Aleknagik, Alaska, sits in USDA hardiness zone 4b — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
The conditions favor cabbage, cranberry, cilantro, and collard greens, among others — though every individual site edits that list with its own soil, sun, and drainage.
Even in Aleknagik, 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 Aleknagik 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 Aleknagik
Each reading below is measured for Aleknagik itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsAleknagik runs about 135 days between hard freezes (read from Dillingham Census Area, the closest normal to Aleknagik) — 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
MeasuredAleknagik sits in USDA hardiness zone 4b.
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 Aleknagik?
For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Apr 15; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 13 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Sep 25 — 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.

Your land is one point inside Aleknagik
Everything above resolves to Aleknagik as a whole — one PHZM band, read across 17K acres, with hard-freeze dates borrowed from Dillingham Census Area’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 Aleknagik
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 Dillingham 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 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 Aleknagik
When does frost risk typically end in Aleknagik?
The last hard freeze (28°F) in Aleknagik typically lands around May 13, 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 3.
When is the first frost in Aleknagik?
The first hard freeze (28°F) in Aleknagik typically arrives around Sep 25, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 11, so the watching starts about Aug 26 — about 135 days after the spring freeze cleared.
How long is the growing season in Aleknagik?
Measured between 28°F hard freezes, Aleknagik sees about 135 frost-free days — roughly May 13 through Sep 25, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 3 to Sep 11, about 100 days.
Is the soil safe to grow vegetables in Aleknagik?
The federal record around Aleknagik is a meaningful one — 6 documented sites, mostly Mining entries (4), the nearest Mining record about 1.5 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 Aleknagik?
With about 135 frost-free days between hard freezes, Aleknagik 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 163 to 191 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the May 13 hard-freeze normal stretches the season without touching the calendar.
