Injections - Oaks and Elms

Oak wilt and Dutch elm disease are diseases that are fatal to thousands of trees across the metro every year. Management has two essential components - treating healthy or newly infected trees by injection, and the removal of diseased trees and wood. Injections can only be done from June through September. The removal of diseased elms should be done as soon as possible. Diseased oak trees are to be removed during dormancy. Never prune oaks during the growing season.
