One Oakleaf Hydrangea Has Entire Branches That Are Dying

Question From: Mount Pleasant, South Carolina, United States
Q: One of my Oak. Leaf Hydranges has entire branches that are dying. The leaves just curl up. This has happened very quickly, in a manner of a few days. I have three other plants in the same area, they are all doing fine. Any suggestions? The plants have been in this location for five years and I have had zero problems.

A: Water, water. water. Oakleafs need moisture. Best And Happy Yardening, Nancy
