How to Manage Pests

Pests in Gardens and Landscapes

Nonparasitic gall

Nonparasitic galls are globular galls that occur on branches. Galls may be several inches in diameter. Tree vigor is not seriously affected. Nonparasitic galling may be a genetic disorder.

Solutions

There is no control other than eliminating the tree.
