The Water-Wise Garden: Art of Xeriscaping
Xeriscaping requires very little water, provides wildlife habitat, reduces chemical pollution—and saves you money.

When I moved from the dry foothills of Colorado to humid North Carolina, I expected water to be abundant and flowers to bloom all year. I planted a container garden on my back porch in the spring, and by August—after a string of weeks reaching 110 to 120 degrees with no rain—my shallow-rooted plants were dead. The Southeast was in a severe drought, and I realized it was time to brush up on all the water wisdom—especially xeriscaping—I learned while living in the arid West.

"Xeriscape" derives from the Greek xeros, which means "dry," and describes a method of low-water landscaping. Coined in Denver during an early 1980s drought, the term is often misinterpreted as "zeroscape." Popular in the Southwest, xeriscaping has now spread across the country: All 50 states have active programs. In some areas with extreme water shortages, xeriscaping is mandatory; other regions are adapting the principles to mitigate potential drought problems before they arise.
Xeriscaping is gaining popularity as more communities become interested in conservation. To reduce your own garden’s water needs, just remember these seven principles:
1. Plan. Walk around at different times of day and get to know the different conditions in your yard: natural contours, exposure, drainage patterns, soil types. You’ll typically find three zones:
Protected areas: Areas that are protected from the sun and wind and require little irrigation once established. Often found along north- and east-facing lands, these areas are best for plants that require the most water.
Partially exposed areas: Areas that have limited protection from the elements and require slightly more water. Best for plants with moderate water needs.
Exposed areas: Often located along dry, west- and south-facing land, these areas require significant irrigation. Strictly xeric, or low-water plants, are best here. Plant the species that require the least water in the least protected areas. Once you know your yard’s zones, you can plant in appropriate areas, grouping plants with similar needs together and allocating water more efficiently.
2. Prepare your soil. Break up tough, compacted soil and add organic materials such as compost and pine bark, as well as any nutrients your soil may be missing. Aerate the top 6 to 8 inches of soil, then add organic topsoil. Your drought-tolerant plants must be able to develop deep roots so they’re less vulnerable and don’t depend on superficial moisture.
