Can half-dead ornamental purple plum tree be saved?
In our co-op complex, nearly every yard has one of those small ornamental purple plum trees in it. The ones which are not anywhere near the taller oak trees are doing fine and are thickly leaved. The ones (such as in my yard) which have large oaks living next to them have half their branches dead and bare. I have asked the mgt. to prune them and they won't, for some dumb reason. Could pruning away the dead branches help save these trees?
