OK, so May has finally arrived, and it looks like maybe Spring has finally sprung. But up until this week, it would have been hard to tell that spring was already here while walking around outside and observing the greenery, or lack of it.
Normally we would be seeing a lot more green this time of year in the way of leaf out on the deciduous trees and shrubs, but those buds are a little more reluctant to open in 2018. In case you were wondering when we can say Spring has actually started, read on…
Depending upon which definition you use, there are actually two different dates that the mark the scientific first day of spring.
1 March 2018 is the first day of the meteorological spring season
20 March 2018 is the first day of the astronomical spring season
Astronomical seasons refer to the position of Earth’s orbit in relation to the sun, taking into account equinoxes and solstices. Meteorological seasons are instead based on the annual temperature cycle and measure the meteorological state as well as coinciding with the calendar to determine a clear transition between the seasons.
Since the astronomical seasons vary in length, the start date of a new season can fall on different days each year. This makes it difficult to compare seasons between different years and resulted in the introduction of the meteorological calendar. This splits the calendar into four seasons of approximately the same length. The astronomical seasons run approximately three weeks later than those of the meteorological calendar.
All this scientific and statistical information aside, for most of us, and particularly those of us in the horticultural industries, the emergence of leaves on deciduous trees and the greening and growing of the grass signals the transition from winter to spring and the onset of the growing season. The flora that we are surrounded by does not know about our Gregorian calendar or the astronomical/meteorological movement of the planets. It is air temperature that is the most important factor in the “leaf out equation” regulating the budburst in woody plants; and the aspects of air temperature that most influence leaf-out timing can be broken down into two components: sufficient chilling in the winter, and warming temperatures in the spring that allow for the subsequent development of buds to the point of bursting. The term ‘chilling requirement’ refers to the exposure of plants to cold temperatures for a prescribed period of time before they will break dormancy. The specific amount of exposure to cold temperatures required to meet this chilling requirement differs among species but prolonged temperatures in the low fifties is the general threshold here in Chicago to initiate dormancy in late fall and to signal the plants to break dormancy in the early spring.
Temperatures here typically average around 51 degrees in the first half of April and 62 degrees for the last two weeks of the month, generally creating enough prolonged warmth to revive dormant plants and initiate the budburst. However, in 2018, we saw one of the coldest Aprils on record for the Chicago area; fourth coldest to be specific, with an average temperature through April 16th of 36.5 degrees; not conducive to helping plants break dormancy.
And for the record, that’s the coldest it’s been in Chicago to begin April since 1926, when the average temperature for April 1-15 was 36.4 degrees. The coldest first half of April on record was in 1881, when the average temperature for the first 15 days of the month was 33 degrees, according to the National Weather Service.
Warm temperatures are only part of the Spring equation that leads to the much-anticipated greening of our landscapes. Photoperiodism, the response of an organism to seasonal changes in day length, also plays a role in regulating the leaf-out of some woody plants. Not all species respond to photoperiod cues, and not all populations of a species have the same requirements. However, photoperiodism is directly associated with the movement of the planets, so it remains pretty consistent year to year in any given geographic region.
Rainfall is the other variable part of the “leaf-out equation”. If April showers are supposed to bring May flowers, we may have to wait a bit for those too. April was not particularly rainy this year. As a matter of fact, we actually had ten times more snow than rain this April; approx. 2″ of snow fell and only .02″ of rain, (compared to an average of approx. 2″ of rainfall).
So now you can put all of these fun cocktail party facts aside and don’t be alarmed if your trees and shrubs are not leafing out yet, or if your hostas, daylilies, and other perennials have not broken ground. The late hard frosts and light snow cover we saw in April may have spoiled the show for some of the very delicate early emerging flowering perennial plants, but for the most part, there will be no lasting damage as a result of the cold weather. Mother Nature has a way of protecting these plants by keeping them in dormancy until temperatures are tolerable for the newly exposed tender growth as buds open up. So be patient, and do not start pulling plants or planning replacements yet. Temperatures appear to have moderated and we are in store for a lot of sunshine in the short-term forecast so what you may have already written off as winter kill may surprise you and break bud in the next couple of weeks.

I think when I started working for my dad 24 years ago, he thought, “she’ll get bored, find something she loves and move on.” What I think both of us didn’t expect is that I did, find something I loved.
There is so much that I love about our company. I was first struck by how hard our men work, and what they can accomplish! I love when our customers tell us how much they appreciate how kind our people are. I love the smell when you walk into a green house. I love the moment when the sun is rising and the trucks are rolling out. But I think what I love the most is that I get to spend time with my dad, because when I was growing up, he was spending time growing the business.
