Soils are clay and alkaline.
Often there is an expansive layer of caliche, a solid rock, just below the surface. The wind blows hard almost constantly, and the sun is hot and strong. For these reasons, it is easiest, for landscaping purposes, to grow native plants or others that are suitable for this harsh environment. All plants need water and protection when newly planted, but once they are established, they will tolerate poor desert conditions. All should, however, be watered deeply in a severe drought, even in winter.
