Quick answer: Tampa sits in subtropical USDA zone 9b, which is effectively frost-free, so the lawn grows nearly year-round and the calendar is built around heat and the summer rains rather than winter. Spring (Mar–May) is for the first mow-downs, the first fertilizing once the lawn greens up, and pre-emergent weed control. Summer (Jun–Sep) is peak growth and disease season under a fertilizer ban and water restrictions — mow often, scout for chinch bugs and fungus, and feed nothing with N or P. Fall (Oct–Nov) reopens the fertilizing window and is ideal for planting. Winter (Dec–Feb) is the slow season for cleanup, mulching, and dormant pruning. Source: UF/IFAS. Updated 2026-06-16.
What is the month-by-month lawn calendar for Tampa?
Because Tampa is zone 9b and warm-season grasses never truly go dormant, the year is organized around feeding windows, the summer fertilizer ban, and water restrictions rather than around frost. The table below is the at-a-glance version; the sections that follow explain each season.
| Season | Key Tampa tasks |
|---|---|
| Spring (Mar–May) | First fertilizing once green; pre-emergent weed control; resume regular mowing; check irrigation |
| Summer (Jun–Sep) | No N/P fertilizer (ban); mow frequently; scout chinch bugs & fungus; follow water restrictions; iron for color |
| Fall (Oct–Nov) | Fall fertilizing after ban lifts; best planting/sod window; overseed only if desired; lower mowing frequency |
| Winter (Dec–Feb) | Slow growth; cleanup, mulch, dormant pruning; minimal watering; watch rare cold snaps |

What should I do for my Tampa lawn in spring?
Spring (March through May) is the wake-up and set-up season. Once the grass is fully green and actively growing — usually by April — apply the first fertilizing of the year with a slow-release nitrogen product, well before the June 1 ban. This is also the window for a pre-emergent herbicide to head off summer weeds like crabgrass and a good time to service the irrigation system and confirm the rain sensor works before the dry late-spring stretch. Resume regular mowing at the proper height for your grass, and address any winter weeds while the lawn is filling back in.

How do I care for a Tampa lawn in summer?
Summer (June through September) is peak growth, peak disease, and the most regulated season. The June 1–September 30 fertilizer ban means no nitrogen or phosphorus — use iron for color instead — and water restrictions govern irrigation, so let the frequent rains do most of the work and only supplement on your allowed day. Mow often, since the grass grows fast, and keep blades sharp. This is prime time for chinch bugs on St. Augustine and for fungal diseases like gray leaf spot and large patch in the humidity, so scout weekly and treat problems early rather than feeding the lawn, which only makes disease worse.

What about fall and winter lawn care in Tampa?
Fall (October–November) is the reward season: the fertilizer ban lifts October 1, so a fall feeding with slow-release nitrogen helps the lawn recover from summer stress, and the cooler, still-warm soil makes it the best window of the year to plant, sod, or install landscape beds. Growth slows, so you can mow less often. Winter (December–February) is Tampa’s quiet season — the lawn barely grows, watering needs drop sharply, and the work shifts to cleanup, fresh mulch, and dormant pruning of shrubs and trees. Keep an eye on the occasional cold snap, since a rare frost can briefly brown warm-season turf that recovers in spring.

Frequently asked questions about the Tampa landscaping calendar
What growing zone is Tampa in? Tampa is in subtropical USDA hardiness zone 9b, which is effectively frost-free and supports near year-round lawn growth.
When should I fertilize my lawn in Tampa? In spring once the lawn is green (around April) and again in fall after the ban lifts (October or November). No nitrogen or phosphorus fertilizer June 1 through September 30.
When is the best time to plant in Tampa? Fall is the best planting and sodding window, when the soil is still warm but the brutal summer heat has eased. Spring is a strong second choice.
Do I need to water my Tampa lawn in winter? Very little. Growth slows and rainfall plus cooler temperatures usually suffice; overwatering in winter invites disease.
When are chinch bugs and lawn disease worst in Tampa? The hot, humid summer months (roughly June through September) are peak season for chinch bugs on St. Augustine and for fungal diseases.
Does grass go dormant in Tampa? Warm-season grasses slow dramatically in winter but rarely go fully dormant in zone 9b, and a rare frost may briefly brown them before spring recovery.
