Asked May 31, 2024, 9:18 AM EDT

This growth appears on a single branch of a small walnut tree. Is this a problem, and if so, is there a remedy?

Expert Response

That appears to be a type of gall. Galls are abnormal tissue swellings that can be caused by various insects but are do not harm the trees.
