Turf Management: Adjusting to Drought

If your property does not have an automated irrigation system and you have not watered your turf regularly this summer, you may have noticed it is turning brown, indicating it is reacting to the impact of the summer drought we are in the midst of here in the northern Chicagoland area.  Your grass has a natural drought defense system which shuts down the expendable parts of the plant in an effort to keep its roots alive, hence the brown coloration at the surface. The good news is, turf grasses are resilient plants and can survive a long time without water. The bad news is, not only does the brown grass not look good, the dormant grass will become more susceptible to invasive weeds and crabgrass which tend to find room to root and grow in the stressed turf.  Generally, though, once moisture returns, most grasses will recover without leaving permanent damage.  The weeds and crabgrass can be treated, and your once beautiful lawn should be restored.

The simplest and best practice that we have found for helping the turf survive and recover from the effects of a drought, if regular watering is not an option, is to make some simple adjustments to our mowing operations.  We raise our mower blades slightly, to 3″ – 3.5″, to minimize the heat/sun exposure of the root systems of the turf that results from mowing too low in these hot, dry conditions.  Additionally, you will find that we will forgo mowing whenever warranted, on a given visit, if the grass has gone dormant and has not grown sufficiently to necessitate a mowing.  This will prevent the potential damage that could be done to the dry, brittle grass blades as the heavy mower wheels roll over them.  The added benefit of not mowing is the extra time we can spend on your property detailing and performing more labor-intensive gardening operations.

Furthermore, the longer grass blades will shade the ground underneath, keeping it cooler and inhibiting water evaporation. The granular fertilizer we apply during your lawn care visits will stimulate new growth once rain returns or the lawn is watered. If you are going to water your lawn, you must be consistent. If you cannot deeply water your lawn one inch or more per week, it is better to let your lawn go into a state of dormancy.  Light, infrequent watering can do more harm than good as it encourages shallow root growth which then makes the turf even more susceptible to disease and insect infestations during periods of stress.  So, it is best to commit to keep up with the watering or let it go and wait out the drought.

When temperatures start to cool down and rainfall increases, your lawn should come out of dormancy and begin to recover. The turf plants will start growing new roots and new plants will germinate to replace those that were damaged or even killed during the summer. Core aeration and over seeding in the fall are two great ways to help your lawn recover from a tough drought season, like the one we are currently experiencing. Strengthening the roots is critical to maintaining healthy turf, and the core aeration process will open the lawn to provide more air, water and nutrients into the turf root zone.  Following up the coring operation immediately with over seeding will help to generate new seedlings to fill in sparse areas. Grass seed needs to come in contact with soil and receive adequate moisture to remain viable once the germination process begins. A good portion of the seed will end up in the core holes, which ends up being a great place for the seed to germinate. The soil in the core holes will remain moist and cool, and the seed will have a much better chance of germinating.

Morton Arboretum Troll Hunt

This past weekend, on a particular hot sunny Chicago day, our family thought it would be an adventure to visit Chicago’s Morton Arboretum to see the Troll Hunt Exhibit…with our 9 year old daughter.  Did I mention it was very hot, very sunny, AND that the trolls in some places are 3/4 of a mile from parking areas?  It was really fun for the first half hour, let me tell you.

But although nature became a bit of a bore to our darling daughter, the Arboretum is a marvel to me.  It is nothing like a Botanic Garden, it is more like an organized forest for one.  Another shocking revaluation?   There are weeds, lots of them, which I found mind blowing but very refreshing.

The Arboretum was founded in 1922 buy the son of the man who founded Arbor Day.  It spans a tremendous 1,700 acres holding more than 222,000 live plants representing nearly 4,300 taxa from around the world.  What is so wonderful is that it made me feel so small, so unimportant, yet so at peace.

The Trolls, although fantastic, were such a secondary draw to all of the different species, elegant groves, and meandering walkways.  One thing I did appreciate about the Trolls is they were fashioned to completely meld into nature…as if they lived there in harmony in what felt like the most peaceful place on Earth.

During these times when tensions always seem to run high and meaningful personal interaction is on the decline, I encourage you.  Take your family, take a friend, go with a neighbor.  Walk around and take in the splendor.  Talk to one another.  It’s good for your soul.

In case you were wondering: Has spring sprung?

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.

Why I do it might be simpler than you think

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.

Owner ILT Vignocchi

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.

ILT Insider: Stink Bugs

Our Core Values:  Quality  Honesty  Pride  Teamwork  Cleanliness  Safety  
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.
