The South Florida Lawn Care Schedule, Month by Month

November – January: The Slow Gear

Growth eases as nights cool. Mowing stretches to every two weeks, and irrigation becomes the main event: this is the dry season, when the lawn actually depends on your sprinkler system — typically one or two deep waterings on your county's allowed days, adjusted for the fronts that bring occasional rain. Watch the rain sensor earn its keep on the wet weeks and skip cycles after storms.

January and February are the year's planning window: soil tests if the lawn has been pale or patchy without explanation, irrigation repairs you have been postponing, and the pre-emergent weed application timed before spring weeds germinate. Late winter is also when a tired lawn's renovation math should happen — sod establishes beautifully as spring warmth arrives, and booking before the spring rush is how you get a date.

• ▸Mowing: every two weeks, keeping St. Augustine at 3.5–4 inches
• ▸Irrigation: dry-season rhythm — deep and infrequent on allowed days
• ▸Late winter: pre-emergent weed control, soil test, irrigation repairs

February – April: The Feeding Window Opens

Spring is South Florida lawn care's main event. As growth restarts, the year's most important fertilization lands — in Miami-Dade it must be completed before the blackout begins in mid-May, so March and April feedings are the program's anchor. Palms get fed on their own schedule in the same window. Pre-emergent applied in late winter starts paying off now, and post-emergent cleanup handles the weeds that slipped through.

Mowing cadence tightens back to weekly as growth accelerates toward the end of April. This is also the season to walk the irrigation zone by zone before the dry weeks bite: broken heads and dry arcs found in April are cheap; the same problems found by the dead patch in June are not. Hurricane prep sneaks onto the list by May — canopy and palm work is best scheduled before June, not after the first storm warning.

Mid-May – September: Blackout, Deluge, and Bug Season

From mid-May through September, Miami-Dade's fertilizer blackout bans nitrogen and phosphorus applications — the program shifts to mowing discipline, iron for color, and vigilance. Rainy-season growth is relentless: weekly mowing, edging that cannot skip, and beds that fill with weeds between visits. Lawns should not be mowed saturated; a good service flexes a day around deluges rather than rutting wet turf.

This is chinch bug high season — watch the hot, sunny edges along driveways and pavement for yellowing patches that spread despite watering, and check the thatch at the patch margin for the insects themselves. Fungal disease (large patch and friends) rides the same months, fed by wet nights: water early in the morning only, never in the evening. Storm season runs underneath everything — after a storm, clear debris off the lawn within days; smothered wet grass under a frond pile dies fast, and note any irrigation damage while the yard is being cleaned.

• ▸No nitrogen or phosphorus in Miami-Dade from mid-May through September
• ▸Weekly mowing; never mow saturated turf
• ▸Chinch bug checks on hot pavement edges all summer
• ▸Water at dawn only — evening watering feeds fungus

October: The Second Feeding and the Reset

The blackout lifts at the end of September, and October carries the fall fertilization — the feeding that rebuilds what the rainy season spent and carries root strength into the dry months. Growth begins its slow decline; mowing can start stretching out late in the month. October is also mulch and bed season: refresh mulch before the dry months so beds hold what moisture the season gives, and plant new landscaping now — roots establish through the mild winter and the garden is ready for spring.

By late October the irrigation schedule flips fully to dry-season settings, and it is worth a deliberate controller check: rainy-season habits — relying on rain — end here, and lawns lost in the dry season are usually lost to a system nobody reprogrammed, not to the weather.

The Rules Underneath Every Month

Three principles survive every month on this calendar. First, mowing height never changes with the season — St. Augustine stays at 3.5 to 4 inches all year; scalping in any month is damage, not tidiness. Second, water follows the grass's signals and the county rules, deeply and infrequently, at dawn. Third, every problem on this calendar — chinch bugs, fungus, weeds, dry arcs — is cheapest in the month it starts, which is why the schedule pairs every task with watching.
