As a general rule, most lawns require about one inch of water per week from rain or sprinkling. But many people ask, "How long should I water to equal one inch?" Well, it depends on your water pressure and the type of sprinkler you choose.
A few tips to keep in mind:
· It's best to water early in the day. You won't waste water through evaporation, and watering at night puts your lawn at risk for developing mildew and fungus disease.
· Don't give your lawn a light sprinkling. This promotes shallow roots, and it may not even reach the soil, depending on how much you water.
· During dry spells or droughts, pay attention to watering restrictions.
· Water deeply and infrequently (1/2" twice a week is enough) and don't waste water.
