Watering the Lawn

Watering your lawn is very important, especially during extremely hot or dry weather. Experts recommend giving your lawn an inch of water per week during the growing season (March to September) and more during the hot and dry spells. Additionally, watering is necessary during especially warm or dry winters. Here is a good test of whether you have watered your lawn adequately: Push the blade of a screwdriver into the ground. You should be able to easily sink three to four inches of the screwdriver immediately after watering the lawn.

The Georgia Water Conservation Plan specifies that even-numbered homes water on Mondays, Wednesdays, and Saturdays and that odd-numbered homes water on Tuesdays, Thursdays, and Sundays. The best time to water your lawn is between 4 and 6 AM. Because a wet lawn is more susceptible to disease, you should take care to limit the lawn’s “wet period.” The wet period is the time from when dew first forms on the lawn until when the lawn is dry. If you water in the evening, before dew forms, you will extend the wet period and encourage disease. Additionally, because of rapid evaporation and wind, you should not water the lawn in the middle of the day.

To encourage the lawn to develop a deep root system, it is better to use more water fewer times per week than to use many short watering sessions. However, if too much water is applied at one time, the excess water is wasted as it runs off the lawn and into the street. To maximize the amount of water absorbed and not wasted, you will need to vary the length of time the sprinkler system operates in each area and observe the runoff.
