My guess is that many people don’t find dirt very interesting. But the truth is that people study it intensely. We actually employ someone who is a soils expert, Mike Curry!
So what exactly Is pulverized topsoil? Topsoil is the upper layer of the Earth’s crust, usually the top 2 to 8 inches. It has the highest concentration of microrganisms and organic matter and is where most of the soil’s biological activity occurs. Plants generally sink their roots into and obtain most of their nutrients from this rich layer.
This high concentration of organic matter is actually what turns soil black. So the darker it is, the more nutrients in the soil, the better your plants and turf will do. Ever notice “grey” colored dirt. It often occurs in areas where a lot of salt is applied during snow removal services. That’s because those microorganisms have been killed and the organic matter is leached out.
This is why it is so important to install mulch and compost in planting beds. It helps provide a protective layer and breaks down over time, reintroducing those beneficial nutrients back into that top layer of soil.
It’s also equally as important that you topdress your lawn with some kind of compost when core aerating and overseeding for the same reason.
Most people probably don’t know how topsoil is created. It’s a fairly simple process. Most often topsoil is taken from construction sites where there are large open spaces that need to be excavated anyway. That soil is then “pulverized” through a machine to remove any debris as well as giving it a more consistent texture that makes it easier to spread and fine grade.
Turning 50 is such a milestone for any business. Dips in the economy, increasing regulations, labor issues and shortages. There are so many ways a company can get off track. As I contemplate where we have been, of course I think of our unwavering reputation for integrity, artistry and quality. You consider the massive golf courses, Chicago Botanic Garden installations, as well as corporate and municipal work. I regard those residential projects that not only won awards but gave our employees such satisfaction and our customers heartfelt joy.
But to me it is more than that.
I don’t know if I have a memory when ILT didn’t exist. You see, as ILT turns 50, I will be turning 47. The memories of our company are like fabric woven into my life.
When I watch the countless trucks and trailers roll out of the yard at sunrise each and every morning I indulge the nostalgia of our company’s youth.
I remember Sorney Leahy who let me sit inside his desk drawer when I was very small and let me play with his phone. Or going to a job site with my dad on a Saturday. He’d hoist me up on his shoulders and then put me down so I could hug my Nono who was working with our men. A favorite is my mother who would spend hours picking up sticks before the maintenance crew came to our house so they would not have to bother.
50 years ago there were no computers. Dad used to spend countless nights drawing plans, scrunching up vellum with discarded ideas and yes, taking calls from his customers on his home phone.
I think life is different when you are in a family business. Of course it is hard and there are arguments, lots. But there is a short cut with family that makes it easier, because you know in the end, you will always love one another.

No one is really enjoying this latest prolonged blast of cold weather. We are all stuck inside doing our best to keep ourselves (and our kids) entertained and warm. We must have been due for this as we have been spoiled with mild winters the last few years. So, those mild winters, along with other things, have encouraged an increase in insect populations we have seen in our trees, shrubs, perennials and lawns, right? This arctic blast will surely help reset those bloated insect populations, correct?
The answer to those questions is complicated. This is because many insects have adapted ways of making it through a cold, harsh winter. Migration, hibernation, freeze tolerance (insects can produce an anti-freeze to keep them safe) and freeze avoidance are just some of the ways insects make it through.
In many cases it is the spring weather and not the winter weather that can determine the fate of insect populations.
For example, warm early springs can encourage insects to leave their winter hiding spots to search for food. If this is done too early there is not enough new plant growth for insects to feed on. This can lead to insect starvation. On the other hand, a cold spring will keep the insects in hiding longer which means they could miss one or two reproduction cycles. This leads to lower populations until summer. Just like baby bear’s porridge and rocking chair the conditions have been “just right” the last few springs for insect population growth and has not been greatly affected, one way or another, by our mild winters.
Heavy spring rains can also impact insect populations. Spring rains will increase mosquito and aphid populations that need the water to reproduce. However, heavy rains will decrease grasshopper (because their dormant eggs laid in the ground get saturated with water and rot before they hatch) and spider mites populations.
