Tricolor Beech Leaf Curl: Aphids, Leaf Scorch, or Sun Reaction?

Three Possibilities

Aphids on new growth cause curling. Test: tap branch over white paper.
Leaf scorch (bacterial) via leafhoppers—usually broader leaf damage.
Sun/heat stress on tender new growth—temporary, not harmful.

Recommended Action

Apply Bayer Advanced Tree & Shrub Insect Control (imidacloprid soil drench) as insurance against aphids/leafhoppers.
Monitor new growth—if curl persists without pests, it's environmental.
