Most lawn advice online is written for northern grasses on a northern growing season. In Jupiter, Palm Beach Gardens and the rest of Palm Beach County, turf grows nearly year-round, and the schedule that keeps a lawn thick here looks very different.
The short answer: weekly in summer, bi-weekly in winter
From roughly April through October, when heat and afternoon storms drive rapid growth, South Florida lawns need weekly mowing. From November through March, growth slows enough that bi-weekly service usually keeps the lawn looking sharp without stressing it.
The reason to hold that schedule comes down to one rule: never remove more than one third of the blade in a single cut. Skip a week in July and you are forced to scalp the lawn to bring it back to height — which shocks the plant, exposes the soil to sun, and opens the door to weeds.
Cut height matters more than frequency
Cutting too short is the single most common mistake we see on Palm Beach County lawns. Short turf has short roots, and short roots dry out fast in sandy Florida soil. Taller blades shade the soil, hold moisture, and crowd out weeds before they establish.
- St. Augustine — 3.5 to 4 inches. The most common lawn grass in our area and the one that suffers most from a short cut.
- Zoysia — 2 to 2.5 inches. Tolerates a slightly tighter cut but still prefers the higher end of that range in summer.
- Bahia — 3 to 4 inches. Common on larger lots and acreage, and forgiving as long as it is not scalped.
Signs your lawn is being mowed wrong
- White or brown frayed blade tips a day after service — the blade is dull
- Visible thatch and exposed soil after a cut — the lawn is being scalped
- Weeds appearing in thin patches — the canopy is too short to shade them out
- Ruts or tire tracks in the same lines every week — the pattern is never alternated
Rainy season changes the math
During the summer rainy season, growth can outrun even a weekly schedule. When that happens, the right move is a slightly higher first pass followed by a second cut a few days later, rather than one aggressive cut that scalps the lawn.
Our crews alternate mowing direction on every visit, keep decks sharp, and adjust height as the season shifts. That combination is what keeps a lawn dense enough to shrug off weeds on its own.
