Scranton, North Dakota, sits in USDA hardiness zone 4b — room for a real mix of vegetables, fruit, and perennials matched to the local frost calendar.
A short list that earns its place here — cabbage, cranberry, cilantro, and collard greens — with any one site's soil, sun, and drainage making the final cut.
Even in Scranton, 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 Scranton 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 Scranton
Each reading below is measured for Scranton itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredScranton 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
MeasuredScranton sits in USDA hardiness zone 4b.
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 Scranton is in
Scranton sits in the Northwestern Great Plains — EPA Level III, inside the wider Great Plains. That is read at Scranton's own centroid rather than borrowed from Bowman County.

Is it too late to plant in Scranton?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Apr 9; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 7 (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. In a season this compact, fast finishers and cold-hardy greens do the late work, and garlic tucked in before the freeze repays you next summer.

What an experienced grower watches for around here
In and around Scranton, Nitrate runs higher than the national average — 204 sites within ~10 miles of Scranton. That's not a problem with your land — it's information about it.
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 Scranton
Everything above resolves to Scranton as a whole — one PHZM band and one 28°F frost record, read across 439 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 Scranton
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 Scranton’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 Scranton
When does frost risk typically end in Scranton?
The last hard freeze (28°F) in Scranton typically lands around May 7, 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 28.
When is the first frost in Scranton?
The first hard freeze (28°F) in Scranton 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 148 days after the spring freeze cleared.
How long is the growing season in Scranton?
Measured between 28°F hard freezes, Scranton sees about 148 frost-free days — roughly May 7 through Oct 2, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 28 to Sep 18, about 113 days.
Is the soil safe to grow vegetables in Scranton?
The federal record around Scranton is a meaningful one — 212 documented sites, mostly Nitrate entries (204), the nearest Underground Storage Tanks record about 0.1 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 Scranton?
With about 148 frost-free days between hard freezes, Scranton 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 7 hard-freeze normal stretches the season without touching the calendar.
Everything above is measured at Scranton's scale — its 4b band and its 148-day season. Your yard writes its own version of Scranton's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
