I have a large stand of Leyland cyprus, 50-60' tall screening my yard on one side. A huge elm tree shaded the bottom 1/2 of eight of the trees and the branchs died from the ground, up to 30' up the trunk. The tops appear healthy. The shading elm is gone and on the advice of a tree specialist, I trimmed off most of the dead branches. It's been six months now, yet even with the application of evergreen fertilzer and plenty of water, no new branches have grown on the lower part of the trees.
Will these trees recover? How long should I wait before removing them?
