It is best to water your lawn as deeply and infrequently as possible. Turfgrass should be allowed to dry out to the point at which it begins showing signs of stress. These signs include wilting, turf turning a greyish purple color, lack of resiliency and more.
When you do water your lawn, apply the water to your turf as deeply into the profile as possible when you see signs of wilting. This infrequent routine will help develop a healthy, resilient Turfgrass system!
