How should I water a newly sodded lawn?
A newly sodded lawn should be watered once or twice a day for the first 7 to 10 days. Apply enough water to moisten the sod and upper 1 inch of soil. The sod should root to the soil in about 10 days. At this point, gradually reduce the frequency of watering, but water more deeply. After the sod has been mowed 3 or 4 times, a deep watering once a week should be adequate.
