The mistakes that kill new sod are almost all in one of three places: the pallet sat too long, the soil underneath was never prepared, or the watering was wrong. Everything else on this list is a variation on those three.
Sod is a living thing with its roots cut off, and it has roughly a two-week window to reattach itself to the ground. Most of what follows is about not wasting that window.
1. Letting the pallet sit
The most expensive mistake and the most common one.
Sod is harvested with about an inch of soil, rolled or stacked warm and damp, and put on a pallet. Inside that stack the material starts to heat and compost itself. In summer, sod can be dead in 24 to 36 hours — and the top layer will still look green, which is how people install dead grass without knowing it.
The fix: schedule delivery for the morning you are installing, not the day before. If sod arrives and cannot go down immediately, break the pallet apart, spread the pieces in a single layer in shade, and keep them damp. That buys you hours, not days.
If your delivery slips to Friday and you are laying on Sunday, do not lay it. Reschedule the delivery.
2. Skipping soil preparation
You cannot fix bad ground with good grass. Sod laid on compacted, unprepared soil roots two inches deep and then quits.
What has to happen first: kill and remove the old lawn, fix the grade so water runs away from the house — at least six inches of fall within ten feet of the foundation — loosen the top four to six inches, work in compost on clay or builder fill, and set the final surface an inch below every hard edge so the lawn sits flush.
Our preparation guide covers the full sequence. It is roughly 70 percent of whether the lawn takes, and it is the first thing cut when a quote comes in high.
3. Laying sod over living grass
It does not root into grass. It roots into soil.
Sod laid over an existing lawn sits on a layer of dying vegetation that then decomposes, leaving a spongy, uneven surface. Meanwhile every weed and every Bermuda rhizome underneath is working its way up through the seams. Within a season you have a lumpy lawn with the old lawn's weed problem.
4. Aligning the seams
Sod pieces go down like brickwork — staggered, so the end joints of one row land in the middle of the pieces in the next.
Aligned seams create continuous straight channels that water runs along instead of soaking into, and the whole lawn is visibly gridded for its first year. It is a two-second decision per piece that shows for months.
Two more seam rules: butt the pieces tight against each other without overlapping, and on any slope, run the rows across the slope rather than up and down it, then pin them with sod staples.
5. Not rolling it
After the last piece is down, roll it with a water-filled roller about a third full.
The purpose is contact. Sod laid on even a well-raked surface bridges over small hollows, and air pockets under sod are where the brown patches come from. Rolling presses everything into contact so roots can find soil.
Do not fill the roller. A heavy roller compacts the soil you just paid to loosen, which is the opposite of the goal.
6. Watering wrong, in both directions
Not enough, or not deep enough. The first watering after installation needs to soak three to four inches into the soil beneath the sod, not just wet the blades. Then two to three light waterings a day for the first two weeks in hot weather.
Too much, later. After the first two or three weeks, constant saturation starves roots of oxygen and, worse, gives them no reason to grow downward. That produces a lawn with a two-inch root system that collapses the first hot week you go away.
The screwdriver test settles both. A long screwdriver should slide easily through the sod and four inches into the soil. If it stops short, you need more water. If the ground squelches and smells sour, you need less. Our watering schedule has the full taper.
7. Ignoring coverage gaps
The most common "my sod died" call turns out to be one strip that never got water — usually along a driveway or a south-facing wall, where radiant heat off the concrete dries the soil hours faster than the rest of the yard.
Test the irrigation before installation. Put a few tuna cans out, run each zone fifteen minutes, and see whether they fill evenly. Fix the blocked heads and the sunk heads then, while you can still reach them.
8. Mowing too soon, or too short
Wait for the tug test. Grab a corner and pull — if it lifts like a rug, it is not rooted, usually around day 10 to 14.
First mow: highest setting, sharp blade, and skip watering that morning so the mower does not rut soft ground. Never take more than a third of the leaf blade at once. Scalping a lawn that is still establishing sets it back weeks.
