Answer: It's a tough situation for your impatiens! If you're set on impatiens, I suggest that you remove the plants, mix bagged topsoil or compost into the top couple inches of soil, replant the impatiens in the soil, and replace the mulch. Provide shade for the plants for a week or so while they get settled in and start showing new growth. Alternately, you can grow some different annuals that can take the heat and sun, such as coreopsis or daisies, or interplant so the other annuals will provide some shade for the impatiens. I hope this helps!
