maximising the use of space, these plants form the backbone of a garden since they are, in a way, pivots around which the lower edible plants are then placed.

If you have a mature garden, an easy way to incorporate edible plants is to introduce those with ornamental qualities into your flower beds

You can opt for an apple tree or a cherry tree, but these species should be reserved for experienced gardeners. I suggest you plant hardy small fruit trees which produce little shade and require little maintenance, such as serviceberry (Amelanchier alnifolia), sea buckthorn (Hippophae rhamnoides) or Asian pear (Pyrus pyrifolia).

If you live in an urban environment and your land is particularly small, plant hardy kiwi (Actinidia kolomikta), a climbing fruit species with beautiful variegated foliage producing an abundance of edible sweet berries very rich in vitamin C!

It is possible to associate edible plants the same way one creates an ornamental border, according to their height, shape, texture and colour.

To facilitate the maintenance of edible landscaping, it is advisable to plant herbs and perennial vegetables. Among the most easy to grow perennial edibles are the Egyptian onion (Allium cepa var. proliferum), a perennial plant that is a good substitute for the common onion; skirret (Sium sisarum), which has a sweet and long white root that looks like parsnip; sea kale (Crambe maritima), whose fleshy leaves have a concentrated taste of cabbage, and Jerusalem artichoke (Helianthus tuberosum), whose artichoke-flavoured root is very rich in fructans - considered as prebiotics that participate in the balance of the intestinal flora – and is a wonderful substitute for potato. However, this plant is particularly aggressive, so it is necessary to install it in a large pot buried in the ground or to surround it with a thick metal border.

Many species of fruit shrubs can be easily incorporated into edible landscaping. Highbush blueberries (Vaccinium corymbosum) and raspberries (Rubus idaeus) are certainly the most popular. In addition, many recently introduced cultivars, including Raspberry Shortcake™ (Rubus idaeus Raspberry Shortcake™), are small in size and are well adapted to be grown in containers in urban gardens. Some native fruit shrubs such as black chokeberry (Aronia melanocarpa), honeyberry (Lonicera caerulea var. edulis) and black elderberry (Sambucus canadensis) are very popular among younger generations of gardeners.

A Perennial Edible Garden The herbaceous edible plants (perennial and annual vegetables, herbs, edible flowers and medicinal plants) can be arranged creatively at the base of shrubs and trees.

To Fight

Change!

PLANTING TREES

very day brings its share of negative environmental news; it is easy to feel completely overwhelmed and helpless as the planet battles the effects of global warming. However, by organising or participating in a tree planting event in your community, you will feel that you are making a difference in this crucial fight. Join the

movement, and you will see that planting a tree brings a smile!

The Best Carbon Capture Solution

Planting Trees A Powerful Action

In a 2019 study published in Science magazine, Swiss researchers estimated that we needed to plant around one trillion (one thousand billion) trees to counter the effects of climate change effectively. They calculated that the newly planted trees could absorb nearly 750 billion metric tons of carbon dioxide. That’s about as much CO2 as humans have released over the past 25 years. However, according to several exper ts, planting trees cannot replace reducing or stopping our use of fossil fuels such as oil and coal, the main culprits of global warming. Other means of fighting climate change exist, such as vegetarianism and the use of electricity from renewable sources. But planting trees remains the most affordable and effective solution.

Changing The World, One Tree At A Time Deforestation is a significant issue on our planet. Each year, between 13 and 15 million hectares of forest disappear, an area equivalent to the size of Belgium.

I strongly encourage you to plant a tree or two on your proper ty this spring. Doing so is a powerful step in fighting climate change and signifies your love and respect for nature.

Follow these guidelines when planting your trees:

1. Your purchased tree should be transpor ted in a vehicle with an air tight body to protect it from drying out.

Dig a hole with a diameter exceeding the root ball by about 30 cm. The depth should be 30 cm more than the root ball’s height. Half of the hole should consist of the loosened existing soil. Fill the rest with rich planting soil.

The United Nations Environment Programme has launched the Plant for the Planet, an initiative that aims to plant at least one trillion trees worldwide. Since 2006, more than 14 billion trees have been planted and registered on its website. You can contribute to reforestation and reduce the impact of global warming by planting trees and registering them online at trilliontreecampaign.org. Planting a tree is a concrete action, especially when it is done with your kids.

PLANTING TREES

By organising or participating in a tree planting event in your community, you will feel that you are making a difference in this crucial fight

Remove the plastic pot that covers the tree’s root system. Clean the container and return it to your nursery or put it in the recycling bin.

4. Place the tree in the hole so that its collar – the par t where the roots meet the trunk – is level with the ground’s surface. levelling

6. Stabilise the tree with a metal stake to protect it from the wind. Attach the tree with a sling fixed to the end of the stake so that it is two-thirds of the total height of the tree trunk. Plant the stake with a fence post driver, a tool made of a hollow cylinder equipped with two handles to avoid injury.

Add planting soil around the root ball in successive layers (15cm thick each), compacting it lightly with your hands. The planting mix should consist of two par ts of existing soil mixed with one par t compost. Adding some mycorrhizal fungi will also help with the tree’s growth.

Finally, create an ear then basin around the tree to help with water retention for the next couple of years. This basin should have a diameter equivalent to the planting hole with edges approximately 10 cm high. Water once a week throughout the summer. 3

am a gardener, and I can help improve these conditions.

Sustainable gardening is the way; that is, wisely using water, reducing fossil fuels to run our machines, and conserving our soil. Gardens today need to be resilient and produce in adverse climate conditions such as extreme temperatures, strong winds, heavy rains, and flooding. Restorative gardens improve the soil structure and fertility and prevent water from washing away the earth. In addition, healthy soils can mitigate the stresses of high temperatures. The result is livable landscapes for us and our native birds, bees, spiders, and other animals. So what are you waiting for? Follow these five tips to make your best, most climate-friendly garden yet!

Quick Tips • Compost kitchen and yard waste. • Cover beds/soil with plants and compost. Use cover crops on vegetable gardens once harvested. Before planting, cut/ mow down and incorporate into the soil. • Leave short grass clippings on the lawn. • Use plants with long fibrous roots (native plants) in beds.

