Sod Installation

The Preparation is one of the most important aspects

New sod can transform a yard overnight — but that instant "wow" only holds up if the ground underneath is ready for it. Sod is not a fix for a bad lawn foundation; it's a finishing touch on top of good prep work.

Clear Out the Old Lawn and Debris

Start with a clean slate. Remove any existing grass, weeds, roots, rocks, and construction debris from the area. This can be done by:

Sod cutting – physically stripping the old turf and roots away
Herbicide + removal – killing off existing growth, then raking it out once dead
Tilling under – only recommended for smaller areas, since it can leave old roots and weed seeds mixed into the new soil

Whatever method you use, the goal is the same: no old grass, weeds, or large debris competing with or blocking the new sod's root system.

Test and Amend the Soil

Healthy sod needs healthy soil underneath it. A simple soil test will tell you the pH and nutrient levels you're working with. Most turfgrass wants a pH between 6.0 and 7.0.

Based on the results, you may need to:

Add lime to raise pH (common in more acidic soils)
Add sulfur to lower pH
Work in compost or topsoil to improve poor, compacted, or sandy soil

This is also the point to till in a starter fertilizer if your soil test shows low phosphorus, since phosphorus is critical for root establishment early on.

Grade the Yard

Proper grading isn't just about looks — it's about drainage. Water should flow away from the house's foundation, not pool up in low spots.

Aim for a gentle slope, generally around a 2% grade away from structures
Fill in low spots and level high spots with quality topsoil
Rake the area smooth after grading, breaking up any large clumps of dirt

Uneven ground under sod leads to uneven mowing later, plus soggy or dry patches depending on how water settles.

Till, Rake and Roll

Compacted soil is one of the biggest enemies of new sod. If the ground has been sitting bare, driven on, or walked over regularly, it's likely compacted and won't let roots push down easily.

Till the top soil
Break up clumps so the surface is loose and workable
Remove any rocks or debris that surface during tilling
Rake the area one final time to create a smooth, even surface
Lightly water the soil the day before installation so it's moist (not soaked) when the sod is laid
Some pros run a lawn roller over the loosened soil to firm it up slightly without recompacting it — this helps avoid sod settling unevenly after installation

Lay the Sod Promptly

Once the ground is prepped, don't let it sit too long — freshly graded and loosened soil can dry out, get rained on, or invite weeds. Have your sod delivery timed so it goes down within a day of finishing prep, and lay it the same day it arrives whenever possible, since sod is a perishable product. You do not have to but Rerolling right after the sod is laid (before you water) will help make sure there is good ground contact with the roots

The Bottom Line

Sod prep isn't the exciting part of the job — it's the part clients don't see. But it's exactly what separates a lawn that thrives from one that needs to be replaced again in a year. Time spent clearing, testing, grading, and loosening the soil pays for itself in root establishment speed and long-term lawn health.

Get the ground right, and the sod will do the rest.
