From Where I Stand — Soooooo, what’s everyone been up to?

I ended my last column apocryphally saying that when I wrote my next column, the world would be different, we all would be. The night I banged that out on my keyboard, the President had declared a National Emergency, all flights were suspended from Europe, and to make matters worse, Tom Hanks was diagnosed with COVID-19. Two days later, schools across Illinois would be shuttered. The following Friday, the Governor would issue his first Stay-at-Home order. It’s hard to believe that was only 35 days ago. It feels like a lifetime. Days move so slowly in the COVID-19 universe, if you can even determine what day it is at all. The good news is that society didn’t descend into a post-apocalyptic horror show. Sure, the first weekend toilet paper became the coin of the realm and people bulk purchased as if their families were going to subsist on coffee and chili for the next three months. For the most part, people have been kind to one another. We have reached out to old friends. We have refrained from arguing about life’s trivialities. We have been inspired by acts of kindness and sacrifice. We have refocused on what is important, and it is not, what we used to think was important. We have spent time with our families and learned to love life’s simple pleasures again: reading a book, putting together a jigsaw puzzle, watching old movies, playing board games, and trying and failing to bake our own bread. We’ve stood on driveways and talked to neighbors. We’ve Zoomed with our families on holidays and birthdays. We’ve screamed at our kids’ E-learning assignments for not printing or formatting. We’ve always understood the value of doctors and nurses, but we never appreciated their courage. We’ve learned the value of grocery store clerks, Amazon pickers and packers, postmen, and pizza delivery guys. We learned the term essential businesses and it wasn’t the people with fancy degrees or big salaries. Essential businesses are the men and women who keep America working: the construction crews, the exterminators, the janitors, the IT guys, and, yes, the landscapers. I won’t lie to you, it was touch and go that very first weekend. Oak Park was actually the canary in the coal mine and issued a StayAt-Home order about five days before the State did. The community was well-intentioned and borrowed a page from the Bay Area, which led the country on sheltering in place. A term that used to be reserved for nuclear attacks and tornadoes would now just become, well, life. Board member Scott McAdam, a handful of Oak Park members, and I spent the evening after Oak Park’s announcement banging out a letter to the Mayor to make our case why landscape services should be considered essential during this time. That exercise proved prescient because the entire State of Illinois would issue an order on Friday, March 20, and it did not include the word landscaper anywhere in the document. The ILCA Board met the morning of Saturday, March 21, to discuss the language of the Executive Order. It seemed to open the door to landscape professionals working, but was not clear in any sense. The Board knew we didn’t have the authority or standing to issue something definitive. The Board, as all great Boards do, talked through the entire issue and created a path forward that had consen-

sus. We would ask the Governor for clarification of our interpretation that landscape professionals did fall under Section 12 of the Executive Order. I spent the entire Saturday and Sunday emailing back and forth with the Governor’s staff. On top of dealing with a statewide pandemic, procuring medical equipment that would save lives, they had to determine which businesses could work and make money and which would be shut down. Too often, in a hyper-partisan world, we forget the central role of government — protect the way of life of its citizens. I have been amazed at the state and local governmental officials from hundreds of villages and municipalities and dozens of governmental agencies. These public servants are saving lives and livelihoods and don’t get enough credit for the speed and efficiency of their work. Those in the Governor’s office were fair and they listened. They gave us a few fleeting moments of their time and they deemed landscape professionals essential. We truly were moved from one column to the other, and it saved spring in the landscape industry and maybe hundreds if not thousands of jobs and landscape companies. I can’t credit my counterparts at each of the state’s green industry associations enough. Kellie Schmidt of the IGIA and April Toney and Jake Miesbauer of the IAA were simply fantastic. We parsed out who was doing what, spoke almost every day, and used our resources and connections. This was not a time for association partisanship or territorial disputes. I was proud to call these people my friends and colleagues. Right before I hit “send” on my final email to the Governor’s office, the email that would offer my last, best case for why landscape services are essential, I took my dog for a walk to clear my head. It was late afternoon on Sunday. A light snow was falling. I ran across a tree care crew taking down a 40 foot tall, diseased maple. I snapped a picture. It was the last piece of evidence I included. I got a response from the senior policy director. She told me to sit tight and they’d have a decision in the morning. I woke the next morning at 4am. At 7am, the Department of Commerce and Economic Opportunity deemed landscape services as essential and our members were told to go to work and stay safe. At that moment, we entered phase two. Just how are you supposed to run a landscape businesses in the middle of a pandemic? ILCA staff met that Monday morning, as we do every Monday. We talked about throwing away the old model and brainstormed how we can deliver value to our members when they are battling the invisible enemies of COVID-19, fear, anxiety, and economic uncertainty. We figured the best way forward was to emulate the very governmental bodies we had come to trust and respect. Tell the truth, be transparent, help people wade through the clutter, and you know you are doing a good job when you have too many solutions for too few problems. We have used social media during this time to get information out to members quickly and efficiently. I had so many members tell me, “Well, I’m not much of a Facebook guy.” My response, “Well, become a Facebook guy.” We decided to issue a daily COVID-19 bulletin which, we expected to go down to a semi-weekly or weekly email. Yeah, that hasn’t happened. New information has to be

Essential Services

The Landscape Contractor May 2020

From Where I Stand — shared every day. I am longing for the day when I can say, “Hmm, no COVID news today!” I also decided to use Facebook Live just as other elected officials use press conferences. It’s not necessary, but it brings me calm. It’s usually the last thing I do each day and let’s me take a breath. I just miss that feeling of connection to our members and those Facebook Live segments are the closest I can get. The hard part is remembering to put on a clean shirt! The ILCA Board has been amazing giving us direction, providing resources, and trusting ILCA staff and our committees to make decisions on the fly. Their trust in our efforts have helped staff stay the course and pivot to turning ILCA from an event-driven organization to a member-services organization in one month. They pushed for better consumer resources to tell our story. They illuminated the HR and safety concerns their companies were wrestling as they attempted to get back to business when business was anything but usual. Yet, I most appreciated their caution and their ethics. The Board knew that ILCA was being asked to provide a leadership role for 5,000 landscape companies. People looked to us and we could not be reckless or craven. All on the Board and within the ILCA staff said we need to be able to look ourselves in the mirror when this is all over and we need to be able to hug and shake hands with as many of our industry friends as possible. We need to get information to our members to keep their team’s safe — physically, emotionally, and economically. With all that being said, I have been most impressed by our members. I’ve remarked before that landscape contractors have this bizarre quirk where they care, deeply, about their competitors. They care enough to share information, best practices, wisdom, and guidance. The ILCA is a reflection of that. My heart swells when I read the comments in the closed Facebook group or the emails people send. ILCA members are assuming the awesome responsibility of being safe, sanitary, and protecting the public’s health — a job no landscaper ever signed up for. Our members send their employees back to their families every night. Many change in the garage or shower the moment they walk in the door. We are blessed to be able to work, but we are far more blessed to have healthy loved ones and families during a time when not everyone is so lucky. I’ve received a lot of emails, texts, and phone calls thanking the ILCA for being a light during these dark times. I could say “It’s all in a day’s work.” That’s a lie. I never expected work to involve this. The reason ILCA is working so hard is because of all the people we care so deeply about in this industry. We will gather again. We will raise glasses and exchange handshakes. We will remember the crazy times of COVID-19 and the face masks and the toilet paper and the Zoom happy hours and the moment we realized that even during our darkest, scariest hour — we were never alone. Thank you members of the Illinois professional landscape community. Let’s take it one day, one week, one month, at a time. Regards,

