How to Prepare Soil for Sod in Central Florida
New sod is only as good as what it's laid on. Here's how we build the soil first — including COMAND compost underlayment — so a new lawn roots fast and stays thick on Florida sand.

How do you prepare soil for sod in Central Florida?
Remove the old grass and roots, grade the area so water drains away and the new sod meets the existing lawn level, then amend the sandy soil with compost — we use COMAND, spread ¼ to ¾ inch deep. Firm and moisten the surface, lay fresh sod within 24 hours of harvest, and water it in the same day.
Why New Sod Struggles on Florida Sand
Most Central Florida yards sit on sand that holds very little water or nutrients.
What we see: new sod that looks great for two weeks, then thins, yellows and needs water every day — especially in full sun and along driveways where the soil is poorest.
The root cause: sandy soil is low in organic matter. Water and fertilizer run straight through it, so young roots have nothing to hold onto. UF/IFAS notes that adding compost to sandy Florida soils improves their ability to hold water and nutrients and supports healthy soil life (UF/IFAS Extension).
The fix: build the soil before the sod goes down. That's the difference between a lawn that survives and one that thrives.
Our 6-Step Soil Preparation for Sod
This is exactly how we prepare every sod install across Winter Park, Oviedo and Winter Springs.
Remove the old grass and roots Included
We cut out the existing turf, weeds and root mat so the new sod contacts soil — never laid over old grass.
Grade for drainage and a level tie-in Included
Standard grading so water moves away from the house and the new sod sits level with the lawn you're keeping — no uneven seams. Heavier regrading is quoted after an on-site look.
Amend with COMAND compost Recommended option
We spread COMAND compost ¼", ½" or ¾" deep across the prepared area to add organic matter where Florida sand has almost none.
Firm and moisten the surface
A smooth, lightly firmed, damp surface gives new roots full contact from day one.
Lay fresh sod within 24 hours of harvest
ProVista, CitraBlue or Floratam St. Augustine, or CitraZoy, Empire or Zeon Zoysia — tight, staggered seams, installed by our own crew.
Water it in the same day

What Is COMAND Compost?
A Florida-made compost we use as a sod underlayment and in our topdressing blend.
COMAND is a stabilized compost produced in Florida through controlled, high-temperature (thermophilic) composting, a process that eliminates weed seeds and pathogens (Council-Oxford). Its maker describes it as a natural source of organic matter and beneficial microbes that helps soil hold water and nutrients, and states it holds up to six times its weight in water (COMAND).
For a new lawn, that means the top inches of soil stay moist longer between waterings and roots have organic matter to grow into — exactly what Florida sand is missing.
Roots With Somewhere to Go
Organic matter gives new roots structure and moisture to grow into instead of loose, dry sand.
Holds Water in Sand
Compost helps sandy soil hold water longer, so new sod is less likely to dry out between cycles.
Feeds Soil Life
Beneficial microbes help cycle nutrients so the lawn relies less on quick-release fertilizer.
A Smoother, Denser Lawn
An even, amended bed means fewer low spots and a tighter, more uniform turf canopy.
How Much Compost Goes Under Sod?
We offer three COMAND underlayment depths. Volumes below are per 1,000 sq ft of lawn.
| Depth | COMAND per 1,000 sq ft | Installed price per 1,000 sq ft | Best for |
|---|---|---|---|
| ¼ inch | about 0.8 cubic yards | about $240 | Decent native soil that needs an organic boost |
| ½ inch | about 1.5 cubic yards | about $450 | Typical Central Florida sand — our most common choice |
| ¾ inch | about 2.3 cubic yards | about $690 | Very poor, bright-white sand, full sun, or estate lawns where we want the best possible start |
COMAND underlayment is an optional upgrade at $300 per cubic yard installed; your exact yardage is measured at the free estimate. Sod itself is $2.00 per sq ft installed for St. Augustine and $2.15 for Zoysia, with old-grass removal and standard grading included.

Already Have a Lawn? COMAND Topdressing
You don't need new sod to fix thin turf on sand. We topdress existing St. Augustine and Zoysia lawns with a 70/30 sand-and-COMAND compost blend, spread in thin layers that work down into the canopy — adding organic matter and smoothing low spots at the same time.
Topdressing with our sand-and-compost blend starts at $300 per cubic yard. See our lawn topdressing and leveling service.

"Healthy lawns and landscapes do not exist without healthy living soil."
We've installed sod across Central Florida since 2005, owner-operated with UGA turfgrass training. Every install starts below the grass: removal, grading, and the organic matter Florida sand is missing. It's why our lawns root fast and stay dense.

Soil Prep for Sod: Questions We Hear
How do you prepare soil for sod in Florida?
Remove the old grass and roots, grade so water drains away and the new sod meets the existing lawn level, amend the sandy soil with compost such as COMAND spread ¼ to ¾ inch deep, firm and moisten the surface, lay fresh sod within 24 hours of harvest, and water it in the same day.
Do I need topsoil or compost under new sod in Florida?
Sod will grow on bare sand, but it struggles: sand holds little water or nutrients. A layer of compost under the sod adds the organic matter sandy Florida soil lacks, helping roots establish and holding moisture longer between waterings. We recommend it for most Central Florida installs.
How much compost should go under sod?
We offer ¼, ½ and ¾ inch COMAND underlayment — about 0.8, 1.5 and 2.3 cubic yards per 1,000 square feet, or roughly $240, $450 and $690 installed at $300 per cubic yard. Half an inch suits most Central Florida sand; ¾ inch is for very poor white sand, full sun or estate lawns.
What is COMAND compost?
COMAND is a Florida-made compost produced by controlled high-temperature composting, which eliminates weed seeds and pathogens. Its maker describes it as a source of organic matter and beneficial microbes that helps soil hold water and nutrients. We use it under new sod and in our 70/30 sand-and-compost topdressing blend.
Is soil preparation included in your sod price?
Yes — removing the old grass and standard grading so the new sod sits level with your existing lawn are included in $2.00 per square foot for St. Augustine and $2.15 for Zoysia. COMAND underlayment is an optional upgrade at $300 per cubic yard installed, and heavier regrading is quoted on site.
Can you lay new sod over existing grass?
No. Sod laid over old grass sits on a dying root mat instead of soil, so it roots poorly and often fails. We always remove the existing turf, weeds and roots before grading and laying new sod.
