How to Lay Sod — Step-by-Step Guide
Laying sod is the fastest way to get a beautiful, established lawn. Follow these steps for the best results. Not sure about timing? Check the best time to lay sod in your climate. For region-specific guidance, your local cooperative extension office can provide advice tailored to your soil and climate.
Step 1: Prepare the Soil
Remove all existing grass, weeds, rocks, and debris from the area. Till or loosen the top 4-6 inches of soil. Add topsoil if needed to achieve the proper grade — the soil should slope away from the house at about 1 inch per 4 feet for proper drainage. Rake the surface smooth and remove any large clods or stones.

Step 2: Test and Amend the Soil
Test your soil pH. Most lawn grasses prefer a pH between 6.0 and 7.0. If the pH is too low, add lime. If too high, add sulfur. Apply a starter fertilizer before laying sod to give roots the nutrients they need to establish quickly.
Step 3: Lightly Moisten the Soil
Water the prepared soil lightly before laying sod. The soil should be moist but not muddy. This helps the sod roots make immediate contact with moisture.
Step 4: Lay the First Row
Start along the longest straight edge — a driveway, sidewalk, or property line. Unroll the sod in a straight line, pressing edges firmly against each other without overlapping or leaving gaps. Stagger the joints in each subsequent row, like laying bricks, so the seams do not line up.
Step 5: Trim Around Edges
Use a sharp utility knife to trim sod pieces around curves, flower beds, trees, and sprinkler heads. Cut from the soil side for a cleaner edge.
Step 6: Roll the Sod
After all the sod is laid, roll the entire lawn with a lawn roller (filled about one-third with water) to press the sod roots firmly into contact with the soil below. This eliminates air pockets that can dry out roots.
Step 7: Water Immediately and Thoroughly
Water the new sod within 30 minutes of installation. The first watering should soak through the sod into the underlying soil to a depth of 6 inches. For the first 2 weeks, water daily to keep the sod and soil consistently moist. After 2 weeks, gradually reduce watering frequency while increasing the amount per session to encourage deep root growth.
Common Mistakes When Laying Sod
- Sodding over existing grass or weeds. The old vegetation will die and rot, preventing the new sod from rooting.
- Not staggering the seams. Aligned seams create visible lines and weak spots in the lawn.
- Leaving gaps between pieces. Gaps dry out the edges and create weeds.
- Waiting to water. Sod begins to dry out immediately. Water within 30 minutes of installation.
- Not rolling. Skipping the roller leaves air pockets that prevent root-soil contact.
