|This tree in Detroit retained its original trunk.|
What I don't see in my rounds is any recent damage from the borer. The trees that were never trimmed of deadwood can be returned to respectability by the judicious use of a chain saw. There may be a problem that the sprouts are weekly attached to the roots or parent trunk and will fail under load as they get heavier, but this we'll have to discover as the trees develop.
This is not to suggest that one should discontinue treatments of important landscape specimens. It's just not known what the future will bring.
