The ash tree in front of my home has been declining rapidly. A few of the top limbs are now bare. The stress sprouts are re-growing. I had pruned them a couple weeks ago to remove them.
Today I checked for “D” holes to see if the female adult ash borer had left yet and I found quite a few such holes around the trunk.
Now based on what I’ve read, the larvae, from the female’s eggs, will begin to make their tunnels as they feed under the bark.