President’s Message — Finally, the light at the end of the tunnel. Let’s hope there isn’t a train coming from the opposite direction! We are living through an unprecedent global crisis and our 22 trillion-dollar economy has dramatically slowed down due to the presence of COVID-19. The economic indications have shown alarming signs. To date nearly 17 million people who have filed for unemployment. The Federal government passed a law to support small businesses and taxpayers in record time, amounting to $2.3 trillion. Tremendous times call for tremendous measures. On the other hand, and fortuitously, landscape services and construction have been deemed ESSENTIAL to the economy and by executive orders we are given permission to continue projects. Taking precautionary measures is now the new norm. With the adversities that we face, we should be immensely thankful to the heroes in the healthcare, first-responder, and food industries who have been key to making life more manageable in this craziness. They minimize the public’s risks and show the best in humanity. Recognition is also due to our leaders for their support and guidance. Thank you to all. Last but not least: A lesson to take away from this global crisis is that our environment has benefitted from the lack of contaminants emitted these last weeks. Pollution is a serious cancer, and we have to change as a whole if we want an improved world for future generations. ILCA management will continue supporting and informing our membership as best we can. I ask you all to participate and promote the 2020 Census, it is very important and there is still time to do it. In addition, keep taking precautionary measures in your businesses, homes, and with yourselves. As I said before, “Mind the trains! Work diligently, confidently, and with lots of caution.”

Finalmente... ¡Luz al final del túnel..l ¡Esperamos no sea otro tren en sentido contrario!

Sucediò lo inesperado... estamos viviendo una crisis mundial sin precedente, nuestra economía de 22 trillones se desaceleró dramáticamente con el COVID-19 y los indicadores económicos mostraron señales alarmantes; a la fecha casi 17 millones de trabajadores acudieron a la oficina de desempleo, el gobierno federal aprobó una ley de apoyo a pequeñas empresas y contribuyentes en tiempo record, por $2.3 trillones de dólares. ¡A grandes males, grandes remedios! Por otro lado —y por fortuna, Paisajismo y Construcción fueron clasificados como esenciales para la economía y por orden ejecutiva tenemos luz verde para continuar activos. Con las respectivas precauciones que ahora son parte de una “Normalidad” nueva. De cualquier manera y aún con las adversidades que enfrentamos debemos agradecer a los héroes de la salud, el orden y alimentación que contribuyen a hacer más llevadera esta locura, aminorando riesgos para todos y mostrando lo mejor del ser humano. ¡Gracias a todos ellos! También a nuestros dirigentes por su apoyo y guía. Por último pero no menos importante: el aprendizaje a tomar de la naturaleza: Nuestro Medio Ambiente se vió beneficiado con más oxígeno y menos contaminación, o sea: tenemos que cambiar si queremos un mundo mejor para futuras generaciones. En la dirección de ILCA hacemos lo que está a nuestro alcance para seguir apoyando e informando a nuestros miembros. Les pido su participación y promoción en el Censo 2020, es muy importante para todos y aún hay tiempo para hacerlo. Además, seguir extremando precauciones en sus empresas, familias y con ustedes mismos. Y como dije antes, ¡Cuidado con el Tren..! Salgamos a trabajar con Optimismo, Fe, Confianza, Esperanza, Amor, Actitud, y Seguridad... ¡con mucha Precaución! Saludos cordiales,

Mariani Landscapes â&#x20AC;˘ Lake Bluff Mediterranean Retreat

The Art Deco past of this historic 1920s resi-

dence in Illinois was carefully revived. The landscape architect worked closely with the architect, interior designer and client on this restoration to add new spaces, details, materials and views. New French doors were added to improve the flow and encourage indoor-outdoor connections and views. Original clay-tile roofing was seamlessly restored, while architectural detailing was meticulously recreated, achieving aesthetic continuity between old and new. New stone and gravel terraces with clay-brick detailing blend seamlessly with the architecture. The landscape architect worked hard to create seasonal interest in the planting palette. The large lawn was enhanced by a border

of native and seasonal plants. Significant trees around the property â&#x20AC;&#x201D; including Cornelian cherry, American elm, sugar maple and white pine â&#x20AC;&#x201C; were preserved, while evergreens and Norway spruce were added for additional privacy. Drainage was a challenge on this project, as the home is just outside of a flood zone. The team had to think carefully about grading and set up an elaborate underground drainage system to make sure the lawn and landscape drain well. The client desired a casual, yet elegant, space for spending time with family and entertaining friends. A large patio, featuring an outdoor kitchen, dining area and plenty of seating, was created and a fire pit was included to extend the season. The end result is a beautiful space for family and friends to relax and enjoy.

(continued from page 10) trunk more readily. At least that’s what we think and what we have observed. It’s one of the areas where we need a lot more research,” observed Miesbauer. Ice is a different story. Tree branches aren’t necessarily actively moving. “Ice slowly accumulates on the branch, just like it does on power lines. We’ve looked at how much ice a branch can hold before it breaks. Some studies show it’s something like 30 times its own weight in ice. It seems like a very large amount, but trees can handle it,” reported Miesbauer. Snow acts differently. “That’s less the case with snow because it doesn’t adhere to itself very well. With snow loads, you just get that wet heavy snow. But again, similarly, if the wet heavy snow is clinging to branches, and wind blows, it’s kind of the dynamic loading on top of the static loading that leads to more damage.” With climate change driving increasingly extreme weather, trees have more challenges. We discussed some of the ways people can ensure that these valuable landscape plants have the best chance at surviving these events. As you and your clients assess their trees, when it comes to storms, large shade trees have the most forces acting upon them. “Wind speed increases as you get farther from the ground. The crowns of large trees are often above the roof line of buildings. If you think about a suburban neighborhood or a strip mall situation, large shade trees will be above a lot of those

structures acting as windbreaks. So you have stronger wind forces and the trees are more exposed when they are tall, mature shade trees. Oftentimes, smaller ornamental trees that don’t get particularly large at maturity are more sheltered. Trees like crabapple or redbud, that are smaller, are never going to experience those really strong forces because there’s just not enough tree there,” observed Miesbauer. “Think of a long branch as a really long lever arm. If you have a shorter branch, you have a smaller lever arm for those forces to act on. When I talk about catastrophic wind damage, I’m talking about large shade trees.” One of the biggest questions is pruning. Are there ways to prune trees to give them better structure to survive storm events? “I tell people first and foremost it’s best to always start when the trees are young,” recommends Miesbauer. “At planting, if we can get the tree off on the right foot it solves a lot of problems down the road. We can take care of any small structural defects when the tree is young and continue a proper structural pruning maintenance routine periodically as the tree moves from being newly planted through its growth cycle into maturity. By the time it reaches maturity, it should have a strong structure that makes it less susceptible to (continued on page 14)

Focus — Weathering the Weather with Trees (continued from page 14) because they had been slowly subordinated over time. When we cut that broken branch off, it wasn’t leaving that large of a pruning cut on the trunk. Proper pruning ahead of time, even when those branches do fail, it’s often not as catastrophic or as detrimental to the tree because it’s been trained with that in mind.” When trees experience catastrophic damage to large limbs, it’s significantly harder for a tree to respond. “When they try to seal a big wound, it’s very difficult and it takes a lot of resources that the tree would otherwise allocate elsewhere. It is also a place for infection and decay fungi to enter and large wounds on the tree often lead to large decay pockets,”

commented Miesbauer. Miesbauer recommends consulting an ISA-certified arborist if problems are spotted “If you do see structural defects such as cracking, especially along the trunk or in large branches, consult a certified arborist to inspect it further. Ask about any cavities, which people can be overly concerned about. As far as pruning mature trees, it’s recommended that pruning be done out at the edge of the canopy. Usually, just a small amount of crown area reduction can make a big difference.” Miesbauer had a last piece of advice: “Plant properly. A moderate amount of care as a tree is growing up will pay large dividends as that tree matures.”

