1. Choose native plants.
Native plants have had eons to adjust to the area’s normal rainfall, soil, and climate. Once established, they require little or no watering. Start your research on native plants at your local cooperative extension or botanical garden.
Websites such as eNature.com or H2ouse.org can help you find the best species for your location. You could also use a handy database of nurseries nationwide that specialize in native plants.
