Halloween is this week, so we figured it's the right time to share this large-scale example of the condition called "Witches' Broom" we found near Lake Quinault last August. Witches' Broom is a condition where a cluster of branches all grow from the same place on a branch. It can be caused by multiple factors such as fungus, phytoplasmas, mites, or genetic mutations. If you don't like the way they look, these limbs can be pruned out. Consult your arborist for proper pruning techniques!
