Lawrence said a jumping oak gall outbreak can last for up to two years, then natural controls, such as weather and parasitism, will help lower the population numbers.

Tree-care basics include mulching around trees, avoiding root damage and damage to bark from lawn mowers and string trimmers. Watering will be essential to help white oaks recover from jumping oak gall infestation.
