Nome Census Area, in Alaska, sits in USDA hardiness zones 3a-4b — a zone band wide enough that plant choice, not possibility, is the interesting question.
The conditions favor cabbage, cranberry, epazote, and collard greens, among others — though every individual site edits that list with its own soil, sun, and drainage.

Every figure names the dataset it came from. Hard-freeze dates are county 28°F normals: light frosts run a few weeks past them, and tender transplants usually wait 2–3 weeks after the last hard freeze.

Soil in Nome County
Across Nome County, the ground is predominantly Gelisols, where Nikaat, Sikinik, and Apun are the most extensive named soil series. The soil is generally very poorly drained with a mucky silt loam surface. Topsoil pH runs about 4.8–5.6, strongly acidic. Rainfall drains through hydrologic group B/D soils.

How the ground varies across Nome Census Area
The USDA soil survey maps 41% of Nome Census Area as very poorly drained — but another 42% drains differently: 21% well drained, 16% poorly drained.
Nikaat is the most extensive named soil at 3% of mapped acres, then Sikinik (2%) and Apun (2%).
Which of them your own lot sits on is a parcel question, not a county one. Check your address for the survey at your boundary.
What this means for growing in Nome Census Area
Each reading below is measured for Nome Census Area itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Drainage
MeasuredThe dominant soils across Nome Census Area are very poorly drained, in hydrologic group B/D — ground that sheds water slowly.
Beds can stay saturated for days after heavy rain, and the roots of most vegetables, berries, and fruit trees suffocate or rot in soil that never drains.
Raised beds or mounded rows lift roots above the wet zone; choose water-tolerant crops for the lowest spots.
USDA NRCS SSURGO
Surface pH
MeasuredTopsoil across Nome Census Area runs about pH 4.8–5.6, on the acidic side.
Blueberries, potatoes, and rhododendrons thrive in it, but most vegetables start locking out nutrients below about pH 6.0 and grow pale and stunted no matter how much you feed them.
A measured lime application raises pH for the crops that need it — but test first, because the right rate depends on your own soil, not the county average.
USDA NRCS SSURGO
Season length
MeasuredNome Census Area runs about 118 days between hard freezes — 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
MeasuredNome Census Area sits in USDA hardiness zones 3a-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.

What Grows in Nome Census Area
We scored all 1,086 plants against Nome Census Area's own USDA zone 3a-4b and its own 118-day season between hard freezes, using the same matching engine that runs a full parcel report. These cleared both. Sun, soil pH and drainage vary lot by lot — those are the parcel questions below. Each card opens that plant's Alaska profile.
Is it too late to plant in Nome Census Area?
Too late for some crops, right on time for others — a growing season is a sequence, not a deadline. 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 19 — 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.
Safe to Grow Here?
What the federal record shows across Nome County — and how to grow with it.
We checked the federal record across Nome County — 525 documented sites across 6 of the 9 source types we track.
The most significant on record: 13 Superfund sites (none NPL-listed). Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Nome Census Area carries one of the heavier federal records we track — and that's not a verdict on your yard. Proximity to a documented site is information, not a diagnosis: nothing here says any particular parcel is affected. It does earn one concrete step — before food beds go in the ground, a professional soil test tells you exactly what you're working with, and raised beds with clean imported soil grow well almost anywhere in the meantime.
Sources: EPA, USGS — 1.8M documented sites tracked nationwide across 9 federal source types.

What an experienced grower watches for around here
In and around Nome Census Area, two things run higher than the national average across Nome County — Mining (449 sites) and Superfund (13 sites). That's not a problem with your land — it's information about it.
Mining: Mining sites — both historic and active — can leach heavy metals (arsenic, lead, cadmium, mercury) into soil and water for centuries after operations cease.
Superfund: Superfund sites represent the most severe contamination in the federal system.
Test soil for heavy metals (lead, arsenic, cadmium, mercury) — this is essential near any mining site.
Commission professional soil testing before any food production (test for heavy metals, VOCs, and SVOCs).

Your land is one point inside Nome Census Area
Everything above resolves to Nome Census Area as a whole — one PHZM band and one county frost record, read across 14.7M acres. 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 county 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 county average.

How we know this about Nome Census Area
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at county grain; hard-freeze dates from NOAA 1991–2020 28°F normals at this county’s own record where one resolves, and the labelled statewide window where none does; soils from the USDA NRCS SSURGO survey, area-weighted across the county’s own map units; boundaries and acreage from US Census TIGER/Line 2025; the contamination and pesticide records from the federal sources named in their beats above. Where Nome Census Area carries no record of its own, the figure is inherited and labelled — the resolution ledger below names each.
Common questions about Nome Census Area
When does frost risk typically end in Nome Census Area?
The last hard freeze (28°F) in Nome Census Area 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.
How long is the growing season in Nome Census Area?
Measured between 28°F hard freezes, Nome Census Area sees about 118 frost-free days — roughly May 24 through Sep 19, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 14 to Sep 5, about 83 days.
Is the soil safe to grow vegetables in Nome Census Area?
The federal record around Nome Census Area runs heavier than most — 525 documented sites, mostly Mining entries (449), the nearest Mining record about 2.0 miles out — so test the soil before planting food in the ground, and raised beds with clean imported soil grow well in the meantime. Even here, proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what's recorded and where.
How do gardeners stretch the season in Nome Census Area?
With about 118 frost-free days between hard freezes, Nome Census Area 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 24 hard-freeze normal stretches the season without touching the calendar.
Everything above is measured at Nome Census Area's scale — its 3a-4b band and its 118-day season. Your yard writes its own version of Nome Census Area's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
