Strengths

• Full-sun performer: thrives in South Florida heat and humidity with strong direct light.
• Fast establishment: vigorous stolons cover ground quickly and close post-install seams faster than finer cultivars.
• Coastal capable: good salt tolerance for typical beachside and coastal sites with proper irrigation.
• Proven track record: decades of Florida installation data—behavior, pest response, and care requirements are well understood.

Considerations

• Shade: low tolerance. Needs 6–8+ hours of direct sun; thins quickly in shade versus Palmetto or CitraBlue.
• SCMV/LVN susceptible: not suitable for SCMV-affected sites — see notice above.
• Chinch bugs: monitor hot, sunny edges and along concrete regularly; Floratam’s sun preference overlaps exactly with chinch bug habitat.
• Mow height: looks best at 3.5–4.5″; scalps noticeably if cut too low — not a fit for anyone wanting a low-cut lawn.

Choose Floratam if you want…

• A full-sun yard with the most vigorous, fastest-spreading St. Augustine available—Floratam covers ground faster than any other cultivar we install.
• The classic, bold South Florida look—coarse blades and deep green color that reads as lush and established from the street.
• A proven performer in coastal conditions with good salt tolerance and heat resilience in Palm Beach County’s climate.
• Fast repair from damage, pet wear, or construction—Floratam’s vigorous stolons fill bare spots quickly.
• A grass type with decades of Florida-specific data on care, pests, and behavior—nothing surprises you.

Pick a different option if…

• Your lawn was diagnosed with or is suspected to have SCMV/LVN—Floratam is susceptible and re-sodding with it on an affected site carries real reinfection risk. See the SCMV-resistant replacement guide.
• You have significant shade—even 3–4 hours of shade per day will produce visible thinning over time. Palmetto or CitraBlue are better fits.
• You want a finer, more refined surface—Floratam’s coarse texture is a feature to some and a drawback to others. CitraBlue and Palmetto both offer a noticeably softer, tighter look.
• You want to mow lower—Floratam at anything below 3.5″ looks scalped and stressed. If you want a lower-cut lawn, Zoysia or CitraBlue are better fits.
• You’re in a yard with mixed light and mature trees—Floratam will thin in those zones regardless of irrigation or care.

Nothing covers ground faster

Floratam’s vigorous stolon spread is the most practically useful thing about it.

In large open yards, post-renovation repairs, or any situation where you want visible coverage quickly, Floratam’s aggressive lateral spread outpaces every other St. Augustine cultivar we install. Seams close faster, bare spots fill sooner, and the lawn looks established earlier than Palmetto or CitraBlue in equivalent conditions. For homeowners on HOA timelines who need visible progress fast—and whose yards qualify for Floratam—this matters. See our HOA re-sod guide for timing guidance.

The definitive full-sun St. Augustine

Optimized for the exact conditions most South Florida front yards provide.

South Florida has no shortage of wide-open, full-sun residential yards—no canopy, reflective driveways and pool decks amplifying heat, and six or more hours of direct sun daily. That’s exactly the environment Floratam was developed for. Where Palmetto‘s shade tolerance is a feature that goes unused in these sites, Floratam channels all of its breeding toward maximum vigor and heat performance in exactly those conditions. The result in a qualifying yard is a lawn that looks and performs the way the category promises.

The classic South Florida look—intentionally coarse

For homeowners who want the bold look, not a finer alternative to it.

Floratam’s coarse texture isn’t a limitation—it’s the cultivar’s visual identity. The wide blades, deep green color, and bold surface feel like traditional South Florida turf in the way that finer cultivars don’t. Some homeowners specifically choose Floratam because the CitraBlue or Zoysia aesthetic is too refined for what they want. If your frame of reference is the thick, classic grass that’s been in Florida yards for decades, Floratam is the reference cultivar—not a compromise version of a finer grass.

Days 0–7: Knit + hydration

• Goal: keep sod consistently moist—not soggy, not drying at edges or seams.
• Floratam’s coarse blades and vigorous stolons begin anchoring within a few days in warm weather.
• Driveways, concrete edges, and south-facing exposures dry fastest—check these zones daily and hand-water if needed.
• No foot traffic until rooting is underway; seams are easy to shift before anchor.

Days 8–14: Rooting + first mow

• Goal: begin tapering irrigation frequency as roots anchor into the soil profile.
• First mow typically arrives at 10–14 days; confirm rooting with a gentle tug before mowing.
• Set the rotary at 3.5–4″ for the first cut—never below this, never remove more than ⅓ of blade in one pass.
• Begin reducing irrigation run times; light but frequent watering after rooting builds shallow roots.

Weeks 3–4: Transition to established care

• Goal: deep, infrequent irrigation—approximately 1″ per week including rainfall.
• Floratam’s vigorous stolons are actively closing seams at this point; visible progress should be clear by week 3.
• Establish your edging routine now—Floratam reaches bed lines faster than finer cultivars.
• A light starter fertility application to support continued rooting and color development.

