Zones Fit — Chill Unconfirmed
Hardiness allows pine nut here — the zones overlap. Winter chill is the harder question, and our chill-hour figure for this plant is not corroborated against a published source, so we do not publish a verdict on it. The chill line below shows what Florida typically banks; treat it as a starting point and confirm with a local Extension office.

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 pine nut 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 Pine Nut Stands in Florida
Pine Nut is rated for zones 4–8 — a cold floor USDA puts at -30 to -20°F. No Florida county sits inside it, so in open ground this is a grown-under-cover plant here rather than a bed plant — which is a statement about Florida winters, not about pine nut.

Too little winter chill rather than too much cold — a low-chill selection is what changes 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.

When to Plant Pine Nut 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 pine nut, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether pine nut 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.
Timing tuned to sub-state frost dates — Holmes County, not the statewide average.
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.
Growing Season Fit
The zone check says pine nut survives winter in part of Florida, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Pine Nut wants 365+ frost-free days; a typical Florida site sees ~320 (NOAA Regional Climate Centers ACIS, 1991-2020) — 45 days short of what it needs. A typical Florida season does not carry this crop to harvest outdoors, and a gap that size is not one an earlier sowing date or a faster cultivar closes; growing it here means growing it under cover.
Growing degree days
Pine Nut needs ~1500 GDD (base 50°F) to ripen. The state median runs ~7743 GDD (from PRISM 1991-2020 climate normals), so Florida's typical season clears that easily.
Chill hours
Pine Nut requires ~400 chill hours (32-45°F dormancy window). Florida typically banks ~0 chill hours per winter, short of this plant's requirement — fruit set may suffer in mild years without a low-chill cultivar.
GDD and chill-hour figures are computed from PRISM 1991-2020 monthly climate normals; frost-free days from NOAA Regional Climate Centers ACIS, 1991-2020. Each is the state median across its counties (P25/P75 span the within-state spread). Hardiness-zone range is USDA PHZM 2023.
Soil + Drainage Fit
Pine Nut likes near-neutral soil (pH 4.5-6.5). 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 5 and 5.5 — 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, raised beds or amendment with compost solve it.
Your land, not the state average
SSURGO maps about 44.6% of Florida as poorly or somewhat-poorly drained, and the class flips parcel to parcel. Pine Nut tolerates drought well, so wet feet — not dry spells — is its real risk here — your soil map unit, not the state average, is the real answer.

Before you plant pine nut 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 pine nut 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 — 76,189 documented sites across 7 of the 9 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 with clean imported soil grow well almost anywhere in the meantime.

- •Underground tanks leak petroleum as they age — near a former filling station, test the soil.
- •Near a brownfield, raised beds of imported soil give your food clean ground.
- •On a private well, test for nitrates: above 10 mg/L the water needs treatment before irrigating.

What Else to Consider for Pine Nut 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
Growing pine nut here specifically
Pine Nut roots run deep and prefer pH 4.5–6.5, but drainage comes first here: SSURGO maps about 44.6% of Florida as poorly or somewhat-poorly drained, and wet ground rots its crown before pH ever matters.
Plant pine nut on a raised, gravel-amended berm so water drains fast and the crown stays dry. How to handle it →
What to actually do about these — and the constraints that apply to every Florida grower, not just pine nut — is covered on the Florida growing guide.
Timing shifts within Florida
Florida isn't one climate. In Holmes County, the last hard freeze (28°F) holds until about Feb 20 — roughly 16 days later than the recorded state median — so plant pine nut to your county's window, not the statewide date.
Pine Nut needs about 365 days of frost-free season to complete its cycle. 11 of Florida’s 67 counties give it that outright. The tightest that does is Brevard County at 365 frost-free days — 0 to spare. Below that line you are transplanting or extending the season, not direct-sowing.
Across Florida’s 67 counties the frost-free season runs from 281 days in Holmes County to 365 days in Sarasota County — a spread of 84 days, which is why a single statewide planting date misleads. The median Florida county sees 320 frost-free days, which is 45 days short of what pine nut needs — so on a typical Florida parcel this is a transplant-or-protect crop, not a direct-sow one.
County last-freeze dates and frost-free day counts: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F freeze (earlier than the folk 32°F "last frost"). Pine Nut's 365-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.

Common Questions About Growing Pine Nut in Florida
When can I plant Pine Nut 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 Pine Nut, 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 Pine Nut grown in across Florida?
Florida spans USDA hardiness zones 8b-12a (USDA ARS PHZM 2023). Pine Nut carries a range of zones 4-8, 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). Pine Nut needs 365+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date. In cooler counties like Holmes, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Pine Nut native to Florida?
Pine Nut is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in Florida. It can still earn a place in a Florida garden — the zone comparison above tells you whether it will thrive.
How should I amend the soil for Pine Nut in Florida?
Pine Nut prefers pH 4.5-6.5 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.
