Galls

About Galls

Abnormal growths commonly found on oak trees and other hardwoods, galls are caused by tiny insects or mites that inject chemicals into plant tissues. These swellings can vary in shape and size, often appearing as round or irregular bumps on leaves, stems, or branches. While generally not harmful to mature trees in Middle Tennessee, including areas like Franklin and Brentwood, heavy infestations may cause aesthetic damage and stress to young or weakened plants.

Galls is a landscape pest commonly found in Middle Tennessee, including Columbia, Thompson's Station, Spring Hill, and the surrounding areas. This entry is part of our Landscape Pests identification guide.

As lawn care and treatment specialists, we encounter Galls regularly when servicing properties across the region. Proper identification is the first step toward effective pest management that protects both your turf and your landscape plantings.
