Feature Task: Start a garden journal

Annuals

Garden Beds

• It’s a great time to start seeds indoors for many annual flowers. Plan to transplant them into the garden in May after the danger of frost has passed. • Cold-tolerant annuals work well in beds, pots or hanging baskets. Containers are always a great option for instant results.

• Remove any weeds that may have sprouted last fall. • Re-edge garden beds. In the process, remove weeds and grass that has invaded the beds.

Bulbs: Spring-Flowering • The first sign of spring is blooms of crocus, daffodils, tulips and hyacinths. For gorgeous blooms year to year, fertilize when you first see green tips breaking through the ground. Continue fertilizing until the foliage dies back after blooming.

Bulbs: Summer-Flowering • Start cannas and other summer tender bulbs indoors to get a head start on the season. Use 6- or 8-inch pots, plant them and leave them in the basement. Water as needed. When the shoots are 2 to 5 inches tall, move them to a bright, but indirectly lit window. Take them outside as soon as you can. Don’t expose them to temperatures below 50 degrees. Fertilize twice a month until they can be transplanted into the garden.

General • Sharpen and oil shovels to reduce rust problems. Check rakes and cultivators for bent tines. Check the heads on all tools for tightness; fix or replace as required. Sharpen blades on pruners, loppers, shears, and lawn mowers. • Don’t step on soil that is still too moist! To check it, take a handful of soil and squeeze it into a tight ball. Press the soil ball with your fingers. If it doesn’t break apart easily, it is still too moist—wait for it to dry out.

Houseplants • Continue to lightly water cacti and succulents. Water cacti lightly once a month, and succulents twice per month. • If you are growing citrus as a houseplant, apply its spring fertilization. Use a flowering houseplant fertilizer that is high in phosphorus, diluted to half its recommended strength.

Evergreens

Lawns

• Prune any obvious winter damage. All damage may not yet be visible, so continue to prune as other damage reveals itself.

• Begin fertilizing the lawn, either when the forsythia shrubs bloom or the lawn has been mowed once. • If there was a crabgrass problem last year, apply a pre-emergent treatment with the first fertilizer application. It’s not necessary if there wasn’t a problem last year. • When re-seeding bare areas, be sure to use the proper treatments. Some pre-emergent fertilizers stop both crabgrass and the new seed you’ve just sown from germinating. If you’re re-seeding the lawn, be sure to select the appropriate lawn fertilizer without crabgrass preventer.

Fruit Trees • Prune apple trees to wide branch angles to encourage air movement in the center of the trees. Remove branches growing on the underside of limbs, as well as water sprouts (shoots growing vertically out of a branch). • On stone fruits such as cherry, peach, plum and nectarine, only prune out dead or weak branches.

Make plans to document the gardening season this year by starting a garden journal. It doesn’t have to be fancy—just a place for photos and notes. A three-ring binder with clear plastic sheet protectors works great. If you’re computer-savvy, a digital record is great; complete with photos throughout the seasons. Consider using Pinterest and create boards to track your garden year to year online. Organize the journal any way that works for you. The most common is monthly. Start by taking photos of the landscape, individual garden beds, and even individual flowers and weeds. Label and date

Perennials • Remove to near ground level any shoots or seed heads that remain from last year. • Give the beds a good raking, removing any spent flowers, weeds and loose debris. Mix in organic matter like compost, manure or pine bark fines.

Roses • Prune out and discard any canes showing signs of disease. Do not put diseased canes on your compost pile. • Once the bright yellow forsythia starts to bloom, it’s time to start caring for roses again. Help control black spot and other diseases with an early fungicide spray. Remove all the leaves and any debris. Spray all the canes and a foot out from the canes. Fungi can overwinter in the soil, so neglecting this ground spray can lead to more infection later in the season. • Prune out any crossing branches and any branches that grow toward the inside of the bush. All rose canes should grow out of the center of the plant, not back into it. This will encourage air circulation and slow down the spread of disease.

