Roosevelt, Minnesota, sits in USDA hardiness zone 3b — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
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 Roosevelt, 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 Roosevelt 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 Roosevelt
Each reading below is measured for Roosevelt itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredRoosevelt runs about 148 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
MeasuredRoosevelt 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.
USDA PHZM 2023
The kind of country Roosevelt is in
Roosevelt sits in the Northern Minnesota Wetlands — EPA Level III, inside the wider Northern Forests. That is read at Roosevelt's own centroid rather than borrowed from Roseau County.

Is it too late to plant in Roosevelt?
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 12; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 10 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 5 — long-season crops need about 90 days of runway, quick greens only 30. When the window is tight, the fall moves are quick ones — baby greens, radishes, and garlic set for next season.

- •Underground tanks leak petroleum as they age — near a former filling station, test the soil.
- •Near a brownfield, raised beds of imported soil give your food clean ground.
- •On a private well, test for nitrates: above 10 mg/L the water needs treatment before irrigating.

Your land is one point inside Roosevelt
Everything above resolves to Roosevelt as a whole — one PHZM band and one 28°F frost record, read across 657 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 Roosevelt
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 Roosevelt’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 Roosevelt
When does frost risk typically end in Roosevelt?
The last hard freeze (28°F) in Roosevelt typically lands around May 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 May 31.
When is the first frost in Roosevelt?
The first hard freeze (28°F) in Roosevelt typically arrives around Oct 5, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 21, so the watching starts about Sep 5 — about 148 days after the spring freeze cleared.
How long is the growing season in Roosevelt?
Measured between 28°F hard freezes, Roosevelt sees about 148 frost-free days — roughly May 10 through Oct 5, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 31 to Sep 21, about 113 days.
Is the soil safe to grow vegetables in Roosevelt?
The federal record around Roosevelt is light — 14 documented sites across the 9 federal source types we checked, mostly Underground Storage Tanks entries (9), the nearest Underground Storage Tanks 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 Roosevelt?
With about 148 frost-free days between hard freezes, Roosevelt 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 176 to 204 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the May 10 hard-freeze normal stretches the season without touching the calendar.
Everything above is measured at Roosevelt's scale — its 3b band and its 148-day season. Your yard writes its own version of Roosevelt's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