Build Healthy Soil Living soil will support healthy plants that do not need fertilisers or extra water. It provides homes for microorganisms that break down organic matter, making nutrients available to plants. With ultimate conditions, new plants will acclimate quickly and produce vigorous root structures. As a result, a habitat begins to form where native plants and animals thrive. According to Charlotte Blome, the manager of horticultural programmes at the Shedd Aquarium in Chicago, a tablespoon of soil holds eight billion microorganisms critical to building healthy soils. How can gardeners build healthy soil? First, you must consider where you live and how the site has been previously used. My plot in the U.S. upper Midwest was row-cropped and had animals on it before the former owners built a house and seeded a lawn. The clay soil was compacted by machinery, and its nutrients were not readily available to plants. So we began to compost and added plants to the landscape. We removed and composted sod for our large vegetable garden, and over time, did the same for our beds of perennials, shrubs, and trees. These actions yielded results; our vegetable garden is amazingly diggable, and the perennials are easily lifted and divided. We leave a large portion of plant debris in the garden, and we do not need additional fertilising. Blome says to “leave the soil alone” and advises, “go easy on it in the fall.”

AVERTING CLIMATE CHANGE

Collect Rainwater After many years of designing landscapes, I am more confident than ever of the power of water. On each new site, I look first to where the water is going and how it can be better managed. We need to protect our homes from running water. As rain events become more severe with climate change, how can our properties become more resilient? According to the Iowa Stormwater Education Partnership, green infrastructure is designed to capture, infiltrate, cleanse, and detain rainfall close to where it hits the landscape. Appropriate methods are implemented in a treatment train where water will be cleaner and safer before leaving a site. A sustainable approach to natural landscape preservation, conservation of water resources, and stormwater management allows more stormwater to infiltrate the ground and recharge groundwater supplies.

Quick Tips •Direct downspouts to areas away from foundations. Avoid having only one or two to handle all the roof runoff. Send water to storm sewers only when you have exhausted ways to manage stormwater on-site. •Use green infrastructure such as rain gardens and swales to keep water on site. Water directed to a rain garden will gradually percolate into the ground. Swales will do this as well, but when used on a slope, will move water downhill. •Save water to use on gardens with cisterns and rain barrels. •Prevent erosion with healthy soils and vegetation.

As rain events become more severe with climate change, how can our properties become more resilient?

Store Carbon Cool the atmosphere by sequestering carbon in the soil. Plants take carbon out of the air and store it in the ground through their roots. Humus, formed by fungi, is the most stable form of carbon in the soil. Carbon dioxide and other gases cause the greenhouse effect. As the sun warms the earth, heat radiates back into the atmosphere, allowing some to escape into space. The increased emission of gases prevents excessive heat from leaving. As a result, our climate has warmed. My explanation leaves out many details. I have found excellent sources to help me understand and act. One book is The Thinking Person’s Guide to Climate Change, 2nd Edition by Robert Henson. Plants take CO2 and use it in photosynthesis to convert energy from the sun into carbohydrates for growth. Carbon is sequestered in soil by plants through photosynthesis. Adding plants to our landscapes is a way to capture and store carbon. When we moved to our property, it was too hot to play outside, and gardening was difficult. So we began planting, and now, at every time of day, a large portion of the space is shaded. The beds do not need water, and the grass grows better. Our plants are not stressed, and we have a welcoming habitat.

Quick Tips • Plant trees, shrubs, and perennials. Cover your property with as many planted areas as possible. • Use windbreak trees and shrubs to lessen the effect of hot winds in the summer and cold winds in the winter. • Shady areas lead to less evaporation of rainwater into the atmosphere.

AVERTING CLIMATE CHANGE

Reduce Fossil Fuel Use we can make effective changes to our gardening patterns with new knowledge and creative planning

Various tools allow us to perform tasks we could not do by hand. Unfortunately, fuel-powered machinery also produce emissions. While machinery is challenging to eliminate, here are some ways you can reduce emissions.

Quick Tips • Keep equipment well-maintained. Clean after each use. • Reduce the amount of tilling. In addition to using fuel, it exposes more of your soil to wind and water erosion and disrupts the work of microorganisms. • Mow your lawn to 4” in height to prevent evaporation from cutting leaves and shade the roots. Leave clippings on the property to improve the soil. • Do not till the vegetable garden after harvest. Cover the ground with compost after removing dead plants. • Mulch your vegetable garden instead of regularly tilling between rows. • Garden intensively in the vegetable plots. This leaves a small amount of bare soil that we can mulch with shredded leaves and grass clippings. • Reduce the amount of conventional lawn by replacing it with low grow no-mow grasses or with prairies or meadows.

Grow Native Plants Native habitats protect plants and animals in severe weather. In Climate-Wise Landscaping, Sue Reed and Ginny Stibolt write that when choosing plants that can tolerate these conditions, we help our landscapes thrive in the future. They can rebound quickly during more trying times and continue to provide the ecosystem and habitat that native insects and animals need. The deep roots of plants in prairie ecosystems have created deep, friable soils that hold water and have an active microorganism population. In native woodlands, leaf litter, downed trees, and groundcover continuously add to a compost-like layer that absorbs and holds water until it moves into the ground. This specialised habitat is home to animal forest species.

Quick Tips •Choose plants native to your region. Check that your garden meets their needs for light level, soil moisture, and soil type. •Learn the requirements that native birds, bees, butterflies, spiders, and insects need to live and reproduce. Often, that will include specific plant species. •Use ground layer plants (perennials), mid-layer plants (shrubs and vines), and trees (small and large). •A native landscape will provide pollinators for your vegetable garden.

soybeans in a no-till field Climate change cannot be far from our thoughts. We experienced unexpected weather variations in 2021, and this continues into 2022. However, we can make effective changes to our gardening patterns with new knowledge and creative planning. It’s time to address the conditions that contribute to a warming climate and plant resilient landscapes to survive serious weather events. 3

Food Forests Permaculture Practices Create Learning Opportunities, Community Growth And Enhanced Food Sovereignty

FOOD FORESTS

n 2021, the United Nations World Food Programme’s Hunger Map estimated that 957 million people across 93 countries did not have enough to eat. And yet, six years earlier, a study by the Global Forest Expert Panel on Forests and Food Security concluded food forests could play a role in complementing agricultural production.

How Food Forests Work Key to protecting biodiversity and mitigating climate change, a forest’s contribution to alleviating hunger is not well known or fully understood by many. Yet, forested gardens have produced enough to feed entire communities for thousands of years. For example, in Morocco, the food forest of Inraren is over 2,000 years old and is still producing edibles. Unlike mass-produced crops, food forests use permaculture practices focused on small scale food production. This model is ideal for small towns, remote communities with limited access to fresh produce, and urban neighbourhoods. The forests adhere to what Bill Mollison, the “Father of Permaculture”, described as the conscious design and maintenance of agriculturally productive systems with natural ecosystems’ diversity, stability, and resilience. The forests harmoniously integrate into the landscape with people, providing food, energy, and shelter in sustainable ways. Unlike traditional community garden plots managed by an individual or small group, food forests are three-dimensional edible arboretums often set within a communal landscape. This invites a collective approach to design, maintenance, and food sharing that harkens back to a time when communities worked together and weren’t dependent upon imported goods or unreliable supply chains.