Trees and Climate

A Conversation with Dr. Christine by Heather Prince

As we attempt to weather the fickle

winds of climate change, how do we strategize tree care and selection? We sat down with Christine Rollinson, PhD, Forest Ecologist at The Morton Arboretum to follow up on her inspiring presentation at iLandscape 2020 about climate change and trees. In the face of the challenge of uncertain climate patterns, what trees should we plant? “It’s probably the question we get asked the most,” commented Rollinson. “We don’t make specific recommendations for a variety of reasons. Trees live a long time, so most trees are adapted to deal with an incredible amount of climate variability. Plus, because it’s not the same pattern every year, it’s hard to say what’s going to do well or what’s going to do poorly. Climate is only one of many factors that should go into your plant choices. The fact that it’s going to get warmer, doesn’t override the fact that say, there’s a power line overhead, or you’re planting in an extremely shady spot. Those considerations don’t go away. The other thing is that now weather is highly unpredictable and it is going to become even more unpredictable in many ways.” Because of the vast array of unknowns, Rollinson recommends, “We really want a diversity of trees. If you want to know what to plant in your yard, look around at what you neighbors have and plant something different. The right tree to plant is something that will increase the diversity so that we spread out the risk. Like your financial portfolio, you don’t want to put all your eggs into the dot. com basket from the 90s because eventually any boom will bust. So, we want to spread that risk around.”

A remarkable tolerance, but

The 2018-2019 winter saw intense cold and that damaged some trees, but not all. Because they can’t go anywhere and have potentially extremely long lifespans, most trees can survive an extreme event. “Most trees can handle getting hit once or twice, maybe one or two years in a row, maybe a bit more. But, as long as weather continues to be hot one year, cold the next, if we have many different trees, it’s highly 18

unlikely that the same tree is going to be hit all the time and in everybody’s yard. It’s not just climate. The big question mark is what is going to happen to our trees in the future is the pest and pathogens part. That is probably the most unpredictable thing right now. We know trees can deal with a lot of weather stress, but it’s when we get the emerald ash borer, Dutch elm disease, gypsy moth, and all these species-specific pests moving in. Many of which are expanding their range because overall, winters are getting warmer. It goes back to that diversity. There are all these complex interactions that make us very hesitant to recommend a particular tree,” commented Rollinson. As you work with clients on tree choices, Rollinson observed, “I think one thing we can do is to help people to understand why they like a particular tree. Do they like the Autumn Blaze maple because of the great fall color? That helps us direct it and say if you want something about that size with great fall color, let’s look at an alternative. What do you love about your winged euonymus? You like its size and color? How about we look at sumac instead, which also has a great color. I think if we can get people to think about what they like about a plant, we can do some gentle course corrections.”

Post planting attention

Once you’ve got a tree different from the neighbors’ selected and planted, what’s next? How do we care for existing trees in the landscape? If storms are becoming more extreme, how do we prevent storm damage? The answer is proper pruning. “Pruning is critical because most trees evolved around other trees, in competition. They had to grow straight and tall to try and get light. When we take trees out of that highly competitive context, because there’s no brain in the tree telling it ‘you want to grow up, so you are nice and strong,’ when you grow it out in the open, most of these trees are like ‘oh, there’s light everywhere, I’m going to go get all that wonderful light.’ This tendency ends up making the tree really structurally vulnerable,” observed Rollinson. Because

the leaves can access light at every angle, branch growth follows. In some trees, like elms for example, you’ll find robust growth in all directions because there isn’t any light competition to limit it. Plus, a tree in an open landscape may have plenty of water and nutrients, so it can put on exponential growth without consequence. As caretakers, it’s vitally important to encourage strong structure in trees when young. “When you think about holding buckets of water, it’s a lot easier on your spine, if you’re holding them right above your head. Consider the people who carry heavy loads on their head, it’s all centralized. If you think about carrying those same buckets out on the side, it’s a lot of extra stress and your muscles aren’t really set up for it. And so, pruning is important so that we get that load bearing in a structurally sound manner,” agreed Rollinson. Timing is key. “You can’t wait until the tree is mature because it’s really a bit too late. Trees in a single year don’t put on a big branch, they add tissue little by little. What we want to do is make gradual course corrections to that tree over time. If you wait too long, then we can end up topping the tree where it’s cut back hard at the top. Topping is bad because it creates a weird growth form, it’s not structurally sound, and you’re removing a lot of twigs that support leaves and photosynthesis generation. When we prune a young tree, we’re taking off just a little bit of the branches to help promote that central leader. If we do that early, it’s small little course corrections, as opposed to having to amputate a whole limb.” How you prune is also important. “It’s not just pruning for overall form, but making those actual pruning cuts well, so that when the tree does start branching back again, it’s a healthy juncture and will help overcome any initial vulnerability. It’s making those cuts right, so they heal quickly, and we don’t end up with lots of weird right angles in those healing joints. Kind of like you want to make sure your bone is set properly after you break it, you want make sure it’s a good cut that’s going to heal properly and have a nice strong juncture.” (continued on page 20) The Landscape Contractor May 2020

(continued from page 19) In the midst of the barrage of advice, it can be challenging for clients to discern what is really necessary. We asked Rollinson what she felt was the most important thing people can do for their trees. “My answer is pay attention to them. Be aware what’s going on, but don’t freak out the first time a leaf changes color. When it starts to become a trend, or starts to become widespread, when we’re paying attention to it, then we can realize what’s going on. It’s kind of like knowing when to go the doctor. You don’t call the doctor every time you have a headache. You call a doctor when you have a headache for a month and nothing you do makes it go away.” This becomes especially important with pests and diseases. “Will you catch it before it becomes too late? By paying attention, you know what’s normal for your tree and trees in your area. By understanding what’s happening with your tree and around it, it will help determine what might be wrong with it. If your tree is the one sad tree on the block, we’ll start looking for unique stressors. Did it get hit with a string trimmer? Did you do some construction, and now water is pooling around the base? The goal is to try and not overreact but notice things when it’s still early enough to act.” One of the key factors to pay attention to with trees is water. A newly planted tree has different water needs than a mature one. Drought stress has been shown to affect tree health for years after the event. “When it goes from super saturated to overly dry, plants don’t go back to holding water the same way. It really requires kind of gentle watering, especially when it’s dry. The

The Landscape Contractor May 2020

— soil particles are stuck together and if you don’t water gently, the water is going to just run off instead of being absorbed into the ground. In many instances, it’s not the amount of water applied, it’s the pattern of water. In big storms and deluges, there’s a reason our streets flood. It’s all coming down too quickly and the ground can’t absorb it. If we’re experiencing drought, make sure to gradually apply water and get the soil back to that point where it can hold that water,” commented Rollinson. As we navigate the challenges of climate change and shifting weather patterns, there are opportunities to work with clients. “Think ahead is always the most important thing. Think for the long term and try to get your client to think for the long term as well. From a business perspective, it’s about developing lasting relationships with your client. You don’t dig a whole, stick the tree in, and let it go. It’s a living being. You don’t buy the dog, give it a big bag of dog food and say ‘OK, you’re good.

