Loring Colony, Montana, sits in USDA hardiness zone 3b — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
Growers here do well with cabbage, cranberry, epazote, and collard greens — with the usual caveat that any single yard's soil, sun, and drainage cast the deciding vote.
Even in Loring Colony, 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 Loring Colony 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 Loring Colony
Each reading below is measured for Loring Colony itself — here is what it means for a garden here, and the move an experienced grower makes about it.

Season length
MeasuredLoring Colony runs about 137 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.

Winter hardiness
MeasuredLoring Colony sits in USDA hardiness zone 3b.
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 Loring Colony is in
Loring Colony sits in the Northwestern Glaciated Plains — EPA Level III, inside the wider Great Plains. That is read at Loring Colony's own centroid rather than borrowed from Phillips County.

Is it too late to plant in Loring Colony?
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 16; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 14 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Sep 28 — 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.

Know Before You Grow
- •On a private well, test for nitrates: above 10 mg/L the water needs treatment before irrigating.
- •Underground tanks leak petroleum as they age — near a former filling station, test the soil.
- •Large animal operations push nitrates and bacteria downstream. Below one, test your water.

Your land is one point inside Loring Colony
Everything above resolves to Loring Colony as a whole — one PHZM band and one 28°F frost record, read across 237 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 Loring Colony
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 Loring Colony’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 Loring Colony
When does frost risk typically end in Loring Colony?
The last hard freeze (28°F) in Loring Colony typically lands around May 14, 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 4.
When is the first frost in Loring Colony?
The first hard freeze (28°F) in Loring Colony typically arrives around Sep 28, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 14, so the watching starts about Aug 29 — about 137 days after the spring freeze cleared.
How long is the growing season in Loring Colony?
Measured between 28°F hard freezes, Loring Colony sees about 137 frost-free days — roughly May 14 through Sep 28, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 4 to Sep 14, about 102 days.
Is the soil safe to grow vegetables in Loring Colony?
The federal record around Loring Colony is light — 11 documented sites across the 9 federal source types we checked, mostly Nitrate entries (8), the nearest CAFO record about 0.3 miles out — and proximity to a documented site is information, not a diagnosis of any one yard. Growing food here starts from a strong position; a soil test before new food beds settles any site-specific question.
How do gardeners stretch the season in Loring Colony?
With about 137 frost-free days between hard freezes, Loring Colony 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 165 to 193 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the May 14 hard-freeze normal stretches the season without touching the calendar.
Everything above is measured at Loring Colony's scale — its 3b band and its 137-day season. Your yard writes its own version of Loring Colony's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