Seeds • If you’re starting your plants from seeds, make sure they’re ready for the garden at the end of May. Count back from the day you want to plant to determine the date to start them indoors. Seeds like bottom heat to germinate, and you’ll get better results by putting your seedling trays on a special heating mat to give them a needed hand. Harden off any seedlings by getting them used to being outside gradually before you plant them into the ground.

Shrubs & Trees New members always welcome Visit our website for program schedule

• Don’t prune any spring-flowering trees until after they’ve bloomed, or this spring’s flowers will be pruned off. Mark any branches that should be pruned, so you can find them later, after the tree has leafed out. Prune any branches that cross, or grow back in toward the inside of the tree.

the photos and place them in the journal. Make notes of what’s blooming well or anything you’ll want to move, divide or donate to another gardener later in the season. If you planted anything that month, add the color picture tags of the plants so you’ll have the exact variety name. You can keep a list of tasks that need to be done in the garden that month, and record when fertilizing, pruning and dividing was completed. It will be a handy reference for next year. Leafing through the journal is a great way to get inspired during the long months of winter.

Be sure only to prune to the branch collar, the slight swelling right next to the trunk of the tree. If the branch collar is cut off, you’ll be cutting off the site where most of the healing growth comes from. • Before pruning shrubs, know when they bloom. If you prune spring-flowering shrubs now, you’ll remove the flowers. Prune spring-flowering shrubs, such as lilacs and azaleas, once they’ve finished blooming, but before the 4th of July. • Summer-blooming shrubs, such as spirea, potentilla, and rose of Sharon, bloom on this year’s new growth and a welldone spring pruning promotes more new growth. Take off 1/4 to 1/3 for more compact plants with more flowers in the summer. A good, long-lasting organic fertilizer would be beneficial. Apply toward the end of the month.

Trees • Check trees such as oaks, maples, and crabapples for gypsy moth egg masses, which are a light tan with a felt-like texture. If found, gently scrape them off the bark, drop into a jar of soapy water, let soak for three days, and discard in the trash.

Vegetables • When the soil is ready to work in, sow cool weather crops like peas, spinach, endive, lettuce, radishes, carrots, and beets. If desired, repeat 2 or 3 sowings at 2- to 3-week intervals.

Vines • Summer- or fall-blooming clematis can be cut back to within inches of the ground to promote new growth and encourage blooms later this year. • Don’t trim spring-blooming clematis varieties until after they’ve finished blooming. • An application of slow-release organic fertilizer will get vines off to a healthy start.

Hydrangeas for small spaces

Garden mulches

Flower buds start to open in winter

What kind of mulches are best for landscaping? J.C., Milan The best mulches are those that are natural and biodegradable. Use nothing that is dyed a color or artificial, such as ground rubber. Look for double- or triple-shredded hardwood. You can also use pine needles or pine bark fines. As they decompose, they enrich the soil by adding nutrients that plants can take up through their roots. Mulch also insulates the soil, reducing temperature fluctuation, and reduces moisture loss during dry spells. In addition, it prevents weed seed germination by inhibiting sunlight from reaching latent seeds in the soil. Shredded wood or pine mulch is meant to biodegrade and be refreshed about every three years. Avoid shredded or chipped pallet wood or construction lumber as these may have preservatives or other toxins in them. Landscape fabric with stones on top is not mulch; it does not biodegrade nor adds any nutrients to the soil. It becomes a nuisance to keep clean of leaf debris that can provide a medium for weed seeds to germinate. Ground rubber advertised as mulch is in the same category as stones. It does not biodegrade and could potentially harm the soil chemistry. Stone and rubber make great footpaths, but not garden mulch. If your garden beds are conducive to “green mulch,” consider using low, prostrate perennials such as creeping sedums (for sunny areas) to help insulate the soil and prevent weed seed entrance. Ajuga is a good shadetolerant surface spreader that does not interfere with the health of the landscape plants but can also give you flowers and colorful leaves. Strategic placement of these groundcovers with regular mulch can add to the interest of your gardens.

