Figured this might be a good place to post this. I have a Rose of Sharon on my deck that is covered with some sort of pest. It looks like small black spots all over the flower buds and now on some leaves as well. I noticed today that there are a bunch of little insects on the leaves too which makes me believe that the black spots are eggs of some sort. Anyone know what this is and how to treat it? It's in a large pot and before the freeze I have to bring it into my house and don't want to bring those bugs in with it. Thanks in advance!
