Q.Do I Treat The Maple That Has Dropped Its Leaves In The Middle And If So, What Treatment? Do I Cut The Limbs Off The Burr Oak Whe
re the leaves stop? I had two maple trees and a burr oak transplanted and moved about three years ago. One of the maples has leaves at the top and the bottom, but the leaves in the middle have fallen off this spring. The burr oak has limbs that have leaves about halfway out and then no leaves the rest of the way out and look dead.
