Bergman, Arkansas, sits in USDA hardiness zone 7b — a zone band wide enough that plant choice, not possibility, is the interesting question.
A short list that earns its place here — cabbage, prickly pear, california poppy, and collard greens — with any one site's soil, sun, and drainage making the final cut.
Even in Bergman, no two yards are alike.
A low spot, a south-facing slope, or a stand of trees moves the frost date and sun across a single Bergman lot. Enter your address and we'll score 1,086 plants against your land's actual soil, sun, and frost.

What this means for growing in Bergman
Each reading below is measured for Bergman itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredBergman runs about 243 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
MeasuredBergman 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.
USDA PHZM 2023
The kind of country Bergman is in
Bergman sits in the Ozark Highlands — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Bergman's own centroid rather than borrowed from Boone County.

Is it too late to plant in Bergman?
For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Feb 20; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 20 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 18 — long-season crops need about 90 days of runway, quick greens only 30. With a season this long, “too late” mostly means “switch crops” — second sowings and a full fall garden are the norm, with garlic closing the year.

A note from Gnorman
What an experienced grower watches for around here
In and around Bergman, Mining runs higher than the national average — 79 sites within ~10 miles of Bergman. Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Mining: Mining sites — both historic and active — can leach heavy metals (arsenic, lead, cadmium, mercury) into soil and water for centuries after operations cease.
Test soil for heavy metals (lead, arsenic, cadmium, mercury) — this is essential near any mining site.

Your land is one point inside Bergman
Everything above resolves to Bergman as a whole — one PHZM band and one 28°F frost record, read across 835 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 Bergman
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 Bergman’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 Bergman
When does frost risk typically end in Bergman?
The last hard freeze (28°F) in Bergman typically lands around Mar 20, 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 10.
When is the first frost in Bergman?
The first hard freeze (28°F) in Bergman typically arrives around Nov 18, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 4, so the watching starts about Oct 19 — about 243 days after the spring freeze cleared.
How long is the growing season in Bergman?
Measured between 28°F hard freezes, Bergman sees about 243 frost-free days — roughly Mar 20 through Nov 18, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 10 to Nov 4, about 208 days.
Is the soil safe to grow vegetables in Bergman?
The federal record around Bergman runs heavier than most — 281 documented sites, mostly Underground Storage Tanks entries (138), the nearest Brownfields record about 0.3 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.
How do I protect my plants from frost in Bergman?
From about Oct 19 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 18 (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 18. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
Everything above is measured at Bergman's scale — its 7b band and its 243-day season. Your yard writes its own version of Bergman's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
