Florida is not one climate
Florida’s winter-low ladder runs across 67 counties, from zone 8.5 in Holmes County to zone 10.5 in Palm Beach County. That is 20°F between the two counties’ average coldest night — the difference between tree tomato overwintering in the ground and coming under cover.
The middle half of 67 counties runs 9–10 zones, with a median of 9.5 zones — a 2-zone span end to end.
Measured across 67 Florida counties. USDA PHZM 2023, per county. Quartiles are order statistics — every figure shown is a value a real county recorded, not an interpolation. Your own site sits somewhere inside this range; a parcel report resolves where.
Where in Florida Fits Best
Tree Tomato is rated for zones 10–13 — a cold floor USDA puts at 30 to 40°F. Against Florida’s 67 counties that band holds in 20 of them, and the line runs at Brevard County (zone 10a), the coldest county still inside it.

County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. A zone is a 10°F band of average annual extreme minimum temperature, so the floor above is the band the plant's rating denotes, not a single measured kill point. Slope, shelter and cold-air drainage routinely move a site half a zone either way from its county figure — which is the part only your address resolves.
Even within Florida's zones 8b-12a, county microclimates differ enough to change what thrives. These counties carry the closest zone match for tree tomato (USDA PHZM 2023):

When to Plant Tree Tomato in Florida
The frost window
Across Florida, the last spring hard freeze (28°F) clears between Jan 25 and Feb 10, and the first fall hard freeze lands between Dec 7 and Dec 18 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 300-day window you can count on — up to 327 days on a mild site in a kind year. That marks the hard freeze, not the last light frost, so tender transplants usually wait another 2-3 weeks.
Winter standing
Florida runs as cold as USDA zone 8, and no sourced winter-hardiness floor is on record for tree tomato, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether tree tomato is a permanent planting or a replant-every-spring crop for you turns on your own zone within Florida; check its hardiness range against that before treating it as long-lived ground.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: Growable Ground Plant Database — frost-free days from FAO ECOCROP, days to harvest from university Extension production guides, and growing-degree-day and chill-hour minimums that are compilation estimates rather than published figures. Your site's own frost dates can run earlier or later than the state range — a parcel report pins them down.
Soil + Drainage Fit
Tree Tomato likes near-neutral soil (pH 5.8-7.5). That's the common-ground band across Florida's sandy and muck (everglades) — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 6.3 and 7 — worth knowing before you decide whether a Florida soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Florida site is heavier clay or sits in a low spot, a raised bed lifts the roots above wet ground, or work in compost.

Before you plant tree tomato for food
Anything you grow to eat takes up what is in the ground it grows in, so what is on record near you is worth knowing before tree tomato goes in. What follows is Florida’s documented federal record at state scale — a screening signal, not a soil test, and not a statement about any one lot.
Safe to Grow Here?
What the federal record shows across Florida — and how to grow with it.
We checked the federal record across Florida — 43,701 documented sites across 6 of the 8 source types we track.
The most significant on record: 602 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Florida carries one of the heavier federal records we track — and that's not a verdict on your yard. Proximity to a documented site is information, not a diagnosis: nothing here says any particular parcel is affected. It does earn one concrete step — before food beds go in the ground, a professional soil test tells you exactly what you're working with, and raised beds of imported, lab-tested soil grow well almost anywhere in the meantime.

Know Before You Grow
- •Underground tanks leak petroleum as they age — near a former filling station, test the soil.
- •TRI facilities report what they release. Check the wind — downwind beds catch more of it.
- •Near a brownfield, a raised bed of imported, lab-tested soil lowers contact with the ground; it does not remove it.

What Else to Consider for Tree Tomato in Florida
Zone compatibility tells you about winter cold survival — but Florida growers also need to think about:
Sandy soils drain too fast and hold few nutrients — frequent fertilization needed
Humidity drives fungal diseases (powdery mildew, black spot, rust)
Hurricane season (June-November) can destroy plantings
Nematodes are a serious pest in sandy FL soils
What to actually do about these — and the constraints that apply to every Florida grower, not just tree tomato — is covered on the Florida growing guide.
Where in Florida Tree Tomato Is Zone-Hardy
Tree Tomato is rated for USDA zones 10–13. 20 of Florida’s 67 counties fall inside that band. The coldest that does is Brevard County at zone 10a. 47 counties sit below the plant’s zone 10 floor, where an unprotected plant is relying on snow cover and a mild year. Where you are in Florida decides this one.
Across those 67 counties Florida’s winter-low ladder runs from zone 8b in Holmes County to zone 10b in Palm Beach County — 2 USDA zones of spread, which is 20°F between the two counties’ average coldest night of the year. That is why a statewide hardiness answer is where you start and not where you finish.
The planting window moves with it. Holmes County holds its last hard freeze (28°F) until about Feb 20, while Okeechobee County is clear by Jan 18 — 33 days apart. Set tree tomato out on your county’s date, not the state’s.

Pollinator + Wildlife Value
Tree Tomato draws native bees (moderate value). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, tree tomato can only work that bloom inside Florida's frost window — roughly 320 days, opening after the last 28°F freeze (Jan 25 - Feb 10) and closing at the first (Dec 7 - Dec 18), per NOAA Regional Climate Centers ACIS, 1991-2020. Pollinator value: We haven't confirmed this against a published source yet.

Common Questions About Growing Tree Tomato in Florida
When can I plant Tree Tomato in Florida?
Florida's last spring hard freeze (28°F) clears between Jan 25 and Feb 10, and the first fall hard freeze lands between Dec 7 and Dec 18 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Tree Tomato, so this page does not state whether it overwinters in Florida and publishes no fall establishment date for it — check its hardiness range against your own zone before treating it as a permanent planting.
What hardiness zone is Tree Tomato grown in across Florida?
Florida spans USDA hardiness zones 8b-12a (USDA ARS PHZM 2023). Tree Tomato carries a range of zones 10-13, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Florida site have?
A typical Florida site sees ~320 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Tree Tomato needs 270+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
How should I amend the soil for Tree Tomato in Florida?
Tree Tomato prefers pH 5.8-7.5 and well (dry spells) drainage (FAO ECOCROP). That sits in the common-ground band across Florida soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
Will Tree Tomato actually grow on my specific land in Florida?
State-level zone + climate data is a sketch. A Growable Ground parcel report scores tree tomato against your address's mapped soil pH, drainage, sun, and frost-date data drawn from USDA SSURGO, NOAA, and PRISM — not state averages.
