I have two Purple Mountain Ash that my Dad helped me plant years ago. Little buggers got into mine
about six years ago, looked like someone was using the tree for shotgun practice. Read about a chemical
that they inject under the bark called "Tree-age" Systemic Insecticide. Kills the little buggars as soon
as they start to burrow under the bark. Had both trees injected right away at a cost of $150.00/ tree.
The crowns are fine, and as long as I keep having them injected every two years, they should be fine.
The chemical lasts two years, and when all of the ash borers move west with no more "Food", I can stop injecting them.
