I planted impatiens on Memorial Day and they were doing well until a few days ago when they started developing brownish spots on the leaves and began to die. They are planted in 2 separate locations. Could you please tell me what happened?

Sounds like your impatiens have a fungal disease commonly called leaf spot. It's carried by insects, usually thrips, and there's no guaranteed treatment. You can try an all purpose fungicide, but your best bet may be to pull and destraoy the plants. Sorry.