The, sort of, good news is this prolonged artic cold should cause some insect die back. The issue is, when talking about dieback, is this dieback not only effects “bad” insects, but the “good” ones as well. To make it through the winter bees flutter their wings, shiver and are in constant motion in the hive to produce heat for the hive and most importantly, the queen. Due to this constant motion bees need to eat a lot. A bee hive can go through thirty pounds of honey in a winter. If they run out of honey or it gets too cold the hive could lose their queen which effectively kills off the hive. So, where the mosquitos and aphids might experience some dieback so might the bees. Nature is a balance and we must be careful what we ask for.
Every year brings something different and it is our job here at ILT Vignocchi to study those treads so we know what to look for from year to year. We will know more when spring arrives what these temperatures did to the overall insect populations.
In case you were wondering…
Every autumn in Illinois brings with it a breathtaking change of color in the leaves of our trees, but although it’s late September, temperatures have been steadily topping out in the nineties every day. Not a traditional sign of Fall, yet the trees are changing color and dropping leaves as if they were not aware of the hot and humid weather.
Aren’t the leaves supposed to change when it gets cooler and we see some frosts overnight?
Do the trees know what time of year it is despite the unusually warm temperatures?
One explanation, according to Native American myth, is that the hunters in the Heavens killed the Great Bear in autumn and its blood dripped over Earth’s forests coloring some of the leaves red. As the hunters cooked the meat, fat dripped from the Heavens and colored some of the leaves yellow.
Not scientific enough for you? Need a more botanical answer?
In case you were wondering what actually initiates the changing color of the leaves and their eventual fall to the ground, read on…
Most people think that cool weather or frost causes the leaves to change color. It is true that there is usually a correlation between the cooler air and the onset of the autumn show. However, while temperature may impact the color intensity, it has less impact on the timing of the color transitions we see in the Fall than do other factors.
A quick trip back to high school Botany 101. During the spring and summer most of the foods necessary for the tree’s growth are manufactured in the leaves. This food-making process takes place in the numerous cells containing chlorophyll, which gives the leaf its green color. This extraordinary chemical absorbs the energy from sunlight that is used in photosynthesis, the transformation of carbon dioxide and water to carbohydrates, such as sugars and starch.
In late summer or early autumn, the days begin to get shorter, and consequently, the nights are longer. Like most plants, deciduous trees and shrubs are rather sensitive to the length of the dark period each 24-hour cycle. When nights get long enough, the cells of the leaves begin to block transport of materials such as carbohydrates from the leaf to the branch. They also block the flow of minerals from the roots into the leaves. Because the starting time of the whole process is dependent on night length, fall colors appear at about the same time each year in a given location, whether temperatures are cooler or warmer than normal.
The fact is, the vivid yellow and orange colors have actually been there throughout the spring and summer, but we haven’t been able to see them. The deep green color of the chlorophyll, which helps plants absorb life-giving sunlight, hides the other colors. In the fall, fewer hours and less intense daylight prompt the leaves to stop the food-making process. The chlorophyll breaks down, the green color disappears, and the yellow and orange colors already in the leaf become visible again to the human eye. As the trees break down the green pigments and nutrients stored in the leaves they are shuttled into the roots for reuse in the spring.
Along with the green pigment of chlorophyll are carotenoids, yellow to orange pigments, which, for example, give the orange color to a carrot. At the same time other chemical changes may occur which produce red anthocyanin pigments resulting in even more variation in the Fall color scheme. Some mixtures give rise to the reddish and purplish fall colors of trees such as dogwoods and sumacs, while others give the sugar maple its brilliant orange. For most of the growing season these colors are masked by the great amounts of green coloring.
The variations in Fall color are due to the mixing of varying amounts of chlorophyll residue and the other pigments in the leaf combined with a varied response to weather conditions. For instance, as the nights become cooler, the sugars trapped in the leaves of some oaks and maples will often form a red pigment. The degree of color will also vary from tree to tree. Leaves directly exposed to the sun may turn red, while those on the shady side of the same tree or other trees may be yellow.
As the fall colors appear, other changes are taking place. At the point where the stem of the leaf is attached to the tree, a special layer of cells develops and gradually severs the tissues that support the leaf. At the same time, the tree seals the cut, so that when the leaf is finally blown off by the wind or falls from its own weight, it leaves behind a leaf scar. Most of the broad-leaved trees in Illinois shed their leaves in the fall. However, the dead brown leaves of the oaks and a few other species may stay on the tree until growth starts again in the spring.
