- Oaks and Elms
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.
