Why St. Augustine gets its own calculator
St. Augustine isn't your average turf, and estimating it as if it were can throw your order off. It's a warm-season grass with broad, coarse blades that thrives in the heat and humidity of southern lawns, and it's almost always sold as thick slabs stacked on pallets rather than the thin rolls you'd see with cool-season grasses. That changes the coverage math, which is why the calculator above starts from slab-and-pallet assumptions you can fine-tune to your supplier.
Planning a St. Augustine lawn
- Buy fresh and lay fast. Its dense slabs hold a lot of moisture and shouldn't sit stacked for long.
- Time it for warmth. Late spring into summer is the sweet spot; it won't establish in cold soil.
- Prep the soil. Set a topsoil depth above to get the cubic yards you'll need underneath.
- Mind the coverage. Slab and pallet sizes vary by grower — enter the real numbers from your quote.
Cost and timing
St. Augustine tends to price at the higher end of warm-season sod. Get a full estimate — grass, delivery, labor — with the sod cost calculator, and nail the timing with our guide to the best time to lay sod by climate zone.
Handling a grass that comes in big, tender slabs
St. Augustine is almost always sold as thick slabs rather than thin rolls, because its coarse, spongy runners don't roll up tightly the way fine-bladed cool-season grasses do. That shapes how you plan an order. Slabs cover more per piece — often around a couple of square feet each — so your piece count comes out lower than it would for a rolled grass covering the same lawn; set the coverage box to your supplier's slab size for an accurate number.
The slabs are also heavier and more fragile at the edges, which crumble easily during handling. Order a little extra with the waste slider to cover the inevitable broken corners and the offcuts around curves, and plan to lay the slabs the day they arrive rather than letting them sit and dry out.
Getting a warm-season lawn to root
St. Augustine thrives in warm, humid climates and establishes best when the soil itself is warm — generally late spring through summer — rather than in cool weather, when its roots barely move. Lay the slabs tight with staggered seams, like brickwork, press them into firm contact with moist, raked soil, and keep the new lawn consistently wet for the first couple of weeks while the roots knit in.
It's a dense, shade-tolerant grass that crowds out many weeds once established, though it doesn't handle heavy foot traffic as well as some warm-season alternatives. Measure your yard, add a waste allowance, and use the cost calculator to fold in delivery and installation labor so the estimate reflects the whole job, not just the turf.
Cost, coverage and waste for slabs
Because St. Augustine comes in larger slabs, both your piece count and your pricing behave a little differently from rolled grass. Suppliers may quote by the slab, by the pallet or by the square foot, so translate everything back to your measured area to compare offers fairly. Set the coverage box to the real slab size before reading the count, and lean toward the higher end of the waste slider — the tender edges crumble and curved borders eat more turf than straight ones.
For the full picture, run your square footage through the cost calculator to layer in delivery and installation labor on top of the material. If only part of the lawn needs work, measuring just those zones — rather than the whole yard — keeps the order and the cost tight to what you'll actually lay.
Frequently asked questions
How much does a pallet of St. Augustine sod cover?
A pallet of St. Augustine sod commonly covers around 400 to 500 square feet depending on the farm and how the slabs are cut. Because it's a warm-season grass usually sold as slabs rather than thin rolls, confirm the pallet's stated coverage and enter it above for an exact pallet count.
When should I lay St. Augustine sod?
St. Augustine is a warm-season grass, so it establishes best in late spring through summer when soil is warm and there's no frost risk. Laying it in the active growing season gives the roots time to knit before cooler weather. See our best-time-to-lay-sod guide for climate-zone specifics.
Is St. Augustine sod more expensive?
St. Augustine often sits at the higher end for warm-season sod because of its dense, wide-bladed growth and popularity in hot, humid regions. Prices vary by area and cultivar, so enter your local price per pallet or square foot above for a personalized estimate.