Check on you next year.’ It’s this kind of constant relationship between the tree, the owner, and the arborist or landscaper. It’s right tree, right place, as well as that long-term maintenance monitoring. Random things happen, but if we can catch it early, we can help improve that tree. There’s usually much more we can do before it gets to ‘Oh, my tree didn’t leaf out the past two years, can you save it?’. If we can catch it before that point, then everyone wins.” As you’re navigating our new normal with your team and clients, remember that trees are resilient. If we can start the care and monitoring process with planting, both the tree and the owner will reap great benefits. “We’re not asking people to do things fundamentally different, we’re just providing a new perspective that they can use to help frame what they do and how to build or enhance their services,” remarked Rollinson.

Magnificent Magnolias Revisiting an Heirloom Favorite

by Heather Prince

A classic herald of spring, magnolias are

a romantic heirloom favorite tree for many of us. We talked to Matt Lobdell, Curator of Living Collections at The Morton Arboretum and vice-president of the Magnolia Society International about how to grow magnolias and cultivars that thrive in the Midwest. An ancient plant that pre-dates the evolution of bees, magnolias are easy-going trees in general. Their large showy flowers with stiff leathery tepals are believed to have been pollinated by beetles. The ideal site for most magnolias is well-drained with slightly acidic soils, but they are exceptionally adaptable and include some wet-tolerant species. They flower best in full sun, but will tolerate light shade. Magnolias, like most trees, will exhibit more pests and diseases when they are stressed, but are low maintenance for the most part. Magnolia scale is prevalent in our area, but

treatable, especially if caught early. “After flowering, prune for crossing branches, but they don’t need too much. Most magnolias tend to be grafted, so you want to be careful of the graft union. Understock takeover can be common, especially with the rare ones,” recommended Lobdell. “Make sure you have an understanding of the mature size of the plant. We see this with the yellows. They’re great, but they can get very very large and some of them don’t have the neatest habit as they get older. Make sure it has ample space. Magnolias don’t do a whole lot after May, so maybe not make it the dominant tree in the landscape. Make sure your clients have realistic expectations of the flowering period.” One of the biggest challenges in magnolia cultivation in the Midwest has been enjoying their spectacular flower show without the newly opened buds or blossoms freezing in (continued on page 26)

Spring 2020 — (continued from page 22) our fickle late spring weather. Breeders have been developing later blooming varieties and ones with larger flowers to maximize their showiest feature. “To have successful spring blooming magnolias in this region, you want to get them flowering as late as possible because that tends to avoid the spring frost risk. Magnolia × soulangeana tends to get hit the hardest because it starts flowering in late April when we get cold nights and have late frosts,” commented Lobdell. There are two species native to the U.S. that exhibit some unique characteristics we don’t normally associate with magnolia. Magnolia virginiana or sweet bay magnolia thrives in part shade with moist to wet soils and has fragrant white flowers in June. It needs a protected spot to survive zone 5 winters and is often multi-stemmed. Magnolia acuminata or cucumber tree is a large tree, sometimes reaching 70 feet, and featuring greenish-yellow flowers. Plant breeders have been developing crosses and cultivars with it to develop selections with yellow flowers and later blooming habits. Other species and crosses that are commonly available are Magnolia x soulangeana or saucer magnolia. This is the traditional favorite with pink and white tepals. Magnolia stellata or star magnolia blooms first with thin, strappy white or light pink tepals that resemble a powder puff or star. Magnolia x loebneri is another early spring bloomer that can be white or pink that gets larger than star magnolias. Despite their commonness in the Midwestern landscape, magnolias worldwide are a plant of concern. “Roughly half of the species of magnolia worldwide are in danger. Even if they are common landscape plants, they are a species of concern, especially the tropical ones. In some cases, they are becoming threatened or going extinct as soon as they are discovered,” cautioned Lobdell. “I highly recommend the trees overall, even in the light of climate change. A lot of them have a good range of hardiness, and they do seem pretty adaptable, so they have a place in the landscape moving forward.” Although there are more than 1,000 recognized cultivars of magnolia, Lobdell suggested some favorites that are readily available.

Magnolia × soulangeana ‘Alexandrina’

Height: 20 to 30 feet Width: 20 to 30 feet Habit: large, loosely pyramidal, multi-stemmed tree Flower color and habit: Large medium pink flowers with white interiors in the classic cup-like shape. Flower timing: April, about two weeks later than straight M. x soulangeana

Notes: “Alexandrina is a good one. There are at least two forms you can find in the U.S. The more common one is a pyramidal form with a paler flower and you can see one right outside the Visitor Center at The Morton Arboretum. There’s also a dark form that’s more rare and that’s what Europeans think of when you say ‘Alexandrina’. The M. x soulangeanas are still probably one of the best selections and it’s hard to find anything that’s more floriferous,” recommended Lobdell. The hybrid was named after Étienne Soulange-Bodin, the Director of the French Royal Institute, who made the cross in the early 1800s after retiring from his diplomatic career under Napoleon.

Magnolia ‘Galaxy’

Height: 20 to 25 feet Width: 12 to 15 feet Flower color and habit: Large rose pink to purplish with white interior in a saucer shape Flower timing: late April Notes: ‘Galaxy’ is a hybrid magnolia cross “from the U.S. National Arboretum breeding program that was introduced in 1980,” commented Lobdell. It has a more upright, pyramidal habit and may get a coppery bronze fall color. It’s a good choice for clients who seek a classic saucer magnolia, but with a tighter shape for a smaller property.

The Landscape Contractor May 2020

Little Girl series of magnolia Height: 8 to 10 feet up to 15 feet Width: 8 to 10 feet Flower color and habit: shades of rose to deep purplish-pink Flower timing: mid to late April with occasional summer rebloom Notes: The Little Girl series includes named cultivars, ‘Ann’, ‘Betty’, ‘Jane’, ‘Judy’, ‘Pinkie’, ‘Randy’, ‘Ricki’ and ‘Susan’. They are shrubby in their habit and densely twigged. “The magnolias in this series are all very hardy. The goal was smaller, more landscape size, and later flowering trees. I like ‘Ann’ a little bit more because of the darker flowers and fewer tepals. ‘Betty’ gets bigger with paler and floppier tepals. Of all of them, ‘Betty’ and ‘Ann’ stand out the most, for me. They’re nice plants if you have a smaller area and late flowering, so they tend to be after the frosts,” recommended Lobdell. (continued from page 26)

(continued from page 25) Magnolia ‘Elizabeth’ and ‘Yellow Bird’ Height: 30 to 40 feet up to 50 feet Width: 20 to 25 feet Flower color and habit: ‘Elizabeth’ features pale butter yellow flowers; ‘Yellow Bird’ has mid-yellow blossoms Flower timing: mid to late April Notes: The yellow magnolias have been developed from crosses with M. acuminata, which tends to make them fastgrowing and large in scale. “With ‘Elizabeth’ you get large, creamy yellow flowers, but it grows really large. I also like ‘Yellow Bird’ that we have in the Groundcover Garden. It flowers after it leafs out and has nice bright yellow blossoms,” reported Lobdell.

