Just judging from the phone calls to my office, the emerald ash borer is showing itself in my working area of Gahanna, Reynoldsburg, Pickerington and Canal Winchester. As I drive around there are ash trees showing dieback bigtime. Many street trees and legacy trees in front yards are really looking bad with huge parts of the tree without leaves.
At this point we are using a therapeutic insecticide (TreeAge). This material is extremely effective, remains effective at least 2 years and is injected directly into the tree. Also worth noting, with the information we have in hand, treatments are ongoing for the life of the tree. You cannot skip a year.
The point of this post is to treat your ash tree while they still look good. Don’t wait until they show signs of dieback. They will take years to recover from this dieback after treatments. Many people don’t realize they don’t have an ash tree in their yard. It is free to ID the trees in your yard.