In general, autumn weather conditions favoring the most brilliant colors are warm sunny days and cool, but not freezing, nights. When there is mainly warm, cloudy and rainy weather in the fall, the leaves may have less red coloration. A few hard frosts can cause the leaves to wither more quickly and drop to the ground.
So, in case you were wondering, with all due respect to the Native American myths, it is a combination of temperature, light, and water supply that have an influence on the onset, the degree, and the duration of fall color.
Enjoy it while you can, because it doesn’t last long!
They all look the same from a distance but show subtle differences when examined closely.
The same might be said of snow removal contractors. We may all look the same at first glance, (trucks, tractors, plows, etc.), until you take the time to find out a little more about what we do and how we do what we do;
and you should take that time.
The subtle (or sometimes extensive) differences in capabilities, commitment, and conscientiousness will have a significant impact on the performance on your property; and that performance can make you, the property/facility manager, look like a hero to your residents, tenants, and employees…or not.
Here are five important lines of questioning to help you ensure that you are hiring the contractor best suited to make you look like a hero.
Contract terms have many variations (per plow, per inch, lump sum, time & material, etc.). You need to have clear terms that suit your specific needs, with reliable pricing, and no surprises. While cost is always a factor when making contractor choices, the less obvious consequences of using a lower priced but ultimately incapable snow removal contractor can cost you much more than money if that contractor fails to perform during one of Chicago’s challenging winters. Additionally, if those less expensive contracts are peppered with “extra” charges, you can find yourself paying much more than you would have had you chosen a more comprehensive service provider.
Do you handle the snow removal work in-house with your own employees or do you need to rely on the help of outside subcontractors who may not offer the same level of commitment to the work?
Who are some of the customers you work with now that I can talk to about their experience with you?
How are your crews dispatched and monitored throughout an event?
Do you rely on media broadcasts, airport reports, your own production yard, or will you send a representative out to my property to assess conditions on the site prior to mobilization?
What is your reporting process to ensure that I will be kept informed of progress and problems throughout a weather event?
Who will be available to me for communication regarding issues and special needs?
What is your policy for repairing or resolving damage that occurs as a result of the snow removal efforts?
Taking the time now to find out a little more about the differences between contractors by asking these important questions will help to ensure that you are using the company best suited to satisfy your needs.
At ILT Vignocchi, we welcome your scrutiny; and if you become a customer, we will make you look like a hero.
Call or email us today and find out more about the ILT difference.
Most people think of fall as the end of the growing season and the beginning glimpse of another Chicago winter. Well try to look at it as an ideal time to plant!
Fall is a perfect time for planting shrubs, trees, grass seed, and even perennials if they have a developed root system. Fall planting gives plants time to develop roots before winter’s blustery conditions. The conditions are also less stressful and there may be more reliable precipitation.
What happens during fall conditions is a plant’s leaf and flower production is usually slowing down and approaching dormancy. Therefore, a plant can focus on root production. Roots continue to grow when other parts of the plant are not. Generally speaking, root systems will keep growing as long as the soil temperature is at least 50 degrees.
Although we generally get more rain in fall, the good news is that plants use less water then. Because days are increasingly shorter and cooler in the fall, plants are going to be photosynthesizing less and using less water.
Fall is also when depleted nurseries can begin to dig plants again, so varieties that were either unavailable or just downright unsightly in July and August, may become available.
Finally, don’t forget about BULBS! Its often surprising why more people don’t take advantage of this relatively inexpensive way to welcome in Spring. To achieve a gorgeous Spring show bulbs are planted in late fall.
If you’d like to start planning a fall project, it is right around the corner, so call us now and we will be happy to assist you!
After an uncharacteristically hot and dry June, Mother Nature just sent us a harsh reminder of her ability to restore rainfall statistics rapidly.
Unfortunately for many homeowners and businesses, this reminder came in the form of a seven-inch downpour over a 24-hour period that is still causing overflow and flooding around local rivers, lakes, and retention ponds.
While it is difficult to predict and prevent the kind of flooding issues that are created by such catastrophic weather events, these events serve as a reminder to property owners, both commercial and residential, to be more aware of the impact that water flow has around your property. Having a well-conceived and expertly executed drainage system around your buildings and grounds can mean the difference between staying high and dry through any weather event, or dealing with flooded yards, basements, parking lots, and roadways.