Magnolia ‘Elizabeth’

The Landscape Contractor May 2020

Magnolia ‘Butterflies’ and ‘Sunsation’ Height: 18 to 20 feet up to 30 feet Width: 15 to 20 feet Flower color and habit: ‘Butterflies’ features upright yellow flowers that resist fading. ‘Sunsation’ has large creamy yellow flowers with a blush of pink at the base. Flower timing: late April into May Notes: Both of these yellow blooming magnolias are smaller in scale than others and bloom much later, often in May. ‘Butterflies’ tends to be upright and pyramidal. Both are usually found singlestemmed. “Sunsation is a hybrid for hardier flowers that bloomed later and it gives you get a daybreak effect where you have a mix of pink or peach and yellow,” observed Lobdell. (continued on page 28)

Magnolia ‘Sunsation’

Magnolia ‘Yellow Bird’ The Landscape Contractor May 2020

Spring 2020 — (continued from page 27) Magnolia x loebneri ‘Leonard Messel’ and ‘Merrill’ Height: 25 to 30 feet Width: 20 to 25 feet Flower color and habit: Narrow, strappy tepals give a pom-pom effect. ‘Leonard Messel’ features purple buds that open into pink tepals with white interiors. ‘Merrill’ blooms pure white. Flower timing: early to mid-April Notes: The Loebner magnolias were hybrids developed by German horticulturist Max Loebner in the early 1900s. These are multi-stemmed trees that can be fast growing in the right site. The flowers are pleasantly fragrant and abundant. “’Leonard Messel’ is a nice one. It doesn’t get too big and it’s very durable and pretty. It’s one of the better pink ones,” commented Lobdell.

Magnolia ‘Merrill’

Magnolia virginiana ‘Glauca’ and ‘Jim Wilson’ or Moonglow® Height: 10 to 20 feet Width: 10 to 20 feet Flower color and habit: Globe-shaped lemon-scented white flowers often tucked into foliage. Flower timing: late May into June Notes: One of the few magnolias that tolerate shade and moist to swampy soils. You’ll find them as multi-stemmed specimens that have an oval to rounded habit. ‘Glauca’ leaves have brighter white undersides. Moonglow® was developed to be hardier for northern climates with more evergreen foliage and larger flowers.

ILCA Honors —

A Winnetka Retreat

by Heather Prince

When the property behind them became avail-

able, this Winnetka couple took the opportunity to upgrade their residence and create a private retreat. The winner of the Contractor’s Choice Award at iLandscape 2020, this French Provincial home’s romantic formal landscape was designed and built by Chalet, a North Shore company with over 100 years in service. It has truly become a lush respite and lovely entertaining space. Purchased in 2015, the stately home already featured a sweeping entry drive, but the backyard was a vast expanse of lawn with only a thriving Techny arborvitae hedge bordering it. Already longstanding clients of Chalet, the clients worked with Nate Robinson, RLA, Chalet’s Creative Director and Landscape Architect to transform and connect the two properties over the course of about five months. A graduate of the University of Illinois’ landscape architecture program,

Robinson joined Chalet in 2003 and has been immersing himself in the North Shore communities and landscape demands unique to the area. He relishes working with clients to fit the needs of each family while creating unique spaces with stunning visual impact. “After purchasing the new home, the clients quickly realized that their previous house would make an ideal guest house, but they needed a comprehensive plant to connect the two,” observed Robinson. The property was a blank canvas, and “the rear elevation had small bluestone patios at each entryway that didn’t connect and were at different levels. The stoops and steps were failing. It was very disjointed. The clients wanted a way to move seamlessly around an entertaining space that could accommodate large parties or intimate gatherings. We unified the area with sweeping bluestone terraces anchored by large beds in scale to the home. They love to grill and eat outdoors,” reported Robinson. “We

The Landscape Contractor May 2020

designed it to be a very flexible space so people can gather together or break away into small groups, whatever the occasion.” The seat walls framing the bluestone patio areas were clad in whitewashed clay bricks and capped in limestone coping to mimic the stone of the home. “We installed smart lighting and audio speakers in the walls as well as added these elements throughout the planting areas. It’s all controlled by an app on the owners’ phone, so they can set the mood with the tap of a finger.” The established healthy arborvitae hedge provided privacy, but it also disconnected the two properties. Robinson and his team at Chalet were up to the challenge. “We brought in a tree spade and transplanted a whole section of 12-foot tall arborvitae to open the view between the two homes. I’m very proud that we managed to relocate each tree successfully, nursed them through the transplant shock, and they are thriving,” commented Robinson. As the team worked to rehabilitate the patchy and failing rear lawn, they discovered their biggest challenge. When the home was built, the builder had used the back yard as a staging area. “We found all kinds of construction debris from pieces of plywood, chunks of concrete, asphalt, bricks, pieces of stone. It was also so compacted that the clay soil was like concrete,” Robinson remembered. “We elected to strip it

away and replace it fresh topsoil down to between 10 and 12 inches. It ended up being 200 cubic yards of soil. This had the added benefit of improving the drainage significantly.” Although they didn’t experience major drainage issues, Robinson chose to ensure any water moved appropriately through the property. When they renovated the lawn, they also added French drains to ease any stormwater issues. “The whole yard pitches north to south. We ensured that the drain tiles moved water into a bioswale that connects the rear of the property to the front. Stormwater flows into the bioswale where it gets filtered before moving into the stormwater system at the street,” indicated Robinson. The sprawling terrace is elevated and “we plumbed the terrace as well and included drain tile underneath, so any water is directed into the bioswale system.” As you step out onto the terrace, you have several choices of comfortable seating among the groupings of wrought iron patio furnishings. Fresh flowers tumble from planters and containers dotted throughout the space. The clients beloved dogs may greet you. “The plantings had to be very dogfriendly,” commented Robinson. “Their dogs are like family. We included a small drinking fountain, so they always have fresh water. There’s also an outdoor washing station for (continued on page 32)

Black urns add subtle focal points and an open wrought iron fence and gate connect the two properties but also keep the dogs in bounds. Shaded by two maple trees, dual beds curve away from the shallow steps leading you from the terrace into the lawn. The beds are filled with Poukhanense azalea for a riot of hot pink blossoms in spring and mahogany fall color. Offset with Everlow yew for winter interest, Robinson used large swathes of long blooming perennials for low-maintenance color. “The clients didn’t want roses in the back yard because of the dogs. They also shied away from strong colors like reds and yellows. We used a lot of pastels

to keep a serene, romantic feeling. The goal was a beautiful restful space loaded with flowers but pet-friendly,” commented Robinson. A curvaceous bluestone path leads you off the terrace and around the lawn, outlining the lush plantings that connect the two properties. Formal trimmed boxwood provides a backdrop to billowy amsonia, upright feather reed grass, garden phlox, allium ‘Summer Beauty’ and the bold summer color of hydrangea. Limelight and Quickfire hydrangeas provide abundant summer flowers in the sunny edges, while classic Annabelles light up the shade. The creamy bark of clumps of river birch is picked out against the dark backdrop of the Techny arborvitae hedges and adds a crisp note in winter as well as softening and anchoring the curving walkway.

