To reduce evaporation and interference from wind.  You’ll save 20-25 gallons per day

Use the Cycle and Soak Method

Based on the watering schedule recommended by the Watering Calculator, take half of the suggested watering time for each cycle, and soak in between the two cycles. For example, if the watering calculator recommends 4 minutes of watering, water your lawn for 2 minutes, wait an hour, and then water another 2 minutes.
