Witches broom is a symptom of woody plants where compact clusters of numerous twigs and branches are formed. The mass of shoots comes from a common point, giving a broom-like appearance. The witches broom may last several years. Although some people consider witches broom unsightly, serious injury seldom results.
Witches brooms can be caused by various sources including mites, viruses, fungi, mistletoes, insects, and nematodes. Knowing the type of host plant can help determine the cause of the witches broom.

 

Description of the Symptom

Identifying the symptom: Witches broom is easily identified as a dense cluster of twigs growing from a central source. Witches broom is easiest to see when there are no leaves on the trees.
Susceptible trees: Most trees can show signs of witches broom.