A pair of columnar spruce provide winter interest and screen from the larger entertaining space. A froth of hydrangea offers a romantic summer view. While Robinson’s design primarily focused on the backyard retreat, the front elevation also needed attention. A new heated walkway ensured easy snow removal in winter months and enhanced the existing drive. A pair of black urns frame the front door. “The owners wanted to enhance their privacy but also provide perennial color,” indicated Robinson. The team installed a boxwood hedge for evergreen screening from the busy street. In between the hedge and the road, a welcoming new perennial bed was created. “We wanted plants that were hardy, salt tolerant, low

maintenance and offered nonstop color.” Splashes of salvia ‘May Night’, ‘Blue Hill’ and ‘Wesuwe’ punctuate the softer shades of geranium and calamint. ‘Pixie Meadowbright’ coneflower attract pollinators and people with their bright pink flowers from summer through fall. The strappy shiny foliage of allium ‘Summer Beauty’ is woven through and their powder pink flowers enjoyed for weeks. The clients are delighted with their new outdoor living spaces. “It really came together, and we’ve worked hard to establish the plants, so they have instant gratification,” said Robinson. “It was really rewarding to be able to incorporate these rich plantings in a scale appropriate to the formal residence.”

Qué cantidad de agua y a qué profundidad está disponible al suelo y las raíces es un factor del tipo de suelo, así como el microclima en el cual se encuentran las plantas. La tensión de humedad del suelo es la cantidad de succión que se necesita para mover el agua por el suelo, distribuirla uniformemente y ponerla a disposición de las plantas. “Hay buena tensión de suelo cuando los equilibrios de aireagua-suelo se mantienen y monitorean adecuadamente” dice. La capacidad de campo es la cantidad de agua que el suelo retiene después de que cualquier exceso se haya escurrido y la percolación hacia abajo se haya detenido. “Encuentro que la mejor y más alta tensión de suelo ocurre cuando se mantienen los suelos con su contenido de humedad en el extremo más bajo de la capacidad de campo, pero no al punto de marchitamiento”, continúa Cammarata. Si el suelo está en el extremo más alto de la capacidad de campo, no puede aceptar más agua porque se está acercando a los niveles de saturación, en otras palabras, el espacio de aire se ha agotado. “No hay niveles de oxígeno beneficiosos ahí para ayudar a los elementos biológicos a hacer su trabajo”, asegura Cammarata. Los contratistas de irrigación y paisajismo deben tener esto en cuenta al diseñar un sistema de irrigación. “Diseñar con detectores de humedad fijados para medir los niveles reales de aire y agua en el suelo, para que los sistemas

Special Series — Small Space Makeover

A Mid-Century Modern Makeover by Nina A. Koziol

The Project: Create a relaxing oasis of mostly native plants to match the architecture of a midcentury modern ranch house. The family has had the property since 1952. Family members from around the Midwest visit several times a year, often converge at for their traditional Swedish Christmas party. The clients wanted more outdoor space, with vegetables, a cherry tree, and drainage solutions and a turf-free rear yard with a new patio.

The Site: A 1,340 square-foot wedge-shaped corner lot in a well-canopied subdivision in Highland Park. A remnant creek bordered the property. Water issues resulted in crawlspace flooding and ‘yard pools.’ Privacy from corner street intersection was also a priority.

In our ongoing series on small space land-

scape makeovers, we look at a mid-century ranch house with a landscape in desperate need of curb appeal and usable space. Knockdowns. You can’t miss them in cities and suburbs. Small houses built after World War II replaced by towering McMansions that were made to look like French country houses or Italian villas, crammed onto narrow lots. “People are buying property and knocking down these smaller houses,” says landscape architect Deirdre Toner of D.T. Design, LLC, in Old Mill Creek, Illinois. However, not every one wants or can afford an enormous house. And, some houses are simply too special to the owners to sell and move on. 42

The Challenge: Open up the space; create a shade-tolerant, native ground cover mix; eliminate invasive celandine poppy creeping in from neighboring yards, and create a new drainage system. The client requested existing native plant collection blend into the new design.

The Inspiration: With several artists in the family, a patriarchal painting of a Swedish ‘Don Quixote‘ on the garage door was a neighborhood treasure. The family had renovated the home’s interior with stylish midcentury furniture and decorative objects in keeping with their father’s color palette of earthy jewel tones.

One of Toner’s projects was just that—a mid-century modern ranch house built in 1952 in Highland Park’s Sherwood Forest subdivision and owned by the descendants ever since. “It’s a corner lot on two nice streets in a soughtafter area,” Toner explains. “There are lots of old oaks and elms in the neighborhood and it’s a lovely home. Millennials love the area and the land value is good.”

Melding the House and Garden

The home’s interior holds the family’s collection of midcentury modern furniture. Toner’s goal was an updated landscape that would respect the home’s architecture and address (continued on page 44)

Special Series — Small Space Makeover (continued from page 42) the client’s needs and desires. Tempering a modern or contemporary architectural style for the landscape is a wonderful challenge. “You can’t put an Englishstyle garden in a mid-century modern landscape,” Toner said. But long before she developed any plant list or thought about hardscape, Toner looked at the original 1956 plat of survey and measured the entire site. “After 60 years, a lot had changed on the property and doing a base map was a challenge.”

Rain, Rain, Go Away

One of Toner’s biggest concerns was water on the property—a new drainage system was critical. An existing drain tile was relocated to a corner where the remnant creek previously ran, and now provides direct access to the city storm sewer. “The crisp angles planned for the new patio provided a balance of where the impervious space is located and

there’s been no flooding since the new drainage system was installed,” Toner said. “It’s not only how much impervious space, but also where it’s located on site.” Toner took advantage of overall site conditions and request for native perennials by including moisture-loving plants like birch, Carolina sweet shrub, Indian pink, monarda, columbine, oak and palm sedge grasses, Epimedium varieties, and a collection of native ferns. American hornbeam, Queen of the Prairie, cardinal flower, bowman’s root, beardtongue and a Joe Pye weed round out the sunnier selections.

New Approach

Two front doors each had a walkway—one from the driveway and one from the main sidewalk. After 60-plus years, the concrete walks needed updating. Toner designed a larger contemporary walkway from the drive to the front

entry and flanked it with ‘Fargo’ pinnacle white birches (Betula platyphyla ‘Fargo’). “I used the upright birch trees to create a rhythm that flows and draws your eyes across the property. The birch trees created an allée of privacy.” The new walkway from the driveway offers a generous landing space at the main front door. Toner removed the secondary walk, and steppers threaded through the garden beds lead to the new terrace areas. “Seeking a lower-maintenance hardscape product than traditional bluestone, which requires annual power-washing on most shady sites, we used a bluestone lookalike from Unilock called ‘Rivenstone,’” Toner said. She estimated the cement paver product cost about 40 percent less than natural bluestone.

Toner transplanted the Japanese maples as well as a climbing hydrangea and hostas, replaced the junipers and added drifts of perennials, grasses and woodies that offer multi-season interest. Arctic blue willows, Blackhawk big bluestem, tufted hair grass, Gillenia ‘Pink Profusion,’ Autumn Bride coral bells, mugo pine, September Charm windflower, purple moor grass, and Emerald Blue creeping phlox are some of the plants used in the project.

coneflower cultivars. “It’s a privacy screen,” Toner said. “All the passersby ask about the plants.” Because the property is viewed from two streets, the client wanted privacy for a second seating area and Toner obliged by designing custom panels that enclose part of the new patio. “I did historical

Toner added a privacy screen of smooth cedar, based on mid-century modern designs. The Landscape Contractor May 2020

Toner replaced everything in the backyard including a dated walkway and spotty turf and installed a large contemporary patio and sweeping planting beds with natives, native cultivars and low-maintenance ground covers. “I created a shady mix of natives with two types of carex, heuchera, and short goldenrod (Soldiago flexicaulis). There are pockets with ferns, and a side bed of Japanese forest grass with a beautiful Japanese maple and hellebores.”

