My plants have been wintering well in MN. Just went in to check on them and again, there are tiny white specks flying about when I touch them. I believe they are aphids. What's my best approach to get rid of them prior to my being able to get them outdoors? I pruned them quite a lot last fall before I brought them indoors and they've been doing quite well this time. What sprays, bagging, etc. do you recommend?