My rhododendrons and hydrangeas seemed to have started budding out over the winter in January. Is there something I should have done to protect them from the freezing winter temperatures that remained? J.K., St. Clair Shores Rhododendrons and hydrangeas are responsive to the change in day length as well as light. It is quite normal to see them start to respond to those subtle changes when we think nothing should be happening at all. Their flower buds will slowly increase in size until it is the right time and temperature for them to break open. If they are planted in protected areas where a microclimate exists, they may respond more quickly due to trapped heat and less exposure to desiccating winds. Most hydrangeas are deciduous but rhododendrons are broadleaf evergreens—they do not shed their leaves. To protect them over the winter and the coldest months, it is advisable to spray them in fall with an antitranspirant to reduce moisture loss through the leaves. That moisture cannot be replaced since the ground is frozen. When we do get those unexpected warm days, it would help to actually water them. If you are seeing bud swell, then the roots are working and sending nutrients and signals to the buds. Giving them supplemental water even when it is relatively cold can help thwart shock to the plant’s system and bud desiccation.

Replanting new tree in same place as previous tree We had a huge box elder tree removed last spring (5-foot diameter and roughly 60 feet tall). The trunk and the majority of the very large roots were well ground down. We would like to plant another tree in the general area since it is such a visual loss and also to partially screen a treehouse. The area gets full sun and is near oak trees. Things to be wary of? G.M., Dexter The answer is going to vary for nearly every individual situation. The easy answer is “no”: fresh soil is best and you should avoid planting a new tree in the same spot as a large tree. I usually recommend 6 to 10 feet away depending on the site attributes. The previous tree may have depleted existing nutrients, sawdust from grindings can alter nutrient balance, and large roots outside the immediate planting area can someday inhibit new root development. Obviously roots from a very large tree will fill a wide area, so they cannot be avoided altogether, but try to avoid or remove the larg-

I need a hardy hydrangea for southeast Michigan that will stay, or can be pruned to stay, below five feet tall and has pink or pink and white flowers. Can you recommend a few? K., Saline Thanks to many hybridizers, we now have several hydrangeas that withstand Michigan’s climate and can tolerate both sun and shade. The first group is smooth hydrangea (Hydrangea arborescens). An improvement on the traditional mophead ‘Annabelle’ is Invincibelle Ruby, which stays about 3 to 4 feet tall and often reblooms. They like part sun to part shade, but will underperform in heavy shade. It has rich pink blossoms with blue-tinged leaves. Bred for stiffer stems to prevent flopping, you can cut these back in late winter to early spring since they set flower buds on new wood. There is also a dwarf called Mini Mauvette, which only reaches three feet and whose blooms are soft pink to white. The second group is panicle hydran-

est roots near the new planting site. However, sometimes a site is just “too perfect” for one reason or another and you simply must replant there. This can be done but is going to require more time and effort. The entire planting zone (2-1/2 times the width of the root ball) should be ground as extensively as equipment will allow. Then, as much of the mixed grindings and soil as possible should be removed and replaced with fresh topsoil. Since you have already gone to this much trouble, go one step further and blend in compost with the topsoil. This extra care and preparation, along with proper post-planting care, should allow a replacement tree to thrive. With that much space to work with, you have a very wide variety of replacement options available. Look to see what tree species thrive nearby and/or discuss with a qualified arborist or landscape professional. —Answer provided by Dan Schwartz at The Davey Tree Expert Company in Wixom, MI.

Deterring squirrels from feeders Is there a way to keep the squirrels from totally monopolizing my bird feeders over the winter? P.M., Pinckney Take a hard look at your feeder locations. First, do not provide any aerial or ground launch pads, like trees and shrubs, garden walls, terraces, grills, or furniture. If you use a pole feeder, put a shield on the pole to prevent access from the ground. There

gea (Hydrangea paniculata), referring to the cone-shaped blossoms. These also set flower buds on new wood, can be cut back in late fall or early spring, and come in whites and variations on pink and rose color. They tolerate sun nicely with some consistent moisture. Look for Little Quick Fire, which is a deep rose to pastel maroon and stays well below five feet. Strawberry Sundae has both white and pink on the same blossom and grows 4 to 5 feet. The third group is oakleaf hydrangea (Hydrangea quercifolia), so named because the leaves look like broad oak leaves. They tolerate sun to part shade, but set their panicle flower buds on old wood. The best time to prune and shape these is immediately after bloom. Look for ‘Ruby Slippers,’ a dark pink variety, which reaches 3 to 4 feet. The fall foliage color is a rich red mahogany, making an excellent contrast to its fellow hydrangeas. Plant it with ‘Munchkin,’ which is white and fades to blush pink.

