Well, believe it or not, I have some good news on the rose front. I tried the natural remedy of draping banana skins over the rose bush, and there has been a definite decrease in aphids. They haven't completely gone, but I'm adding more banana skins and we'll see how it goes. It makes me wonder if you could make a spray by blending banana skins with water and if that would also get rid of aphids. Hmmm.
