Immokalee, Florida, sits in USDA hardiness zone 10a — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
Expect okra, meyer lemon, california poppy, and artichoke to be strong candidates here; the deciding factors on any one parcel stay local — soil, sun, and drainage.
Even in Immokalee, no two yards are alike.

What this means for growing in Immokalee
Each reading below is measured for Immokalee itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredImmokalee runs about 330 days between hard freezes — close to year-round growing.
Frost is rarely the limit here; winter plantings are as real as summer ones, and the harder question is which crops shrug off the summer heat.
Grow cool-season crops through the mild winter, and choose heat-tolerant varieties for the summer beds.
NOAA 1991–2020 Climate Normals
Winter hardiness
MeasuredImmokalee 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 Immokalee is in
Immokalee sits in the Southern Coastal Plain — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Immokalee's own centroid, and it is not what its county reads: Collier County is mostly Southern Florida Coastal Plain. The wider page above you is answering a different question about different ground.

Is it too late to plant in Immokalee?
Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Jan 1; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Jan 19 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 15 — long-season crops need about 90 days of runway, quick greens only 30. With almost year-round growing weather, timing is about heat and rainfall more than frost — some bench is always in play.

A note from Gnorman
What an experienced grower watches for around here
In and around Immokalee, Nitrate runs higher than the national average — 120 sites within ~10 miles of Immokalee. That's not a problem with your land — it's information about it.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
Test well water for nitrate if you rely on a private well for irrigation (EPA standard: 10 mg/L).

Your land is one point inside Immokalee
Everything above resolves to Immokalee as a whole — one PHZM band and one 28°F frost record, read across 15K 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 Immokalee
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 at Immokalee’s own record; 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 Immokalee
When does frost risk typically end in Immokalee?
The last hard freeze (28°F) in Immokalee typically lands around Jan 19, per NOAA 1991–2020 climate normals — earlier than the light-frost dates most charts quote. That marks the hard freeze, not the last light frost — lighter frosts keep biting past it, which is why tender transplants here wait until about Feb 9.
When is the first frost in Immokalee?
The first hard freeze (28°F) in Immokalee typically arrives around Dec 15, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Dec 1, so the watching starts about Nov 15 — about 330 days after the spring freeze cleared.
How long is the growing season in Immokalee?
Measured between 28°F hard freezes, Immokalee sees about 330 frost-free days — roughly Jan 19 through Dec 15, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 9 to Dec 1, about 295 days.
Is the soil safe to grow vegetables in Immokalee?
The federal record around Immokalee is a meaningful one — 223 documented sites, mostly Nitrate entries (120), the nearest Brownfields record about 0.1 miles out — so a soil test before new food beds is a sensible precaution here, not a reason to hold back from growing. Remember that proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what sits where.
How do I protect my plants from frost in Immokalee?
From about Nov 15 the job here turns from planting to protecting — the last start even a 30-day crop can finish. As the season closes around the first 28°F hard freeze near Dec 15 (NOAA 1991–2020 climate normals), three moves buy time: row cover or an old sheet over tender plants on still, clear nights; water the soil the afternoon before a freeze, so it holds warmth overnight; and harvest tomatoes, peppers and basil before Dec 15. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
