Rugosa Rose

Asked May 23, 2019, 11:45 AM EDT

My rugosa became infected with these balls two summers ago. What are they and how do I get rid of them? I tried to prune them out, but they came back. Thanks.

Hello,

Thank you for your question.

I checked with a rose expert and here is the response....."They’re galls. Prune the branch several inches below the gall and discard. Disinfect pruners. Rugosa can be pruned way back and come back."

Hope this helps.
