How Often Should You Mow Your Lawn in Central Florida?

If you live in Central Florida, you already know that grass here doesn't take a break. Our warm, humid climate keeps lawns growing for most of the year, which means your mowing schedule looks a lot different from what homeowners deal with up north. Here's a straightforward, season-by-season breakdown so you always know when it's time to fire up the mower.

The Short Answer

During the growing season (roughly March through October), plan to mow once a week. In the cooler months (November through February), you can cut back to every two to three weeks, depending on how your lawn is growing.

That said, a few things can shift that schedule, including your grass type, how much rain we're getting, and whether you're irrigating.

Season by Season

Spring (March - May)

This is when Central Florida lawns wake up and start growing fast. Warmer temperatures and spring rains fuel a surge in growth. Weekly mowing is the standard, and during especially rainy stretches, you may need to bump that up to twice a week.

Summer (June - September)

Peak growing season. Between the heat, humidity, and afternoon thunderstorms, grass grows aggressively. Expect to mow weekly at minimum. Weeks with heavy rainfall can push some lawns to need a second cut.

Fall (October - November)

Growth starts to slow as temperatures cool down. You can transition to mowing every 10 to 14 days. Most lawn professionals in Central Florida make this switch around early November.

Winter (December - February)

Your lawn won't stop growing entirely (unlike in North Florida), but it slows way down. Mowing every two to three weeks is typically enough to keep things looking clean. Some weeks you may just need a pass to mulch up oak leaves.

The One-Third Rule

No matter when you mow, follow the one-third rule: never remove more than one-third of the grass blade in a single mowing. This is the most widely recommended mowing guideline in turfgrass management, originally established through USDA research and reinforced by the University of Florida's Institute of Food and Agricultural Sciences (UF/IFAS).

Why does it matter? Grass produces its energy through photosynthesis in the leaf blades. Cutting too much at once reduces the plant's ability to feed itself, weakens the root system, and opens the door to weeds, pests, and disease.

In practical terms: if you maintain your St. Augustine at 4 inches, mow before it reaches 6 inches. If you let it get away from you, raise the mower to the highest setting and bring it down gradually over multiple cuts rather than scalping it all at once.

Know Your Grass Type

The type of grass you have determines both your ideal mowing height and how often you'll need to cut. Here are the most common grass types in Central Florida and their recommended mowing heights, per UF/IFAS guidelines:

• St. Augustine (the most common in our area): 3.5 to 4 inches
• Bahia: 3 to 4 inches
• Zoysia: 2 to 2.5 inches (coarse varieties)
• Bermuda: 0.5 to 1.5 inches

St. Augustine grows quickly during the warm months and needs consistent weekly mowing to stay healthy. Bahia is lower maintenance overall, but sends up tall seedheads that need regular trimming. Zoysia grows more slowly than St. Augustine, so you may get away with slightly less frequent cuts.

Leave the Clippings

If you're following the one-third rule and mowing at the right frequency, leave your grass clippings on the lawn. They break down quickly and return nitrogen, phosphorus, and potassium back into the soil. Research from Oregon State University has shown that returning clippings with a mulching mower can reduce fertilizer needs by nearly half. UF/IFAS confirms that clippings handled this way do not contribute to thatch buildup.

This is an easy win: less waste, less fertilizer cost, and a healthier lawn.

A Few More Tips

Keep your blades sharp. Dull mower blades tear the grass instead of cutting it cleanly, leaving ragged edges that turn brown and invite disease. Most manufacturers recommend sharpening every 20 to 25 hours of use.

Mow when the grass is dry. Wet grass clumps together, cuts unevenly, and can clog your mower. In Central Florida, mornings after the dew dries or late afternoons are usually best.

Don't mow too short. It's tempting to cut low so you can go longer between mows, but this weakens roots and stresses the lawn, especially during our hot summers. Mow at the highest recommended height for your grass type.

When in Doubt, Watch Your Lawn

The best mowing schedule is one that responds to how your lawn is actually growing, not just the calendar. If the grass is growing fast, mow more often. If growth has stalled during a cool snap or dry spell, skip a week. Your lawn will tell you what it needs.