My dad has a tremendous work ethic. He gets it from his Italian immigrant parents, Mary and Corrado Vignocchi. Their home was a modest farming town in Northern Italy. They fled Italy before the war, both to escape the terror and find much needed work. What they found here was hope, but it wasn’t easy.
I remember those afternoons with my grandparents, when it was just the three of us, I would say, “tell me.” “Oh silly girl. Tell you what?” “Tell me what it was really like.”
They would tell me stories about a time before they could communicate in English, how people would treat them, with harshness and disrespect. It still makes me heavy of heart when I think of it, and I think of it often, to remind myself.
They would tell me although it was hurtful they didn’t care. They were here and wanted to provide a better life for their children. A life of possibility, which proudly, they did…look at my dad.
This brings me to the ultimate reason I stay, through a recession, through climate change and even through our current labor shortage.
You see, dad and I, like many in our industry, are a product of immigrants. My dad has always been conscientious of that. In our 49 years in business my father has made helping the people that work for us as important as helping our customers.
That’s something I want to carry forward, a higher purpose for working as hard as you can for something bigger than yourself. Hopefully in honoring my heritage I will hear of yet another college graduation that fills yet another family with pride.

I recently came across an article in The New Yorker titled “Home Invaders” about the history and increase of stinkbugs in homes. You know, those lazy, ugly bugs that look like little brownish gray shields. Since I am in the landscape industry I have a pretty good working knowledge of insects, skeptical this would enlighten me even more, I delved in.
Boy was I wrong, it was fascinating! If you are like me anyway and think bugs are fascinating…
The brown marmorated stinkbug (halyomorpha halys) was brought over from, most likely, East Asia, China, Taiwan, Japan or South Korea. The first sighting of the insect in the United States was on September 21, 1998 in Allentown, Pennsylvania. From that first discovery the insect population has grown in insurmountable numbers. This is not a good situation because the stinkbug does not have one food source it damages, like the emerald ash borer, but many. Sweet corn, soybeans, tomatoes, bell peppers, green beans, peaches, to name just a few. The article states “In orchards, they were crawling by the hundreds on every tree; so many had invaded corn and soybean fields that farmers had to turn on the windshield wipers in their combines while harvesting. Afterward, it wasn’t uncommon to find stinkbug damage on every single ear of corn.”
Insecticides do very little to rid these bugs due to their shape, the way they feed and the way their legs hold them above the top of a leaf (which prevents contact with the insecticide). Those characteristics that make insecticides non-effective in farm fields are what make spraying them in your home ineffective as well.
So, calling “The Orkin man” might prove costly and do nothing to rid your home of these pests. And a quick note, don’t squish or squash these guys as means of elimination, they got that name for a reason.
My question? “So why do so many show up in my house?” Well, that is the same reason there are thousands of them in farm fields. When the stinkbugs find food, or a place to overwinter in your attic, they release a pheromone that summons their friends. That pheromone can last for a year which can attract further generations into your home.
Is there good news? Yes, in summer the insects leave your home to reproduce and eat and in winter they enter, unfortunately in your home, a state called “diapause-a kind of insect hibernation.” This makes them extremely easy to catch in a cup and release back outside when they are hanging off your drapes or your walls.
The article is completely worth the read, if you have time on a Saturday morning while enjoying a cup of coffee. At least that is what I did.

TO SHEAR OR NOT TO SHEAR…
With spring right around the corner, those of us in the environmental services industry are happily ready to leave winter in the rear-view mirror and prepare for the new growing season. Over the next couple of months, here in the Midwest, deciduous trees and shrubs will come back to life and flush out their first new growth of the season. Typically, that is when most property managers and building owners expect to see their contractors break out the power shears and go to work shearing and shaving the plant material around their communities and office parks. We at ILT would like to ask you to consider supporting the movement to reverse that trend. In case you were wondering what that movement is all about, read on…
For many years now, we have been advocates of the anti-shearing movement, recommending to our customers that it is in their best interest, and ultimately in the best interest of their plant material, for our crews to leave the power shears in the truck and opt for the use of the hand pruners. Tree topping and unsustainable shrub shearing is, for the most part, ruining commercial landscapes and this practice needs to be replaced predominantly by natural selective pruning programs.
Shearingis the all too common landscape maintenance practiceof non-selectivepruning that forms plants into shapes that differ from theirnatural growth habit. Unsustainable shearing, i.e. the shaping of trees and shrubs into the endless balls and boxes that are seen on most commercial and many private landscapes, is resulting in less attractive landscapes, unhealthy growing environments, and expensive replacement costs for plants that cannot live out their normal life span.
