Witches Broom

Characterized by odd-looking clusters of intense growth, shoots infected with witches' broom grow out of lateral buds on branches in the vague pattern of a broom.




A prolific broom infection has the potential to pop up all over the tree, destroying it in some cases. Trees are susceptible to infection by witches' broom at vulnerable points such as where pruning or injury has taken place.


Prune and destroy brooms and injured branches. Spray the affected tree with locally recommended fungicides in fall or early spring.
