Beaver, Alaska, sits in USDA hardiness zone 1a — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
Among the crops suited to this profile: cabbage, potato, rhubarb, and kale. The site-level story — soil, sun, drainage — decides the rest.
Even in Beaver, 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 Beaver lot. Enter your address and we'll score 1,086 plants against your land's actual soil, sun, and frost.

Every figure names the dataset it came from. No 30-year normal resolves at this town’s own centroid, so the hard-freeze dates are Yukon-Koyukuk Census Area’s — the closest measured record, labelled as such rather than passed off as local.

What this means for growing in Beaver
Each reading below is measured for Beaver itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsBeaver runs about 118 days between hard freezes (read from Yukon-Koyukuk Census Area, the closest normal to Beaver) — 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
MeasuredBeaver sits in USDA hardiness zone 1a.
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.

What Grows in Beaver
Plants matched to Beaver's USDA zones 1a, 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 Beaver?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Apr 17; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 15 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Sep 10 — 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.
Environmental Check
No contamination sources found near Beaver
We checked 9 federal environmental databases and found no recorded contamination sites in this area. A clean starting point for growing.
Your land is one point inside Beaver
Everything above resolves to Beaver as a whole — one PHZM band, read across 13K acres, with hard-freeze dates borrowed from Yukon-Koyukuk 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 Beaver
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 Yukon-Koyukuk 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 Beaver
When does frost risk typically end in Beaver?
The last hard freeze (28°F) in Beaver typically lands around May 15, 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 5.
When is the first frost in Beaver?
The first hard freeze (28°F) in Beaver typically arrives around Sep 10, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Aug 27, so the watching starts about Aug 11 — about 118 days after the spring freeze cleared.
How long is the growing season in Beaver?
Measured between 28°F hard freezes, Beaver sees about 118 frost-free days — roughly May 15 through Sep 10, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 5 to Aug 27, about 83 days.
Is the soil safe to grow vegetables in Beaver?
No database can certify soil, but the federal record here is clean: we checked all 9 federal contamination source types and found no documented sites within the search radii around Beaver. That means nothing is on record — not that the land is certified clean — so a one-time soil test is still the way to know your own yard's history.
How do gardeners stretch the season in Beaver?
With about 118 frost-free days between hard freezes, Beaver 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 146 to 174 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the May 15 hard-freeze normal stretches the season without touching the calendar.