A linden tree shades a large part of the rear garden. “There’s an epimedium garden—it’s such a good ground cover when you can’t get anything to grow in the shade.” Although the wedge-shaped property created some constraints, the back garden now offers the homeowners a peaceful, private Zen-like space in which to relax. “We created quite a bit of space there for entertaining,” Toner said. A small triangular vegetable garden was placed in the side yard. “It’s perfect for what the homeowner wants—it’s not overwhelming. She likes zinnias, too, and can sow them for cut flowers in late summer “There’s a whole layer of spring flowers—azaleas and phlox in the front garden offer a pop of spring color,” Toner said. “Other things flower in June and July and in August there are asters, coreopsis, and the smooth hydrangea nativar, ‘Invincible Spirit II,’ which has done very well.”

New Vibe

The landscape makeover resulted in a contemporary look that suits the onestory house. “Blending the landscape with the architectural style of the home is so important,” Toner said. “The fact that the family had maintained ownership of the property—and sought my creativity and ability to deliver the total project—was rewarding exciting,” Toner said. The renovation was done in two phases, with the front installed in the fall of 2017 and the rear in 2018. “I feel so much gratitude because they are so happy with the project.” The Team: Deirdre Toner, D.T.

Irrigation Update — Spring 2020

Irrigation Know How — Knowing How Not to Use an Irrigation System Understanding the Plant, Soil Water Continuum by Meta Levin

The key to effective irriga-

tion, is understanding the plant – soil – water continuum. If attendees at the iLandscape irrigation workshop: “Irrigation Know How – Knowing How Not to Use an Irrigation System,” walked away with nothing else, Larry Cammarata, principal and founder of Certified Consultants, wants them to commit that to memory. “Our industry must realize that soil is the lifeblood of the landscape,” he says, pointing to the importance of proper plant selection, the correct soil for those plants, the right amount of sunlight exposure and the right amount of water. It is crucial for landscape architects and designers to consider the soil type, sunlight exposure and irrigation – i.e. the plant-soil-water continuum – when deciding which plants to put in the ground and where. “Everyone must understand water and how it intersects with plants and soils,” says Cammarata, who has more than 41 years of experience in landscape design, management and installation, as well as agriculturally based water management systems. For instance, he points to a consulting job he did in southern Indiana. He was hired to look at the soil biology, but when he arrived, he saw that while the

landscape area was 80 percent shade, the plants all required full sun. The irrigation system just threw water over all of it. “I told the property owner that when he redeveloped the landscape, to let me work with the irrigation contractor for best product placement and development for this site,” he says. “Whenever there is a landscape modification, there has to be an irrigation modification.” When designing a landscape, it is important that the landscape architect or designers take the soil type into account, as well as the microclimate, sunlight exposures, plants and water needs. “You have to design it so that it all fits together,” he says. Here’s how it works. When soil is irrigated through an irrigation system, the water tends to stay on top of the soil, because the sprinklers usually deliver water faster than the soil can receive it. When rain falls, however, the water percolates faster down to one degree or another into the soil. Therefore, the rainfall tends to end up down where the root system can take advantage of it. “Irrigation is not the savior of the land-

scape,” he says. “More is not better.” Irrigation is, however, a tool in horticulture water management, “when properly used in the plant-soil-water continuum.” Irrigation systems are strictly to replenish the soil profile with water that has been lost through evaporation and transpiration, but which has not been replenished through rainfall. A healthy soil environment is 25 percent air, 25 percent water and 50 percent soil, minerals and nutrients. “Everything beneficial breathes oxygen and everything that doesn’t is nonaerobic and not beneficial,” says Cammarata. How deep and how much water is available to the soil and the plant root systems is a factor of the type of soil, as well as the microclimate in which the plants are located. Soil moisture tension is the amount of suction needed to move water through the soil, distribute it evenly and make it available to the plants. “Good soil tension occurs when the air-water-soil balances are properly maintained and monitored,” he says. Field capacity is the amount of water the soil holds after any excess has drained away and percolation down has stopped. “I find the highest and best soil (continued on page50)

Irrigation Update — Spring 2020 (continued from page 48) tension occurs when the soils are maintained with their moisture content at the lower end of the field capacity, but not at the wilting point,” says Cammarata. If soil is at the higher end of field capacity, it cannot accept more water, because it is nearing saturation levels, i.e. the air space is depleted. “There are no beneficial oxygen levels there to help the biological elements do their work,” says Cammarata. Irrigation and landscape contractors must take this into consideration when designing an irrigation system. “Design with moisture sensors set to measure the actual air and water levels in the soil, so that the system turns on only when needed,” he says. “This has proven to be a great tool for keeping the soilplant-water continuum well balanced.” Every landscape and irrigation contractor should know the soil. “Only supply water when it is needed.” And that also means taking the microclimates into account. These can vary from area to area on each property, containing or releasing moisture content in variable ways on the same site. They are important and affect the amount of water needed on any landscape. Again, Cammarata points to the

landscape on which he consulted in southern Indiana, much of which was on the east side of the building. “By noon, it had no sun,” he says. On the other hand, there are berms on many properties on which the top has full sun all day, while other parts do not. Some parking lot islands have full sun, as well as sunlight reflection off cars and car windows, not to mention salt damage from the snow season. If you have a glass building, the whole west side will have sun that reflects off the glass onto the plants and soil. “The reflection can cause a 30 to 40 degree difference in temperature from other parts of the landscape, thus increasing the water demand differently than other exposures on the same site,” Cammarata says. Or take the case of a reflecting pool on the property. The water may stay warm all winter, warming the land on the shoreline, winter and summer. This affects the irrigation needs. “The soil around it never goes dormant in the winter and never freezes,” he says. Irrigation along the edges of sidewalks, for instance, should be on different zones than other turf areas. Areas that get a lot of salt during winter have different soil structures, because of that

salt, than areas that do not. There are other issues that affect the soil and the amount of irrigation needed. Cammarata was hired to look at problems in an amphitheater that hosted weekly concerts, some drawing considerable crowds. There might be as many as 5,000 people jumping up and down on the turf. “I had to redesign everything,” he says. That meant not only modifying the landscape, but the soils, irrigation and management practices, as well. The irrigation had to be changed so that the area would not be as wet, so that the soil would not get as compacted, which brings us to water saturation. Cammarata worked to modify the soil structure to promote better drainage. Irrigation systems must be designed to consider soil types, microclimates and plants, all as part of one big picture, not three separate ones. “Everything that I do is meant to keep the proper balances in the soil, understanding plant usage and the water requirements in every landscape,” he says. “This tends to meet or exceed every law or regulation wherever we are hired as consultants. I try to be ahead of the curve.” Done right, irrigation can even help developers get points for LEED certification.

“When properly designed, installed, managed and maintained, horticultural management tools will provide just the right amount of water to our customers’ landscapes only where needed, only in the quantities needed and only at the time needed,” says Cammarata. He believes that most irrigation companies, as well as others in the industry, do not understand soils, plants and microclimates, making it difficult to properly design, manage and maintain landscapes and irrigation systems that are the most effective, even if they have the best equipment. Even if you have a so-called “Smart” controller, if the water delivery system on the landscape is not matching the smart element, then the landscape suffers. Without understanding the area’s plant-soil-water requirement, no product will be the hero that solves everything. Therefore, it is important to create “hydrozones” or valve groups for specific types of plants, based on their water requirements. Appropriate irrigation systems are replenishing the soil profile, not watering plants. In the end, Cammarata is trying to encourage the irrigation industry to take the plant-soil-water triangle seriously.