Weeks 5–8: Full coverage + color

• Goal: consistent mowing at 3.5–4.5″ to build the thick canopy Floratam is known for.
• Floratam’s bold texture and deep green color are fully expressed by week 6–8 in summer conditions.
• Thin spots at this stage almost always trace to irrigation coverage gaps, shade, or mowing mistakes.
• Most Floratam lawns are fully settled by week 6 in South Florida’s growing conditions—faster than Zoysia, comparable to Palmetto.

Chinch bugs (scattered yellowing near hot edges)

The most common Floratam pest in South Florida—and the most important to catch early.

• Chinch bugs feed on Floratam in the hottest, sunniest zones first—driveways, sidewalk edges, south-facing fence lines, and around pool equipment.
• Early sign: scattered yellow patches expanding from those edges during hot, dry conditions.
• Fix: confirm identity before treating (see our chinch bug guide); apply a labeled insecticide and water it in. Treat early—established chinch bug populations damage turf faster than almost any other lawn pest in South Florida.
• Prevention: keep the lawn well-watered in hot dry spells; drought-stressed Floratam is significantly more vulnerable.

Gray leaf spot (irregular tan lesions with purple border)

Develops in hot, wet summer conditions—particularly after heavy nitrogen applications.

• Most common July–September; look for tan lesions with a purple or brown halo on individual blades. Severe outbreaks turn turf gray and matted.
• Fix: reduce nitrogen immediately; switch to morning-only irrigation; apply a labeled fungicide if spreading actively. See our fungus ID guide to confirm before treating.
• Prevention: avoid summer nitrogen applications during wet periods; avoid evening or overnight irrigation.

Large patch (circular straw-colored rings)

A cool/wet season disease that develops when turf stays moist in fall through early spring.

• Expanding circular rings with a yellow or straw-colored outer ring are the diagnostic sign. Most visible October–April.
• Fix: switch to morning-only irrigation immediately; reduce irrigation frequency; apply a labeled fungicide if rings are actively expanding. See our large patch guide for full treatment steps.
• Prevention: don’t apply nitrogen in late fall or winter; avoid overwatering as temperatures drop.

Scalping (brown, stubble appearance after mowing)

Floratam at a low cut height looks significantly worse than it does at the correct height—the recovery is real but slow.

• Cutting below 3″ removes the growing points and leaf mass Floratam needs to sustain density; the result is a brown, patchy surface that takes weeks to recover.
• Fix: raise the mowing height immediately and do not cut again until recovery is visible. Light irrigation and time; avoid fertilizing during active recovery.
• Prevention: set your mower deck at 3.5″ minimum and confirm the blade is sharp. Floratam’s coarse blades magnify the visual impact of a bad cut more than finer-bladed cultivars.

Spring (green-up → active growth)

• Resume mowing at 3.5–4″ as active growth returns; sharpen blades before the first spring cut.
• Begin a balanced, split-application fertility program as growth fully activates—avoid heavy single doses.
• Pre-emergent weed control before summer annual grasses germinate; see our spring pre-emergent guide.
• Inspect south-facing edges and driveways for early chinch bug activity as temperatures rise.

Summer (peak growth + pest and disease pressure)

• Mow every 7–10 days at 3.5–4.5″; don’t let the lawn get ahead of you and then cut back hard.
• Morning-only irrigation—evening or overnight watering in summer humidity is the fastest path to gray leaf spot.
• Inspect hot sunny edges monthly for chinch bug signs; early action prevents the kind of damage that requires re-sodding.
• Avoid heavy nitrogen during wet summer months; it drives gray leaf spot pressure significantly.

Fall (slow-down + disease transition window)

• Reduce mowing frequency as growth slows with shorter days and cooler nights.
• Reduce irrigation frequency as evapotranspiration drops; over-watering in fall creates ideal large patch conditions.
• Stop nitrogen applications before active growth stalls—late-season nitrogen drives large patch vulnerability into winter.
• Good window for soil testing and correcting potassium, pH, or micronutrient deficiencies before dormancy.

Winter (semi-dormancy)

• Floratam slows significantly in South Florida winters; some color fading is normal, not disease.
• Significantly reduce irrigation; overwatering dormant or semi-dormant St. Augustine promotes large patch and root decline.
• Do not apply nitrogen during dormancy or semi-dormancy.
• Continue mowing if active growth is still showing; don’t let the lawn get tall and then cut back hard when growth resumes in spring.

Watering (weeks 0–3)

• Days 0–7: Keep consistently moist; avoid puddling and dry seams.
• Days 8–14: Taper frequency as roots set; check under corners and concrete edges.
• Days 15–21: Transition to deep, less frequent watering (~1″/week including rain).

Mowing

• First mow when rooted (~10–14 days); never mow if seams still lift.
• Maintain ~3.5–4.5″—the most important single habit for Floratam health.
• Sharp blades prevent tip burn and the browning that dull mowers produce on coarse blades.

Nutrition & health

• Moderate, split-application fertility; avoid heavy nitrogen in hot humid months.
• Pests: inspect hot sunny edges for chinch bugs monthly in summer. See the chinch bug guide.
• Diseases: gray leaf spot (summer) and large patch (winter) are both managed with morning-only watering and correct mow height.
