Parts of two adjoining roses out of my total of 72 had areas of quite abnormal growth that i pruned out yesrerday. Today I fished some out of mixed organics long enough to take a photo, which is attached. The two stems are from roses of very different sizes. Is this rose rosette virus? If not, what could it be? If it is, is my only recourse,the careful and hygienic entire removal of both roses?
