Description

Galls are abnormal growths on plants. They are caused by the feeding of living organisms, including bacteria, fungi, nematodes, mites and insects, on the affected plants. Although growths may disfigure twigs and foliage, they usually do not affect the health or vigor of the host plant. Horned and gouty oak galls, however, can cause serious injury to oaks.
