Florida's warm-season grasses thrive when you cut them at the right height and often enough to follow the one-third rule — never remove more than one-third of the grass blade in a single mowing. Cutting too short stresses the turf, exposes the soil to weed seeds, and weakens roots so the lawn can't handle Florida's heat and dry spells.
Recommended mowing heights for Florida grasses
Different grass types need different heights. St. Augustine, the most common South Hillsborough lawn, prefers the tallest cut. Here's where to set your mower deck:
- St. Augustine (Floratam, Palmetto, etc.): 3.5–4 inches — never below 3 inches
- Zoysia: 1.5–2.5 inches — cut lower than St. Augustine
- Bermuda: 0.75–1.5 inches — the lowest cut, ideal for tight, dense turf
- Bahia: 3–4 inches — common in rural Wimauma pastures and acreage
How often to mow
During peak growing season (April–October), most Florida lawns need weekly mowing to keep up with growth and respect the one-third rule. In cooler or drier months, bi-weekly may be enough. Mowing frequency should match growth — if the grass is growing, it's time to mow.
Why sharp blades matter
Dull mower blades tear the grass instead of cutting it cleanly. Torn tips turn brown and gray, giving the whole lawn a dull cast, and the open wounds invite fungal disease. We sharpen blades daily on our commercial mowers — a detail that makes a visible difference in lawn color and health.
The bottom line
Mow high, mow often, and keep blades sharp. Pair consistent mowing with proper irrigation and your Florida lawn will stay thick, green, and resilient through every season. Not sure your grass type or the right height? We'll assess it free during a property evaluation.
