Avoid “Set it and Forget it” With Turf Irrigation Systems
With automatic turf irrigation, it is not unusual for the system to be turned on and left on for most of the summer. This practice often leads to water waste and incorrectly watered lawns. The best setting for automatic irrigation systems is manual, allowing property owners to choose when to irrigate.
For turfgrass, maintaining a moist soil to a depth of 4 to 6 inches is better than maintaining a continuously wet soil to a depth of a 2 to 3 of inches. Allowing soil to dry briefly between irrigation has benefits, such as recharging soil oxygen that plant roots need as much as water to grow and function well.
