St. Augustine seed is harder to find than other grass types because it rarely produces viable seed
St. Augustine grass does not produce usable seed in most of the United States. The variety grown in lawns is sterile or produces seed so unreliably that commercial seed packets are almost never sold. If you see "St. Augustine seed" for sale online or in a store, it is either mislabeled or will not germinate.
What you can actually purchase is St. Augustine sod — rolls of established grass with soil attached — or plugs, which are small rooted sections you plant individually. Both are living plants, not seeds. If a seller claims to have St. Augustine seed in stock, contact them directly to ask what they are actually selling, because the product name often misleads buyers.
The reason matters: St. Augustine spreads by stolons (above-ground runners), not seed. Sod and plugs use this natural growth method. Seed does not work for this grass, so you will waste money ordering it.
Key Takeaways
- St. Augustine grass does not produce viable seed, so you cannot buy seeds — you buy sod or plugs instead.
- Sod arrives in rolls ready to lay down and costs more upfront but establishes faster than plugs.
- Plugs are individual rooted plants that cost less but take longer to fill in a lawn and require more maintenance during establishment.
- Local sod farms, landscape supply companies, and some garden centers stock St. Augustine sod and plugs; online retailers ship sod but charge high freight costs.
- Sod and plugs are perishable and must be installed within one to three days of delivery, so plan your planting before you order.
Local sod farms are the cheapest and fastest option
A sod farm within 50 miles of your home is your best source. Search online for "[your city] sod farm" or "[your county] sod supplier." Call and ask if they grow St. Augustine and what their current price is per roll or pallet. Most farms sell directly to homeowners and charge $0.30 to $0.60 per square foot for sod, depending on your region and the time of year.
Farms deliver same-day or next-day because sod dies quickly once cut. You install it when ready after delivery. This speed and low cost make local farms the standard choice for large areas. If you need only a small patch, some farms have a minimum order (often one pallet, which covers 450 square feet), so ask before you commit.
To find farms, also check with your county extension office or local landscape contractors — they know which farms are active and can recommend one that matches your timeline and budget.
Garden centers and landscape supply stores stock sod and plugs year-round
Most garden centers in St. Augustine grass regions carry sod rolls and plugs during the growing season (spring and early summer in the South). Call ahead to confirm they have St. Augustine in stock, because availability changes. Prices at garden centers run higher than farms — typically $0.50 to $0.80 per square foot for sod — but you can see the product before buying and take it home the same day.
Plugs are more common at garden centers than at farms. A single plug costs $1 to $3 and covers about 1 square foot when it fills in. You buy them by the flat (usually 18 to 50 plugs per flat) and plant them 12 inches apart. Plugs are less perishable than sod, so you have a few days to plant them after purchase.
Landscape supply companies (the wholesale-style stores that serve contractors) also stock both sod and plugs. Some allow homeowner purchases; others require a contractor license. Call to ask their policy before visiting.
Online retailers ship sod but freight costs are steep
Retailers like Lowe's, Home Depot, and specialty sod companies ship St. Augustine sod nationwide, but shipping costs $200 to $600 depending on the order size and your distance from the warehouse. The sod itself may cost $150 to $300, so freight often doubles your total bill. Sod also arrives in a compressed state and must be unrolled and watered within 24 hours or it dies.
Online ordering makes sense only if you live far from a local sod farm and need a small area (under 500 square feet). For larger lawns, the freight cost makes it cheaper to hire a local contractor who buys from a farm and installs it, even though you pay labor.
Plugs ship better than sod because they are smaller and lighter. Online plug orders from retailers like Etsy sellers or specialty nurseries run $30 to $80 per flat plus shipping. Delivery takes 5 to 10 days, and plugs arrive dry but alive. Water them when ready upon arrival.
Timing your purchase: sod season and availability
St. Augustine sod is cut and sold year-round in warm climates, but spring (March to May) and early fall (August to September) are peak seasons when farms have the most stock and prices are lowest. Summer heat stresses newly laid sod, so many homeowners avoid June and July. Winter is possible but slower — sod grows slowly in cold, so establishment takes longer.
Plugs are available spring through early fall. Planting plugs in winter is possible but not recommended because they establish slowly in cold soil and may not survive if frost heaves them out of the ground.
Order sod or plugs at least one week in advance so the farm can schedule cutting and delivery. If you need sod urgently, call farms directly — some keep cut sod in coolers for same-day pickup or next-day delivery, but availability is not may provide.
What to check before you buy
Ask the seller whether the sod is certified weed-free. Sod can carry seeds of crabgrass, nutsedge, and other weeds. Certified sod has been inspected and treated to reduce weed risk. It costs slightly more but saves you months of weeding.
Request the age of the sod. Sod cut within the last 24 hours is ideal. Sod older than 3 days has a much lower survival rate. Farms will tell you the cut date if you ask.
Confirm the thickness of the soil layer. Sod should have 1 to 1.5 inches of soil attached. Thinner sod dries out faster and is harder to establish. Thicker sod is heavier to handle but more forgiving.
For plugs, check that they are actively growing — the roots should be white and visible at the bottom of the container, and the leaves should be green and firm. Plugs that are brown, wilted, or rootbound will struggle after planting.
Comparing sod versus plugs for your situation
| Factor | Sod | Plugs |
|---|---|---|
| Cost per square foot | $0.30–$0.80 | $1–$3 per plug (covers 1 sq ft when mature) |
| Time to full coverage | when ready (visible lawn in 2–3 weeks) | 3–6 months (slower fill-in) |
| Installation labor | High (heavy, requires equipment for large areas) | Low (hand-plant, lighter work) |
| Perishability | Must install within 24 hours | Can wait 3–5 days after delivery |
| Weed pressure during establishment | Low (sod covers bare soil when ready) | High (bare soil between plugs invites weeds) |
| Best for | Large areas, fast results, low maintenance during establishment | Small patches, tight budgets, flexible timeline |
Frequently Asked Questions
Can I grow St. Augustine from seed if I order online?
No. St. Augustine does not produce viable seed in the United States. Any product labeled "St. Augustine seed" will not germinate. If you order it, contact the seller for a refund and ask what they actually have in stock — they may have mislabeled plugs or sod.
How much sod do I need for my lawn?
Measure your lawn in square feet (length × width). One pallet of sod covers 450 square feet. Most farms sell by the pallet, though some sell individual rolls (usually 10 square feet per roll). Order 5 to 10 percent extra to account for cuts and waste.
What is the difference between sod and plugs?
Sod is a large mat of established grass with soil attached, laid down in rolls. Plugs are small rooted plants (usually 2 to 4 inches wide) planted individually. Sod covers your lawn when ready; plugs take months to fill in but cost less and are easier to transport.
Do I need to water sod or plugs right after planting?
Yes. Water sod deeply within two hours of installation and keep the soil moist (not soggy) for the first two weeks. Water plugs when ready after planting and maintain consistent moisture for the first month. Both need frequent watering during establishment because the roots are shallow.
Can I install sod myself or should I hire someone?
You can install sod yourself if the area is small (under 500 square feet) and you have help. Sod is heavy and awkward to handle. For larger lawns, hiring a contractor is faster and often cheaper than renting equipment and spending a full day on the work. Plugs are easier to install yourself.
