Cherry Leaf Galls: Harmless Bumps Caused by Insects

Bumps on cherry leaves are galls—insect-induced growths. Aphids, mites, wasps, or midges lay eggs; plant tissue swells around them. Each insect makes a characteristic gall shape. Galls don’t harm tree health.

Common Gall Types

Mite galls: Tiny, felt-like patches (often on cherry).
Aphid galls: Pouch-like folds.
Wasp galls: Hard, woody spheres.

No treatment needed. Insecticide won’t help once galls form.
