Hickory Tree Loses Its Leaves In Clusters Starting In May

Question From: G. Hines - Hague, New York, United States
Q: I have a hickory tree that loses its leaves in clusters starting in May. This continues all summer. Many of the leaf clusters have cankers.

A: Here's a website that explains some of the issues your tree may have.

If it were mine and I wanted to save it I would get an onsite inspection from a certified arborist. To find one in your area go to www.tcia.org.
Best And Happy Yardening, Nancy
