Before the truck comes
Everything that goes wrong with a do-it-yourself sod job goes wrong before the sod arrives. Strip the old lawn, grade, spread topsoil, rake it smooth, and run every sprinkler zone. The prep guide covers each step. Water the bed lightly the day before so the sod lands on moist soil.
Line up the tools: a sharp utility knife or sod knife with spare blades, a wheelbarrow, a landscape rake, gloves, a few sheets of plywood to kneel on, flags for the sprinkler heads, and a lawn roller if you can borrow one. Then line up a second person. One pallet covers 450 square feet and takes two people about two hours. Doing it alone takes most of a day, and the sod does not wait.
Delivery day
The truck sets the pallet on your driveway or at the curb. Nobody has to be home, but somebody has to start laying that day. A stacked pallet heats from the inside, and in summer the sod in the middle yellows within a day. Move the pallet into shade if you can, keep it out of standing water, and do not soak the stack. Work straight from the pallet to the ground.
If you ordered more than one pallet, have them set where they are closest to the ground they cover. Wheelbarrowing sod across a yard is the slowest part of the job.
The first row
Start along the longest straight edge you have, usually the driveway or the front walk, and lay the first row end to end with the pieces butted tight. That row sets every row after it, so take your time and keep it straight. Kneel on the sod you have already laid, or on plywood, and stay off the raked soil. Footprints in the bed become dips in the lawn.
Lay each piece flat and slide it into the one before it. Do not stretch it to close a gap. Stretched sod shrinks back as it dries and leaves a seam that browns.
Stagger the seams like brickwork
Start the second row with a half piece so its seams land in the middle of the first row’s pieces. Keep that offset on every row. Seams that line up leave a long straight gap that dries out first, sinks first, and shows for a season. Staggered joints disappear in a few weeks because each piece is held on three sides by its neighbors.
On a slope, run the rows across the hill rather than up and down it, so water cannot channel down a seam. Keep the seams tight, edge to edge, never overlapping. Overlaps dry out and die.
Curves and sprinkler heads
Lay full pieces over the curve, then cut the excess with the knife from the soil side, following the bed edge. Use small trimmings in the middle of the lawn, never at the edges, because small pieces at an edge dry out and lift. Cut around each flagged sprinkler head with the head sitting just below the top of the sod, and leave the flag until the first mow.
Fill any gap wider than a finger with a scrap of sod, not with soil. Soil-filled gaps grow weeds.
Press it and water it
Once the last piece is down, roll the whole lawn with a half-filled roller, or walk it down under plywood, so the roots are pressed against the soil with no air pockets. Then water within 30 minutes. Soak until water runs through the sod and the soil under it is wet, and lift a corner to check. From there follow the day-by-day schedule in how to water new sod: daily for ten days, twice a day in July and August, then taper. Keep people and dogs off it for two weeks, and hold the first mow until the sod resists a gentle tug.
Mistakes we see
- Waiting a day. Sod on a summer pallet does not survive an overnight. Lay it the day it lands.
- Laying on dry, dusty soil. Moist soil grabs roots. Dust pulls water out of them.
- Stretching pieces to close gaps. They shrink back. Cut a filler piece instead.
- Seams that line up. Offset every row by half a piece.
- Small pieces at the edges. They dry out and lift. Put trimmings in the middle.
- No plan for the seams. Seams dry first. Hand-water them for the first few days on top of the sprinkler run.
Three pallets or fewer on flat ground is a good weekend job. Past that, or on a slope, or on a yard with a drainage problem, the install is worth paying for. Delivery vs. installation vs. DIY lays out the trade, and the services page has the whole job priced.
Questions people ask
How long can sod sit on the pallet?
In summer heat, it needs to go down the day it arrives. The inside of a stacked pallet heats up fast and the sod yellows within a day. In cool weather you have a little more room, but never plan on more than 24 hours.
Why do you stagger sod seams?
The same reason bricks are staggered. Seams that line up leave a long straight gap that dries out, sinks, and shows for a season. Offset every row by half a piece and the lawn knits together as one sheet.
Do I need a lawn roller?
It helps. A light roller, or walking the sod down with plywood, presses the roots against the soil so they can take water. Skip the heavy roller on wet clay, which just compacts it.