are broad, cone-shaped baffles that attach to the pole but are tippy enough that the squirrel cannot climb around them. There are also overhead domes and baffles to prevent squirrels from dropping down on the feeder from above. Another preventive measure is a springloaded torpedo shield that attaches to the pole. When the squirrel climbs up and tries to grab the device, the spring inside the cylinder shape is compressed and as the squirrel struggles, it releases and dismounts the squirrel. There are also feeders that have a drop-down door over the seed supply. You can set the weight limit that triggers the door to allow the featherweights but that shuts out the robust squirrels. If you’ve bandit-proofed to the best of your ability, consider an alternate location where you can ground feed the squirrels and distract them from your feeders. Look at the feed you are providing as well. Almost every bird likes suet and shelled peanuts. Squirrels do not go for suet. They like sunflower, cracked corn, and nuts. There are peanut feeders designed with one inside the other, so that the squirrel cannot reach inside the cage for the nuts, but the birds can go right in. With a multi-pronged approach, you can be relatively successful keeping out the flying thieves. Answers provided by Beverly Moss, owner of Garden Rhythms.

Vertical Vegetables: Simple Projects That Deliver More Yield in Less Space by Amy Andrychowicz Growing vertically is the secret to making the most of your space; when you grow upward rather than outward, you will double or triple the yield from your small-space garden. With practical principles and background information you’ll need to start, the author shows you how to build nearly two dozen growing structures, including trellises, arbors, archways, wall pockets, towers, and more. Freestanding or wall-hung, the projects also reflect a wide variety of building materials, including dimensional lumber, metal rebar, fabric, and even “up-cycled” everyday objects. Vertical Vegetables (Cool Springs Press, 192 pages, $24.99) also includes lists of plants that are best suited for vertical growing. This project book will guide you to more garden produce and improved outdoor living in any space, from tiny and urban, to large and sprawling.

Rodgersia

Eric Hofley / Michigan Gardener

Rodgersias are grown primarily for their striking, bold foliage.

odgersias are dramatic perennials best known for their striking, architectural foliage. Although the midsummer flowers are attractive, they play second fiddle to the imposing, highly textured leaves. Depending on the species, individual leaves can reach three feet in length, with mature plants attaining a height of four feet including the flower stalks. All rodgersia species are native to Asia, particularly China, except for Rodgersia podo-

phylla, which occurs naturally in Japan and Korea. In their native habitat, they can be found growing along streams and in shady moist woodlands. Rodgersias were introduced into Europe in the mid 1800s, becoming established as ornamentals in the U.S. in the early 1900s. Currently, botanists recognize five distinct species, all of which are horticulturally significant. Their

species names often give clues to the unique appearance of their foliage.

Species

Karen Bovio

R. aesculifolia – Foliage resembling that of horse chestnut (Aesculus). (R. henrici was once listed as a species, but is now considered to be a variety of R. aesculifolia.) R. pinnata – Compound foliage, pinnate in formation (leaflets ar-

ranged along a central stem). R. podophylla – Derived from the Greek “podo” meaning foot, and “phyllon” meaning leaf. R. sambucifolia – Foliage resembling that of elderberry (Sambucus). R. nepalensis – Referring to its origins in Nepal; this species is far less common in cultivation. continued on page 18

R. podophylla ‘Braunlaub’ continued from page 16

Terra Nova Nurseries

‘Bronze Peacock’

In looking at the flowers of rodgersia, it is easy to see their similarity to those of astilbe and goatsbeard (Aruncus), two other members of the saxifrage family. The flowers of R. aesculifolia, R. podophylla, and R. sambucifolia—all white flowering—resemble those of their popular relatives due to their light, airy, triangular-shaped panicles. R. aesculifolia var. henrici exhibits thicker, sturdier flower stems, with multiple flower clusters arranged in tiers. The flowers of the henrici form are often pink, as are those of R. pinnata. The color comes from the sepals and stamens; the flowers don’t have actual petals. The seed pods may also develop pink, coral or red coloration.

