Each reading below is measured for Gibsonton itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Winter hardiness
MeasuredGibsonton sits in USDA hardiness zone 10a.
The zone sets which perennials, shrubs, and fruit trees live through an average winter here — a plant rated for a colder zone is a safe bet, one rated warmer needs winter protection or gets treated as an annual.
Match perennials and fruit to the zone before you buy, so nothing you plant is a gamble against the cold.

The kind of country Gibsonton is in
Gibsonton sits in the Southern Coastal Plain — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Gibsonton's own centroid rather than borrowed from Hillsborough County.

Your land is one point inside Gibsonton
Everything above resolves to Gibsonton as a whole — one PHZM band and one 28°F frost record, read across 8K acres. Your parcel is one point inside that footprint. Slope, tree cover, a low spot that pools cold air, and what is in the soil are all resolved at the address, and none of them are visible at town scale. That is the honest boundary of this page, and the reason the next step is a reading of your own ground rather than a better local average.

How we know this about Gibsonton
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this town’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals, with the labelled statewide window where none resolves; boundaries and acreage from US Census TIGER/Line 2025; the contamination records from the federal sources named in their beats above. Soil is not read at town grain anywhere on this page — there is no town-resolution survey in our data, which is why you will find no soil grid here rather than a statewide one wearing a local label. The resolution ledger below names every figure this page inherited.
Common questions about Gibsonton
Is it too late to plant in Gibsonton?
No — Gibsonton has no 28°F killing freeze in the 30-year station record, so the growing season is year-round and there is no last-frost date to wait for. Planting is paced by rainfall, heat and daylength instead of by frost: start heat-lovers any month, and time cool-season crops (lettuce, brassicas, peas) for the cooler, wetter half of the year or for higher ground. Succession sowing every few weeks works all year, so the limit is what you can keep watered and harvested, not the calendar.
When does frost risk typically end in Gibsonton?
It doesn't — Gibsonton records no 28°F killing freeze at all across the 1991–2020 station record, so there is no spring frost date to plant after. Cold still matters with elevation: the higher you garden, the cooler the nights, and a few tropical crops sulk below about 60°F even where they never freeze.
How long is the growing season in Gibsonton?
Year-round — the 1991–2020 station record for Gibsonton contains no 28°F killing freeze, so there is no season to measure between freezes. What paces planting instead is heat, rainfall and daylength: the hottest, wettest stretch is the hard part for cool-season crops, not winter. Elevation is the one real exception — the higher you garden, the colder the nights get.
Is the soil safe to grow vegetables in Gibsonton?
The federal record around Gibsonton runs heavier than most — 1,623 documented sites, mostly Underground Storage Tanks entries (861), the nearest Nitrate record about 0.3 miles out — so test the soil before planting food in the ground, and raised beds with clean imported soil grow well in the meantime. Even here, proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what's recorded and where.
Everything above is measured at Gibsonton's scale — its 10a band and its no killing freeze on record. Your yard writes its own version of Gibsonton's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
