Halsey, Oregon, sits in USDA hardiness zone 8b — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
A short list that earns its place here — cabbage, fig, california poppy, and collard greens — with any one site's soil, sun, and drainage making the final cut.
Even in Halsey, 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 Halsey 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 Halsey
Each reading below is measured for Halsey itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsHalsey runs about 258 days between hard freezes (read from Linn County, the closest normal to Halsey) — a long growing season.
There is slack for succession plantings and slow-finishing crops: many vegetables can be sown twice, and the heat-lovers have time to ripen fully.
Plan a second sowing of quick crops after the first comes out, and use the fall window most gardeners let sit idle.

Winter hardiness
MeasuredHalsey sits in USDA hardiness zone 8b.
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 Halsey is in
Halsey sits in the Willamette Valley — EPA Level III, inside the wider Marine West Coast Forest. That is read at Halsey's own centroid, and it is not what its county reads: Linn County is mostly Cascades. The wider page above you is answering a different question about different ground.

Is it too late to plant in Halsey?
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 Feb 10; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 10 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 23 — long-season crops need about 90 days of runway, quick greens only 30. With a season this long, “too late” mostly means “switch crops” — second sowings and a full fall garden are the norm, with garlic closing the year.

What an experienced grower watches for around here
In and around Halsey, Toxics Release Inventory runs higher than the national average — 12 sites within ~10 miles of Halsey. Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Toxics Release Inventory: TRI facilities report annual chemical releases to air, water, and land.

Your land is one point inside Halsey
Everything above resolves to Halsey as a whole — one PHZM band, read across 362 acres, with hard-freeze dates borrowed from Linn County’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 Halsey
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 Linn County’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 Halsey
When does frost risk typically end in Halsey?
The last hard freeze (28°F) in Halsey typically lands around Mar 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 Mar 31.
When is the first frost in Halsey?
The first hard freeze (28°F) in Halsey typically arrives around Nov 23, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 9, so the watching starts about Oct 24 — about 258 days after the spring freeze cleared.
How long is the growing season in Halsey?
Measured between 28°F hard freezes, Halsey sees about 258 frost-free days — roughly Mar 10 through Nov 23, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 31 to Nov 9, about 223 days.
Is the soil safe to grow vegetables in Halsey?
The federal record around Halsey shows 102 documented sites, mostly Underground Storage Tanks entries (61), 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 Halsey?
From about Oct 24 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 Nov 23 (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 Nov 23. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
Everything above is measured at Halsey's scale — its 8b band and its 258-day season. Your yard writes its own version of Halsey's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
