Destroy Infected Red Oaks

Know What To Do With Infected Trees

Red oaks killed by oak wilt should be cut and burned, buried or chipped to prevent the formation of fungal mats. The city's Diseased Tree Ordinance states that red oaks dying or dead from oak wilt must be cut and the wood destroyed within three days.

Spanish oaks infected in late summer or fall are most likely to produce fungal mats the following spring. Red oaks that die in late spring and summer often don't form mats due to the hot, dry weather. If you suspect that a red oak may have oak wilt, please call the City Forester as soon as possible.
