Why St. Augustine Grass is Perfect for Florida
Listen, when it comes to creating that picture-perfect Florida lawn you’ve been dreaming about, St. Augustine grass (Stenotaphrum secundatum) is your best friend. This isn’t just any ordinary grass – it’s the superstar of warm-season turfgrasses that thrives in Florida’s unique climate like it was born for the job (which, honestly, it kind of was).
Picture this: a lush, thick carpet of green that can handle Florida’s blazing sun, afternoon thunderstorms, and even those pesky shady spots under your favorite palm tree. That’s St. Augustine grass for you! It’s the most popular choice among Florida homeowners, and for good reason – this grass means business when it comes to creating curb appeal.
What Makes St. Augustine Grass Special?
St. Augustine grass is like that reliable friend who’s always got your back. This warm-season powerhouse originally hails from the coastal areas around the Gulf of Mexico and Mediterranean, so it already knows how to handle waterfront living. What makes it special? Let me break it down for you:
Key Characteristics That’ll Make You Fall in Love
- Growth Pattern: This grass spreads through stolons (think of them as above-ground runners), creating that dense, weed-choking coverage you want
- Texture: Those beautiful medium to coarse blades sport a gorgeous blue-green color that screams “Florida paradise”
- Soil Flexibility: It’s not picky! St. Augustine grass adapts to well-drained soils with a pH range of 5.0–7.5
- Climate Range: Thrives in USDA Zones 7–12, making it perfect for Florida’s varied regions
The Good, The Great, and The Reality Check
Why You’ll Love St. Augustine Grass
- Thick Coverage That Means Business: This grass creates such dense turf that weeds don’t stand a chance. It’s like having a natural bouncer for your lawn!
- Shade Champion: Unlike many warm-season grasses, St. Augustine actually performs well in partially shaded areas. Got trees? No problem!
- Salt-Tolerant Superstar: Living near the coast? St. Augustine grass laughs in the face of salty conditions that would make other grasses cry.
- Quick Results: When you install it via sod, plugs, or sprigs, you’ll see results faster than you can say “Florida lawn goals.”
The Reality Check (Every Grass Has Its Quirks)
- High-Maintenance Relationship: This grass loves attention. We’re talking frequent mowing, regular fertilization, and staying on top of pest control.
- Not Built for Heavy Traffic: If you’re planning to host the neighborhood football games, St. Augustine might not be your MVP. It’s more of a “look but don’t stomp” kind of grass.
- Thatch Issues: Give it too much love (over-watering and over-fertilizing), and you’ll end up with thatch buildup that nobody wants to deal with.
- Pest Magnet: Unfortunately, chinch bugs and diseases like gray leaf spot think St. Augustine grass is as delicious as you think it’s beautiful.

Meet the St. Augustine Grass Family
Choosing the right variety is like picking the perfect pet – you want one that fits your lifestyle and environment. Here’s your lineup of St. Augustine all-stars:
Floratam: The Crowd Favorite
Floratam is the most popular St. Augustine grass in Florida, and there’s a good reason it’s been the go-to choice since 1973. This variety was literally designed by the University of Florida and Texas A&M University to handle Florida conditions.
What Makes Floratam Special:
- Fast Spreader: Creates dense coverage that makes weeds pack their bags
- Sun Worshipper: Needs at least 6 hours of direct sunlight to be its best self
- Originally Bug-Resistant: While it was bred to resist chinch bugs, these little troublemakers have gotten craftier over time
The Fine Print:
- Mowing Height: Keep it at 3.5–4 inches
- Best For: Sunny residential or commercial lawns where you need quick establishment
- Heads Up: Struggles in shade and can be sensitive to certain herbicides, especially when temps hit above 85°F (and yes, this applies even to herbicides rated for St. Augustine grass)
BitterBlue: The Classic Choice
BitterBlue is like that vintage car that never goes out of style. Selected way back in the 1930s, this variety has proven its worth with a gorgeous dark blue-green color and finer texture that homeowners love.
BitterBlue’s Best Features:
- Shade Friendly: Handles partial shade better than many varieties (though not as well as the newer kids on the block)
- Cold Hardy: Perfect for northern Florida where temperatures can get a bit nippy
- Beautiful Texture: Creates that premium, lush lawn look
The Details:
- Mowing Height: 3.5–4 inches
- Perfect For: Homeowners wanting a classic, attractive lawn with moderate sun/shade mix
- Watch Out For: Moderately susceptible to pest infestations and diseases like gray leaf spot
Raleigh: The Cold Weather Warrior
Raleigh is your go-to choice if you’re dealing with cooler Florida winters. Developed by North Carolina State University in 1980, this variety was built to handle temperature drops that would make other St. Augustine grasses shiver.
Raleigh’s Superpowers:

Seville: The Ornamental Beauty
Seville is the refined, elegant cousin of the St. Augustine family. This dwarf variety brings fine texture and a lower growth habit that’s perfect for those “magazine-worthy” landscapes.
Why Seville Stands Out:
- Versatile Performer: Handles both full sun and moderate shade beautifully
- Fine Texture: Creates that manicured, upscale look
- Low Profile: Grows shorter than standard varieties
Seville Specifics:
- Mowing Height: 2–2.5 inches (shorter than most varieties)
- Perfect For: Ornamental areas and smaller landscapes where aesthetics matter most
- Consider This: Less cold-tolerant and prone to thatch buildup and pest issues
Palmetto: The Versatile Superstar
Palmetto St. Augustine is like the Swiss Army knife of grass varieties. With over two billion square feet sold worldwide, this variety has proven it can handle whatever you throw at it.
Palmetto’s Greatest Hits:
- Climate Chameleon: Thrives everywhere from humid coastal areas to inland regions

CitraBlue’s Modern Advantages:
- Disease Resistant: Superior resistance to gray leaf spot, large patch, and take-all root rot
- Eco-Friendly: Requires less nitrogen fertilizer (your wallet and the environment will thank you)
- Low Maintenance: Lateral growth pattern means less frequent mowing
CitraBlue Details:

Getting Your St. Augustine Grass Started
Since St. Augustine grass doesn’t produce viable seeds (it’s too cool for that), you’ll need to plant it using sod, sprigs, or plugs. Think of it as adopting rather than growing from scratch – and honestly, that’s better because you get instant gratification!
Before you get started, proper site preparation is absolutely crucial. This means soil testing, proper grading, and removing any existing vegetation that might compete with your new grass baby. For the complete playbook, check out UF/IFAS’s Preparing to Plant a Florida Lawn.
Sodding: The Express Lane to Lawn Paradise
Sod installation is like getting the deluxe package – it’s the fastest, most effective way to get your St. Augustine grass established. Yes, it costs more upfront, but you get immediate coverage, instant erosion control, and weed suppression from day one.
Your Sod Installation Game Plan:
- Prep Your Canvas
- Remove all existing grass and weeds (trust us, this step matters)
- Grade the soil for proper drainage
- Test soil pH (aim for 5.0–7.5) and amend if needed
- Lay It Right
- Install sod pieces in a staggered brick pattern to prevent gaps
- Press edges tightly together – gaps are weed highways
- Roll It Out
- Use a lawn roller to ensure perfect soil contact
- Water Like You Mean It
- Immediately water deeply to moisten soil 6–8 inches down
New Sod Watering Schedule:
- First 7–10 days: Water multiple times daily to keep topsoil moist
- Gradually reduce frequency over the following weeks

Sprigging and Plugging: The Budget-Friendly Route
If you’re working with a tighter budget and don’t mind waiting for results, sprigging and plugging are cost-effective alternatives. Just remember – patience is key with these methods.
Sprigging Method:
- Spread sprigs end-to-end in furrows 6–12 inches apart
- Lightly cover with soil, keeping leaf blades exposed
- Keep soil consistently moist until roots establish and stolons spread
Plugging Method:
- Plant plugs (small sod sections) at 6–24 inch intervals
- Closer spacing = faster coverage (but more initial work)
- Follow similar watering schedule as sodding

Keeping Your St. Augustine Grass Happy and Healthy
The secret to a gorgeous St. Augustine lawn isn’t just planting it and hoping for the best – it’s about consistent, smart maintenance. Think of it as a long-term relationship where a little attention goes a long way.

- Footprints remain visible after walking on the lawn
Smart Watering Strategy:
- Apply ½–¾ inch of water per session
- Water deeply but infrequently to encourage deep root growth
- Adjust frequency based on season and rainfall
Pro Timing Tips:
- Water more frequently during peak heat
- Reduce watering in cooler months
- Always follow local water restrictions

Fertilizing: Feeding Your Grass Right
Proper fertilization is like providing balanced nutrition – your St. Augustine grass needs the right nutrients at the right time to thrive. But remember, more isn’t always better!
Smart Fertilization Strategy:
Application Schedule:
- Apply nitrogen-rich fertilizer 2–6 times annually based on your region
- Fertilize during active growing seasons (spring through early fall)
Before You Feed:
- Always test soil pH and nutrient levels first
- Use slow-release nitrogen products to prevent nutrient runoff
Regional Guidelines:
- Northern Florida: 2–4 pounds nitrogen per 1,000 sq ft annually
- Central Florida: 3–5 pounds nitrogen per 1,000 sq ft annually
- Southern Florida: 4–6 pounds nitrogen per 1,000 sq ft annually
