Don't overwater your lawn. As a general rule, lawns only need watering every 5 to 7 days in the summer and every 10 to 14 days in the winter. A hearty rain eliminates the need for watering for as long as two weeks. Plant it smart, Xeriscape. Xeriscape landscaping is a great way to design, install and maintain both your plantings and irrigation system that will save you time, money and water.
Water lawns during the early morning hours when temperatures and wind speed are the lowest.
This reduces losses from evaporation. Don't water your street, driveway or sidewalk. Install sprinklers that are the most water-efficient for each use. Micro and drip irrigation and soaker hoses are examples of water-efficient methods of irrigation. Regularly check sprinkler systems and timing devices to be sure they are operating properly.
