How to Lay Sod

Updated September 2026 · Home Project Resources

Sod is a perishable product. It is harvested as living grass with about half an inch of soil attached, and it starts dying the moment it is stacked on a pallet. In warm weather you have roughly 24 hours from harvest to get it down and watered, sometimes less above 85 degrees. That single fact drives the entire project.

Which means the ground must be completely prepared before the truck arrives, not after. Kill the old grass, grade, till, amend, level, and lightly firm the soil first. Then order the sod, take delivery, and lay it the same day. People who do it in the other order end up with yellow strips on a pallet and a lawn that never fully recovers.

Ordering the right amount? Our sod calculator turns your yard dimensions into square feet, pallets, and rolls, with a waste allowance for cuts.

A note on numbers. This page gives quantities, depths, schedules, and the specifications that belong on a sod order or an installation quote, not dollar figures. Sod is a farm product sold delivered, and the price moves with grass type, region, season, and how far the truck drives.

How to lay sod, in order

1. Kill or strip the existing grass and weeds, 2 to 3 weeks ahead if using herbicide.
2. Remove the debris and any old thatch layer.
3. Check and correct the grade, sloping away from the house.
4. Till 4 to 6 inches deep and break up compaction.
5. Amend with compost and whatever a soil test tells you to add.
6. Rake to final level, about 1 inch below walks and driveways.
7. Roll lightly and water the bare soil the day before delivery.
8. Take delivery and lay immediately, starting on the longest straight edge.
9. Stagger the seams like brickwork, butting pieces tight without stretching.
10. Roll the finished lawn to press roots into soil.
11. Water deeply within 30 minutes of laying each section.
12. Follow the watering schedule for the first 3 to 4 weeks.

A 2,000 square foot yard is a full day for two people, plus a day or two of prep work beforehand. The prep is the longer half of the project and it is the half that decides the result.

Prepare the ground before the sod arrives

Kill the existing lawn. A non selective glyphosate based herbicide applied to actively growing grass takes 7 to 14 days to work, and you want to wait the full label interval before tilling. Read and follow the label, which is the legal instruction, and keep kids and pets off until it dries. If you would rather not use herbicide, a rented sod cutter strips the old lawn mechanically and gives you a result the same afternoon. It is the priciest of the rentals on this project and the only one that removes two weeks from the schedule.

Either way, get the dead material off the site. Tilling dead grass and thatch into the top few inches leaves a spongy layer that decomposes, settles, and gives you dips a year later.

Fix the grade now. Ground next to the house should fall away at roughly 6 inches over the first 10 feet. This is the moment to correct a negative slope, because you cannot fix it once the lawn is down. Look for low spots that puddle, and fill them with soil rather than with extra sod thickness.

Till 4 to 6 inches deep. A rear tine tiller is a one-day rental and the single most useful machine on the job. The goal is to break compaction so roots can actually go somewhere. Sod laid on compacted clay roots into the top half inch and then stops, and that lawn browns out in the first dry spell of its second summer.

Amend based on evidence, not habit. A basic soil test from your county extension office is the cheapest item in this whole project and it tells you pH and nutrient levels. Most turf grasses want pH between 6.0 and 7.0. Lime raises pH, elemental sulfur lowers it, and both take months to act, which is exactly why you do it before the sod goes down and not after.

Work in 1 to 2 inches of compost across the area regardless. On a 2,000 square foot yard, 1 inch of compost is about 6.2 cubic yards.

Apply a starter fertilizer. Something high in phosphorus, a 10-20-10 or similar, raked into the top inch. Some states restrict phosphorus on lawns, so check local rules first.

Rake to final level, then firm it. Break up clods, pull out rocks bigger than an egg, and rake until the surface is smooth. Then roll it with a lawn roller about a third full of water, or walk it in overlapping passes. You want soil firm enough that your footprints are barely visible, not fluffy. Fluffy soil settles unevenly under sod and gives you a lumpy lawn.

Water the bare soil lightly the day before delivery. Damp soil, not muddy. Sod laid on hot dry dirt loses moisture out the bottom immediately.

