Common plant problems in the Atlanta area
PESTS, PROBLEMS & SOLUTIONS
Atlanta’s growing season provides plants with almost year around growth. Because of this long growing season pest populations can build to thresholds where plant damage can occur. The natural and man-manipulated environment in Atlanta can also cause stress and eventual decline in our landscapes and forests. The following is a list of some of the more common pests, cultural problems and environmental problems we may encounter year to year.

Jumping Oak Gall

The jumping oak gall (Neuroterus sp.) is caused by a small stingless wasp.  The female wasp lays eggs in developing leaf buds. The egg hatches into a larva that will live in and feed on the gall tissue. In early summer, the gall drops from the leaf and moves into leaf litter or the soil. The larva will mature into a pupa and overwinter in the gall

 

Damage may be severe for one or two years and then the population declines as natural controls become effective. White oaks and other oaks in the white oak group are the host species. Although infected trees may be defoliated, the problem is rarely fatal for healthy trees.

 

There is no effective treatment for this gall and treatment is not necessary.
