Beulah, North Dakota, sits in USDA hardiness zone 4a — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
The conditions favor cabbage, cranberry, cilantro, and collard greens, among others — though every individual site edits that list with its own soil, sun, and drainage.
Even in Beulah, 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 Beulah 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 Beulah
Each reading below is measured for Beulah itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredBeulah runs about 149 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
MeasuredBeulah 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 Beulah is in
Beulah sits in the Northwestern Great Plains — EPA Level III, inside the wider Great Plains. That is read at Beulah's own centroid rather than borrowed from Mercer County.

Is it too late to plant in Beulah?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Apr 7; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 5 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 1 — 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.

A note from Gnorman
What an experienced grower watches for around here
In and around Beulah, Nitrate runs higher than the national average — 80 sites within ~10 miles of Beulah. Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
Test well water for nitrate if you rely on a private well for irrigation (EPA standard: 10 mg/L).

Your land is one point inside Beulah
Everything above resolves to Beulah as a whole — one PHZM band and one 28°F frost record, read across 2K 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 Beulah
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 Beulah’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 Beulah
When does frost risk typically end in Beulah?
The last hard freeze (28°F) in Beulah typically lands around May 5, 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 26.
When is the first frost in Beulah?
The first hard freeze (28°F) in Beulah typically arrives around Oct 1, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 17, so the watching starts about Sep 1 — about 149 days after the spring freeze cleared.
How long is the growing season in Beulah?
Measured between 28°F hard freezes, Beulah sees about 149 frost-free days — roughly May 5 through Oct 1, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 26 to Sep 17, about 114 days.
Is the soil safe to grow vegetables in Beulah?
The federal record around Beulah shows 127 documented sites, mostly Nitrate entries (80), the nearest Underground Storage Tanks record about 0.3 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 gardeners stretch the season in Beulah?
With about 149 frost-free days between hard freezes, Beulah 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 177 to 205 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the May 5 hard-freeze normal stretches the season without touching the calendar.
Everything above is measured at Beulah's scale — its 4a band and its 149-day season. Your yard writes its own version of Beulah's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