In the Browns Mill region of southeast Atlanta, the city manages a growing 2,800-hectare food forest that invites the public to take what they need at no cost. In Spain, the edible forest of Juan Anton Mora was established 20 years ago with an open door policy. In Canada, these edible gardens of Eden are being planted as hubs of learning and community and provide hope that food equity everywhere is possible.

Forested gardens have produced enough to feed entire communities for thousands of years The Seven Natural Layers of a Food Forest A food forest mimics natural patterns, extending vertically and horizontally and has seven distinctive layers. The overstory, or canopy, is created by tall fruit and nut-producing trees. A layer of dwarf fruit trees follows, and berry-producing shrubs come next. Herbaceous plants transition to a layer of edible ground cover that functions as living mulch. Below the soil surface, root vegetables grow in the rhizosphere. Finally, a vertical layer of vines and climbing plants grow up the tall tree trunks seeking the sun. If mushrooms are grown, they are considered a separate mycelial eighth layer. Plants are predominantly perennial or self-seeding, returning each growing season on their own. Once established, nut-producing trees live for hundreds of years and berry bushes for a decade or more. In a food forest, there’s no irrigation or fertiliser used. Natural drainage, groundwater and precipitation supply water needs; this helps balance maintenance and costs.

FOOD FORESTS

In a food forest, there’s no irrigation or fertiliser used. Natural drainage, groundwater and precipitation supply water needs; this helps balance maintenance and costs

After harvesting annually grown crops, fields are often left fallow, allowing the soil to rest and rejuvenate. The same does not occur in a food forest. If a plant fails, it can decompose naturally, releasing bacteria and fungi that add to fertilisation and soil health. The diversity of what is planted means less competition for the same resource. Species that require more water to grow are likely to be placed near natural drainage areas at the bottom of a slope or close to a stream bed, while more drought-tolerant plants are grown elsewhere.

Fredericton’s Botanic Garden In New Brunswick, Canada, Fredericton’s Botanic Garden food forest started as a small orchard. Simi Usvyatsov, a volunteer at the garden, knew of food forests in other parts of the province and saw the potential of what the orchard could become. Working with the City, the Atlantic Permaculture Network, Fredericton Food Rescue, and the Botanic Garden Association, the project received a grant of $5,000. Last fall, an overstory layer of chestnut, hazelnut, and butternut trees was planted, forming three sides of a rectangle that will function as a sun trap for a grape arbour. The shrub layer will include Nanking cherry, highbush cranberry, gooseberry and haskap. Stephen Heard, a biology professor at the University of New Brunswick and President of the Fredericton Botanic Garden Association, sees the project as a learning opportunity more than a place to harvest and formally distribute food. He likes the idea of people being able to pick and gather what they want when visiting the forest. Still, he says the more exciting part of the project is the potential to educate visitors about permaculture and locally sustainable food production.

Vancouver Urban Forest Foundation (VUFF) Imagine orchards encircled with salmon, salal, and oso berry bushes native to British Columbia’s south coast. A canopy of oak and chestnut trees provides relief from the hot sun for fiddlehead ferns. Rhubarb lines pathways and fields of wild asparagus and sunflowers attract insect pollinators, bees, and butterflies; this is VUFF’s vision for every park throughout the city. In alignment with Vancouver Park Board’s Local Food System Action Plan, which encourages strengthening food networks within city neighbourhoods, Marie-Pierre Bilodeau, Operations Coordinator for VUFF, says they are cultivating a sharing ideology. VUFF advocates shared decision-making concerning food sovereignty, what is planted, and how it’s managed and harvested, engaging with community members, groups, and neighbourhood houses. People will be able to come and harvest freely. Volunteer groups will manage maintenance, and crops with the overall goal to serve 2tasks, INTRODUCTION the community. Trees and forests are an essential part of Vancouver’s character and identity. They are interwoven into the city’sVancouver history and culture, and continue to define our parks, neighbourhoods, and streets. What would Vancouver look like without the tall evergreen forests of Stanley Park? Or the blossoms of cherries, plums, and magnolias that define spring in many of our neighbourhoods? Trees are waypoints that mark the changing of the seasons, enhance the physical and mental health of city residents, provide food in our gardens, and support biodiversity. Urban forests are increasingly recognized as a critical part of a healthy and sustainable city. They form part of Vancouver’s “green infrastructure” that intercepts rainfall before it enters storm drains, filters airborne pollutants, shades streets and buildings during heat waves, and supports birds and other wildlife. These ecosystem services are as important as the water, sewer, and street systems that sustain the city. The urban forest will become even more important as the impacts of climate change increase.

Vancouver is a rapidly changing city with high land values and physical constraints to expansion. The city’s neighbourhoods and communities face significant challenges from population growth, urban development, and climate change. The urban forest will play an increasingly important role in Vancouver’s resilience through its contributions to both human and environmental health and well-being.

When implemented together, the Urban Forest Strategy, Biodiversity Strategy, Integrated Rainwater Management Strategy, Vancouver Bird Strategy and Vancouver’s Playbook (parks and recreation master plan) will establish a comprehensive network of green infrastructure throughout the city.

FOOD FORESTS

Unlike mass-produced crops, food forests use permaculture practices focused on small scale food production. This model is ideal for small towns, remote communities with limited access to fresh produce, and urban neighbourhoods

Saskatchewan Muskeg Lake Cree First Nation in northern Saskatchewan has struggled with the availability of fresh produce. Shipping costs are expensive, which results in higher food prices for what is available. When asked how the community saw a food-secure future, the collective answer was to rebuild connections to the land and focus on traditional growing practices that sustained them for thousands of years. In 2018, the community planted a 2.5-acre food forest collaborating with the non-profit Feed the Children. Berry harvests are used for public events, and by 2025, fruit and nut trees will be producing enough for the entire community to enjoy regularly. Ground cherries and gooseberry form the shrub layer. Mints, herbs, red and purple clover, rye, and other grasses create a lawn that enriches the soil and chokes weeds.

