These plants, although drought tolerant, will still need some water to stay alive during extended drought. Trees and shrubs will need regular watering during their first year in the landscape to establish a good root system. The annuals and perennials listed will survive drought conditions but they will not produce new flowers.

Most drought tolerant plants need good drainage to prevent root rot. Soil drainage can be improved by "tilling in" organic matter and the use of raised beds.

For efficient water use, group plants with similar water and environmental needs into beds.

Drip irrigations systems can provide up to 95% water use efficiency compared to 50% for sprinkler systems during hot, windy days.

The use of approximately 3 inches of plant based mulch will greatly reduce soil surface evaporation and cool the plant's roots improving root growth and overall plant health.
