I planted a maple in December and this spring it began to bloom. The top 6 inches on 5 separate branches of the tree are dead. The leafs on the very low branches are small and the leafs at the top near the dead part of the tree are 3 times the size of the leafs on the lower branches. Can you tell me what is going on with my tree. What can I do? Can I trim the dead part off the tree. I have been told that trimming the top of young trees is a bad thing. Thanks Brandy :)
