How Often to Mow Your Lawn in Florida: Season-by-Season Guide
In South Florida, mow your lawn every 7 days from April to October, when heat and rain speed up growth, and every 10–14 days from November to March. Bermuda may need a cut every 5 days in summer. Whatever the season, never remove more than one-third of the blade height in a single mowing.
The One-Third Rule
Before marking your calendar, there is a biological principle every Florida homeowner should know: the one-third rule. Never cut more than one-third of the total height of the grass blade in a single session.
If you cut too much (a practice known as "scalping"), you stress the roots, leave the soil exposed to the intense sun—which evaporates moisture—and make it easier for weeds to take over.
Mowing Frequency by Season
Florida’s climate dictates the pace. We can divide the year into two main phases:
Growing Season (April to October) With the arrival of rain and intense heat, the lawn enters a phase of hyperactivity.
Frequency: Every 7 days.
Pro Tip: Fast-growing varieties, like Bermuda, may require attention every 5 days to stay dense and low. If you wait two weeks in July, you will likely violate the one-third rule when trying to bring it back to the ideal height.
Transition and Winter Season (November to March) While grass in South Florida never goes fully dormant, growth slows down significantly due to shorter days and cooler night temperatures.
Frequency: Every 10 to 14 days.
Northern Variation: In North Florida (where frosts can occur), you may only need to mow once a month or simply stop if the grass ceases to grow entirely.
Recommended Mowing Height by Grass Type
It is essential to understand that every type of grass has its own ideal "stature." Just as you wouldn't use the same settings to prune a bush as you would to cut flowers, adjusting your mower blade height according to the variety you have at home is vital for its health. If you mow too low, you could weaken the roots and leave them exposed to disease; conversely, a cut at the correct height allows the garden to grow stronger, retain moisture better, and look consistently green and lush.
Pro Tip: Keeping the grass slightly higher (within the recommended range) helps the roots grow deeper, making your lawn more resistant to typical Florida droughts.
HOA Rules in Deerfield Beach and Coconut Creek
If you live in a community with a Homeowners Association (HOA), mowing frequency is not just a biological suggestion, but a contractual obligation. Most HOAs in cities like Deerfield Beach or Coconut Creek require that the lawn does not exceed 4 or 5 inches. Neglecting it during the heavy rain weeks of summer can result in non-compliance notices within just a few days.
Tips for a Better Cut
Sharp Blades: Florida’s heat encourages fungi. A dull blade "tears" the grass instead of cutting it, leaving an open wound that invites disease. Sharpen your blades at least twice a year.
Avoid Wet Grass: Mowing after an afternoon thunderstorm (so common here) compacts the grass and can clog the machine, besides creating an uneven cut.
The Best Time: Ideally, mow in the mid-morning (8:00 AM – 10:00 AM), once the dew has evaporated but before the sun is at its strongest.
Frequently Asked Questions About Mowing in Florida
What height should I mow St. Augustine grass in Florida?
Keep St. Augustine at 3.5 to 4 inches, especially in summer. Taller grass shades the soil, holds moisture and grows deeper roots. Learn more about why grass dies in Florida summers.
Do I need to mow in winter in South Florida?
Yes. South Florida grass never goes fully dormant, so plan on mowing every 10 to 14 days from November to March.
What is the best time of day to mow?
Mid-morning, around 8 to 10 AM, after the dew dries and before the strongest sun.
Can I mow right after it rains?
It's better to wait. Wet grass clumps, clogs the mower and leaves an uneven cut, and it can compact the soil.
How tall can my grass get under HOA rules?
Many HOAs in Deerfield Beach and Coconut Creek require grass to stay under 4 to 5 inches. In the rainy season that can mean weekly mowing to avoid violation notices.