Steven Wigg, permaculturist and Food Security and Climate Change Supervisor at Muskeg Lake, says a small, dedicated community with a few acres of land could soon be self-reliant for their fruit, herbs, starch, and a large portion of their vegetables. Food forests are altering how communities view food production. By planting and growing according to the needs of the natural world, they remind us that if we just let it, our fragile planet will happily and successfully supply all we ask of it. 3

Unfortunately, the visionary 500 to 508, from other BD farmers or died less than one year later, leaving much organisations like the Josephine Porter of his insights open to interpretation by his Institute for Applied Biodynamics. Moreover, if the ‘bizarre’ followers like Ehrenfried Pfeiffer, Herbert Koepf, Manfred Klett, methodologies employed to make these preps weren’t and Maria Thun (whose Biodynamic Almanac (calendar is still enough, the fact that they are applied at homoeopathic used by many BD practitioners). quantities (i.e., incredibly minute amounts are spread over acres) pushes sceptics over the edge.

Time and time again, many of the award-winning of livestock, much like organic agriculture. However, the two wines of the world come from grapes grown in biodynamic agricultural systems differ in that BD farmers rely on nine specific vineyards, and that has helped get the attention of many preparations for their soil, crops, and compost to enhance soil regenerative growers. and plant quality. Professor John Reganold at Washington State University best described these preparations in the film about Biodynamic practitioner Peter Proctor, “One Man, One Cow, One Planet.” Dr Reganold begins by stating, “not even in my wildest dreams,” then pauses, “well, maybe in my wildest dreams I could come up with something like this” about Steiner’s

From choosing what days to transplant and prune to the day of harvest, many BD growers will turn to a calendar that outlines which days of the month are best to perform these tasks. Even the spraying of BD Preps like BD 500 (Horn manure), BD 501 (Horn silica), and BD 508 (horsetail) are best applied using the guidance of the astronomical-based calendar.

BIODYNAMICS

Steiner recognised that the Earth was in severe decline and expressed an urgency to get this wisdom out and apply it on as many farms as possible. To help with this, many of his followers have simplified the practices without losing the intent behind them. One such practice is Barrel Compost (Cowpat Pit), developed by Maria Thun based on Ehrenfried Pfeiffer’s BD Compost Starter Kit.

Biodynamic farming favors soil health through compost, animal and green manures, diversified crop rotations, and incorporation of livestock, much like organic agriculture

In this method, fresh manure (20kg) from a pregnant cow and some drier dung (3kg) from a pasture are mixed with some coarse basalt rock dust (500g) and about 100g of finely crushed eggshells. This material is placed in a bottomless barrel (like those used for wine) buried halfway in the soil. Alternatively, a pit large enough to hold the manure can be created using bricks. The BD Compost Preps (BD 502 to 506 - yarrow, chamomile, stinging nettle, oak bark, and dandelion) are then placed in small holes positioned in a circle. Finally, BD 507 valerian juice (about 3ml in 500ml of water is stirred vigorously in one direction for 20 minutes creating a vortex, and then in the opposite direction creating chaos that serves to “potentize” or “dynamize” the Prep) is sprinkled on the barrel compost as a protective sheath. Covered with wood or burlap, the manure is allowed to compost for about six months. When ready, about 250g of the barrel compost material would be added to 50L, enough to cover a hectare.

The barrel compost prep is best used before transplanting or seeding and serves as a replacement for compost. Shortly after, BD growers will use BD 500 (horn manure) and BD 501 (horn silica) to balance the Earthly and Cosmic forces (respectively) affecting the farm. One of the most useful yet controversial BD preps is BD 508 - Horsetail (Equisetum arvense). This preparation requires no real transformation; it is boiled fresh or dry, cooled, and then sprayed on plants (timing is critical because this prep could burn

your plants). BD 508 counters the masculine forces of the Moon (which are responsible for weed, pest, and fungal diseases) with the feminine energy of horsetail that in appearance resembles a comet. BD 508 has helped many grape growers ward off fungal diseases like botrytis and powdery and downy mildew.

Worldwide, communities of BD practitioners gather to make preparations; share interpretations of Steiner’s works, and evolve the concepts into practical applications. For example, BD 501 (horn silica) and BD 507 (Valerian) can significantly increase photosynthesis and Brix levels, which is correlated with increased drought and frost tolerance and shelf-life. Fermented and boiled teas using various plants like stinging nettle, comfrey, yarrow, calendula, chamomile, tansy, and wormwood are used to address a whole host of issues ranging from insects to plant disease to nutrient disorders. For this reason, one of the central tenets of biodynamics is to enhance biodiversity. By allowing refugia areas to grow a wide array of plants, the farmer has all the tools they need for fertilisers and pest control. If there was an urgency at the turn of the 20th century, the last hundred years have only exponentially increased the need for healing. For many of us, plants are incredibly healing in their own right. Together with biodynamics, the notion of healing our species while healing our Earth can be a closer reality. 3

More humans than ever pay attention to what we feed ourselves, how we grow our food, what we put on our skin, and the waste we produce. Some of this information may be outdated and challenging (I don’t know how you feel about leeches purifying blood, but I’m not convinced yet). Still, there is undoubtedly a wealth of knowledge that we should not forget. Many herbs and common weeds have powers that effectively fight health issues like colds, eczema, or even repelling nasty bugs. In our kitchens, people are swapping ready-made products for experimentation with homemade ones, often realising that they are far superior to the mass-produced items on the market. I have embarked upon several of these adventures in the last year, producing some of my first fermented foods, vinegar, teas and skin products. Some of these mad scientist games have resulted in weird and wonderful concoctions; others I likely won’t bother making again. Overall, the learning curve has been so much fun, and I think you should If you’ve already try making some of them.

Mustard

caught the vinegar-making bug (see past editions), you can follow the zero-waste trend and use leftovers to make delicious mustard

The ultimate ‘secret ingredient’ in many barbecue sauce recipes and the best companion for a Polish grilled sausage (in my slightly biased opinion), mustard is a condiment known in thousands of forms across the globe. If you’ve already caught the vinegar-making bug (see past editions), you can follow the zero-waste trend and use leftovers to make delicious mustard. After straining the liquid into the bottles, you’ll be left with fruit or veg pulp, making an excellent mustard base. The quantities of ingredients are approximate, and you’re better off trusting your eyes and taste buds for seasoning; we all prefer different spice levels. The main components are fruit pulp and mustard seeds, and the heat of the final product will depend on their colour. For instance, yellow mustard seeds are milder; black ones are hotter. Start by blending the pulp into a smooth mass - this may not be needed when you use soft fruit like pineapple or blackberries, but the apples need a good whizz. Next, add the mustard seeds of your choice, roughly in a ratio of pulp to seeds 2:1, and leave for a day to soak. Be sure you leave enough room in your jar as the contents will double in mass. The next day, add salt and honey to taste and some turmeric to create a beautiful yellow colour. Mix well and leave in the fridge for another 24 hours. On day three, blend everything into a smooth mass again, and season if desired – the mustard will be very hot right now but don’t worry about it, make sure that the sweetness and saltiness are to your taste. If the texture seems too thick, add a splash of vinegar or olive oil. Pack it tightly into a clean jar

Apple vinegar pulp with mustard seed

without air bubbles. The mustard is almost ready; it only needs around six weeks in the fridge or a cold cellar to mature! After this time, the heat will be milder, and all the ingredients will combine and create a unique flavour. As an unknown author from Dijon would have said, voila!

