Okahumpka, Florida, sits in USDA hardiness zone 9b — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
These conditions suit okra, meyer lemon, california poppy, and artichoke — a starting list any specific site will trim or extend with its own soil, sun, and drainage.
Even in Okahumpka, no two yards are alike.

What this means for growing in Okahumpka
Each reading below is measured for Okahumpka itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsOkahumpka runs about 328 days between hard freezes (read from Lake County, the closest normal to Okahumpka) — 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.

Winter hardiness
MeasuredOkahumpka sits in USDA hardiness zone 9b.
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 Okahumpka is in
Okahumpka sits in the Southern Coastal Plain — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Okahumpka's own centroid rather than borrowed from Lake County.

Is it too late to plant in Okahumpka?
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 26 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 20 — long-season crops need about 90 days of runway, quick greens only 30. And with a calendar this mild, the honest answer is that planting barely stops — winter opens seasons colder regions never see.

What an experienced grower watches for around here
In and around Okahumpka, PFAS runs higher than the national average — 6 sites within ~10 miles of Okahumpka. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
PFAS: PFAS (per- and polyfluoroalkyl substances) are called "forever chemicals" because they do not biodegrade.
Test irrigation water source — this is the primary pathway for PFAS to reach garden crops.

Your land is one point inside Okahumpka
Everything above resolves to Okahumpka as a whole — one PHZM band, read across 158 acres, with hard-freeze dates borrowed from Lake County’s record because no 30-year normal resolves at this town’s own centroid. 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 Okahumpka
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 Lake County’s record, because none resolves here; 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 Okahumpka
When does frost risk typically end in Okahumpka?
The last hard freeze (28°F) in Okahumpka typically lands around Jan 26, 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 16.
When is the first frost in Okahumpka?
The first hard freeze (28°F) in Okahumpka typically arrives around Dec 20, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Dec 6, so the watching starts about Nov 20 — about 328 days after the spring freeze cleared.
How long is the growing season in Okahumpka?
Measured between 28°F hard freezes, Okahumpka sees about 328 frost-free days — roughly Jan 26 through Dec 20, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 16 to Dec 6, about 293 days.
Is the soil safe to grow vegetables in Okahumpka?
The federal record around Okahumpka is a meaningful one — 440 documented sites, mostly Underground Storage Tanks entries (270), the nearest Underground Storage Tanks record under a tenth of a mile 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 Okahumpka?
From about Nov 20 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 20 (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 20. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
