We hope you are enjoying our mild Chicago summer. Even though the weather has been cooler than usual, that doesn’t mean your landscape doesn’t need special care. Here is a photo that illustrates this beautifully:
Here you can see two lines of “Green Ash” trees on opposite sides of a parking lot. So why do those on the left look so much worse than the ones on the right?
Any tree on a parkway, sandwiched between the street and the sidewalk, is at risk as it ages. Its roots are in a ‘soil coffin’ so to speak and unable to freely stretch and grow. Notice the cement coffin the Ash trees on the left are in compared to the Ash on the right. Although those on the right still have a parking lot on one side, they are much farther away from the lot. They are also at least 30 feet away from the building so the roots have a more expansive environment in which to grow.
This stress factor, combined with the constant onslaught from the Emerald Ash Borer, makes it more difficult to save these Ash trees. All of these Ash are under the same degree of Borer infestation but look how much stronger those on the right are…… temporarily. All of these trees, on both sides of the parking lot, will eventually succumb to the EAB without treatment; but obviously those on the left will die a year or two sooner.
Tree Green has had remarkable success treating Ash trees for Emerald Ash Borer. Give us a call, and we’d be happy to give you a free evaluation.