Cultivars While all rodgersia species are ornamental in their own right, hybrids can offer even more ornamental qualities. All of the species cross readily with one another, making this genus a plant breeder’s delight. Many cultivars are hybrids or variants of R. pinnata, which breeders utilize to impart deeper pink color to the flowers and bronze tints to the foliage. While some varieties emerge bronze in spring, they may fade to green during midsummer. Breeders are working to achieve longer-lasting bronze foliage color, along with showy pink flowers. ‘Bronze Peacock,’ ‘Candy Clouds,’ and ‘Chocolate Wings’ are excellent examples of this color combination. continued on page 20

With an N-P-K of 15-0-7, Grass Magic contains primarily organic materials with a small addition of urea to allow for a quick green-up in the spring. Unlike most lawn fertilizers, it also contains kelp, seaweed, and beneficial soil microbes to help grass plants better absorb the nutrients. Grass Magic lasts for 12 to 16 weeks, so its nutrients continue to be effective for much longer than water soluble fertilizers, which release their nutrients in a brief spurt after water is applied. This often causes stress to the grass by forcing growth at the expense of root development and plant vigor. In addition, the insoluble nature of Grass Magic is far less susceptible to leaching and run-off than soluble fertilizers.

‘Bronze Peacock’ continued from page 18

Growing rodgersias in the garden Rodgersia is typically thought of as a shade plant, but their real requirement is consistent moisture. The large leaves need plenty of water to keep them looking perfect, especially since foliage is their most important ornamental feature. While all rodgersias require rich, moist soils, there are some slight differences between the various species. In nature, R. pinnata often occurs in moist grasslands; it is quite sun tolerant provided the soil does not dry out excessively. It is the most adaptable species and usually performs well in average soil that is kept well-watered. Highly ornamental foliage and flowers, along with

its relative ease of culture, make this a species that is often found in garden centers. At the other end of the spectrum, R. podophylla is the least forgiving of drying out—its thinner leaves are more prone to desiccation and consequent browning of leaf edges. It is the species most tolerant of wet, boggy soils, and the least tolerant of full sun. This species increases by shallow rhizomes, making it excellent in large settings where it can be allowed to spread. However, it and R. nepalensis are not commonly available in nurseries; you might need to purchase them from mail-order sources. R. sambucifolia is the smallest growing of De Vroomen Garden Products

continued from page 20 the rodgersias, reaching about two feet, making it a good candidate for smaller gardens. R. aesculifolia and its variety henrici make imposing specimens that may reach six feet tall under ideal conditions. They can be used in more formal settings, in the way one would use statuary, or can provide interest as punctuation marks among the many other, perhaps less dramatic, plants. Companions should be selected based on similar moisture and light preferences, and could include cardinal flower (Lobelia), globe flower (Trollius), meadowsweet (Filipendula), meadow rue (Thalictrum), ligularia, camassia, Japanese primroses, royal and cinnamon ferns, large hostas and, of course, its relatives astilbe and goatsbeard (Aruncus). Rodgersias are not prone to any insects or diseases. Most disfigurements are due to improper siting: soil too dry, or conditions too windy or sunny, which will mar the foliage. Like all members of the saxifrage family, they appreciate fertilizer and will look stupendous if provided frequent applications of mild liquid fertilizer, or monthly applications of dry, organic, low-analysis fertilizer.

that plants are well hydrated at the time of fertilizing and continue to supply water for a few days afterwards. Avoid fertilizer application during dry spells. All rodgersias are hardy to at least zone 5, with R. podophylla occasionally listed as zone 4, and R. aesculifolia as zone 3. However, even though these plants are reliably root hardy over the winter, their newly emerging foliage is susceptible to late spring frosts. The plants have built-in protection against spring frosts due to their very late emergence (in Michigan, mid to late May), but occasionally

a late frost will blacken the new leaves. Wellestablished plants recover quickly, but young, newly planted specimens should be protected if leaves have emerged and a serious frost is expected. Patience will be rewarded when planting rodgersias. They are not known to be fast growers, but the mature plants always make a statement in the garden. The combination of impressive size, uniquely shaped and coarsetextured foliage, and attractive flowers creates a presence that is sure to be noticed.

