I had purchased these hanging baskets beginning of June to hang on my front porch. They are about 6 feet apart and one of the planters is doing amazing and the other is not doing so well. I can not see any visible bugs anywhere.on the plants, they get the same amount of sun, water etc. The hanging green stuff is going great it seems to only have affected the impatiens and coleus. Anything I can do to make it come back?
