Witches Broom
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