Historic stone walls in the garden Dennis Purcell and Judy Parsons used a Cold War-era bomb shelter as a handsome garden feature

magine feeling the need to build a shelter to protect your family from nuclear bombs. During the Cold War, many Americans built these shelters as the threat of nuclear fallout from those bombs was very real and terrifying. Thankfully, they weren’t needed and today the bomb shelter built on this Washtenaw County property in the late 1940s is a focal point in a beautiful garden. Also making a statement are the many rock walls built to hold back the earth and terrace

Above: This beautiful stone wall was actually a bomb shelter that was built into this hillside in the 1940s. Now a storage shed, it is flanked on either side by perennial beds and is a focal point in the beautiful garden of Dennis Purcell and Judy Parsons.

They weren’t only that shelter created so long ago out looking for a home—they wanted of fear of the possible, have become the atmosphere of the lake to be the backbone of not fear, but peace right as well.

When they bought the house, it Steinkopf Dennis Purcell and his wife Judy had been remodeled, and they only Parsons (who has been president needed to add their own touch. of both the Ann Arbor Farm and Garden When the previous owners, from Dearborn, Club and the Master Gardeners of Washtbought the house, they realized it was an enaw County) found this house on the lake untouched portrait of the 1940s. They conby canoeing through numerous lakes to find a tacted someone at The Henry Ford, then

It ended up being used to furnish Barry Gordy’s apartment at Hitsville U.S.A. in Detroit. The kitchen appliances, the bathroom, and even the linoleum were used. continued on page 32

The husband and wife team of Dennis Purcell and Judy Parsons created and maintain their lakeside garden together.

What a wonderful view to have while working in the vegetable and rose gardens, situated between the house and the lakefront.

Many rock walls were built to hold back the earth and terrace the steep property. Judy and Dennis have taken advantage of this by planting flowering perennials and shrubs on these different levels.

Roses and dahlias The yard was a different storyâ&#x20AC;&#x201D;but the rock walls and the potential Judy and Dennis saw to make a beautiful garden made it the perfect place for them. The doctor that lived there in the 1940s had the rock walls constructed after he drove down the steep driveway in his new Cadillac and kept going right into the lake. That was not going to happen a second time, so he had the rock walls and the bomb shelter built. Now the walls form terraced hills that are home to countless beautiful shrubs and perennials. When Judy and Dennis moved here in 2012, they got to work on the garden. They installed a seawall and raised parts of the yard that were too low. Then they started building the gardens. They created many planting beds on the property, including rose and vegetable gardens. Judy has been raising roses for 50 years and she was excited to start growing them at their new home. They did fine the first year and then they started struggling. She thought it may be the maple tree roots, but realized the soil was too wet for the roses. While roses love lots of water, they also want good drainage to go with it. Meanwhile, Dennis had started a terraced veggie garden on the slope of the hill leading to the lake, and the plants there were doing well. The drainage was perfect, so Judy talked him into switching with her. Her roses moved to the perfectly drained vegetable beds and his veggies moved to the less drained area. It was a win-win situation and things are looking up for both the roses and the vegetables. The property was originally part of a gravel pit and thus was very rocky. This necessitated Judy and Dennis to amend the soil with rich topsoil. The roses were doing better, but Judy was still having some problems, so she contacted the American Rose Society. After much discussion and photo observation, they determined that the problem was cold weather combined with wetness. Those conditions, unique to the lake setting, caused not only powdery mildew but anthracnose. The moisture and large amounts of fog from the lake were adversely affecting the roses. Judy now treats her roses early in the spring with a fungicide to stop the problems before they begin. She likes to grow roses that have fragrance, one of her favorites being â&#x20AC;&#x2DC;Pope John Paul II.â&#x20AC;&#x2122; When Judy decides she would like to have some more roses, she uses a technique she

The dahlia bed in front of the shelter is equipped with stakes that stand ready as the dahlias get tall. It is better to place the stakes immediately upon planting the tubers to avoid impaling them if you were to put the stakes in later.

