Rock yards and cactus are not the only solutions to a water-wise landscape. Managing the amount of water used is also a factor. Most of Arizona receives very little rain each year; therefore people rely on municipal water for landscape plants and gardens. Selecting low water-use plants is important but managing what little rain falls can make a difference, too.
Rainwater harvesting is the process of catching and storing rain or creating a path for the water to find its way to trees, plants, or gardens. Watch how water flows on a property during a rainstorm. Direct it into storage barrels or cisterns with gutters and use it later. Slow the flow on hills or slopes by creating a slight ditch (or row) on contour to prevent soil erosion as well as allow the water time to settle into the soil.
When it rains automatic irrigation systems can be turned off, even if it is just for a day or two! Rain stored in barrels can be used as needed over a period of weeks or months depending on the quantity stored. Properly managed and stored rainwater in the desert can make a difference in an arid environment.
