Red Dog Mine, Alaska, sits in USDA hardiness zone 3b — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
Expect cabbage, potato, rhubarb, and kale to be strong candidates here; the deciding factors on any one parcel stay local — soil, sun, and drainage.
Even in Red Dog Mine, 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 Red Dog Mine 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 Red Dog Mine
Each reading below is measured for Red Dog Mine itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsRed Dog Mine runs about 127 days between hard freezes (read from Northwest Arctic Borough, the closest normal to Red Dog Mine) — 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.

Winter hardiness
MeasuredRed Dog Mine sits in USDA hardiness zone 3b.
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.

Plants matched to Red Dog Mine's USDA zones 3b, ordered by how much hardiness margin each has here — the ones with room to spare at both ends of this town's band lead. Each links to its full growing profile.
Is it too late to plant in Red Dog Mine?
Too late for some crops, right on time for others — a growing season is a sequence, not a deadline. Cool-season crops can go in from around Apr 26; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 24 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Sep 28 — long-season crops need about 90 days of runway, quick greens only 30. In a season this compact, fast finishers and cold-hardy greens do the late work, and garlic tucked in before the freeze repays you next summer.

Know Before You Grow
- •Mine waste leaches heavy metals. Test for lead, arsenic and cadmium before growing food here.
- •Near a brownfield, raised beds of imported soil give your food clean ground.
- •A Superfund listing means federally documented contamination. Test soil and water before planting edibles nearby.

Your land is one point inside Red Dog Mine
Everything above resolves to Red Dog Mine as a whole — one PHZM band, read across 44K acres, with hard-freeze dates borrowed from Northwest Arctic Borough’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 Dog Mine
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 Northwest Arctic Borough’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 Dog Mine
When does frost risk typically end in Red Dog Mine?
The last hard freeze (28°F) in Red Dog Mine typically lands around May 24, 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 Jun 14.
When is the first frost in Red Dog Mine?
The first hard freeze (28°F) in Red Dog Mine typically arrives around Sep 28, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 14, so the watching starts about Aug 29 — about 127 days after the spring freeze cleared.
How long is the growing season in Red Dog Mine?
Measured between 28°F hard freezes, Red Dog Mine sees about 127 frost-free days — roughly May 24 through Sep 28, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 14 to Sep 14, about 92 days.
Is the soil safe to grow vegetables in Red Dog Mine?
The federal record around Red Dog Mine is a meaningful one — 11 documented sites, mostly Mining entries (8), the nearest Toxics Release Inventory record about 1.1 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 gardeners stretch the season in Red Dog Mine?
With about 127 frost-free days between hard freezes, Red Dog Mine 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 155 to 183 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the May 24 hard-freeze normal stretches the season without touching the calendar.
