Aphids invaded my beautiful new hanging basket. I sprayed it and they are gone. I didn't see many aphids so I thought I treated it in time but after a week the plant still looks horrible. Can this plant be saved? What should I do? Oh, there are 3 colors of calibrochia (sp) plant in the basket but they are so intertwined that I don't believe I could seperate them to replant the other two.I have never had a plant not bounce back after spraying it. Or could it just be this horrible heat we have had all week. I did put the plant in the shade and kept it well watered with fertilizer. Any suggestions.
