As California enters another dry summer, the supply and use of water are once again becoming topics of immediate concern. Statewide, agriculture dominates use of developed water — meaning water which is moved through pipes at some point. In urban areas, about half of developed water is used outdoors, and of that fraction about half is used for landscape irrigation. That half is an important fraction in Los Angeles and other urban areas. Across the state, homeowners may be interested in saving money on water bills, improving plant health, limiting weeds, and being ecologically responsible while still having an attractive, low-maintenance landscape.
