What is ash flower gall?
Galls are abnormal plant growth that can be caused by insects, mites or plant diseases. On ash trees, a tiny eriophyid mite causes male flowers to grow into round greenish, 1∕2 to 1 inch diameter tumor-like structure. Sometimes the lumpy growths also cause leaf distortions.