Oxymel Winter months are often harsh to our bodies, with cold, damp weather and a distinct lack of fresh, nutritious food. Oxymel is an ancient tonic that is a must-have in my household. The name consists of oxy, meaning acid, and mel, meaning honey. So oxymel is a mixture of 1:1 or 1:2 apple vinegar and honey. It sounds pungent, and if you have never had the pleasure of trying one, it’s a hell of an experience. You can enhance the apple vinegar with herbs of your choice. Doing so will add to the flavour and boost the mixture’s healing properties. Depending on what you’re aiming for, you could try macerating (steeping in liquid for about four weeks) elderberries in vinegar. This option results in an excellent cold-preventing oxymel. Adding thyme, rosemary, and cloves to the vinegar soak creates an oxymel that supports the respiratory system (thyme is perfect for nasty coughs). These mixtures are primarily used in wintertime when we need this extra boost and protection from viruses. However, the time to collect, dry, and store those precious herbs is throughout the summer, so it’s worth planning your forage.

Mustard seasoning

Many herbs are excellent for your health, but the difference between a medicine and a poison is the dose. Some are considered toxic, even in small quantities.

Fire Cider This one is not for the faint of heart! Fire Cider, as the name says, is guaranteed to cause some challenging feelings in your mouth, but it is known to be a reliable immune-boosting drink, helping to prevent and treat colds and aiding digestion. Drink it by the teaspoonful in some tea or water, and even this is a rather sensational experience. You can add it to soups and stews for some extra heat and mineral absorption (as vinegar helps break amino acids from bones if you’re a meat-eater). The original recipe from the 1970s includes fresh garlic, fresh ginger, horseradish, onions and cayenne pepper. Nowadays, fresh turmeric root, lemons, oranges, star anise and cloves are added. All those plants contain many vitamins and minerals extracted by the vinegar maceration, leaving us with a drink that no bacteria or viruses want to face.

Bug spray Many herbs are excellent for your health, but the difference between a medicine and a poison is the dose. Some are considered toxic, even in small quantities. Tanacetum vulgare, or Tansy, if we were to go by its common name, is one that even experienced herbalists will use with caution and only externally. It is, however, one of the best remedies for all sorts of nasty biting insects, thanks to a compound it contains – thujone. Tansy vinegar will destroy all skin parasites such as lice, fleas, fungal infections, Demodex mites, and scabies. When sprayed on clothing, it will deter ticks, mosquitoes, and midges, making your camping holiday fun again. You could either make such vinegar from scratch or

macerate tansy flowers in a ready-made one. This simple remedy is beneficial in woodland areas where ticks hang out or for a regular debugging of pet bedding. And if you happen to have a bad fall and end up covered in bruises, the same vinegar applied to the skin will speed up the healing process, fade the bruises away, and help reduce swelling. Curiosity and a willingness to learn about plants have always been a great advantage to humans. Repelling, attracting, and healing properties have been discovered over the centuries (although presumably with a generous handful of casualties left behind). Today, we have the knowledge left by our ancestors, coupled with a better understanding of the processes and chemical composition of plants. These tools should empower us to look around, wonder, and carefully try some of the mixtures ourselves. Not advisable for cats, though; apparently, curiosity is what kills the poor buggers.

Eco-Anxiety and The Negativity Bias What Should I Be Worrying About?

ental health experts worldwide are noticing a significant increase in people suffering from eco-anxiety; that is, feelings of despair and doom where the environment is concerned. With the effects of climate change showing themselves and the constant circuit of negative news

headlines, it’s no wonder we are worried. For some, the anxiety is crippling. Garden Culture’s Alan Creedon, a local food crusader and mindfulness teacher, offers some advice on jumping over this mental hurdle.

ECO-ANXIETY

Choose what you concern yourself with, don’t let it choose you. Eco-anxiety is a genuine phenomenon that is upsetting people all over the world. Unfortunately, it seems to have ramped up with the advent of Covid-19. The general feeling seems to be that we should be worried all the time, and if we’re not concerned, we are not acknowledging what’s happening.

Anxiety disowns our thoughts, forcing us to run away from solutions.

Fight or Flight

us nervous to think that other people might be more sorted than us!

Face Your Fear Constant anxious thoughts close our minds to other possibilities and dreams. They block potential and stop us from trying new things or challenging ourselves and being brave enough to open up to the depths of our experience.

The media portrayal of the current climate disaster and global pandemic appeals to an old part of our brain – the fight or flight part. The message often comes with the subtext that you should be worrying about this. Unfortunately, this undertone does not help us. Instead, it leads to the third part of the fight or flight scenario – we tend to freeze. We feel inertia because when we take in the new story, we can do nothing about it.

Anxiety disowns our thoughts, forcing us to run away from solutions. When we worry, we detach from the idea itself and its resolution. It’s similar to being friends with someone who hurts us; we know it’s wrong to hang out with them, but it’s a tough habit to break. However, once we stand up to the thing we are worrying about, its power over us is released.

So we worry. Sometimes, this can feel like action – because we’re involved in thinking about the event. But it is not helping; it’s simply playing into the hands of our hard-wired neural programming.

Take Responsibility

We are not to blame for our neural nature, but we are responsible for our choices. It’s good to explore this distinction. Our brains are programmed to run away. In other words, we look for the negative in every situation. “What is the danger here?” we ask ourselves without thinking about it. This is how we’ve been for tens of thousands of years. In many ways, it’s why you are alive - you are alive because people reacted quickly and ran away (or fought). Now, we use that very same brain function to run away from difficult situations in our minds. We are, on some level, protecting ourselves from harm, but that same protection can keep us from experiencing growth in our lives. Why? Because negativity bias, the part that focuses on the danger, also makes us worry and feel a ton of anxiety. We often get stuck in the negative feedback loop.

