If you live anywhere in the Midwestern United States, it is not a matter of “if” your ash trees will be infested by Emerald Ash Borer, it is a matter of “when.” You may think that is a scare tactic and you know what guys; it is!

I have been working in the lawn and landscape industry for the past 21 years and outside of the Asian Longhorned Beetle infestation in the early 2000s, the threat the Emerald Ash Borer beetle poses is the most serious I have ever seen. And, like its name implies, the Emerald Ash Borer (EAB) attacks ash trees. Guess what the most planted parkway tree in established neighborhoods throughout the Midwest is? … yep, the ash tree.

Is There Hope?

Well of course there is! For every bug, insect or pest that the devil creates, we horticulture folks have a way to eradicate it. In fact, in the case of the emerald ash borer, we have some very reliable preventatives that will save your trees from certain infestation and death.

Ash Tree bark is very rough in mature trees.

Many ash will have green lichens (a fungus) growing on their trunks as well.

Lichens do not hurt the tree in any way.
