Emigrant, Montana, sits in USDA hardiness zone 5a — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
These conditions suit cabbage, cranberry, lavender, and collard greens — a starting list any specific site will trim or extend with its own soil, sun, and drainage.
Even in Emigrant, no two yards are alike.

What this means for growing in Emigrant
Each reading below is measured for Emigrant itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredEmigrant runs about 147 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
MeasuredEmigrant sits in USDA hardiness zone 5a.
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 Emigrant is in
Emigrant sits in the Middle Rockies — EPA Level III, inside the wider Northwestern Forested Mountains. That is read at Emigrant's own centroid rather than borrowed from Park County.

Is it too late to plant in Emigrant?
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 11; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 9 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 3 — 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.

What an experienced grower watches for around here
In and around Emigrant, Mining runs higher than the national average — 30 sites within ~10 miles of Emigrant. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around 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.
Test soil for heavy metals (lead, arsenic, cadmium, mercury) — this is essential near any mining site.

Your land is one point inside Emigrant
Everything above resolves to Emigrant as a whole — one PHZM band and one 28°F frost record, read across 7K 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 Emigrant
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 Emigrant’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 Emigrant
When does frost risk typically end in Emigrant?
The last hard freeze (28°F) in Emigrant typically lands around May 9, 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 30.
When is the first frost in Emigrant?
The first hard freeze (28°F) in Emigrant typically arrives around Oct 3, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 19, so the watching starts about Sep 3 — about 147 days after the spring freeze cleared.
How long is the growing season in Emigrant?
Measured between 28°F hard freezes, Emigrant sees about 147 frost-free days — roughly May 9 through Oct 3, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 30 to Sep 19, about 112 days.
Is the soil safe to grow vegetables in Emigrant?
The federal record around Emigrant is a meaningful one — 44 documented sites, mostly Mining entries (30), the nearest Underground Storage Tanks record about 0.6 miles out — so a soil test before new food beds is a sensible precaution here, not a reason to hold back from growing. Remember that proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what sits where.
How do gardeners stretch the season in Emigrant?
With about 147 frost-free days between hard freezes, Emigrant 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 175 to 203 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the May 9 hard-freeze normal stretches the season without touching the calendar.
Everything above is measured at Emigrant's scale — its 5a band and its 147-day season. Your yard writes its own version of Emigrant's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
