Driggs, Idaho, sits in USDA hardiness zone 4b — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
Reliable performers under these conditions include cabbage, cranberry, cilantro, and collard greens; what your own ground favors still comes down to its soil, sun, and drainage.
Even in Driggs, 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 Driggs 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 Driggs
Each reading below is measured for Driggs itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredDriggs runs about 122 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
MeasuredDriggs 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.

The kind of country Driggs is in
Driggs sits in the Snake River Plain — EPA Level III, inside the wider North American Deserts. That is read at Driggs's own centroid rather than borrowed from Teton County.

Is it too late to plant in Driggs?
Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Apr 24; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 22 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Sep 21 — 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.

A note from Gnorman
What an experienced grower watches for around here
In and around Driggs, Nitrate runs higher than the national average — 114 sites within ~10 miles of Driggs. 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 Driggs
Everything above resolves to Driggs 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 Driggs
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 Driggs’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 Driggs
When does frost risk typically end in Driggs?
The last hard freeze (28°F) in Driggs typically lands around May 22, 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 12.
When is the first frost in Driggs?
The first hard freeze (28°F) in Driggs typically arrives around Sep 21, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 7, so the watching starts about Aug 22 — about 122 days after the spring freeze cleared.
How long is the growing season in Driggs?
Measured between 28°F hard freezes, Driggs sees about 122 frost-free days — roughly May 22 through Sep 21, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 12 to Sep 7, about 87 days.
Is the soil safe to grow vegetables in Driggs?
The federal record around Driggs shows 144 documented sites, mostly Nitrate entries (114), 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 Driggs?
With about 122 frost-free days between hard freezes, Driggs 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 150 to 178 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the May 22 hard-freeze normal stretches the season without touching the calendar.
