Leaves Of Well Established Barberry Are Suddenly Drooping

Question From: L. Bergman - St. Louis, Missouri, United States
Q: My older, well established bar berry started great this spring but is suddenly dropping on of leaves. I don't see ant insects. Sometimes my cat hides out under it. What do you think us going on, and what do you recommend?

A: A late season frost may have damaged the leaves. Lack of water will also cause leaf drop. Take a few cutting and leaves to a local independent nursery that sells these shrubs of a more accurate Id. Make sure to keep it well watered and be patient. Do not fertilize it. Best And Happy Yardening, Nancy
