Florida’s Grass Growing Season, Region by Region
Florida’s warm-season grasses grow most actively once soil temperatures hold consistently above roughly 65°F, which generally lines up with a growing season running from spring through early fall — commonly cited as March through October. How that plays out varies noticeably by region:
- South Florida (roughly Zones 10-11): Grass grows actively nearly year-round, with growth only slowing modestly during the shorter winter days rather than going fully dormant.
- Central Florida (roughly Zone 9): Active growth typically ramps up in March or April and slows into a semi-dormant state from around December through February.
- North Florida (roughly Zone 8): Sees the most pronounced winter slowdown, with growth often pausing more fully from November through March.
These are general patterns rather than fixed dates — an unusually warm or cool winter can shift things in either direction, so it’s worth watching your own lawn’s growth rather than treating any calendar date as absolute. Florida’s vegetable garden follows a related but distinct fall rhythm, shaped more by waiting out summer heat than by frost — see this state-by-state fall planting guide for the Florida vegetable-garden section.
When Does Grass Start Growing Again in Spring?
Grass “starts back growing” once soil warms past the point of dormancy, generally in the March-to-April range across most of Florida, though South Florida may see little true dormancy to begin with. Spring (commonly cited as March through May) is generally considered the single best window for planting new sod, plugs, or seed, since soil is warming, rainfall is increasing but not yet at peak summer intensity, and the lawn has a full growing season ahead to establish roots before winter. A secondary planting window often opens in fall (roughly October-November) as summer heat and heavy rain taper off while soil is still warm enough for root growth.
Specific grass types have their own best planting windows — for example, some sources suggest Bahiagrass tolerates summer planting better than St. Augustinegrass, which is more commonly planted in spring or fall. Since several of Florida’s main lawn grasses (St. Augustine, Zoysia) are installed as sod rather than seed, and timing recommendations vary somewhat by source, it’s reasonable to treat any specific month-by-month planting table as a general guide rather than an exact rule for your yard.

Florida Mowing Schedule by Season
Mowing frequency scales with the growing season:
- Spring (March-May): Mow roughly every 7-10 days as rising temperatures and spring rain restart growth.
- Summer (June-September): Peak growth; mowing commonly steps up to roughly every 5-7 days given intense sun and frequent rain.
- Fall (October-November): Growth begins slowing with cooler fronts; mowing frequency often drops to roughly every 10-14 days.
- Winter (December-February): Warm-season grasses go semi-dormant across Central and North Florida, and mowing often drops to roughly every 2-3 weeks, or pauses entirely during the coolest stretches.
Do you cut grass year-round in Florida? In South Florida, yes — mowing generally continues through the winter, often on a weekly or biweekly schedule, since growth doesn’t fully stop. In Central and especially North Florida, mowing typically slows substantially or pauses during the coolest weeks of winter as grass goes semi-dormant, then resumes as temperatures rise in spring.
The 1/3 Rule and Mowing Heights by Grass Type
What is the 1/3 rule of mowing? It’s the general guidance that you should never remove more than one-third of a grass blade’s height in a single mowing. Cutting more than that at once can stress the plant and shock the root system, particularly in hot weather, which is why letting grass grow a bit taller between mows (rather than scalping it back down to a preferred height) is usually the safer approach.
Recommended mowing heights vary by grass type. Figures commonly cited for Florida’s main lawn grasses:
| Grass type | Typical mowing height |
|---|---|
| St. Augustine | 2.5-4 inches |
| Bahia | 2.5-4 inches |
| Zoysia | 1-2.5 inches |
| Bermuda | 0.5-1.5 inches |
St. Augustine and Bahia, the two most common grasses across much of Florida, generally do best kept on the taller end of their range during summer heat, since taller grass shades the soil, retains moisture better, and keeps roots somewhat cooler.
Easiest Grass Types to Grow in Florida
Bahiagrass is frequently described as one of the easier, more forgiving warm-season grasses to establish in Florida, partly because it can be grown from seed (unlike St. Augustine or Zoysia, which require sod or plugs) and tolerates a wider range of soil conditions and lower maintenance than some alternatives. It’s not necessarily the best-looking or densest option — St. Augustine is often preferred for a more manicured, uniform lawn — but for straightforward establishment and lower input, Bahia is commonly recommended, especially for larger properties where sod would be costly.
Winter Lawn Care: What to Skip, What to Keep Doing
What month shouldn’t you mow your lawn? There’s no single Florida-wide answer, since it depends on region and that year’s weather, but the general principle is to stop mowing once your grass has gone dormant or semi-dormant and growth has essentially stopped — commonly sometime in December in Central and North Florida, continuing into February. Mowing dormant, brown grass serves little purpose and can do more harm (scalping, soil compaction from equipment) than good.
Should I cut my grass in Florida during the winter? In South Florida, where growth doesn’t fully stop, continuing to mow — just less frequently — generally makes sense. In Central and North Florida, it’s reasonable to scale back mowing substantially or stop altogether during the coldest weeks, resuming once new growth appears in spring. What to skip through winter: heavy nitrogen fertilization (it can interfere with dormancy and increase cold-injury risk) and aggressive dethatching. What to keep doing, if needed: occasional deep watering during extended dry stretches, since even dormant grass has some root-level water needs, and spot-treating any active winter weeds. Our regional lawn care schedules article covers similar seasonal tradeoffs for other regions, including Texas and Tennessee.
FAQ
What’s the earliest you can mow your lawn in Florida? There’s no fixed earliest date — it depends on when your specific lawn breaks dormancy and resumes active growth, which varies by region (South Florida may barely go dormant at all) and by that year’s temperatures. The practical rule is to mow once growth resumes rather than on a fixed calendar date.
What month does grass start back growing? Generally March in much of Florida, sometimes earlier in South Florida and later (into April) in North Florida, though this shifts year to year with weather.
What is the easiest grass to grow in Florida? Bahiagrass is commonly cited as one of the easier, lower-maintenance options, partly because it can be seeded rather than requiring sod, though St. Augustine remains the more common choice where a denser, more manicured look is the priority.
Do you cut grass year-round in Florida? In South Florida, generally yes, often on a reduced winter schedule. In Central and North Florida, mowing often slows substantially or pauses during the coolest weeks as grass goes semi-dormant.
