Knowing when to water your lawn can make all the difference. Weather, soil, and the type of grass you have influence the amount and frequency of watering required. Your lawn will show signs of needing water. The grass foliage will start to turna dull gray when it needs water. You can also check your footprints as you walk across the lawn. If the grass pops back up, then your grass is in good shape. If the footprints remain compressed for a while, then it's time to water.
Water your lawn thoroughly but infrequently to grow a healthy lawn with deep roots. Light, frequent watering will leave your lawn with a weakened root system and more susceptible to heat and drought.
Early monring is the optimum time for watering your lawn. Watering your lawn in the evening can cause a greater chance for disease problems.