Shearing creates a twiggy outer shell that gets ever denser and collects more deadwood and dead leaves every year, causing the condition commonly referred to as witches’ broom. These clusters of witches’ brooms create the perfect protected place for pests and diseases to flourish and they detract from the health and longevity of the plant. The weakened plants now require more water, nutrients, and pesticides just to survive, driving up irrigation and material costs. Eventually, as the plants succumb to this unsustainable shearing, more and more dead wood becomes exposed, detracting from their natural beauty. Ultimately, the plants either die prematurely, or get so bad that they cannot be saved and need to be replaced well before their normal life span.
Shearing also encourages water sprout regrowth; those straight-up, skinny, rapidly growing shoots that are a nuisance, breaking the natural architecture of the plant with weak unproductive growth. Water sprouts need to be cut off or re-sheared frequently to keep the plant looking neat. But shearing those off just creates more sprouts, locking the plant into a high maintenance routine. While many people like the look of a tightly sheared plant, the reality is that the sheared plants only look good for a short while before they need to be sheared again; promoting this unsustainable cycle.
Selective pruning, on theotherhand, promotes the health and natural shapeof a plant, saves money byreducing overall maintenance, and extends the life span of the landscape. Selective pruning techniques open up the center of the plant, with precise targeted cuts, allowing air and light penetration to create a stronger, healthier growing environment. In addition to being bad for the plants, shearing of non-hedgeplants is counter-productive,resulting in higherlaborcosts since shearingrequires multipleoccurrences every season. Although selective pruning is much more labor intensive, selectively pruned plants need to be pruned only once every one to five years; so, in the long run, selective pruning practices will save on labor.
For the selective pruning movement to catch on, we need to address this common misconception that many people have that a plant needs to be sheared tightly to make it look like it is being well maintained. Under most circumstances, shearing actually subverts a tree or a shrub’s natural beauty.Every plant in a professionally designed landscape has been chosen because it adds something special to the overall design. It may have nice flowers, interesting texture, or artistic branch structure. Whatever the feature may be, it should be accentuated with pruning, not destroyed by shearing. A landscape designer’s skill is in creating a natural but interesting, seasonally changing, and aesthetically pleasing picture. Untimely shearing done by untrained contractors destroys that picture, making everything look the same-smooth and round, square and boxy, etc. Shearing continually chops away the new, fresh growth leaving old decaying or dead wood in its place. Additionally, this frequent, undisciplined shearing will often remove flowerbuds that are ready to bloom or those hardening off to provide next season’s color display.
Admittedly, some designers do get carried away with their own desire to be unique or unduly creative, calling for incompatible plant varieties to be placed in areas where they are doomed to be sheared back constantly (under windows, along sidewalks, against foundations, etc.). Then after the designer is long gone, the landscape crews are held responsible for maintaining the un-maintainable. In places where plants have been placed in unsustainable spots in the landscape, they should be systematically removed and replaced with more suitable varieties whose natural growth patterns are better suited to the space. Formal shearing should be reserved for “pruning art” like topiary or formal hedges, and only with plant varieties that are selected because of their ability to withstand frequent shearing.
As a customer, you must understand that most contractors are happy to accommodate your request to tightly shear everything on the property. Maintenance is a business, and most lower priced contractors will be happy to grab the shears and power through all of the pruning needs to be able to move rapidly on to the next task or their next property. Quick shearing fits nicely into a profitable regimen and helps them keep their prices low. However, what they don’t tell you, because they probably don’t know, is that selective and rejuvenative pruning, done properly either in-season or over the winter months, can all but eliminate any need for frequent shearing. That reduction of labor can often lead to saving you money or allowing for even more time on your property for other maintenance operations.
Almost anybody can shear plants without training, but selective pruning is more complex. Crews require training to understand how this kind of pruning is done. Trained and experienced crews know what to do with each variety of plant in terms of the timing and execution of pruning operations. That type of knowledge is what separates the professional landscaper from the landscape laborer. A laborer simply does what he/she is told; a professional knows what to do. Those professionals get paid better wages so consequently the companies that employ those professionals need to charge a little more. As the saying goes, “you get what you pay for”.
If your doctor were to tell you to stop eating spicy foods to help ease the stomach pain that brought you to his office, would you tell the doctor to go ahead and remove your gall bladder anyway because that is what you think should be done. Probably not. You take the doctors professional advice because that is what you are paying for; and so it is with the professional contractor you hire to manage your landscape. If your preconceived expectations do not align with the sound horticulture practices your contractor is recommending, take a moment to reconsider and allow the professionals to provide the service for which you are paying. As a property manager or building owner, paying a little more for professional service will result in long term cost savings on premature replacements and unnecessary maintenance, and provide you with a more appealing marketable property.
