Okfuskee County, in Oklahoma, sits in USDA hardiness zone 7b — room for a real mix of vegetables, fruit, and perennials matched to the local frost calendar.
These conditions suit cabbage, prickly pear, california poppy, and collard greens — a starting list any specific site will trim or extend with its own soil, sun, and drainage.

Heat and winter chill in Okfuskee County
Across a year, Okfuskee County accumulates about 4,855 growing degree days above 50°F, about 135 more than the middle Oklahoma county — ahead of 51 of Oklahoma’s 77 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 1,783 hours below 45°F, 136 fewer than the Oklahoma middle of 1,919. 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 Okfuskee County
Across Okfuskee County, the ground is predominantly Mollisols, where Stephenville, Eram, and Darnell are the most extensive named soil series. The soil is generally well drained with a fine sandy loam surface. Topsoil pH runs about 5.8–6.5, slightly acidic. Rainfall drains through hydrologic group D soils.

How the ground varies across Okfuskee County
The USDA soil survey maps 42% of Okfuskee County as well drained — but another 56% drains differently: 22% somewhat poorly drained, 22% moderately well drained.
Stephenville is the most extensive named soil at 10% of mapped acres, then Eram (10%) and Darnell (7%).
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 Okfuskee County
Each reading below is measured for Okfuskee 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 Okfuskee County are well drained, in hydrologic group D — 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 Okfuskee County runs about pH 5.8–6.5, close to neutral.
This is the range most vegetables prefer — one correction you probably do not have to make, which is genuinely good news for a new bed.
Keep it there with compost rather than lime or sulfur, and only amend if your own soil test says otherwise.
USDA NRCS SSURGO
Season length
MeasuredOkfuskee County runs about 242 days between hard freezes — a long growing season.
There is slack for succession plantings and slow-finishing crops: many vegetables can be sown twice, and the heat-lovers have time to ripen fully.
Plan a second sowing of quick crops after the first comes out, and use the fall window most gardeners let sit idle.
NOAA 1991–2020 Climate Normals
Winter hardiness
MeasuredOkfuskee County sits in USDA hardiness zone 7b.
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.

Okfuskee County sits in the Cross Timbers — EPA Level III, inside the wider Great Plains. One consistent ecological setting across the whole county.
What Grows in Okfuskee County
We scored all 1,086 plants against Okfuskee County's own USDA zone 7b and its own 242-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 Oklahoma profile.
Is it too late to plant in Okfuskee County?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Feb 17; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 17 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 14 — long-season crops need about 90 days of runway, quick greens only 30. A long window like this one runs successions deep into fall — and even its last weeks take quick greens and garlic.
What gets applied to farmland in Okfuskee County
USGS estimates 36,211 lb of 2,4-d on Okfuskee County farmland in 2019, its largest by weight, ahead of Triclopyr (15,815 lb) and Glyphosate (12,342 lb).

What the federal record shows across Okfuskee County — and how to grow with it.
We checked the federal record across Okfuskee County — 84 documented sites across 6 of the 9 source types we track.
The most significant on record: 1 Superfund site (none NPL-listed). Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
There's a meaningful federal record across Okfuskee County — worth a look before you plant food, not a reason to hold back from growing. Proximity to a documented site is information, not a diagnosis of any one yard. A soil test before new food beds is the sensible precaution here, and the map shows exactly which sites sit where, so you can see what's actually near you.
Sources: EPA, USGS — 1.8M documented sites tracked nationwide across 9 federal source types.

What an experienced grower watches for around here
In and around Okfuskee County, Underground Storage Tanks runs higher than the national average — 77 sites across Okfuskee County. That's not a problem with your land — it's information about it.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside Okfuskee County
Everything above resolves to Okfuskee County as a whole — one PHZM band and one county frost record, read across 396K 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 Okfuskee 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 Okfuskee County carries no record of its own, the figure is inherited and labelled — the resolution ledger below names each.
Common questions about Okfuskee County
When does frost risk typically end in Okfuskee County?
The last hard freeze (28°F) in Okfuskee County typically lands around Mar 17, 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 Apr 7.
How long is the growing season in Okfuskee County?
Measured between 28°F hard freezes, Okfuskee County sees about 242 frost-free days — roughly Mar 17 through Nov 14, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 7 to Oct 31, about 207 days.
Is the soil safe to grow vegetables in Okfuskee County?
The federal record around Okfuskee County is a meaningful one — 84 documented sites, mostly Underground Storage Tanks entries (77), the nearest Underground Storage Tanks record about 0.8 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.
Everything above is measured at Okfuskee County's scale — its 7b band and its 242-day season. Your yard writes its own version of Okfuskee County's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
