Preparing Red Clay Soil for New Sod in Rock Hill

Graded soil prepared for sod installation

Sod is only as good as the soil under it. A lot of yards around Rock Hill sit on heavy clay, which can be hard, slow to drain and short on organic matter. Laying sod straight on top of that is the fastest way to get a lawn that looks great for a month and then struggles.

Start with a soil test

Clemson Extension recommends testing the soil 2 to 3 months before planting, so there is time to add what the test calls for (Clemson HGIC, Lawn Establishment). In South Carolina, homeowners can send samples to the Clemson Agricultural Service Laboratory. Clemson has a simple guide on how to take a sample (Clemson HGIC, How to Take a Soil Sample).

Loosen and amend

  • Work any lime and fertilizer the test recommends into the top 4 to 6 inches of soil.
  • Clemson suggests tilling in about an inch of organic matter, and warns against tilling sand into clay (Clemson HGIC, Lawn Establishment).

Fix the grade

Water should run away from the house, not toward it. Fill low spots, smooth high ones, and keep the finished soil about an inch below sidewalks and driveways so the sod sits flush (Clemson HGIC, Lawn Establishment).

Firm it up and dampen it

Rake out rocks and roots, firm the soil, and dampen it right before the sod goes down so the roots are not laid onto hot, dry ground.

What we do on every install

We cut out the old lawn, fix the grade, bring in soil where it is needed, lay the sod tight and water it in. Soil prep is part of every install, not an add on.
