Mekoryuk, Alaska, sits in USDA hardiness zone 5a — room for a real mix of vegetables, fruit, and perennials matched to the local frost calendar.
The conditions favor cabbage, cranberry, lavender, and collard greens, among others — though every individual site edits that list with its own soil, sun, and drainage.
Even in Mekoryuk, 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 Mekoryuk 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 Mekoryuk
Each reading below is measured for Mekoryuk itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsMekoryuk runs about 142 days between hard freezes (read from Bethel Census Area, the closest normal to Mekoryuk) — 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
MeasuredMekoryuk sits in USDA hardiness zone 5a.
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 Mekoryuk?
Almost never — the real question is what to plant next. 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. 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 Mekoryuk
Everything above resolves to Mekoryuk as a whole — one PHZM band, read across 5K acres, with hard-freeze dates borrowed from Bethel 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 Mekoryuk
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 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 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 Mekoryuk
When does frost risk typically end in Mekoryuk?
The last hard freeze (28°F) in Mekoryuk 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 Mekoryuk?
The first hard freeze (28°F) in Mekoryuk 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 Mekoryuk?
Measured between 28°F hard freezes, Mekoryuk 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 Mekoryuk?
The federal record around Mekoryuk is light — 8 documented sites across the 9 federal source types we checked, mostly Nitrate entries (8), the nearest Nitrate record about 2.7 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 Mekoryuk?
With about 142 frost-free days between hard freezes, Mekoryuk 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.
Everything above is measured at Mekoryuk's scale — its 5a band and its 142-day season. Your yard writes its own version of Mekoryuk's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
