First 10–14 days
Water new sod while it establishes
A clock alone cannot tell you whether new sod is wet enough. Heat, wind, sprinkler output, soil and exposure all change the runtime. Verify moisture at the soil.
Water immediately
Apply enough water after installation to move through the sod and thoroughly wet the soil below it. Water installed sections as the job progresses rather than waiting for the entire yard on a hot day.
Check beneath the sod
Lift corners in several sun and shade locations. The underlying soil should be moist. Dry soil means water has not reached the new roots; standing water or a spongy saturated site means the application is excessive.
Keep it moist, not saturated
USU recommends maintaining moist soil for about 10–14 days while roots establish. Frequency may change across the site and with daily weather. Fix runoff, pooling and sprinkler gaps instead of compensating blindly.
Protect the root zone
Avoid foot traffic and equipment while the sod is wet and shallow-rooted. Keep exposed edges from drying faster than the center of the lawn.
Test for rooting
After the establishment period, tug gently in several areas. Resistance indicates roots are knitting into the soil. Do not reduce irrigation based on the calendar alone if the sod still lifts easily.
Transition gradually
Move away from frequent establishment watering toward deeper, less frequent irrigation as rooting allows. Use current local guidance for established grass and adjust for grass type, soil and season.
Sources & useful tools
Use current local restrictions and the instructions that come with your order when they are more specific.
