Aberdeen, Idaho, sits in USDA hardiness zone 5b — a zone band wide enough that plant choice, not possibility, is the interesting question.
A short list that earns its place here — cabbage, cranberry, lavender, and collard greens — with any one site's soil, sun, and drainage making the final cut.
Even in Aberdeen, 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 Aberdeen 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 Aberdeen
Each reading below is measured for Aberdeen itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredAberdeen runs about 155 days between hard freezes — a moderate growing season.
There is room for the full run of cool-season crops plus a warm-season main crop, but the calendar is tight enough that a late spring or early fall frost still decides how much finishes.
Time warm-season transplants to your last hard freeze, and a few weeks of season extension turns a near-miss harvest into a sure one.
NOAA 1991–2020 Climate Normals
Winter hardiness
MeasuredAberdeen sits in USDA hardiness zone 5b.
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.

The kind of country Aberdeen is in
Aberdeen sits in the Snake River Plain — EPA Level III, inside the wider North American Deserts. That is read at Aberdeen's own centroid rather than borrowed from Bingham County.

Is it too late to plant in Aberdeen?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Apr 4; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 2 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 4 — long-season crops need about 90 days of runway, quick greens only 30. As the window narrows, the plantings just get faster — fall brassicas, then greens, then garlic to finish.

A note from Gnorman
What an experienced grower watches for around here
In and around Aberdeen, Nitrate runs higher than the national average — 70 sites within ~10 miles of Aberdeen. Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
Test well water for nitrate if you rely on a private well for irrigation (EPA standard: 10 mg/L).

Your land is one point inside Aberdeen
Everything above resolves to Aberdeen as a whole — one PHZM band and one 28°F frost record, read across 659 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 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 Aberdeen
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 Aberdeen’s own record; 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 Aberdeen
When does frost risk typically end in Aberdeen?
The last hard freeze (28°F) in Aberdeen typically lands around May 2, 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 23.
When is the first frost in Aberdeen?
The first hard freeze (28°F) in Aberdeen typically arrives around Oct 4, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 20, so the watching starts about Sep 4 — about 155 days after the spring freeze cleared.
How long is the growing season in Aberdeen?
Measured between 28°F hard freezes, Aberdeen sees about 155 frost-free days — roughly May 2 through Oct 4, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 23 to Sep 20, about 120 days.
Is the soil safe to grow vegetables in Aberdeen?
The federal record around Aberdeen shows 115 documented sites, mostly Nitrate entries (70), the nearest Underground Storage Tanks record under a tenth of a mile out — a typical footprint for a growing area, and proximity to a documented site is information, not a diagnosis of any one yard. It's worth seeing which recorded sites sit closest to where you grow, and testing the soil before new food beds near any of them.
How do I protect my plants from frost in Aberdeen?
From about Sep 4 the job here turns from planting to protecting — the last start even a 30-day crop can finish. As the season closes around the first 28°F hard freeze near Oct 4 (NOAA 1991–2020 climate normals), three moves buy time: row cover or an old sheet over tender plants on still, clear nights; water the soil the afternoon before a freeze, so it holds warmth overnight; and harvest tomatoes, peppers and basil before Oct 4. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
Everything above is measured at Aberdeen's scale — its 5b band and its 155-day season. Your yard writes its own version of Aberdeen's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
