Frequently asked gardening related questions
Rose gall wasps lay their eggs in rose stems, causing the plant to form a distinctive, often hairy or mossy, green or reddish growth called a rose bedeguar gall (also known as a Robin's Pincushion gall). While unusual looking, these galls generally do not significantly harm the rose plant itself, as the larvae feed harmlessly within the gall. To reduce their numbers, you can prune off and destroy galled stems in late autumn or winter before the adult wasps emerge.