In order for the anti-shearing movement in the landscape maintenance industry to get the necessary traction to affect real change, customers and contractors alike must adopt selective pruning as the new normal. Landscape business owners must buy into the need to train crews in selective pruning techniques and wean them off the shearing default. Property managers and building owners must adjust their expectations, embrace the natural growth habits of the plants in their landscapes, and take the final step to demand selective pruning be done on your properties.
The purpose of this piece is to promote the demand for better pruning by getting the information out to you, the professional property manager or building owner. Reconsider your expectations. Tour your properties. Examine your landscaping. Talk to your contractors. Specify selective pruning to be done on all of your new plantings; urge your contractors to rehabilitate the previously over sheared plants where possible or replace them where necessary. If you demand that your contractors leave the power shears in the truck, over time, your landscapes will be transformed into the lush, healthy, low-maintenance, natural looking gardens that nature intended.

This morning one of my two favorite moments happened simultaneously…laying in bed while it is still dark out listening to the rain and hearing the distant sound of a train’s horn. It might seem like a simple thing, but simple things can transport us back to simpler times.
The sound of a train blowing it’s horn in the early moments before daybreak bring me back to time spent at my mother’s family farm in Indiana. It conjures a picture in my mind of crisp red and white, an apple orchard, and my grandfather sitting alone in the kitchen before dawn with a cup of coffee, his profile illuminated by the small light on the kitchenstove.
My family is very proud of our small farm and their father, mother, brothers and sisters, who worked so hard to provide the necessities. You see, they were tied to the land. Growing to feed their families. They were prey to the same things we are prey to in our business…the weather, pests, disease, and ah yes…little critters.
I remember my grandfather had a book that outlined how and what he would plant each year, and how he intended to rotate those crops annually to get a better yield. Thinking back I wished I had had more interest, asked more questions. Maybe he had some secrets I could have used, not scientific research like we have abound today, but something he knew in his gut.
I was fortunate to have both sets of grandparents come from a place and time that held enormous respect for the land’s ability to provide beauty and sustenance. They only bought what they could not grow and they worked painstakingly hard for what they had to buy.
When my husband and I started a family, one of the first things we did was create a vegetable garden. I would constantly seek my mother and my grandmother’s advice. I would create a book, like my grandfather and make certain to rotate my crops. I made certain it was pretty as well. We also battled bunnies, pests, weather and disease. Although that garden fills me with immense satisfaction, joy and pride, it pales in comparison to the gardens of both of my grandparents and my mother’s.
But I do it, not just because it makes me think of my family, but because it reminds me and teaches my daughter…or as my mother says, “the land will always provide.”

One of our invaluable assets is our sister company, Montale Gardens. Located in Wauconda, Illinois, Montale is a wholesale nursery celebrating its 23rd birthday this year. With each year we increase our diversity of products. One of our most successful lines are our container shrubs. The quality cannot be rivaled, in our humble opinion…here are some highlights of what make them and our other products so special.
Montale is a container nursery. What does ‘container nursery’ mean, exactly?
It means that we grow our plants in POTS.
Our shrubs and ornamental trees are not field grown – meaning dug out of the field, then balled and burlapped (B & B). Our plants’ lives are started and nurtured in their containers, and that is the way you purchase them.

It has been years since we have to wait until the middle of January in Chicagofor the first significant accumulating snow of the year (+2″), but here we are. It is often right after the first significant snowfall of the season that we hear from many concerned customers about the potential damage that snow may do to their trees and shrubs. While snow is vital to the winter survival of plants and trees it can create some problems for your plants under extreme conditions. In case you were wondering how to avoid damaging your plants this winter, read on…
Of course, the best solution is not to cover plants with excessive snow at all. Avoid plowing, blowing, or shoveling over the top of your plants. Mark your beds in Fall with posts or reflectors if necessary to make them more visible under extreme snow conditions.
Avoid piling “salty” snow near plants or on lawns. If you choose to use ice melt products such as rock salt on your walks and drives, keep in mind that this, mixed with the snow and slush that is piled around plants, can leach into the soil and harm roots. Plants will absorb these contaminants in the Spring which may cause die back and even death. If you must “salt”, use one of the more environmentally safe products such as calcium or magnesium chloride or an ordinary, inexpensive garden fertilizer, sand, or kitty litter mixed with equal parts of “safe” salt.
Consider these plant care tips now before the snow really starts to fly as it is easy to forget them in the throes of one of Chicago’s blizzards or ice storms. By taking extra care now when removing snow or melting ice you can keep your trees and shrubs safe from snow injury and you will find them to be more hearty and healthy come Spring.