There’s Hope The great thing about this is you can do something about it! The hard wiring in our brains serves a purpose and helps us discern danger, but we can train ourselves to chill out and not be so worried all the time. How? Take responsibility for the content of your thoughts. Reroute the direction they take and remove yourself from the negative loops we so often settle into. Do this by making space for yourself. Sit for a while and think about some of your climate-related fears. Know that many people feel anxious like you. We all tend to keep our feelings a secret because it makes

We are responsible for what we think about, just as we are responsible for our actions in the world. In other words, on some level, we choose those thoughts. So force yourself to have more fulfilling ideas; it’s the kinder way to treat yourself. With some training, anyone can do this. You are not permanently stuck with your hard wiring to run from danger; it’s just the default running. You can rewire your brain to help your mind support you in your life. If you are struggling, please spend some time with these ideas. It may be of some help.

Individual Efforts Matter However you feel about climate anxiety, it is real for many people. It is critical to remember that we have the power to pick our battles. When I look at the climate disaster, I feel powerless. But what I can discern is that the environmental struggles we face are a disaster of disconnection from each other, community, the natural world, and an ever-increasing reliance on the newsfeed on our smartphones and computers. When I feel challenged by things I am powerless to affect, I go for a walk. I see if I can connect with the people who live near me somehow. We are in a crisis of disconnection; our social climate has meant we are isolated and anxious, which is reflected in (and influenced by) the news. Grounding yourself and asking what individual efforts you can make locally can be powerful ways to combat climate anxiety. It all starts with choosing what you think about; work on accepting your neural programming and choosing to look in another direction. Choose the path towards hope and connection, and then the focus on disaster can be left behind. 3

n two previous articles, we discussed some of the requirements for the successful tissue culture of plants and fungi. Some specific laboratory techniques were mentioned, but perhaps not in sufficient detail to be able

to confidently implement a good “sterile technique.” This last article in the series aims to improve upon that.

“Sterile technique” describes the many procedures that minimise as far as possible the introduction of contaminating organisms into an experiment or culture.

Here are two and rubber gloves—preferably nitrile. Before starting work, wash standard techniques: gloved hands with 70% isopropyl alcohol (isopropanol). There are many disinfectants available for household and laboratory use, but it is hard to beat 70% isopropanol for cost, effectiveness, and safety. Why 70%? A lower percentage is not as effective. A significantly greater percentage causes immediate damage (coagulation) to cell membrane proteins, which interferes with further uptake of the alcohol solution into the cell; 70% is the way to go. Even when using a flow hood, it is advisable to wipe down the work area from top to bottom with 70% isopropanol.

Hold the tool in your dominant hand, and with the other hand, carefully lift the cover from the source plate while still holding it over the medium surface. Use the tool to collect a sample from the plate and return the lid as quickly as possible. Lift the cover above the receiving plate the minimum amount required to be able to transfer the sample from the tool to the medium surface. Replace the cover quickly after the transfer is complete. Sterilise the tool.

There are no shortcuts to sterilising liquid or solid culture media. A device capable of maintaining a temperature of 121°C at a pressure of 103 kilopascals (250°F at 15 PSI) for up to several hours is required. The good news is this is well within the range of standard pressure cooker/canners and instant pots. The major limitation of

(2) Tube and flask transfers. Sterilise the tool, often a small loop in these cases, especially for liquid cultures. The flask or tube will have either a screw cap or a plug. It works the same for either a tube or a flask. Hold the tool in your dominant hand and the tube in your non-dominant hand. Use the small finger of the tool hand to remove

It so happens that a flow hood is something that can be built from scratch relatively easily, for much less than half the cost of a pre-made one the cap or plug from the tube and hold it there (Figure 2). Pass the neck of the tube through a flame. This heats the air in the neck and forces it outward. Extend the tool into the tube to collect or deposit a sample, flame the neck again and re-attach the plug or cap. Flame the tool to sterilise it and let it cool for the next operation. Many would consider a sterile culture hood an essential piece of equipment for tissue culture. Unfortunately, commercial units run from $500-$2,500, although some small tabletop models are now available for less than $200. It so happens that a flow hood is something that can be built from scratch relatively easily, for much less than half the cost of a pre-made one. Figure 3 shows a small tabletop unit consisting of a plexiglass work enclosure and a top-mounted fan that blows through several MERV 13 filter material layers. The efficiency is not quite up to that of a HEPA filter at 99.97% at 0.3 μm but is somewhere around 95%, which is a significant improvement over no filtration. The enclosure is fabricated from standard extruded aluminium T-slot bars and hardware. It was originally built to use a small vacuum cleaner HEPA filter purchased at a garage sale for a dollar, so the filter is mounted in a small opening on the top of the cabinet. Not ideal, but it works. Usually, you want the air blowing linearly forward from the back (laminar airflow) so that any airborne particles are flushed straight out of the work area with minimum turbulence.

A better design with a HEPA filter, although not as space-saving, is shown in Figure 4. This unit has a plywood plenum (an enclosure made to hold low-pressure air) to keep a top-mounted fan with speed control. Once again, the work zone is a plexiglass enclosure in a T-slot frame. The plenum is mounted to the filter, and the filter is mounted to the enclosure as shown in Figure 5. Running this unit with a set of nine exposed nutrient agar plates for a half-hour resulted in zero per cent contamination. For anyone interested in pursuing plant or fungal tissue culture, the techniques we have discussed are covered and demonstrated in many articles, books, and websites. So do more research, get some equipment, and build some of your own. 3

A Disease Devastating Many Industries

ops Latent viroid (HLVd) is the new kid on the block, causing devastation in urban gardens everywhere. Infected plants often don’t show visible signs of disease, making detection very tricky.

If a plant does show symptoms, you will likely notice the yellowing of areal par ts, stunted growth, shor ter internode spacing, looser flower formation, and reduced trichome production and biomass. Like any successful pathogen, HLVd won’t kill the plant but will dramatically reduce yields. High-tech methodology is needed to eradicate this pathogen from a crop and grow room.

HLVd’s Behaviour

References

HLVd has been shown to cause an increase in secondary metabolites such as monoterpenes, terpene epoxides, and terpene alcohols(1). However, it also leads to a decrease in bitter acids such as alpha acid, colupulone, and xanthohumol, which are responsible for the flavour in beer. In a study on three hops varieties, infected plants consistently showed a decrease in sesquiterpenes and terpene ketones, along with a significant increase in the terpenes β-pinene, Linalool and Geraniol. The study focused on biosynthesis and regulation genes by looking at how the viroid regulated particular gene expression within the plant. Researchers found that HLVd downregulated the genes involved in the biosynthesis of bitter acids and terpenes enzymes. Essentially, this pathogen taps into the genetics of the plant, switching genes on and off. By infecting the plant with HLVd, a different secondary metabolite profile could be achieved.