These hanging begonias are just a small part of Dennisâ&#x20AC;&#x2122; collection of tuberous begonias. He keeps them in their pots and overwinters them in the basement.

Above and below: Judy and Dennis grow over 70 varieties of dahlias.

These milk jugs are the nursery for Judyâ&#x20AC;&#x2122;s rose cuttings. The cuttings are inserted into the soil, covered with a bottomless milk jug, filled with water once a week, and at the end of the summer, she has baby roses.

discovered by watching Dan the Rosarian on the Internet. She takes cuttings and places them in the soil in the shade. She then covers the cuttings with a milk jug which has the bottom cut out. Every week, she fills the jug full of water. By the end of the summer, if it works, she has new small rose bushes. She gifts them to friends or plants them in her own garden. Another group of plants Judy and Dennis both love are dahlias. They have over 75 tubers, which they plant at the end of May or beginning of June, not starting them in the house as some people do. They have numerous beautiful varieties in all shapes and sizes. After the first frost in the fall, they dig them and place the tubers in plastic bags filled with vermiculite, storing them in the basement. They keep the storage area at approximately 50 degrees and place the bagged tubers on wire shelves for a bit of air circulation. Other plants that need to be stored inside for the winter are Dennis’ gorgeous collection of tuberous begonias. He simply leaves them in their hanging baskets and stores them along with the dahlias.

The gardens continue to evolve Dennis does have his own unique, native plant garden at the edge of the lake. He worked with the lake habitat and planted varieties that enjoy the moist soil. He has Culver’s root (Veronicastrum), swamp milkweed (Asclepias), monarda, iron weed (Vernonia), and so many more. The pollinators were swarming around the plants when I was there, including bees and countless butterflies. It is a wild, beautiful part of the garden. The unusual backdrop of this garden adds to its beauty. Even the steep hillside is planted with beautiful shrubs, including many hydrangeas and hibiscus varieties. It wasn’t easy to tame the hill, and Judy and Dennis admit they have much more to tackle in that part of the garden. It was covered with Asian bittersweet and poison ivy, but Judy has removed much of it by cutting and painting the stumps with weed killer. This area provides background scenery for the lower gardens. With much work and love from Judy and Dennis, this property is growing and evolving. They have certainly brought it a long way from the day six years ago they canoed by and fell in love with it.

The dahlia bed is filled with blooms in October.

Both dahlias and roses are grown in the terraced beds—they do well in similar environments.

One of the disadvantages of shearing boxwoods is that it makes moist, unventilated conditions—perfect for fungal diseases. Also, it can get so moist that aerial roots will take moisture out of the air and sprout from stems, as shown here.

To determine which stems to remove, pat your hand on top of the boxwood and select the stems that resist the most. These will be the stiffest and oldest.

continued from back cover We also noticed that un-thinned boxwoods made for moist, unventilated conditions—perfect for fungal diseases such as Volutella blight. We even saw aerial roots growing happily from stems taking moisture out of the air.

Give your boxwoods an annual checkup The pruning technique we recommend begins with cleaning out dead or diseased stems. This practice allows for an annual inspection for pathogens such as boxwood blight—a deadly disease recently discovered for the first time in Michigan. Tightly sheared boxwoods are beautiful, but thinned boxwoods are beauti-fuller. By allowing light to penetrate and air to move, buds can grow and fill the inside of the shrub, creating conditions for dense, beautifully healthy plants. There’s no need to give up your topiaries and geometric hedge shapes either—utilize a hybrid pruning/shearing method to similar effect. We’ll describe that technique below.

