Watering a Newly-Sodded Lawn
For the first 20 days, water as needed to keep the topsoil moist to a 3-inch depth. Do not allow the lawn to become soggy or let water pond. After 20 days, water three or more times a week during warm weather. In cooler weather, water once or twice a week. Sandy soil requires more frequent watering than clay soil. Inland areas require more water than coastal areas. Special attention should be paid to slopes and mounds where runoff occurs. More frequent, shorter watering may be necessary.
