SOIL IMPROVEMENTS
Most low water use plants thrive naturally in our desert soils, so amendments such as fertilizers and soil supplements are usually not necessary. They do prefer good drainage, and soil should be loosened at planting time to encourage healthy root growth.
Soil amendments most likely will be needed for turf areas and areas where more water thirsty plants are installed. Because there is quite a variation in soil quality and composition across the Sonoran Desert, soil amendments may be needed when unusual conditions exist.
