Dermott, Arkansas, sits in USDA hardiness zone 8b — room for a real mix of vegetables, fruit, and perennials matched to the local frost calendar.
Among the crops suited to this profile: cabbage, fig, california poppy, and collard greens. The site-level story — soil, sun, drainage — decides the rest.
Even in Dermott, no two yards are alike.

What this means for growing in Dermott
Each reading below is measured for Dermott itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsDermott runs about 284 days between hard freezes (read from Chicot County, the closest normal to Dermott) — 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
MeasuredDermott 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 Dermott is in
Dermott sits in the Mississippi Alluvial Plain — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Dermott's own centroid rather than borrowed from Chicot County.

Is it too late to plant in Dermott?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Jan 22; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 19 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 30 — long-season crops need about 90 days of runway, quick greens only 30. And with a calendar this mild, the honest answer is that planting barely stops — winter opens seasons colder regions never see.

A note from Gnorman
What an experienced grower watches for around here
In and around Dermott, Nitrate runs higher than the national average — 78 sites within ~10 miles of Dermott. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
Test well water for nitrate if you rely on a private well for irrigation (EPA standard: 10 mg/L).

Your land is one point inside Dermott
Everything above resolves to Dermott as a whole — one PHZM band, read across 2K acres, with hard-freeze dates borrowed from Chicot 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 Dermott
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 Chicot 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 Dermott
When does frost risk typically end in Dermott?
The last hard freeze (28°F) in Dermott typically lands around Feb 19, 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 12.
When is the first frost in Dermott?
The first hard freeze (28°F) in Dermott typically arrives around Nov 30, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 16, so the watching starts about Oct 31 — about 284 days after the spring freeze cleared.
How long is the growing season in Dermott?
Measured between 28°F hard freezes, Dermott sees about 284 frost-free days — roughly Feb 19 through Nov 30, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 12 to Nov 16, about 249 days.
Is the soil safe to grow vegetables in Dermott?
The federal record around Dermott shows 127 documented sites, mostly Nitrate entries (78), the nearest Underground Storage Tanks record under a tenth of a mile out — a typical footprint for a growing area, and proximity to a documented site is information, not a diagnosis of any one yard. It's worth seeing which recorded sites sit closest to where you grow, and testing the soil before new food beds near any of them.
How do I protect my plants from frost in Dermott?
From about Oct 31 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 30 (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 30. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
