of oak wilt?
As soon as any symptoms are spotted, it’s important to act. Tree

oak wilt can also be transmitted via insects, which means that homeowners
should not prune during the growing season. Immediately calling a tree disease
professional after identifying a symptom of oak wilt is the best way to protect
all of your trees.
