Why Do Chinese Kousa Dogwood Tree Leaves Fold In Half

Question From: Hamburg, Pennsylvania, United States
Q: Why do the leaves on my Chinese Kousa dogwood tree fold in half? They fold down the center of the leaf.

A: The leaves of young trees planted in sun curl in hot dry weather because they cannot move moisture fast enough. It should grow out of this habit in a few years. Best And Happy Yardening, Nancy
