Lake County, in Florida, sits in USDA hardiness zone 9b — room for a real mix of vegetables, fruit, and perennials matched to the local frost calendar.
The conditions favor okra, meyer lemon, california poppy, and artichoke, among others — though every individual site edits that list with its own soil, sun, and drainage.
Lake County lies within the Central Florida Ridge — a regional growing area with its own character.

Lake County — the short answer

Heat and winter chill in Lake County
Across a year, Lake County accumulates about 7,843 growing degree days above 50°F, about 458 more than the middle Florida county — ahead of 40 of Florida’s 67 counties. Degree days are the heat a crop actually gets to work with — more of them is more room to ripen a long-season crop before the freeze closes the window.
Winter banks about 0 hours below 45°F, 36 fewer than the Florida middle of 36. Chill is what tells a fruit tree its dormancy is over, and it is set by climate rather than by anything you can build.

Soil in Lake County
Across Lake County, the ground is predominantly Entisols, where Candler, Myakka, and Tavares are the most extensive named soil series. The soil is generally excessively drained with a sand surface. Topsoil pH runs about 5.0–5.7, strongly acidic. Rainfall drains through hydrologic group A soils.

How the ground varies across Lake County
The USDA soil survey maps 26% of Lake County as excessively drained — but another 59% drains differently: 26% very poorly drained, 18% poorly drained.
Candler is the most extensive named soil at 20% of mapped acres, then Myakka (12%) and Tavares (5%).
Which of them your own lot sits on is a parcel question, not a county one. Check your address for the survey at your boundary.
What this means for growing in Lake County
Each reading below is measured for Lake County itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Drainage
MeasuredThe dominant soils across Lake County are excessively drained, in hydrologic group A — ground that drains quickly.
The upside is soil you can work early in spring and roots that never drown; the cost is that fast-draining ground dries out fast and leaches nutrients away before plants can use them.
Work in compost and mulch to hold moisture and feed, and water more often in short doses than deep and rarely.
USDA NRCS SSURGO
Surface pH
MeasuredTopsoil across Lake County runs about pH 5.0–5.7, on the acidic side.
Blueberries, potatoes, and rhododendrons thrive in it, but most vegetables start locking out nutrients below about pH 6.0 and grow pale and stunted no matter how much you feed them.
A measured lime application raises pH for the crops that need it — but test first, because the right rate depends on your own soil, not the county average.
USDA NRCS SSURGO
Wet ground
MeasuredAbout 39% of Lake County is mapped as hydric — wetland — soil.
If your lot falls in one of those pockets, a standard in-ground bed will fight waterlogging all season, and roots that need air will struggle.
Check how your own ground drains before you dig; raised beds or moisture-loving plantings turn a wet corner from a problem into a niche.
USDA NRCS SSURGO
Season length
MeasuredLake County runs about 328 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.

The kind of country Lake County is in
Lake County sits in the Southern Coastal Plain — EPA Level III, inside the wider Eastern Temperate Forests. One consistent ecological setting across the whole county.
What Grows in Lake County
We scored all 1,086 plants against Lake County's own USDA zone 9b and its own 328-day season between hard freezes, using the same matching engine that runs a full parcel report. These cleared both. Sun, soil pH and drainage vary lot by lot — those are the parcel questions below. Each card opens that plant's Florida profile.
Is it too late to plant in Lake County?
For most of the year, no — what changes is which crops still fit the days remaining. 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. Here the calendar nearly circles: cool-season crops take the winter shift, and the next window is always close.

Safe to Grow Here?
What the federal record shows across Lake County — and how to grow with it.
We checked the federal record across Lake County — 1,114 documented sites across 6 of the 9 source types we track.
The most significant on record: 8 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Lake County 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.
Sources: EPA, USGS — 1.8M documented sites tracked nationwide across 9 federal source types.

A note from Gnorman
What an experienced grower watches for around here
In and around Lake County, PFAS runs higher than the national average — 16 sites across Lake County. Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
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 Lake County
Everything above resolves to Lake County as a whole — one PHZM band and one county frost record, read across 611K 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 county 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 county average.

How we know this about Lake County
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at county grain; hard-freeze dates from NOAA 1991–2020 28°F normals at this county’s own record where one resolves, and the labelled statewide window where none does; soils from the USDA NRCS SSURGO survey, area-weighted across the county’s own map units; boundaries and acreage from US Census TIGER/Line 2025; the contamination and pesticide records from the federal sources named in their beats above. Where Lake County carries no record of its own, the figure is inherited and labelled — the resolution ledger below names each.
Common questions about Lake County
When does frost risk typically end in Lake County?
The last hard freeze (28°F) in Lake County 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.
How long is the growing season in Lake County?
Measured between 28°F hard freezes, Lake County 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 Lake County?
The federal record around Lake County runs heavier than most — 1,114 documented sites, mostly Underground Storage Tanks entries (677), the nearest Brownfields record about 0.9 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.