Grade for the inch that sod occupies

Here is the detail almost everyone misses. Sod is about 1 inch thick, soil and grass together, sometimes a bit more for thick cut varieties.

So your finished soil grade has to sit about 1 inch below every hard edge: sidewalks, driveways, patios, garage aprons, and the top of any edging. If you rake the soil flush with the sidewalk and then lay sod on it, the lawn stands an inch proud of the concrete. That edge scalps every time you mow, it dries out first, and it looks wrong forever.

At the house foundation, keep the finished grass surface at least 6 inches below the siding or any wood, and slope away.

Check it with a straightedge laid from the walk out across the prepared soil. A 6 foot level or a straight 2x4 works. If you are working out square footage on an irregular yard, our square footage calculator breaks odd shapes into rectangles and triangles for you.

Laying the sod

Start on the longest straight edge. A driveway, a walk, a fence line, or a chalked string line if you have no straight edge. That first row sets the alignment for everything after it.

Butt the pieces tight, end to end and side to side. Snug, no gaps. A gap of even half an inch dries out from both sides and turns into a brown seam that weeds find within a month.

Never stretch a piece to close a gap. This is the single most common mistake. Sod stretches easily when it is wet and heavy, and it feels like it is working. Then it shrinks back as it dries and you get a gap wider than the one you were closing. Cut a filler piece instead.

Stagger the seams like brickwork. Start every other row with a half piece so end joints do not line up across rows. Continuous seams running across the lawn become channels for water, and they show as visible lines for the first season. Staggered joints knit together far faster.

Do not overlap and do not leave sod riding up. Where two pieces meet, the surfaces should be level with each other. If one is high, pull a little soil from under it.

Work on plywood, not on fresh sod. Lay a sheet of plywood or two on the finished area to distribute your weight while you work forward. Kneeling directly on new sod presses divots into the soft prepared soil.

Cut with a sharp knife against a straightedge. A serrated bread knife, a sod knife, or an old machete all work. Cut from the grass side with the piece flat on the ground and run the blade along a board or a spade edge. For circles around trees and sprinkler heads, cut a bit small and butt the pieces rather than cutting a perfect circle.

On slopes, run the rows across the slope, not up and down. Perpendicular to the fall line. On anything steeper than about 3:1, pin the pieces with biodegradable sod staples, roughly 2 to 4 per piece, or the first heavy watering slides your lawn downhill.

Lay it the day it arrives. If you truly cannot finish, unstack the remaining pallets into a single layer in the shade and water them. Sod left stacked in summer heats up in the middle of the pallet and cooks. Stacked sod at 90 degrees can be dead in 36 hours.

Roll it, because contact is everything

Once the last piece is down, roll the whole lawn with a water fillable lawn roller about one third full. It is the cheapest rental on the list and the one people skip.

Rolling is not cosmetic. New sod roots by pushing new growth out of the bottom of the sod mat into the soil below. It cannot do that across an air gap. Rolling presses the mat into intimate contact with the prepared soil and collapses the voids that always exist under freshly laid strips.

Roll in two directions, perpendicular passes, and do it before the sod has been heavily watered so you are not compacting mud. Do not fill the roller completely. You are seating the sod, not compacting the seedbed you just spent a day loosening.

Then water. The first watering is the big one, covered next.

The watering schedule, which is where new sod actually dies

More new sod is lost to a bad watering schedule than to every other cause combined. Too little and the mat dries and shrinks. Too much and the roots stay in the saturated top half inch and never go down.

The first watering. Within 30 minutes of laying a section, water it until the soil beneath the sod is wet, not just the grass. That usually means about 1 inch of water, which is more than people expect. Test it by lifting a corner piece and pushing a finger into the soil below. It should be wet to a depth of 3 to 4 inches. On a hot day, water each section as you finish it rather than waiting for the whole lawn.

Week by week:

Adjust for weather without apology. In 95 degree heat with wind you may need three light waterings a day in week one. In cool damp fall weather you may need half of what the table says. The rule underneath the table is simple: the sod mat and the top 2 inches of soil below it should never dry out during the first two weeks, and should never be soupy either.

