The most common reason new sod fails is not enough water in the first two weeks. Until the roots grow down into your soil, the sod is living on whatever water you give it.
Weeks one and two
Clemson Extension recommends watering new sod with about 0.2 inches of water every day for 10 to 14 days, and says the best practice is to split that into two waterings of about 0.1 inches each (Clemson HGIC, Watering Lawns). Early morning and early afternoon work well.
Water every zone, every time. Corners, edges and spots near the driveway dry out first.
After that
Once the roots take hold, cut back gradually to once or twice a week, depending on your soil (Clemson HGIC, Watering Lawns). Clay holds water longer than sandy soil, so clay yards usually need less frequent watering once the lawn is established.
How to tell if it is working
- Gently lift a corner of the sod after about a week. If it resists, the roots are growing.
- Gray or curling edges mean it needs more water.
- Puddles or a squishy feel mean it is getting too much.
Before the first mow
NC State Extension suggests mowing once the grass is about 50 percent taller than the height you want, for example cutting tall fescue back to 3 inches when it reaches about 4.5 inches (NC State Extension Gardener Handbook).
