Gardening in Sand
Till a 6-inch layer of compost tnto your soil several weeks before planting to greatly improve its fertility. Or, build a raised bed and fill it with a combination of purchased topsoil and compost. Mulch plants with organic matter, such as compost, shredded bark, grass clippings, or straw. Continue to add lots of organic matter each year, which over time will not only improve your soil's fertility and drainage, but will also increase its ability to retain moisture and nutrients. Organic matter also provides food for earthworms and microorganisms that help build the soil.
