I have sandy soil, so my lawn and perennials have not fared well this year with the drought. Whats the best solution?
You’re right, sandy soils do not hold much water. Plants this past season in the East in clay or loamy soils have fared much better. So, short of installing plants that take the drought (see other question), or installing an irrigation system, you can begin improving the soil with organic matter. Small particle organic substances such as shredded leaves, sphagnum peat moss, or compost can be top-dressed (applied around) existing plants or worked into new beds. Be sure and use plenty–several inches a year for several years for really sandy soils (just be sure and don’t bury existing plants!).
