It is essential to begin watering new sod within a half hour after it is laid on the soil. Apply at least 1 inch of water so that the soil beneath the turf is very wet. Ideally, the soil 3 to 4 inches below the surface will be moist. After watering, simply lift up a corner of the sod and check the soil underneath for moisture.
Make sure you keep an eye on your grass every day during this first week. If an area starts to turn brown, it’s most likely not getting enough water. Brown grass does not mean the grass is dead, it only indicates that the leaves have died. If you catch this early enough and adjust the amount of water to that area you’ll likely see new green leaves emerge in seven to ten days.
WEEKS TWO & THREE
Keep the below-turf soil surface moist with daily (or more frequent) watering of approximately 20-30 minutes* or 1/4 inch each watering cycle. Especially hot, dry or windy periods will necessitate increased watering amounts and frequency. Learn to recognize signs of dry turf such as wilted leaves or needle-like appearances and water immediately if this occurs.
If you plant during the summer months, your sod’s probably going to need more water than sod planted in April. On the contrary, if a rainstorm soaks your lawn one evening, you probably don’t need to water it the next morning.
Avoid prolonged periods of standing water in any area of the lawn. Overwatering can prevent the sod from rooting and prove just as damaging as not watering at all. Monitoring your lawn closely will allow you to correctly assess the amount of water needed.
