Answer: I don't know if you can help them this season but I would surely recommend that you amend the planting bed next season so your plants will thrive. Poor, compacted soils will stunt plant growth. Next spring improve the soil prior to planting. Organic matter in the form of compost, aged manure or even peatmoss dug into the soil to a depth of 6-8 inches will help loosen the soil, allow it to drain well yet hold just the right amount of moisture, and will provide nutrients to the roots of your plants. After working the soil and leveling it, plant your impatiens. I think you will see a huge difference in their performance next year.
