I have six leyland trees planted last year about 4' tall. Deer have been chewing their top portion. As a result of this the top is completely bold. Can I cut this leading branch? Or how can I make sure they are able to grow healthy? Thank you
I would just cut off the tops and prune them lightly just to make them presentable. This spring give them some fertilizer either as directed by a soil test (www.soiltest.uconn.edu) or follow the directions of the fertilizer package. Next year you might want to consider deer fencing - you still may want to this year if the deer keep coming back.
