St. Augustine grass seed is harder to find than other lawn grass types because it rarely produces viable seed
St. Augustine grass spreads through stolons — above-ground runners that root into soil — not through seed. Most St. Augustine varieties sold commercially do not produce seed at all, or produce seed so rarely that seed companies do not stock it. If you search for "St. Augustine grass seed," you will find very little, and what you do find is often mislabeled or from unreliable sellers.
The practical alternative is sod or plugs. Sod is mature grass laid in rolls; plugs are small rooted sections you plant in rows. Both are available from local sod farms, landscape supply yards, and online retailers that ship to your region. If you are set on seed, a few specialty growers sell it, but you should understand what you are buying and whether it will actually grow in your yard.
Key Takeaways
- Most St. Augustine grass does not produce seed, so sod and plugs are the standard way to establish a lawn.
- Local sod farms and landscape supply yards are your fastest and most reliable source, and they can advise you on which variety suits your climate zone.
- Online sod retailers like Sodco and Lowe's ship rolls or plugs to many regions, though shipping costs are high and delivery windows are narrow.
- If you find St. Augustine seed for sale, verify the variety name and seller reputation, because mislabeled seed is common.
- Plugs cost less upfront than sod but take longer to fill in — usually 6 to 12 weeks for a dense lawn.
Local sod farms and landscape supply yards
Your county extension office or local landscape contractor can direct you to sod farms within 50 miles of your home. These farms grow St. Augustine sod year-round in warm climates and can tell you which varieties thrive in your specific zone. They also know the soil and sun conditions in your area and can recommend the right type — some St. Augustine varieties tolerate shade better than others, and some handle salt spray if you live near the coast.
Buying from a local farm means you can pick up sod the same day or next day, which keeps the grass fresher. Sod dries out quickly once it is cut, so a short transport time matters. Farms typically sell by the pallet (400 to 500 square feet) and charge $0.50 to $1.50 per square foot, depending on the variety and your region. Plugs from the same farms usually cost $0.10 to $0.25 per plug.
Landscape supply yards — the kind that sell mulch, stone, and soil — often stock sod and plugs from regional farms. They may have smaller order minimums than farms do and can deliver to your home for a fee. Call ahead to confirm they have St. Augustine in stock and ask what varieties they carry.
Online sod retailers and home improvement stores
Lowe's, Home Depot, and specialty retailers like Sodco and The Sod Store ship sod and plugs to many parts of the country. Enter your zip code on their website to see what is available in your area. Shipping costs are steep — often $100 to $300 depending on order size and distance — and delivery windows are narrow (usually a single day). Sod arrives in a truck and must be laid within 24 hours or it will dry out and die.
Online ordering works best if you live in a region with high sod demand (Florida, Texas, California, the Southeast) where retailers have local warehouses. If you live in a colder climate or far from a warehouse, shipping may be unavailable or prohibitively expensive. Check the retailer's coverage map before you add items to your cart.
Home Depot and Lowe's also sell small quantities of plugs in trays, usually 18 to 50 plugs per tray. These are cheaper to ship than full pallets of sod and are a good option if you are filling in bare spots or starting a small lawn. Plugs take longer to establish than sod — expect 6 to 12 weeks for a thick, mowed lawn — but the cost per square foot is lower.
Specialty seed companies and mail-order nurseries
A handful of seed companies sell St. Augustine seed, usually under the variety name "Floratam" or "Raleigh." Seed Warehouse, Burpee, and some regional nurseries carry it. Before you order, confirm the seller's location and reputation. St. Augustine seed has a short shelf life and low germination rates even when fresh, so buying from a company that stores it properly matters. Read customer reviews and look for sellers that may provide germination or offer refunds.
Seed is much cheaper than sod or plugs — typically $20 to $50 per pound — but germination is unpredictable. St. Augustine seed needs soil temperatures above 70°F, consistent moisture, and 14 to 21 days to sprout. Even under ideal conditions, germination rates are often below 50 percent. If you use seed, plan to overseed or fill gaps with plugs later.
What to check before you buy
Confirm the variety name. Common St. Augustine types include Floratam, Raleigh, Bitter Blue, and Palmetto. Each has different shade tolerance, salt tolerance, and cold hardiness. Floratam is the most common and handles heat well but struggles in shade. Raleigh is more cold-hardy and shade-tolerant. Ask the seller which variety they stock and whether it is suited to your climate zone and sun exposure.
If you are buying sod, ask the farm or retailer when it was cut. Fresh sod (cut within 24 hours) is greener and establishes faster. Sod that has been stacked for more than a few days may have yellowed or started to dry out. Plugs are less time-sensitive but should still be planted within a few days of arrival.
Check the seller's shipping policy. Some retailers will not ship to certain states or regions due to agricultural regulations. A few states restrict sod imports to prevent the spread of pests or diseases. Confirm your address is in a delivery zone before you order.
Timing and seasonal availability
St. Augustine sod and plugs are available year-round in warm climates, but spring and early fall are the best times to plant. Sod laid in late spring (April to May) or early fall (August to September) establishes quickly because temperatures are warm but not extreme. Summer planting is possible but requires more frequent watering. Winter planting in cold climates is risky because the grass will not root in before frost.
If you are ordering online, place your order at least one week in advance. Retailers need time to cut sod or prepare plugs, and delivery trucks run on set schedules. During peak season (April to June and August to September), some retailers may have longer wait times or limited availability.
Cost comparison: sod vs. plugs vs. seed
| Option | Cost per square foot | Time to full lawn | Best for |
|---|---|---|---|
| Sod | $0.50–$1.50 | 2–4 weeks | Fast results, large areas |
| Plugs | $0.10–$0.25 | 6–12 weeks | Budget-conscious, small areas |
| Seed | $0.05–$0.15 | 8–16 weeks | Very small areas, experimental |
Sod is the most expensive option upfront but gives you a finished lawn in weeks. Plugs cost less but require patience and consistent watering. Seed is the cheapest but has the lowest success rate with St. Augustine and is not recommended for most home lawns.
Frequently Asked Questions
Can I grow St. Augustine from seed I collect myself?
Most St. Augustine varieties do not produce seed, so there is nothing to collect. Even the few varieties that do produce seed have very low germination rates. Collecting and planting your own seed is not a practical way to establish a lawn.
What if my local sod farm does not have St. Augustine in stock?
Ask when they expect their next shipment, or ask them to recommend a nearby farm that carries it. If no local source has it, check online retailers that ship to your zip code. You can also ask your county extension office for a list of sod suppliers in your region.
Is it cheaper to buy plugs online or from a local nursery?
Local nurseries are usually cheaper because they do not charge shipping. Compare the per-plug price at a local supplier with the online price plus shipping before you order. For large orders, online retailers may have better bulk discounts, but shipping often erases the savings.
How long does sod last before I have to lay it?
Sod should be laid within 24 hours of delivery. If it sits longer, the grass will yellow and the roots will dry out. If you cannot lay it the day it arrives, ask the retailer if they can delay delivery or if you can pick it up yourself.
Do I need to water plugs more often than sod?
Yes. Plugs have smaller root systems and dry out faster than sod. Water plugs daily for the first two weeks, then gradually reduce frequency as they establish. Sod needs daily watering for the first week, then can be watered less often as the roots grow into the soil.