Generally, rainfall is the catalyst for creating drainage issues but ground water, specifically the location of the water table, can also play a role in the ability of water to move by design. Where land is flat, soils are dense (clay), or the water table is high, a well-designed drainage system is a priority. Consideration of grading, water flow, and proper drainage is essential to prevent minor issues during normal weather and to minimize major damage during catastrophic events like the one we experienced here in northern Illinois last week. Without proper drainage systems in place, water can enter and undermine structures, damage drives and roadways, cause erosion issues, and drown expensive plant material.
It is not always enough to rely on the original drainage plans that were created for your property when it was first developed and constructed. Typically, the more recent the development took place, the better the chances are that the drainage systems were designed and constructed to effectively move water around the property. Older properties may have experienced settling, ground shifts, changes in water tables, neighboring development, or many other factors that can influence the effectiveness of these systems. New or old, it is a good idea to observe and review the water flow issues on your property before a major problem occurs.
SURFACE WATER is one of the more common problems associated with improper or inadequate drainage systems. Sites with clay soils will likely have issues with lingering surface water. By design, developed land should be graded to drain so that water flows through swales or sheet drains across turf or pavement to the curb or storm drain. The reality is that builders don’t always get their grades right and water becomes trapped, causing puddles on pavement, backflow against foundations, soggy zones in lawns, and muddy planting beds.
Downspout/sump pump discharge is a huge contributor to surface water issues. Enormous amounts of water can come off a building’s roof or be channeled into a sump pit during a typical rainfall. This water is often just re-directed back along the foundation of a building where it can go right back into the sump pit or collect on the surface of the ground around the structure.
SUB-SURFACE WATER collects underground, and becomes trapped when there’s poor drainage due to the existing soil structure or high water tables. When it freezes and expands, the potential for damage increases. The frozen water pushes against your foundation and paved surfaces, causing heaving, cracking, and structural damage.
Solutions to improper site drainage can range from the very simple to much more complex depending on the nature of the issue and its underlying cause. Conceptually, solutions fall into two basic categories.
- Capture the runoff and store it for reuse or allow it to percolate back into the soil. Rain barrels and cisterns are used for storage of runoff water for use later as manual watering sources. Dry wells, French drains, rain gardens, and specific soil amendments can be used to collect and redistribute water back into the surrounding soil.These solutions have many environmental benefits such as reducing runoff from your property, filtering runoff, watering your yard, and recharging groundwater.
- Intercepting and redirecting runoff provides an opportunity to safely discharge high volumes of water to a place away from the problem area(s). This can be done using swales, French drains, catch basins, underground pipe assemblies, or downspout/sump pump extensions with splash blocks. These methods of rerouting water can also be combined with other capture and storage elements to provide even more benefit.
Please make note that whenever you are redirecting runoff, you must send it to a suitable outlet. Discharging runoff to an unsuitable area will just move the problems downhill. Be aware that redirecting runoff without collecting it or allowing it to percolate into the soil can negatively impact neighboring properties.
The first step in solving drainage issues on any property is discovering that they exist. Problems like foundation seepage and erosion might not be obvious until a major issue develops at which point resolution can be expensive and complicated. To become aware of potential trouble spots, walk your grounds after a rainfall event and look for places where water has collected.
Does it take more than an hour or two to dissipate after a heavy downpour?
Are there signs of erosion around the downspouts or sump pump discharge points?
Are you finding soft, wet spots in the common turf areas that do not dry out readily?
Are you seeing a decline in the health and appearance of plant material located in the collection areas?
These are just a few of the signs that water is not percolating or moving appropriately around the grounds of your development or commercial property. Time to consider having an expert come out and assess the problems. ILT can do simple visual inspections or accurately read existing grades by laser transit to establish the exact topography no matter how flat the site may seem.and determine precisely where and why water is moving the way it is on your property. From that information, we can evaluate and present potential solutions for your consideration.
While last week’s flooding can serve as a reminder of the devastating impact heavy rainfall can have, it does not take a seven-inch downpour of water to cause damage around your property. Finding and resolving water flow issues before they become expensive problems is always a better solution.
Call ILT Vignocchi today and we can start a conversation about resolving water flow issues at your HOA or commercial building.
