When watering your lawn, wet the soil to a 3-4 inch depth. Normally this should create enough reserve moisture in the soil that you will not need to water again for several days depending on rainfall amounts. It’s best to water an established lawn heavily and infrequently to promote healthy root growth. The most common mistake homeowners make with watering is applying water lightly, daily. This can lead to shallow rooting and disease problems. You can determine soil moisture depth by taking a screw driver and pushing it into the soil. If you meet little resistance, then the soil is wet. However, if it doesn’t push easily into the soil, then additional water is needed. Your lawn needs a minimum of 1.5 inches of water weekly. Early morning is the best time to water. If your lawn appears to be stressed or showing signs of dormancy, raise the deck height of your mower.