Gardening, much like painting, is just a bunch of hard work that may or may not end in some beauty. Plant Babies

Let’s be honest, push-ups are pointless. If I am going to be active, it has to be with a purpose. This isn’t a prison yard, it’s an acre of land, so why not work out with Mother Nature? I spent the better par t of last summer repurposing a massive tree we had to cut down into raised garden beds. I went through two chainsaw blades and broke a finger, but all that time in the garden had me sleeping like a drunk baby. Whether you are planting shrubs or clearing land, it’s all considered garden therapy to me.

Some people take pride in their children and some bachelors, like myself, take pride in their cultivars. A baby’s first steps and watching my clones take root are on an even playing field. I think we may have inadver tently pinpointed why I’m single. Moving forward. What I was trying to say was, that taking pride in one’s hobbies is impor tant. It’s not therapeutic if you don’t enjoy having sheep manure under your fingernails or breaking a sweat. Gardening, much like painting, is just a bunch of hard work that may or may not end in some beauty.

GARDEN THERAPY

Before you go nuts, stop and smell the roses or whatever it is you have in the garden. Be kind to yourself and happy growing.

I spent a large par t of my life succeeding and failing at painting, so I know what I speak. I have had fewer failures in the garden; how therapeutic!

Anyone who has sur vived a dark Canadian winter can tell you that by the end of the season your mental health has taken a kick to the nuts. The sooner the sun comes out, the sooner we can all get to our therapy gardens. Even our dogs can’t wait to get out there and help us by dropping little nitrogen bombs by the rose bushes.

Food Stress Finally, one of the most therapeutic aspects of them all is harvest. Having a bounty of your favourite plants and veggies does wonders for your morale. There is something about paying inflation prices for tomatoes that doesn’t sit well with me. Every summer salad means more money in my pocket and less financial stress to deal with. Food stress is a real thing. Navigating the aisles of your grocery store are more and more daunting due to sticker price shock.

In session Let’s all wash the winter’s boogers out of our eyes and start planning our summer therapy sessions. I already have my next generation of plants started on the counter in the kitchen where I make my morning tea. That five minutes I get to spend with them while the water boils are a shot in the arm I need to clock into the day job.

WAYS

To Boost Productivity In Small Grow Rooms A limited amount of growing space doesn’t necessarily mean small yields. There are several ways to ensure a productive grow room, whether you have a greenhouse, a grow tent, a decked out shipping container (see page 30) or basement operation. Get started with our list of 5 Cool Ways To Boost Productivity In Small Grow Rooms.

Environmental Control

Whether large or small-scale growing, your entire operation can go downhill fast if any little thing goes wrong. Environmental control is essential to a healthy crop. Growers need to stay on top of air quality and temperature and humidity swings. Plants can be damaged and yields reduced if the room becomes too cold or hot, and high humidity can lead to powdery mildew, fungus, and even plant rot. If you don’t own a thermometer/hygrometer, get one with a max/min feature so you can understand your grow room’s patterns. Also, selecting the appropriate HVAC equipment for your space is a must.While the selection process can be overwhelming, there’s no way around it. If you need some help, Adam Clarke offers some excellent advice in his article on page 62.

Collecting Data

So you’ve equipped your grow room with everything you need for environmental control; now what? Monitoring and collecting data can help push your plants to the next level! Modern digital technologies can help farmers and home gardeners avoid expensive mistakes and crop failure. Keeping track of the air quality gives you essential information about how your room performs and how the plants respond to various conditions, allowing you to make adjustments as needed. Invest in some sensors to monitor everything from temperature and humidity to VPD, CO2, and light levels. You can also collect information on water pH and EC monitoring, and set timers for fans and lights. Beyond collecting data, simply spending time with your plants will go a long way. The better you know them and what makes them tick, the better they’ll perform.

about the benefits of collecting data in the Garden Culture archives! Data-Driven Cultivation: Crunching The Numbers In The Grow Room, by Tom Forrest, is a great start.

GREEN ADVICE

Predator Insects

Indoor growing spaces may be protected from the elements, but they will still fall victim to pests. There are many ways to prevent nasty bugs from getting into the grow room and decimating your plants, such as releasing biological controls or beneficial predators! Ladybugs, green lacewings, damsel bugs, and assassin bugs will happily munch on aphids. Let them loose in any grow space, and they’ll be sure any sap suckers won’t feast upon your plants. Parasitic wasps and predatory mites can help with whitefly, spider mite, and caterpillar infestations. You can order boxes containing predatory bugs online; it’s recommended to purchase more than you think you’ll need as they often disappear after all of the pests are gone.

Garden Culture’s Rich Hamilton offers advice on controlling whitefly and spider mite infestations on our website! Check these two articles out!.

Preventing whitefly infestation

Spider mite

Clean Bean

Your bedroom might be a mess, but don’t let this trend continue in the grow room. This is not the place to let things go; a grow space needs to be kept sparkling clean if you want to keep your plants healthy. That means cleaning up any substrate that’s spilt from your pots; don’t let water sit on the grow table or floors, and remove any debris that’s fallen from the plants. Use dust filters in the ventilation system to keep pests from getting into the room and reserve a set of clothing to be worn exclusively in the indoor growing space and nowhere else. Various horticultural oils will create barriers on the plant leaf and prevent pests from settling in. Be sure to thoroughly check and isolate all new plants for a couple of weeks before introducing them to your space. High heat and humidity levels offer breeding grounds for pests and disease, so keep those in check. Finally, inspect your plants regularly for any signs of change; prevention is the best medicine! (PRO TIP: After you’ve cleaned the grow room, go make your bed.)

Maximise Space

Indoor growing space is limited, so it’s essential to take full advantage of the room you do have! Screen of Green (SCROG) will help you achieve an even canopy by stretching the grow horizontally instead of WAY up. As a result, plants will get an even distribution of light and better ventilation, boosting productivity! Place a screen about half a foot above the growing medium and gently weave the plant’s branches through it as they grow. Netting, stakes, and horticultural trellis will help support taller growing plants or train others to grow up instead of spilling out onto the limited floor space. This process will also help with proper aeration, reducing the chances of plant disease. Don’t forget to invest in some vinyl stretch or soft twist ties to secure branches to the trellis. Finally, consider intra-canopy lighting to increase yields. When used in combination with overhead lighting, adding lights within the plant canopy can lead to better results in the garden. 3 79

On the Road To

South Africa J

onah Tacoma writes about his experience at last month’s Cannabis Expo in South Africa, the largest event of its kind on the continent. The event offers a platform where experts and enthusiasts from around the world can come together and share knowledge and passion for the plant’s many medic-

inal, agricultural, financial, and lifestyle benefits. Jonah got to take in everything this burgeoning market has to offer alongside Garden Culture’s owner and founder, Eric Coulombe.

