Edmondson, Arkansas, sits in USDA hardiness zone 8a — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
These conditions suit cabbage, fig, california poppy, and collard greens — a starting list any specific site will trim or extend with its own soil, sun, and drainage.
Even in Edmondson, no two yards are alike.

What this means for growing in Edmondson
Each reading below is measured for Edmondson itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsEdmondson runs about 264 days between hard freezes (read from Crittenden County, the closest normal to Edmondson) — 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
MeasuredEdmondson sits in USDA hardiness zone 8a.
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 Edmondson is in
Edmondson sits in the Mississippi Alluvial Plain — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Edmondson's own centroid rather than borrowed from Crittenden County.

Is it too late to plant in Edmondson?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Feb 6; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 6 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 25 — 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.

A note from Gnorman
What an experienced grower watches for around here
In and around Edmondson, two things run higher than the national average within ~10 miles of Edmondson — Toxics Release Inventory (37 sites) and Superfund (5 sites). It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
Toxics Release Inventory: TRI facilities report annual chemical releases to air, water, and land.
Superfund: Superfund sites represent the most severe contamination in the federal system.
Check prevailing wind direction — downwind parcels face higher exposure than upwind or crosswind locations.
Commission professional soil testing before any food production (test for heavy metals, VOCs, and SVOCs).

Your land is one point inside Edmondson
Everything above resolves to Edmondson as a whole — one PHZM band, read across 2K acres, with hard-freeze dates borrowed from Crittenden County’s record because no 30-year normal resolves at this town’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 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 Edmondson
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 Crittenden 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 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 Edmondson
When does frost risk typically end in Edmondson?
The last hard freeze (28°F) in Edmondson typically lands around Mar 6, 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 27.
When is the first frost in Edmondson?
The first hard freeze (28°F) in Edmondson typically arrives around Nov 25, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 11, so the watching starts about Oct 26 — about 264 days after the spring freeze cleared.
How long is the growing season in Edmondson?
Measured between 28°F hard freezes, Edmondson sees about 264 frost-free days — roughly Mar 6 through Nov 25, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 27 to Nov 11, about 229 days.
Is the soil safe to grow vegetables in Edmondson?
The federal record around Edmondson is a meaningful one — 339 documented sites, mostly Underground Storage Tanks entries (169), the nearest Underground Storage Tanks record about 0.3 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 Edmondson?
From about Oct 26 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 25 (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 25. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
