Oak galls?

Asked October 29, 2019, 8:50 AM EDT

Please see the attached photos. These were found on some fairly young oaks in Annapolis. Can you identify and recommend treatment?

This looks like a type of gall, a hedgehog gall made by a gall wasp. They are harmless to the tree. No control is necessary. Here is our website on galls http://extension.umd.edu/hgic/shade-tree-galls
