I planted 15 leyland cypress trees across the front of my property two years ago. At the time of planting the trees were about three feet tall. Last year I found three of my tree centers were all bald and stripped looking. My dad said it was from deer eating the needles off. I did cut the centers out of the trees at the beginning of spring this year. The rest of trees are continuing to grow but no new center has emerged. Am I fighting the inevitable? Will the center ever come back or should I replace these trees?
