Disease in Impatiens
I have been planting impatiens in the same spot for 5 years and they've always done great. I just noticed that there aren't near as many blooms all of a sudden, and when I looked more closely I see black spots on many of the leaves as if they're diseased. What is this and can anything be done this late in the season. ?

It sounds like they have black spot or a related fungus. Treat them with a fungicide and this should clear it up.
