Florida’s lawn season runs nearly year-round, which means your Florida mowing schedule barely gets a break. Warm-season grasses push hard from March through November, and the specific grass under your mower determines every setting on your deck.
St. Augustine and Bahia are Florida’s two dominant turf grasses. They respond to heat, drought, and shade differently enough that a single mowing plan cannot cover both. The Florida Lawn Care Guide has the full annual schedule for both grass types; the Florida mowing guide maps out regional timing; this post focuses on the mowing heights and timing that keep each one performing through Florida’s long growing season.
St. Augustine Florida Mowing Schedule
St. Augustine is the most widely planted turf in Florida. It spreads by stolons, needs moderate moisture, and cannot tolerate scalping. Keep the leaf blade in its optimal height range so the canopy shades out weeds without forcing the grass to recover from a stress cut.
Blade sharpness is critical with this grass. A dull blade tears the wide St. Augustine leaf rather than cutting it cleanly, leaving ragged tips that turn tan and open the turf to fungal problems during humid Florida summers. Sharpen at least three times during the growing season; see how to sharpen lawn mower blades for the right technique and frequency.
Recommended height: 3.5–4 inches for standard varieties; 2.5–3 inches for semi-dwarf cultivars like Palmetto.
| Month | Growth Rate | Frequency | Deck Height |
|---|---|---|---|
| January–February | Slow | As needed, 1–2x per month | 4 in |
| March–April | Picking up | Weekly | 3.5–4 in |
| May–June | Active | Every 5–7 days | 3.5–4 in |
| July–August | Peak | Every 5–7 days | 4 in |
| September–October | Slowing | Weekly | 3.5–4 in |
| November–December | Slow | Every 2–3 weeks | 4 in |
Raise the deck to 4 inches during peak summer heat. The taller canopy reduces soil moisture loss and prevents sunscald, which shows up as yellowing patches after consecutive hot, sunny weeks.
Never remove more than one-third of the blade in a single pass. If heavy rain pushes growth past that threshold, mow twice within a few days rather than scalping back in one cut.
Bahia Grass Mowing Schedule
Bahia handles drought, poor soil, and infrequent mowing better than any other Florida grass. It grows from both seeds and rhizomes and produces tall seed heads quickly. Mow it regularly enough to keep those seed heads from dominating the lawn’s appearance.
Recommended height: 3–4 inches.
| Month | Growth Rate | Frequency | Deck Height |
|---|---|---|---|
| January–February | Dormant | Rarely needed | 3–4 in |
| March–April | Starting | Every 10–14 days | 3.5–4 in |
| May–June | Active | Weekly | 3–4 in |
| July–August | Peak | Every 5–7 days | 3–4 in |
| September–October | Slowing | Every 10–14 days | 3.5–4 in |
| November–December | Slow | As needed | 4 in |
Bahia seed heads extend well above the leaf canopy. Mowing on the shorter end of the range controls them without stressing the grass; once peak summer passes, raise the deck back up.
One detail that catches homeowners off guard: the wiry seed head stems dull mower blades faster than most grass types. Budget for blade sharpening at least twice during the summer push, not just at the start of the season.
Deck Height Settings and Blade Maintenance
Bahia stays in the 3–4 inch range, while St. Augustine runs a touch higher: 3.5–4 inches for standard varieties and 2.5–3 inches for semi-dwarf types. The consequences of getting it wrong are different. Scalping St. Augustine below 2.5 inches exposes the stolons and triggers a stress response that takes weeks to correct. Bahia is more forgiving, but thin out the canopy consistently and you invite weeds into the gaps.
The mowing height guide covers deck adjustment mechanics across common push and riding mower platforms, including how to verify your actual cut height against the deck indicator rather than trusting the dial.
For both grasses, a clean cut that minimizes open tissue matters more in Florida than in cooler climates. High humidity and a long growing season create persistent fungal pressure. Dull blades in that environment are a liability, not just an inconvenience.
Fertilizing Florida Warm-Season Grass
St. Augustine and Bahia have different nitrogen appetites, and Florida’s sandy soils leach nutrients faster than heavier clay types. Split applications beat a single heavy feeding either way.
St. Augustine: Feed 4–6 times from March through October. A 15-0-15 or similar slow-release formulation keeps the deep green color without triggering excess top growth that invites chinch bugs. Look for controlled-release nitrogen, added iron for color, and no phosphorus, which Florida’s sandy soils don’t need.
Even distribution matters as much as product selection. A calibrated broadcast spreader prevents the streaky green-yellow pattern that shows up within two weeks of an uneven feeding. A unit like the Scotts Turf Builder EdgeGuard DLX Broadcast Spreader holds enough for up to 15,000 square feet and lets you dial in the setting most St. Augustine granular products list on the bag.
Bahia: Feed 3–4 times per year with a 16-4-8 or balanced high-nitrogen formula. Bahia tolerates lighter inputs than St. Augustine and still produces an acceptable turf. Time applications after mowing, not before, so the grass is actively growing when it takes up nutrients rather than recovering from the cut.
Common Mistakes That Cost Florida Homeowners a Healthy Lawn
Mowing wet grass. Florida summers mean afternoon thunderstorms almost daily. Mowing immediately after rain compacts the soil and tears wet turf unevenly. Waiting a few hours makes a measurable difference in cut quality.
Breaking the one-third rule during rainy stretches. When grass grows fast in July and August, cutting hard to buy time puts maximum stress on the root system at the worst moment. Two moderate cuts in the same week beats one aggressive cut every time.
Holding the same deck height year-round. Dropping to 3 inches in November because the lawn looks cleaner at that height leaves St. Augustine exposed going into winter. Keep the deck up through dormancy so the canopy protects the crown.
Leaving Bahia clippings after heavy seed-head cuts. Bahia seed heads left on the surface can germinate and introduce variability into an otherwise uniform turf. Bag or blow off clippings after any mow that takes down a significant seed-head flush.
Skipping mid-season blade sharpening. A dull blade in August, when humidity is highest and growth is fastest, sets up dollar spot and gray leaf spot by September. The connection between blade quality and fungal pressure is direct in Florida’s climate.
