Shungnak, Alaska, sits in USDA hardiness zone 1b — a zone band wide enough that plant choice, not possibility, is the interesting question.
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.
Even in Shungnak, 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 Shungnak 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 Shungnak
Each reading below is measured for Shungnak itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsShungnak runs about 127 days between hard freezes (read from Northwest Arctic Borough, the closest normal to Shungnak) — 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
MeasuredShungnak sits in USDA hardiness zone 1b.
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 Shungnak?
Almost never — the real question is what to plant next. 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. Short seasons reward decisiveness — quick-maturing varieties late, hardy greens under cover, and next year’s garlic in the ground before it closes.

Your land is one point inside Shungnak
Everything above resolves to Shungnak as a whole — one PHZM band, read across 5K acres, with hard-freeze dates borrowed from Northwest Arctic Borough’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 Shungnak
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 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 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 Shungnak
When does frost risk typically end in Shungnak?
The last hard freeze (28°F) in Shungnak 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 Shungnak?
The first hard freeze (28°F) in Shungnak 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 Shungnak?
Measured between 28°F hard freezes, Shungnak 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 Shungnak?
The federal record around Shungnak is light — 7 documented sites across the 9 federal source types we checked, mostly Mining entries (5), the nearest Nitrate record about 8.1 miles 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 gardeners stretch the season in Shungnak?
With about 127 frost-free days between hard freezes, Shungnak 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.
Everything above is measured at Shungnak's scale — its 1b band and its 127-day season. Your yard writes its own version of Shungnak's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
