Early morning and only for about 20 minutes.


Our soil in CA is too clayey for an hour's worth of watering-- you'd just be wasting it, and since there's a drought, you'd be using more water than you should, anyway!It's summer-90+ degree weather, need advice on how long to water my lawn %26amp; when?
exactly how long to water depends on your sprinklers. Your lawn needs an inch to an inch and a half of water per week. Also when watering it is best to water for longer then to break it up into several short waterings. Watering deeply helps the grass develop a deeper root system. Also water early in the morning as this will allow the grass to dry out and you won't end up with fungus. This is also the time when wind speed is at its minimum and water capacity is at its maximum.





Divide your yard into zones give each zone one hour of water. Then allow a day or two in between waterings to let the grass dry out.
do it early in the morning,for a few minutes
