Sod requires a great deal more water because it is already established turf with a root zone that is only ½” to 1” thick. Keep sod wet but not saturated until sod has rooted to the existing soil. You can easily tell when you can no longer lift the sod off the ground.
Example: Weeks 1-2 water 3 times a day 30-40 minutes every day. Weeks 3-4 water 3 times a day every other day at 25 minutes a time.
Slit seeded/over seeded lawns require slightly less water as a newly seeded lawn.
Weeks 1-2 water lawn twice a day for 20 minutes.
Weeks 3-4 water lawns 3 days a week 20 minutes
Week 5 water lawn as normal.
