Beaver Creek, Montana, sits in USDA hardiness zone 4a — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
These conditions suit cabbage, cranberry, turkish rocket, and collard greens — a starting list any specific site will trim or extend with its own soil, sun, and drainage.
Even in Beaver Creek, no two yards are alike.

What this means for growing in Beaver Creek
Each reading below is measured for Beaver Creek itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredBeaver Creek runs about 153 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.

Winter hardiness
MeasuredBeaver Creek sits in USDA hardiness zone 4a.
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 Beaver Creek is in
Beaver Creek sits in the Northwestern Glaciated Plains — EPA Level III, inside the wider Great Plains. That is read at Beaver Creek's own centroid rather than borrowed from Hill County.

Is it too late to plant in Beaver Creek?
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 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 2 — long-season crops need about 90 days of runway, quick greens only 30. Late in the year the fall bench takes over — quick greens, radishes, and garlic that repays you next summer.

What an experienced grower watches for around here
In and around Beaver Creek, Underground Storage Tanks runs higher than the national average — 98 sites within ~10 miles of Beaver Creek. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside Beaver Creek
Everything above resolves to Beaver Creek as a whole — one PHZM band and one 28°F frost record, read across 3K 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 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 Beaver Creek
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 Beaver Creek’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 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 Beaver Creek
When does frost risk typically end in Beaver Creek?
The last hard freeze (28°F) in Beaver Creek 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 Beaver Creek?
The first hard freeze (28°F) in Beaver Creek typically arrives around Oct 2, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 18, so the watching starts about Sep 2 — about 153 days after the spring freeze cleared.
How long is the growing season in Beaver Creek?
Measured between 28°F hard freezes, Beaver Creek sees about 153 frost-free days — roughly May 2 through Oct 2, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 23 to Sep 18, about 118 days.
Is the soil safe to grow vegetables in Beaver Creek?
The federal record around Beaver Creek shows 142 documented sites, mostly Underground Storage Tanks entries (98), the nearest Brownfields record about 0.6 miles 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 Beaver Creek?
From about Sep 2 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 2 (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 2. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