9. Fertilizing like it is an established lawn
New sod wants a starter fertilizer with phosphorus, which drives root development, worked into the soil before the sod goes down.
A high-nitrogen lawn fertilizer at install pushes leaf growth the roots cannot support, and on some products can burn turf that is already stressed. Save the regular feeding program for six weeks out.
10. Walking on it
Two weeks. No kids, no dogs, no wheelbarrow shortcuts across the corner. Foot traffic on unrooted sod slides it out of contact and creates exactly the air pockets rolling was meant to eliminate.
This is the rule everybody breaks, because on day two it looks like a finished lawn. It is a green rug that has not yet decided to stay.
When you should install it yourself
We install sod, and we will still say this plainly.
A flat yard under about 2,000 square feet, on a mild day, with prep already done, is a genuine DIY job. Two people, a wheelbarrow, a sharp knife, and a rented roller. The work is simple. It is just heavy — a pallet weighs 2,000 to 3,000 pounds and covers roughly 450 to 500 square feet, so know how many pallets you are moving by hand before you commit your weekend.
Hire it out when there is grading or drainage work, when the yard is big enough that installation would span two days (it must not), when access is bad, or when the delivery timing cannot be controlled. The single strongest argument for a crew is that they lay a whole pallet the day it arrives, which is the mistake at the top of this list.

- Bermuda Sod →
Bermuda sod is the right answer for most Laredo yards, and it is not close: hybrid Bermuda takes full sun and sustained triple-digit heat better than anything else that still looks like a lawn, uses noticeably less water than St. Augustine once established, and repairs its own wear as it spreads.
- Caliche Excavation & Land Grading →
Land grading in Laredo is really two jobs: setting the fall so water leaves the house, and finding out what the caliche is doing before you build a lawn on top of it. We laser-grade to roughly a quarter inch of fall per foot away from the slab, and we probe the profile first, because a cemented hardpan shelf a few inches down changes every decision that follows.
- Topsoil & Soil Amendment →
Topsoil and soil amendment is what you are really buying when you buy a lawn, because the four inches under the grass decide almost everything that happens afterwards. Laredo soil tests come back alkaline and high in free calcium carbonate, which is exactly why brand-new St.
- St. Augustine Sod →
St. Augustine sod is the grass to plant where a Laredo yard has real shade — under a mesquite, an anacua or a huisache, or on the north side of a two-story house where Bermuda thins out and quits by the second summer.
- Zoysia Sod →
Zoysia sod is what Laredo homeowners buy once they have owned a St. Augustine lawn and grown tired of feeding it — it grows slowly, so you mow less, and it grows densely, so it crowds out most weeds without a chemical program propping it up.
Frequently asked questions
Why is my new sod dying?
Nine times out of ten it is water — either not enough, or not reaching the soil beneath the sod. Push a screwdriver through the turf into the ground. If it stops at an inch, the roots are sitting on dry soil no matter how wet the blades look.
How long can sod sit on the pallet?
Install it the same day it arrives. Sod is harvested with about an inch of soil and stacked warm and damp, and the middle of a pallet begins composting itself. In summer heat, grass can be dead in 24 to 36 hours. This is the most expensive mistake on the list and the easiest to avoid.
Why are there gaps between my sod pieces?
Either the pieces were butted loosely at install, or the sod dried out and shrank before it rooted. Fill narrow gaps with a sand and topsoil mix and keep them damp. Gaps left open dry the exposed edges out and become permanent brown seams.
Do you have to roll new sod?
Yes, lightly. Rolling presses the sod into the soil so the roots make contact instead of bridging over air pockets. Use a water-filled roller about a third full — heavy rolling compacts the soil you just spent money loosening.
When can you walk on new sod?
About two weeks, or whenever it passes the tug test. Walking on unrooted sod slides it out of contact with the soil and creates air pockets, and those become the brown patches that show up a month later.
Can you lay sod over an existing lawn?
No. It will not root into living grass. The old turf dies underneath and rots into a spongy layer, the grade goes uneven, and every weed that was there comes back through the seams within a season.
