Where Can I Buy St. Augustine Grass Seed?
If you’re wondering where to buy St. Augustine grass seed, here’s the short and honest answer: true St. Augustine grass seed is rarely sold commercially. St. Augustine (Stenotaphrum secundatum) is most commonly propagated vegetatively — as sod, plugs, or sprigs — because viable, commercially available seed for this turf species is generally not produced. That said, there are many practical places and alternatives to get the lawn you want. I’ll walk you through why seed is uncommon, where to buy the grass in other forms, how to choose a supplier, and my personal tips for a successful installation.
Why you rarely find St. Augustine grass seed
St. Augustine spreads by stolons (above-ground runners) and is a warm-season grass that performs best in the southern U.S. It doesn’t produce abundant, uniform seed that seed companies can harvest and sell, and many cultivars are sterile or don’t come true from seed. For that reason, sod farms and nurseries sell it as sod, plugs, or sprigs — the vegetative material that ensures the turf maintains the cultivar characteristics you want.
Where to buy St. Augustine if you can’t get seed
Think of shopping for St. Augustine more like buying a shrub or a tree: you’ll look for a nursery or turf farm that sells the living plant in a usable form.
- Local garden centers and independent nurseries — Many stock St. Augustine plugs or potted turf squares in the spring and early summer months.
- Big-box stores — Home Depot and Lowe’s often carry St. Augustine sod or plugs regionally. Availability depends on season and your USDA hardiness zone.
- Local sod farms and turf producers — These are usually the best source for freshly harvested St. Augustine sod and sprigs. Search for “sod farm” or “turf farm” plus your city or county.
- Landscape contractors and lawn services — They often sell or install St. Augustine and can source quality sod or plugs at scale.
- Online turf suppliers — Some companies ship plugs or small rolls of sod regionally. If you search for “St. Augustine sod” or “St. Augustine plugs” you’ll find turf-specific retailers who can deliver within certain distances.
- Community marketplaces — Facebook Marketplace, Craigslist, or local gardening groups can be a source of leftover sod or plugs sold by homeowners or contractors.
How to choose the right place to buy
When buying vegetative material instead of seed, quality and timing matter more than price.
- Buy locally when possible — Freshly harvested sod or plugs from a nearby supplier will establish faster and ship with less stress.
- Ask for the cultivar — Common varieties include ‘Floratam’, ‘Palmetto’, ‘Seville’, and ‘Captiva’. Each has different shade tolerance, cold tolerance, and pest resistance.
- Request a sample or photos — For sod, check color, density, and that the sod pieces hold together without excessive soil loss.
- Check delivery and installation options — Sod is heavy and perishable; many turf farms offer delivery and installation services, which I recommend if you’re redoing a large area.
- Seasonality — Planting is best in late spring through early summer when the grass is actively growing. Avoid trying to install in cool, dormant seasons.
Estimated costs and ordering tips
Prices vary a lot by region, but expect these ballpark numbers:
- Sod: typically ranges from about $0.50 to $1.50 per square foot, depending on the supplier and region.
- Plugs: usually sold in trays or packs; cost per plug can be lower but you need many to cover a lawn (spacing depends on how quickly you want it to fill in).
- Delivery and installation: additional costs that can exceed the price of the material for large jobs.
Measure your lawn carefully before ordering. Turf farms usually sell by the square foot or pallet; for plugs, ask how many plugs per tray and the recommended spacing for quickest fill-in.
Where I personally buy and why
“For most of my lawn projects I go directly to a local turf farm or a reputable nursery. The material is fresher, and they give honest advice about the best cultivar for my shady backyard.” — a gardener’s view
My go-to strategy is simple: find a local turf farm and visit if I can. I once replaced a struggling Bermuda lawn with ‘Palmetto’ St. Augustine by buying plugs from a nearby farm. The plugs were healthy, planted in May, and within one season the lawn filled in beautifully. Buying locally saved on delivery and meant I could check cultivar authenticity and freshness in person.
If you find “St. Augustine seed” online
Be cautious. Some online sellers list “St. Augustine seed” but what they’re often selling is either a mislabeled product, a seed mix intended for other grasses, or home-saved seed that won’t reliably produce the cultivar you expect. Before buying seed online, confirm with the seller what species and cultivar you’re actually getting, and read reviews from other buyers.
Installation and care tips after purchase
Whether you choose sod or plugs, these basics help establishment:
- Prepare the soil: remove weeds, loosen compacted soil, and work in compost or starter fertilizer as recommended.
- Install in warm weather: St. Augustine roots best when soil temperatures are warm and the grass is actively growing.
- Water correctly: sod needs daily watering for the first two weeks, then gradually reduce; plugs require regular moisture until stolons spread.
- Mow at the right height: St. Augustine prefers 2.5–4 inches depending on the cultivar.
Final thoughts
So, where can you buy St. Augustine grass seed? In most places, you can’t — or at least not reliably. The practical route is to buy St. Augustine as sod, plugs, or sprigs from local nurseries, turf farms, big-box stores with garden centers, or trusted landscapers. Do your homework on cultivar, timing, and supplier reliability, and you’ll end up with a thick, lush St. Augustine lawn that seed alone wouldn’t have given you.
If you want, tell me your location and lawn size and I can suggest likely local sources and estimate how much material you’ll need — I love helping people get the right grass for their yard.
