Red Devil, Alaska, sits in USDA hardiness zone 2b — room for a real mix of vegetables, fruit, and perennials matched to the local frost calendar.
These conditions suit cabbage, potato, rhubarb, and kale — a starting list any specific site will trim or extend with its own soil, sun, and drainage.

What this means for growing in Red Devil
Each reading below is measured for Red Devil itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsRed Devil runs about 142 days between hard freezes (read from Bethel Census Area, the closest normal to Red Devil) — a short growing season.
Long-maturing crops like melons, sweet potatoes, and winter squash can run out of runway before the first hard freeze, ripening late or not at all.
Lead with fast-maturing varieties, and stretch the season on both ends with cold frames, low tunnels, or a greenhouse.
NOAA 1991–2020 Climate Normals
Winter hardiness
MeasuredRed Devil sits in USDA hardiness zone 2b.
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.

Is it too late to plant in Red Devil?
Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Apr 12; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 10 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Sep 29 — long-season crops need about 90 days of runway, quick greens only 30. When the window is tight, the fall moves are quick ones — baby greens, radishes, and garlic set for next season.

What an experienced grower watches for around here
In and around Red Devil, Mining runs higher than the national average — 25 sites within ~10 miles of Red Devil. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
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 Red Devil
Everything above resolves to Red Devil as a whole — one PHZM band, read across 16K acres, with hard-freeze dates borrowed from Bethel Census Area’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 Red Devil
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 Bethel Census Area’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 Red Devil
When does frost risk typically end in Red Devil?
The last hard freeze (28°F) in Red Devil typically lands around May 10, 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 May 31.
When is the first frost in Red Devil?
The first hard freeze (28°F) in Red Devil typically arrives around Sep 29, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 15, so the watching starts about Aug 30 — about 142 days after the spring freeze cleared.
How long is the growing season in Red Devil?
Measured between 28°F hard freezes, Red Devil sees about 142 frost-free days — roughly May 10 through Sep 29, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 31 to Sep 15, about 107 days.
Is the soil safe to grow vegetables in Red Devil?
The federal record around Red Devil runs heavier than most — 26 documented sites, mostly Mining entries (25), the nearest Mining record about 0.7 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 gardeners stretch the season in Red Devil?
With about 142 frost-free days between hard freezes, Red Devil rewards the classic extension moves: floating row cover buys roughly two to four extra weeks at each shoulder — on this season that is a working window nearer 170 to 198 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the May 10 hard-freeze normal stretches the season without touching the calendar.