Doing Business in Challenging Times

Solve Your Labor Issues by Growing Leaders by Meta Levin

The world has changed

When recruiting new people, first give some thought about what is most important to you and your business. Ask yourself, are you hiring for shared values? “Look at your culture,” says Evans. “Are you asking questions around your values?” Evans points to an analogy he heard from Flip Brown, a Vermont based business culture consultant: your business consists of a stool with four legs and a seat: • Values - what you, as an organization believe in, that are shared by the owner and employees • Mission Statement – a clear and concise statement of what differentiates your organization from others • Vision – where you see yourself and your business at a certain point in the future. “The leader needs to set the vision,” says Evans.

since January 2020, when Don Evans presented “Solve Your Labor Issues by Growing Leaders” to an attentive iLandscape audience. But, he says, the basics remain the same. “Let’s focus on the qualitative, on the quality of the people we recruit, hire and develop into leaders on our teams,” says Evans, president of LandOpt, a company that provides hands-on coaching, peer networking and role-specific training for landscape professionals and their teams. Admittedly, iLandscape occurred before the novel coronavirus, COVID19, became a national emergency, when unemployment had hit historical lows and a labor shortage was one of the biggest issues for those in the landscape industry. The recommendation, however, stands.

• Strategy – the decisions and actions that enable you to achieve your vision • Behaviors – this is the seat on which you sit. What behaviors are you forming and re-enforcing among your employees in order to execute the strategy to achieve your vision? The people you recruit are not necessarily those who come from the landscape industry. If they reflect the values important to you and your business, Evans believes that they can be taught the specifics, which means that you should be looking everywhere. The acronym “ABAR” sums it up: always be a recruiter. “Be proactive,” he says. “If you find someone who is a good fit for your team, you will find a way to hire him or her.” (continued on page 54)

Doing Business in Challenging Times (continued from page 52) Evans tells the story about the landscape contractor who was making a purchase at the local hardware store. The clerk was friendly, knowledgeable, energetic and helpful. In other words, he exemplified the values and culture that the landscape contractor wanted in his business. As he completed his purchase, he gave the clerk his business card, telling him that if he wanted a job, to contact him. You can guess the result. The clerk contacted the landscape contractor and now he is a successful account manager in the landscape contracting business. “Hire for attitude,” says Evans. “You can train the rest.”Once you hire someone, training and coaching at all levels of management are important. Continuing it is even more crucial. “It’s all about providing a personal development plan for each member of your team,” says Evans. Eighty percent of job seekers expect and

demand career development. Keep that in mind when you are hiring and managing your employees. This can include many things, but Evans points to the value of peer networking. “Owners can join peer networks; make sure that your managers can, too,” he says. These peer networks have proven to be good training for career development. It’s important to be aware of changing demographics in the workplace, says Evans. This is not your father’s work environment, nor, for that matter, is it yours anymore. Millennials are moving up in the work force and into management. Studies have shown, for instance, in addition to the need for personal development, the Millennial generation (approximately ages 25 to 39) doesn’t like annual reviews. Instead, they prefer ongoing conversations. Evans recommends the “plan and

review” (PAR) process. This institutes regular dialogues about the job and the work the employee is doing. Under this plan, every two weeks the employee completes a form and hands it to his or her boss. A few days later they discuss it. The form includes information, such as the employee’s successes and challenges of the past two weeks, , the priorities he or she is working on, what should be done and on what the employee would like to work. “Eightyfive percent of the talking is done by the subordinate,” says Evans. “Put it on the calendar.” It allows the manager to guide strategy, to get feedback from the employee and gives you a platform and a window into what your employee wants and how he or she is performing. “I’ve been with LandOpt for three years and I’ve never seen a process as on point as this (continued on page 56)

Doing Business in Challenging Times (continued from page 55) one,” says Evans, who has a broad background and grew up on the family farm in Virginia. He spent some time as a corporate lawyer, from which he moved to areas, including sales and marketing, strategic planning as well as general management. “It keeps the lines of communication open.” Evans also stressed the importance of strategy meetings that include the mission statement and company values. “Strategic planning meetings are a group project,” he says. If owners set a clear vision of where they want to take their companies, then the strategic planning meeting is a critical next step in executing that vision. People look to the leader to establish the vision. He had another anecdote to illustrate his point. If the team successfully plans and climbs Mt. Kilimanjaro, it’s great, unless the owner wanted to climb K2.

Make sure your team scales the mountain you want to ascend. Strategic planning needs to be a twoway street, says Evans. He suggests that the general manager be a part of the team, and that, if the company can afford it, bring someone in from the outside to lead the meeting. If the general manager or owner leads the meeting, other team members are likely to defer to him or her, eliminating the ability to have an honest exchange of ideas. If hiring someone to lead the meeting is too expensive, have someone else on the management team lead and let the general manager be a team member. These strategic planning meetings, says Evans, should be a part of the annual cycle. In each successive year, he recommends that the team dig deeper, tweak and refine the plan. Focus on the qualitative, Evans emphasizes. From recruiting to hiring to

executing your strategy, make sure each process is aligned with a focus on quality. If we all do this, our industry will be a welcoming and invigorating career path and our labor issues will be solved.

Diseases & Pests â&#x20AC;&#x201D;

Disease of the Month: Dothistroma Pest of the Month: Eastern Tent Caterpillar

by Heather Prince

Disease of the Month: Eastern Tent Caterpillar

Disease of the Month: Dothistroma

Dothistroma is a common needle blight on Austrian, ponderosa, mugo, red, and scots pines. This fungus causes banding and dieback of affected needles and attacks the older needles. You may see new tips stay green for months, with sections of brown needles behind them. The infection occurs typically from May through October. Small, Common needle blight water-soaked or chlorotic spots develop on older needles, which turn yellow to tan, then brown to reddish brown as time goes on. The spots will often expand into bands and girdle the needle, killing the tip end which turns brown while the base remains green. Eventually the entire needle will die, leaving dead needles attached to the branch for a season or two before dropping. The greatest needle loss is usually seen in spring and summer, and infection usually begins at the base of the tree and moves upwards. Fruiting structures develop on affected needle in spring, and occasionally in autumn. Small, black structures will erupt through the epidermis of the needle and are seen only in affected areas of the needles, not on healthy tissue.

Eastern tent caterpillars (Maclacosoma americanum) are native pests that can quickly defoliate trees. They feed on leaves starting at the margins and moving inward, leaving the midrib behind. These caterpillars overwinter as eggs in dark brown egg masses, with young larvae hatching around bud break. Caterpillars are dark with a yellow-gold stripe down their back and blue spots along their sides. The caterpillars have short velvety hairs with some sparse longer hairs along their bodies and can grow to be two inches long. They create silk tents at the crotches of branches and venture out of the tents to feed on foliage. As the caterpillars grow, tents expand as they provide protection from predators, parasites and pathogens. The tent also has a greenhouse effect, creating a warm, humid environment that is beneficial for larval growth and activity.

Treatment:

Remove tents by winding them around a stick and squashing the caterpillars. By removing tents at night or on cloudy days, more caterpillars will be inside.