Water early. Between 5 and 9 in the morning is best. Evening watering leaves the blades wet overnight, which invites fungal disease in warm weather.

How to measure an inch of water. Set a few empty tuna cans or straight sided containers on the lawn while the sprinkler runs. When they have half an inch in them, you have applied half an inch. Time it once and you will know your sprinkler's rate forever.

Stay off it. Minimal foot traffic for the first two weeks, and keep pets off entirely. Footprints in saturated new sod become permanent dips.

The tug test tells you when it has rooted

Around day 10 to 14, grab a corner of a piece and pull gently upward.

• It lifts easily and you can see the bare soil. Not rooted yet. Keep the daily watering going.
• It resists, and the mat tears rather than lifting. Roots have knitted into the soil. You can start stretching the interval between waterings.

Check in three or four different spots, including the shadiest and the sunniest, because they root at different rates. Full rooting to the point where the lawn behaves like an established lawn takes about 4 to 6 weeks in the growing season, longer in cool weather.

If a piece still lifts freely at day 21, look for a cause: an air gap under it, a dry spot the sprinkler misses, or soil that was never loosened underneath.

First mow, and the one third rule

Wait until the sod is rooted enough to resist the tug test, usually 2 to 3 weeks. Mowing before that pulls pieces loose under the mower wheels and tears new roots.

Let it dry out slightly before the first mow. Skip a watering the day before so the ground is firm enough for the mower without rutting.

Mow high on the first cut. Set the deck at the tall end of the range for your grass: 3 to 4 inches for tall fescue and Kentucky bluegrass, 1 to 2 inches for bermuda, 2 to 3 for zoysia and St. Augustine.

Follow the one third rule from the first mow onward. Never remove more than one third of the blade height in a single cut. If your target height is 3 inches, mow when it hits 4.5 inches. Cutting more than a third at once shocks the plant, forces it to spend stored energy regrowing leaves, and slows root development at the exact moment roots matter most.

Sharp blade only. A dull blade tears the grass instead of cutting it, and torn tips brown out. Sharpen at the start of the season and once mid season.

Leave the clippings unless they clump. They return nitrogen and they do not cause thatch.

Do not fertilize again until about 4 to 6 weeks after installation, then a balanced turf fertilizer at label rate.

Worked example: the quantity takeoff for a 2,000 square foot yard

Say the front and side yard together measure 2,000 square feet after subtracting the driveway and beds.

Quantity. Sod is sold by the square foot, by the roll, and by the pallet. A standard pallet covers 400 to 500 square feet depending on the farm, so 2,000 square feet is 4 to 5 pallets. Order 5 to 10 percent extra for cuts and waste, so call it 2,150 square feet, which is 5 pallets at 450 square feet each.

Individual pieces vary by region: small slabs at 16x24 inches, or big rolls at 2x5 feet or wider. Confirm the piece size with your supplier so you know what you are lifting. A standard slab weighs 30 to 40 pounds wet.

The full shopping and rental list, with the quantity you need for this yard:

How the compost number came out. 2,000 square feet at 1 inch deep. One inch is 1/12 of a foot, so 2,000 x 0.0833 = 166.7 cubic feet. Divide by 27 cubic feet per cubic yard = 6.17 cubic yards. Our cubic yard calculator runs this for any depth, and the square footage calculator handles the yard measurement if the shape is irregular.

Getting a real number for your yard. Sod is one of the easier trades to price honestly, because the product is sold by the square foot and the square footage is something you can measure yourself. Call two local sod farms with your square footage, your grass type, and your delivery address, and ask each one for the delivered price per square foot, the pallet coverage, the delivery charge, and the harvest day. Then ask one landscaper for an installed price on the same square footage with prep included. Three numbers built on one measurement is all the comparison you need, and it beats any national average, including anything you read online.

Ask the farm one more question: what day is it cut? Sod cut the morning it is delivered is a different product from sod cut two days earlier and held on a pallet.

Sod versus seed, honestly

Sod wins when you need the lawn usable soon, when you are fighting erosion on a slope, when you are outside the seeding window for your region, or when you want to avoid a season of weed battles.

