Fayette County, in Kentucky, sits in USDA hardiness zone 7a — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
Expect cabbage, hazelnut, california poppy, and collard greens to be strong candidates here; the deciding factors on any one parcel stay local — soil, sun, and drainage.
Fayette County lies within the Kentucky Bluegrass — a regional growing area with its own character.

Heat in Fayette County
Across a year, Fayette County accumulates about 3,658 growing degree days above 50°F, about 2 fewer than the middle Kentucky county — ahead of 59 of Kentucky’s 120 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.

Soil in Fayette County
Across Fayette County, the ground is predominantly Alfisols, where Bluegrass, Maury, and Lowell are the most extensive named soil series. The soil is generally well drained with a silt loam surface. Topsoil pH runs about 5.8–7.0, slightly acidic. Rainfall drains through hydrologic group C soils.

How the ground varies across Fayette County
The USDA soil survey maps 84% of Fayette County as well drained — but another 12% drains differently: 9% moderately well drained, 2% somewhat poorly drained.
Bluegrass is the most extensive named soil at 23% of mapped acres, then Maury (22%) and Lowell (14%).
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 Fayette County
Each reading below is measured for Fayette 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 Fayette County are well drained, in hydrologic group C — 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 Fayette County runs about pH 5.8–7.0, 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
MeasuredFayette County runs about 227 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
MeasuredFayette County sits in USDA hardiness zone 7a.
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 Fayette County is in
Fayette County sits in the Interior Plateau — EPA Level III, inside the wider Eastern Temperate Forests. One consistent ecological setting across the whole county.
What Grows in Fayette County
We scored all 1,086 plants against Fayette County's own USDA zone 7a and its own 227-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 Kentucky profile.
Is it too late to plant in Fayette County?
Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Feb 27; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 27 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 9 — long-season crops need about 90 days of runway, quick greens only 30. Here the season winds down slowly: late sowings, a real autumn harvest, and garlic in the ground before the first hard freeze.

What the federal record shows across Fayette County — and how to grow with it.
We checked the federal record across Fayette County — 978 documented sites across 7 of the 9 source types we track.
The most significant on record: 11 Superfund sites (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 Fayette 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.

What an experienced grower watches for around here
In and around Fayette County, Underground Storage Tanks runs higher than the national average — 735 sites across Fayette County. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around 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 Fayette County
Everything above resolves to Fayette County as a whole — one PHZM band and one county frost record, read across 182K 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 Fayette 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 Fayette County carries no record of its own, the figure is inherited and labelled — the resolution ledger below names each.
Common questions about Fayette County
When does frost risk typically end in Fayette County?
The last hard freeze (28°F) in Fayette County typically lands around Mar 27, 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 17.
How long is the growing season in Fayette County?
Measured between 28°F hard freezes, Fayette County sees about 227 frost-free days — roughly Mar 27 through Nov 9, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 17 to Oct 26, about 192 days.
Is the soil safe to grow vegetables in Fayette County?
The federal record around Fayette County is a meaningful one — 978 documented sites, mostly Underground Storage Tanks entries (735), the nearest Underground Storage Tanks 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.