CANNABIS EXPO SOUTH AFRICA

Clicking on my seat belt, I pulled my headphones over my ears and prepared for takeoff. The destination was Cape Town, but first, I had to get through Qatar, a small Arab country situated along the Persian Gulf and famous for its strict anti-cannabis laws. Possession of cannabis in any amount carries a harsh minimum mandatory sentence of four years in prison and simply having THC in your blood is all they need to put you away.

I felt more at home in this environment, surrounded by farmers willing to risk everything, than I did at an expo full of suits

I learned all of this afterward, of course, spending my time in Qatar chatting about my cannabis business with an Iranian man who had been kind enough to share his box of dates. He listened eagerly, eyes raised as we sat idly munching in one of the many public smoking lounges in Doha International.

Destination: Cape Town Boarding the 787 Dreamliner bound for Cape Town, I once again settled into my preflight ritual. The Cannabis Expo South Africa had barely been on my radar, only brought to my attention by my longtime friend and partner, Jair Velleman. He fell in love with the South African scene a few years ago; he teamed up with Buzz, a Johannesburg local and veteran event coordinator, to help put on the Continental Cannabis Cup. The unofficial event within the event was pitting a cross-section of South Africa’s growing community against each other in a blind competition judged by the public. Once I arrived in Cape Town, I begrudgingly slid $650 Ran to the airport taxi driver, reasonably confident I had been swindled. Even at 6 a.m., the views looked more like Malibu, CA, than the wilds of South Africa that I had imagined. My home for the week was 20 Theresa Drive, a ten-bedroom private mansion overlooking False Bay that Jair had rented out. His guests included an assorted but illustrious cast of global cannabis enthusiasts for a meeting of minds.

The History of Cannabis In South Africa The Apartheid government criminalised cannabis in South Africa in 1922. Strict prohibitionist sanctions and criminal penalties for the use, possession, or cultivation of cannabis had been put into place almost overnight, stifling the Dark Continent’s long-time relationship with a once sacred plant. Outlasting the government that created them, these laws would remain for nearly 100 years, eventually struck down by a constitutional court ruling in 2018, which abolished them completely while setting a basic framework for legal cannabis in SA. Avoiding the long cue in front of the Expo, we retrieved our press passes and headed into the fray. I was almost embarrassed at how low my expectations had been. One lap and I knew this was an emerging market. Cannabis is native to Africa and attempts to control it have been around since the 1680s. By all accounts, cannabis history was much deeper here than almost anywhere in the world. So it should have been no surprise that the business revolving around one of the world’s oldest cash crops would be booming, even in Africa. Especially in Africa.

The Expo Exceeding Expectations The trip from Seattle had taken 25 hours in flight time alone, which I had hardly calculated when booking. After a half a dozen joints and some routine pleasantries, I found myself immediately thrust into day one of the Expo. I surveyed the crowd outside in open amazement. So far from what I imagined, the Cannabis Expo South Africa could have easily passed for a Cannacon or an early Champs in the United States. Held inside a casino event centre, the Expo had all the modern trimmings and a healthy marketing budget to match, made evident by miles of highway ads and radio commercials that seem to be playing on almost every local station. I would find out later that this was the sixth such South African Expo.

Arjan from Strainhunters was wrapped in conversation as we entered, greeting me with a handshake and a smile as we passed. He was one of the more illustrious guests at the Cape Town mansion, and I was interested to see what he was like outside of the few dozen business interactions we’d shared over the years. The next day was a blur as we did our best to attend the event while also exploring Cape Town, which we had discovered (much to our delight) is home to many warm-weather penguins. On day three of the Expo, only me and Arjan from Strainhunters

CANNABIS EXPO SOUTH AFRICA

Eric, the owner and founder of Garden Culture Magazine, were left standing.

We often joked that as members of the travelling cannabis scene, we had come from the future, able to see the course of cannabis legalisation as it slowly took hold

I positioned myself in the outside smoking section of the casino venue, assuring Eric that I would be there when he got back from his rounds. I was jet-lagged and hungover, and I would never have gotten up if he hadn’t plied me with a cappuccino in bed, an act of kindness that I could not ignore. I was there to support him, even if it was mostly in spirit.

By mid-day, the African sun was in full effect, and I squinted into the streaming light, trying to absorb as much of it as I could stand. The mushroom honey (which Eric had deftly avoided) was starting to kick, and I wondered how much longer I could smile and nod without being detected, the irrational fear of anyone who decides they have taken too many hallucinogens in public. I relayed the crux of my crisis to Eric, who was nice enough to ensure our exit but not before dragging me around for a few extra laps. By the time the Continental Cup was underway that night, I had entirely worn off my buzz, and we departed for the venue fashionably late.

The Continental Cup About 100 people filled the medium-sized room to near capacity, with most of the action around a small bar where dabs and warm drinks were served. A rotating wheel displayed each flower entry, identifying them by number. I grabbed a room-temperature Black Sail and found a spot to roll a joint as things got fully underway. When the awards were ready to be announced, the room had finally begun to cool with the evening air. Buzz called the crowd to a quiet without a microphone, his uniquely South African accent adding emphasis to the words as he spoke.

I felt more at home in this environment, surrounded by farmers willing to risk everything, than I did at an expo full of suits. There was something familiar about this crowd that I found comforting. We often joked that as members of the travelling cannabis scene, we had come from the future, able to see the course of cannabis legalisation as it slowly took hold. We took turns saying our piece as sponsors before the winners were announced, and I made sure to say one thing during my time. I said they had something beautiful in South Africa, and they needed to protect it. As the night went on, each winner was recognised; their peers celebrated their accomplishments one by one. That is the magic of the cannabis community; it doesn’t matter what you are, just who you are and what you want to be. We spent the next few days touring large American-style grows in the hills outside of Cape Town and availing ourselves of the finest dining we could procure, a favourite pastime of Jair. Then, finally, after a heartfelt goodbye to our Cape Town friends and the rest of the mansion crew, I took to the skies once more. This time, for the farmlands outside of Johannesburg and what I hoped would be an even more authentic South African experience at the mysterious Jazz Farm. To be continued. 3
