If installed during Summer: Water new sod daily for the first three weeks. Thereafter water twice weekly for a few weeks. Finally, water once a week with one full inch (1″) of water during the season. When the weather is very hot or very dry, return to the twice weekly schedule. If installed during Spring or Fall: Water daily but don’t let it remain soggy and soft. If cool and rainy, water two or three times weekly, until the grass is established, which takes about 2 to 3 weeks. Set the sprinkler to this schedule… do not water daily after the grass is established. Stop watering in early October.
