Q: Our London Plane Tree is loosing its leaves only off the top. We planted these tress 2 years ago and they seemed to be doing fine. However we noticed the leaves are falling off the top branches only and it doesn't seem to be getting any new buds.
Julie, There could be many reasons for your tree's problems. My guess would be lack of water. However, if it were my tree I would get an onsite inspection from a tree doctor, a certified arborist, because a bad guess could result in the death of the tree. Best And Happy Yardening, Nancy.
