Little black insects on my Proven Winners petunias
Hello! I have two hanging baskets on my front porch that have three Proven Winners Supertunias (bubblegum, silverberry, and raspberry colors). THey are doing well, but I noticed yesterday that there are tiny black insects on the petals. At first, I thought it was specks of soil...that's exactly what it looks like. But I'm sure they are some kind of bug.
I've dealt with this before, but the insects were white. What should I do? The insects that were white killed my Supertunias last year because I let it go too long and didn't deal with the problem.
I spent too much on these plants (and they are doing too well!) to let them die! What should I use?
ps - I'll post pictures if needed.
