How to Install New Sod the Right Way

April 18, 2026 Under Sod Editorial Team 5 min readUpdated

Under Sod 4-2-5 is blended into the top 4 to 6 inches of soil before the sod goes down. The label method is incorporation. If you cannot mix it in, use the quarter-rate topical application.

The rate is one 25-pound bag per pallet of sod (500 square feet), which is 50 pounds per 1,000 square feet, blended into the top 4 to 6 inches of soil.

Sod fails or thrives in the first 48 hours. Here's how to get it right.

Installing sod isn't complicated, but the details matter. Skip a step and you'll see it weeks later in thin, slow-rooting turf.

The Installation Process

  1. Prep the soil — clear debris, loosen the top 4 inches of prepared topsoil, up to 6 where the topsoil lift is deeper, and rake to a smooth final grade.
  2. Feed underneath — spread your under-sod fertilizer and blend it into the top 4 to 6 inches of soil where the new roots will land.
  3. Lay the sod — stagger the seams like brickwork, butt the edges tight, and avoid stretching the rolls.
  4. Roll it — use a lawn roller to press the sod into firm soil-to-soil contact and remove air pockets.
  5. Water deeply — apply about an inch the first day, then keep consistently moist for 2–3 weeks.

Get these five steps right and the rest takes care of itself.

Don't skip the underneath

What you put under the sod in step 2 determines how fast and deep it roots.

Step two

Day 30: OVER SOD™ 8-0-6 is step two, a phosphorus-free surface feed with mostly slow-release nitrogen, at one 25-pound bag per four pallets of sod (2,000 square feet), which is 12.5 pounds per 1,000 square feet: about 1 pound of nitrogen, 0.75 pound of potash, and no phosphate. Water it in. If day 30 falls inside your state's fertilizer blackout, wait for the first allowed date. OVER SOD™ ships spring 2027. About Over Sod 8-0-6