Before you begin pruning Timing is key. As with most evergreens and non-spring-flowering shrubs, make sure you perform this work in early spring. Heavy summer pruning will rob your boxwood of the effort it spent sending up fresh growth. Also, check your forecast for rain. Cuts made into boxwood are portals for pathogens when wet. Allow a few days for cuts to seal before overhead watering.

Reach down into the plant, and use sharp hand pruners or a saw to remove whole stems with branches, all from deep inside the shrub.

Before pruning.

After pruning. This boxwood hedge is airy and will rejuvenate itself with May growth.

Do the pruning Step 1: (optional) Shear your boxwood

If your preference is toward formal, tightly clipped boxwoods, go ahead and shear the outside of your shrub with hand or electric shears at the desired height and shape. This initial shearing will make it easier to select the stems to remove in the next step.

Step 2: Thin out one-third of the oldest branches

Find the stiffest stems by patting your hand on the top of the shrub and selecting the stems that resist the most. Let supple, younger ones remain. If the boxwood has been repeatedly sheared, your cuttings will show leaves only on the extreme ends of their branches. The stem will be naked. Reach down into the plant, and use sharp hand pruners or a saw to create a clean cut and remove whole stems with branches, all from deep into the shrub. Your first deep cuts will have you secondguessing the aggressiveness of this method. Have faith—by the end of your work, you’ll have a uniformly thinned boxwood.

Step 3: Cut branches back to the buds

Move further up to the remaining branches and find a bud, leaf, or notch between two stems and remove 1/3 of the stiffest stems. Fresh new growth will fill in from these cuts.

Step 4: Clip outer shoots for shape The pruning method will leave supple, new growth at the top.

Finally, go over the outside of your box-

wood again and clip any cowlicks that have popped up. Shake and tug at stems to fully loosen the boxwood. Give the wind no chance to dislodge hidden, twisted branches. You may also wish to lightly shear once more to achieve your final shape. All done! You now have a fresh, loose boxwood that can rejuvenate itself with May growth. Light shearing in summer after such an aggressive prune is permissible, but not required. References: Janet Macunovich and Steven Nikkila. “Boxwood pruning.” www.GardenAtoZ.com.

how-to

Prune your boxwoods

After using the pruning method on boxwoods, the removed plant material will be long branches, as opposed to many small leaf clippings that result from the shearing technique.

Making the case for pruning, not shearing, in early spring

ur crew was enjoying a pleasant afternoon shearing boxwood. We employed the conventional, efficient method of lightly clipping the shrubs in early June to maintain the tightest shape possible. Our head gardener’s ear plugs, headphones, and electric shears made him numb to the world outside the monolithic polygon of green boxwood he was shaping. When finished, we all bowed to the thing he had created—a green block of order in a wild, chaotic world. Preoccupied by trimming other topiar-

ies around the property, we didn’t notice the newly hired, but highly experienced, gardener that got loose elsewhere and turned a boxwood into Swiss cheese, removing large, branching stems from the base of each shrub. I was brought to my knees in an Neil and Ruth onrush of doubt. “What does Atzinger this mean? Why?” I asked. The gardener explained her case for deep pruning, rather than shearing boxwood. And thus, my boxwood conversion experience—I was a changed man. When we started our own gardening

business, we abandoned the practice of frequent, light shearing and opted for the annual thinning and pruning that contributes to healthier shrubs. Here’s why…

Disadvantages of shearing The conviction to change our technique was confirmed when we noticed the effect our semiannual shearings had on boxwoods we had tended for years. One April, we discovered that heavy snow had damaged a closely

sheared boxwood hedge located in a formal entrance. The practice of removing one-third of old branches would have prevented these boxwoods from becoming the leggy, hollowed facades of green that semi-annual shearing created. Boxwoods branch and become dense at the spot they are clipped, suffocating the inside from light and air. Annual, deep, spring pruning would have yielded green, leafing stems to work with inside the damaged boxwood. A rejuvenated hedge could have been re-shaped after just one flush of late spring growth. Instead, the only acceptable solution was to remove the entire hedge. continued on page 38
