A healthy lawn can prosper with one inch of water per week. In extremely hot and dry climates, you may need to water more. If your footprints remain visible in the grass when you walk across your lawn, or if your grass turns a bluish or dusty green it is time to water.
It is better to water deeply once a week than to water a small amount several times a week. By watering deeply and thoroughly, you encourage a deeper root system in your lawn. A deeper root system will have access to more water and nutrients than a shallow root system.
Automatic watering systems save time and water and will, in the long run, give you a healthier lawn. By setting the timer for the exact length of time that your grass needs watering, you will never have to worry about running off and forgetting that you left the sprinkler running.
