Lawns only need to be watered every five to seven days in the summer, and every 10 to 14 days in the winter. A heavy rain eliminates the need for watering for up to two weeks. Most of the year, lawns only need one inch of water per week. Buy a rain gauge so that you can better determine when to water. Water in several short sessions rather than one long one in order for your lawn to better absorb moisture.
Water lawns during the designated hours.
Position sprinklers so water lands on the lawn and shrubs and not on paved areas. Check sprinkler systems and timing devices regularly to be sure they operate properly. Raise the lawn mower blade to at least three inches, or to its highest level. A higher cut encourages grass roots to grow deeper, shades the root system, and holds soil moisture. Avoid over fertilizing your lawn.
