Emerald Ash Borer
I had tree trimmers here last fall to trim some limbs. The head guy informed me that my ash has Emerald Ash Borer. He wanted to take it down right there, but I told him to hold off so I could think about it. The tree had leaves and I didn't notice a problem, but the tree guy saw right away that some branches were bare.
I've been doing some research on the types of treatment. The trunk has a 56" circumference and it's roughly 40 feet high. I'm going to talk to a nursery as well, but wondering if anyone has had experience with this? Can they be saved?
