Flat Lick, Kentucky, sits in USDA hardiness zone 7a — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
Well-matched crops include cabbage, hazelnut, california poppy, and collard greens, and the gap between "grows in the area" and "grows in your yard" is closed by soil, sun, and drainage.
Even in Flat Lick, no two yards are alike.

What this means for growing in Flat Lick
Each reading below is measured for Flat Lick itself — here is what it means for a garden here, and the move an experienced grower makes about it.

Season length
MeasuredFlat Lick runs about 220 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.

Winter hardiness
MeasuredFlat Lick 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 Flat Lick is in
Flat Lick sits in the Central Appalachians — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Flat Lick's own centroid rather than borrowed from Knox County.
What Grows in Flat Lick
Every plant below cleared Flat Lick's own zone 7a and its 220-day season. Each card opens that plant's Kentucky profile. How we score.






























Is it too late to plant in Flat Lick?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Mar 2; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 30 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 5 — 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.

A note from Gnorman
What an experienced grower watches for around here
In and around Flat Lick, two things run higher than the national average within ~10 miles of Flat Lick — PFAS (3 sites) and Underground Storage Tanks (143 sites). That's not a problem with your land — it's information about it.
PFAS: PFAS (per- and polyfluoroalkyl substances) are called "forever chemicals" because they do not biodegrade.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Test irrigation water source — this is the primary pathway for PFAS to reach garden crops.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside Flat Lick
Everything above resolves to Flat Lick as a whole — one PHZM band and one 28°F frost record, read across 3K 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 Flat Lick
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 Flat Lick’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 Flat Lick
When does frost risk typically end in Flat Lick?
The last hard freeze (28°F) in Flat Lick typically lands around Mar 30, 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 20.
When is the first frost in Flat Lick?
The first hard freeze (28°F) in Flat Lick typically arrives around Nov 5, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Oct 22, so the watching starts about Oct 6 — about 220 days after the spring freeze cleared.
How long is the growing season in Flat Lick?
Measured between 28°F hard freezes, Flat Lick sees about 220 frost-free days — roughly Mar 30 through Nov 5, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 20 to Oct 22, about 185 days.
Is the soil safe to grow vegetables in Flat Lick?
The federal record around Flat Lick is a meaningful one — 175 documented sites, mostly Underground Storage Tanks entries (143), the nearest Underground Storage Tanks record about 0.6 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 Flat Lick?
From about Oct 6 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 Nov 5 (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 Nov 5. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
Everything above is measured at Flat Lick's scale — its 7a band and its 220-day season. Your yard writes its own version of Flat Lick's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
