St. Augustine vs. Zoysia: Choosing the Right Grass for Your South Florida Yard

If you're putting in a new lawn or replacing a struggling one, the single most important decision you'll make is which grass to use. In South Florida, the two most common choices are St. Augustine and Zoysia — and they're very different animals. Here's what you need to know before you commit.
St. Augustine: The South Florida Standard
St. Augustine is the most widely used turfgrass in South Florida, and for good reason. It establishes quickly, handles the heat and humidity well, and produces a thick, lush carpet that looks great year-round. It tolerates partial shade better than most warm-season grasses — a real advantage in yards with large trees or structures casting shadows. The tradeoff: it needs consistent irrigation, is susceptible to chinch bugs (a major pest in South Florida), and doesn't handle heavy foot traffic as well as some alternatives.
Zoysia: Tougher, But Slower
Zoysia has been gaining popularity in South Florida over the past decade. It's denser and more wear-resistant than St. Augustine, making it a better choice for yards with kids, pets, or frequent outdoor entertaining. It also uses less water once established and has better natural resistance to pests. The downside is that Zoysia establishes slowly — it can take a full season to fill in — and it goes dormant and turns brown during cold snaps, which do occasionally hit South Florida in January and February.
What About Bahia and Bermuda?
You'll also see Bahia grass in South Florida, mostly on larger properties and along roadsides. It's extremely drought-tolerant and low-maintenance, but it has a coarser texture and doesn't give you the manicured look most homeowners want. Bermuda grass is another option — it's tough and recovers quickly from damage — but it requires full sun and frequent mowing to stay looking sharp. For most residential properties, St. Augustine or Zoysia will serve you better.
The South Florida Mowing Rules Are Different
Regardless of which grass you choose, mowing height matters more here than in most of the country. St. Augustine should be kept at 3.5 to 4 inches — cutting it shorter stresses the grass and opens the door to weeds and pests. Zoysia can be mowed slightly shorter, around 2 to 2.5 inches. Never remove more than one-third of the blade in a single mow. And keep your blades sharp — a dull blade tears the grass rather than cutting it cleanly, which invites disease.
Fertilizing in South Florida: Timing Is Everything
South Florida's growing season is essentially year-round, but fertilizing rules are strict. Miami-Dade, Broward, and Palm Beach counties all have fertilizer blackout periods during the rainy season (typically June through September) to protect waterways. Outside those windows, a slow-release nitrogen fertilizer applied three to four times a year keeps most lawns healthy. Always follow local ordinances — fines for off-season fertilizing are real.
Our Recommendation
For most South Florida homeowners, St. Augustine is still the go-to — it's proven, widely available as sod, and performs well across a range of conditions. If you have a high-traffic yard, want lower water use long-term, or are willing to wait for establishment, Zoysia is worth the investment. When in doubt, call us — we can walk your property and give you a straight answer based on your specific soil, sun exposure, and how you use your yard.
Choosing the right grass is the foundation of a healthy South Florida lawn. Get it right from the start and everything else — watering, fertilizing, pest control — becomes easier. If you'd like a professional assessment of your property, Schoen Property Specialist is here to help.
