How To Lay Down Sod Patch. You’ll want your sod to rest about an inch below any hardscapes like walkways or sidewalks, so take that into consideration as you grade your surface. The best time to water new sod is in the mornings.
Till the soil to a depth of 6 to 8 inches using a tiller. This will help remove roots. Pat sod carefully into place, so there aren’t any air pockets between soil and sod.
To install sod on an existing lawn, cut any existing grass low, and level out any holes or step dips in the yard.
Select the right type of grass for your area, usually it’s kentucky bluegrass. Unroll one piece at a time, end to end, and avoid walking on pieces of sod as you're laying new ones down. Purchase fresh sod or have it delivered. Lay your new roll of sod over the top of the area to be patched.