Seed wins on cost by a factor of ten, and it lets you pick exactly the cultivar blend you want. It also roots deeper from the start, since the plant grows in place rather than transplanting.

Timing. Cool season grasses, fescue, bluegrass, and rye, prefer early fall or spring for both sod and seed. Warm season grasses, bermuda, zoysia, and St. Augustine, prefer late spring into early summer. Sod is more forgiving of off season installation than seed is, but avoid laying sod in peak summer heat if you can, because that is when the 24 hour clock is shortest and the water demand is highest.

If your project involves reshaping the yard first, our how to build a deck and how to install a fence guides cover the work that should happen before sod goes down, since heavy equipment and post digging will wreck a new lawn.

Frequently asked questions

How long can sod sit on the pallet before it dies?

About 24 hours in warm weather, and as little as 12 to 18 hours above 85 degrees. Stacked sod generates heat in the middle of the pallet, which is why the center pieces are usually the first to fail. In cool weather, 48 to 72 hours is survivable. If you cannot lay it right away, unstack the pallets into a single layer in the shade and keep them watered.

Do I need to till before laying sod?

Yes in almost every case. Tilling 4 to 6 inches deep breaks up compaction so the new roots have somewhere to go. Sod laid on hard compacted soil roots only into the top half inch and then stalls, which shows up as a lawn that browns fast in the first dry spell. The only exception is soil that is already loose and well structured, which is rare in a yard that has had construction traffic on it.

How soon can I walk on new sod?

Keep off it for the first two weeks except for essential checks, and use a sheet of plywood to spread your weight if you must cross it. The soil beneath is saturated and freshly loosened, so footprints turn into permanent dips. Normal foot traffic is fine at about 3 to 4 weeks, once the tug test shows real resistance.

How much should I water new sod?

Water to about 1 inch immediately after laying, so the soil beneath the mat is wet 3 to 4 inches down. Then water once or twice daily for the first two weeks at 1/4 to 1/2 inch each time, keeping the mat and the soil under it from ever drying out. From week three, taper toward deep and infrequent, ending at 1 to 1.5 inches per week total.

Why is my new sod turning yellow or brown?

Usually water, in one direction or the other. Dry brown edges and shrinking seams mean not enough. Yellow, soft, slightly sour smelling sod means too much, and the roots are drowning in saturated soil. Lift a corner and check the soil beneath, which tells you which problem you have within seconds.

When can I mow new sod?

Once it passes the tug test, typically 2 to 3 weeks after laying. Skip a watering the day before so the ground is firm, mow high on the first pass, and use a sharp blade. Never remove more than one third of the blade height in one cut, which is the rule that matters most in the first month.

Can I lay sod over existing grass?

Do not. The old grass decomposes into a spongy layer that stops the new roots from reaching real soil, and the whole lawn settles unevenly as it breaks down. It also leaves the old lawn's weeds and diseases sitting right underneath. Kill or strip the existing turf first, every time.

How do I get an accurate price to sod a yard?

Measure the area first, then call two local sod farms and one landscaper with the same square footage. From the farms, ask for the delivered price per square foot, the pallet coverage, the delivery charge, and the harvest date. From the landscaper, ask for an installed price that names the prep: herbicide or strip, till depth, compost depth, grade correction, and whether the first watering is included. Sod itself is the largest single line on a DIY job, and the prep materials and rentals together come to a meaningful fraction of it again. Professional installation costs several times the material alone, because prep is the long half of the work.

The short version

Sod is alive and on a clock, so all the preparation happens before the truck arrives. Kill the old grass, grade away from the house, till 4 to 6 inches, amend with compost, rake to about an inch below every hard edge, and firm it lightly.

Lay the same day it is delivered. Start on a straight edge, butt every seam tight, stagger the joints like brickwork, cut fillers rather than stretching pieces, and roll the whole thing so the mat sits against the soil.

Then water like the lawn depends on it, because it does. Deep and daily for two weeks, then taper to deep and infrequent. Tug test around day 10 to 14, first mow at week two or three, and never take more than a third of the blade.

Our sod calculator will convert your yard into pallets and rolls with a waste allowance, and the square footage calculator handles the measuring if the shape is anything but a rectangle.
