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.

ILT Insider: Overwintering of Insects

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.

Nothing like a walk in the park

For all intents and purposes, the winter that came in like a lion is going out like a lamb.  It is time to start thinking about using the landscaping around you again.  Yes, I said “using” the landscaping.

In case you were wondering how you can personally benefit from using the landscape around you today, read on…

Stress and stress-related illnesses, as reflected in medical records, have increased dramatically among adults and children in Western societies. We have probably all heard of one study or another linking exposure to nature to reduced stress, lower anxiety levels, and help with symptoms of depression.  The studies all underscore what we already intuitively know.  We can relax in quiet, natural settings much more than we ever could in our offices or typical urban settings. Consequently, in addition to being a huge contributor to the overall value of your commercial property and providing significant marketing appeal, well designed and accessible landscaping can provide a valuable oasis for your employees and residents.

The simple fact is that our fast paced, plugged in, always “on” lifestyles give us brain fatigue.  It makes our brains tired of constantly being alert and aware (how many times did you check your smart phone since you began reading this piece?).  A “walk in the park” can go a long way to clear up the resulting brain clouds. 

While natural settings do still engage our brain, the engagement is effortless.  You don’t even necessarily have to enjoy nature or walking to get the benefit.  Exposing oneself to nature, even during the winter, or even looking at images of nature engages our so-called involuntary attention, which comes into play when our minds are inadvertently drawn to something interesting that doesn’t require intense focus, like a pleasing picture or a pleasant landscape feature. We can still talk and think while our brains are noticing and appreciating the element, but it holds our attention while it induces reflection.

AS THE SAYING GOES – YOU DESERVE A BREAK TODAY!

The science behind this theory is real, and probably nothing new to you so allow this to serve as a reminder.   Go for a walk in a green space around your building or in your community, or find a window where you can just sit and gaze out at some greenery.  This is not unproductive lollygagging.  On the contrary, it is likely to have a restorative effect on your brain, recharge your mental batteries, calm your nerves, and make you more productive.  If nothing else, a walk in the park will give you the ability to stop “doing” all the time and start “being” some of the time.

“Take a walk outside, it will serve you far more than pacing around in your mind.”

Inspiration from Net Zero Water

Our industry is one that produces a lot of waste and from our equipment, a good bit of pollution.  I’ve always found it ironic that we as individuals are driven by an overwhelming love of the beauty of nature and all it provides, but as one large machine, we seldom exercise a desire to protect that which we love on a larger scale.

To a certain extent we are limited pursuing greener methods on all sorts of fronts, state and local ordinances, competition, even our customers.

However, I recently heard about a project in Oregon that inspired me to push back on those restrictions to better do our part in saving our planet.

There is a new proposed development in Oregon that will have no carbon footprint.  Seriously. Think about that.  100 percent of the developments water will come from captured precipitation or reused water that is appropriately purified without the use of chemicals.  In addition, 100 percent of all stormwater and building water discharge will be handled on site.  The development will also create 100% of its energy on site through self-sustaining energy generation and distribution systems.

The kicker…this is a 200,000 sf facility.

Now think about your water usage and the amount of water run off at your home.  Say your home is 4,000 sf.  This development will deal with 50 times the amount of water that you are.  It is mind boggling yet undeniably inspiring that the developers and investors involved decided to pursue sustainability on this level.  If they have the dedication to a more conscientious way of living, think about what we could accomplish in our own small spheres.

EASY STEPS TO SUSTAINABILITY

1.Grow your own vegetables: Even if all you have is a balcony you can achieve tomatoes, green beans, cucumbers, herbs…

2.Frequent your farmers market and begin to buy local.

3.Use a rain barrel to water your garden.

4.Bring bags to the grocery store and everywhere else:  I see so many folks bring reusable bags to the grocery store but rarely at places like Target, Walmart and other stores they could be used.

5.Embrace thrifting: The ultimate in reduce, reuse and recycle.
