Levelock, Alaska, sits in USDA hardiness zone 4b — room for a real mix of vegetables, fruit, and perennials matched to the local frost calendar.
On paper, cabbage, cranberry, cilantro, and collard greens all suit these conditions — on the ground, soil, sun, and drainage make the final call.
Even in Levelock, 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 Levelock 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 Levelock
Each reading below is measured for Levelock itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsLevelock runs about 135 days between hard freezes (read from Lake and Peninsula Borough, the closest normal to Levelock) — 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
MeasuredLevelock 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 Levelock?
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. 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 Levelock
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 Levelock
Everything above resolves to Levelock as a whole — one PHZM band, read across 11K acres, with hard-freeze dates borrowed from Lake and Peninsula 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 Levelock
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 Lake and Peninsula 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 Levelock
When does frost risk typically end in Levelock?
The last hard freeze (28°F) in Levelock 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 Levelock?
The first hard freeze (28°F) in Levelock 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 Levelock?
Measured between 28°F hard freezes, Levelock 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 Levelock?
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 Levelock. 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 Levelock?
With about 135 frost-free days between hard freezes, Levelock 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.
Everything above is measured at Levelock's scale — its 4b band and its 135-day season. Your yard writes its own version of Levelock's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
