How to Manage Pests

Pests in Gardens and Landscapes

Hackberry dieback

Hackberry dieback has been reported only on Celtis sinensis and occurs at least around Davis, California. Symptoms resemble those of a vascular wilt disease. Foliage turns brown or yellow and is undersized or sparse. Limbs die back. Vascular tissue may be dark and stained. The entire tree may die. Hackberry dieback is caused by an unexplained malady.

Solutions

Provide appropriate cultural care and a good growing environment, especially adequate drainage. Avoid excess irrigation. Where the problem occurs, minimize spread by sterilizing tools after working on each tree.
