Remove thatch from turf. A thick-thatch layer restricts the movement of water into the soil.
Increase mowing height of lawns to allow plants to develop deeper root systems.
Keep the lawn mower blade sharp. Sharp mower blades make cleaner cuts that cause less water loss than cuts from dull blades.
Control all weeds. Weeds use water that would otherwise be available for desirable plants.
Reduce the number of fertilizer applications. Fertilizer promotes plant growth, increasing the need for water.
Prune. If the water supply is so limited that plant survival is uncertain, substantial pruning can be done at the peak of a water shortage.
Apply wetting agents to the soil to allow it to absorb water uniformly and to prevent dry spots.
Use 2-3 inches of mulch on entire beds of shrubs, trees, annuals and perennials.
Extend the number of days or weeks between water applications to the longest suitable interval.
Soak deeply.
Cull plants that are growing poorly. Don't waste water caring for marginal or undesirable plants.
Use wastewater free of harmful compounds (e.g., borax and trisodium phosphate).
Adjust sprinklers to avoid spraying water on sidewalks and streets or into gutters.
Keep sprinkler heads clean to ensure uniform water distribution.
Check the hose and faucet washers annually, replacing them when worn.
