How to grow greener grass magic bullet # 1. Water deeply, but not often
Water for 30 minutes. Then plunge a spade into the soil and pry out a wedge to see how far the water has penetrated. Four to 6 in. deep is ideal. Not deep enough? Water longer. Once you know how long to water, use a water timer and you'll know what to set it for every time.
Heavy soils should be watered less often and less heavily but for longer periods of time. Sandy soils, on the other hand, can handle heavy, fast watering but dry out faster. In hot, dry weather, you may have to water every two to three days.
