Humnoke, Arkansas, sits in USDA hardiness zone 8b — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
Growers here do well with cabbage, fig, california poppy, and collard greens — with the usual caveat that any single yard's soil, sun, and drainage cast the deciding vote.
Even in Humnoke, 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 Humnoke 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 Humnoke
Each reading below is measured for Humnoke itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsHumnoke runs about 275 days between hard freezes (read from Lonoke County, the closest normal to Humnoke) — 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.

Winter hardiness
MeasuredHumnoke sits in USDA hardiness zone 8b.
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 Humnoke is in
Humnoke sits in the Mississippi Alluvial Plain — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Humnoke's own centroid rather than borrowed from Lonoke County.

Is it too late to plant in Humnoke?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Jan 30; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 27 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 29 — 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.

Your land is one point inside Humnoke
Everything above resolves to Humnoke as a whole — one PHZM band, read across 201 acres, with hard-freeze dates borrowed from Lonoke County’s record because no 30-year normal resolves at this city’s own centroid. 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 city 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 Humnoke
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this city’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals at Lonoke County’s record, because none resolves here; 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 city grain anywhere on this page — there is no city-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 Humnoke
When does frost risk typically end in Humnoke?
The last hard freeze (28°F) in Humnoke typically lands around Feb 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 Mar 20.
When is the first frost in Humnoke?
The first hard freeze (28°F) in Humnoke typically arrives around Nov 29, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 15, so the watching starts about Oct 30 — about 275 days after the spring freeze cleared.
How long is the growing season in Humnoke?
Measured between 28°F hard freezes, Humnoke sees about 275 frost-free days — roughly Feb 27 through Nov 29, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 20 to Nov 15, about 240 days.
Is the soil safe to grow vegetables in Humnoke?
The federal record around Humnoke is light — 23 documented sites across the 9 federal source types we checked, mostly Underground Storage Tanks entries (15), the nearest Underground Storage Tanks record under a tenth of a mile out — and proximity to a documented site is information, not a diagnosis of any one yard. Growing food here starts from a strong position; a soil test before new food beds settles any site-specific question.
How do I protect my plants from frost in Humnoke?
From about Oct 30 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 29 (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 29. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
