Daytime Watering. The best time of day to water your lawn is when air temperatures are lower and there is dew on the ground. Temperatures are usually at their lowest during the late evening or early morning. Most lawns benefit from watering two to three times per week.
The best time to water is early morning, when the sun starts to rise. You lose some water to evaporation in the middle of the day. And watering at night leaves the grass wet too long, which can cause fungus and other diseases in the summer. Give your lawn 3/8 in. of water three times a week. Calculate the amount of time it takes your sprinkler to dispense that much water (Photo 5). Set a timer (sold at home centers and lawn and garden centers) on your hose spigot so you won't have to watch the clock (Photo 6).
