Issue with Low Grow Sumac shrubs

Asked August 9, 2018, 6:07 PM EDT

We have Low grow sumac planted last year on a hill to keep erosion down. They have been growing good and leaves are green but on what seems to be the new growth this year, the leaves have little growths or spots on the leaves. Can you tell from the pictures attached what this might be? Someone mentioned it might be Gall, like some maple trees have this year. I need to know if it is and how to treat it. We also put in a few new low grow sumac a couple months ago, and they don't have it on them. Thank you for your help. Roseann

It looks like your sumac has a gall from eriophyid mites. They can vary from year to year and are unsightly but not something that you need to worry about or treat. Here is more info about galls.
