Pinedale, Wyoming, sits in USDA hardiness zone 4a — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
Well-matched crops include zucchini, cranberry, cilantro, and okra, and the gap between "grows in the area" and "grows in your yard" is closed by soil, sun, and drainage.
Even in Pinedale, 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 Pinedale 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 Pinedale
Each reading below is measured for Pinedale itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredPinedale runs about 83 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
MeasuredPinedale 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 Pinedale is in
Pinedale sits in the Wyoming Basin — EPA Level III, inside the wider North American Deserts. That is read at Pinedale's own centroid rather than borrowed from Sublette County.

Is it too late to plant in Pinedale?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around May 12; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Jun 9 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Aug 31 — long-season crops need about 90 days of runway, quick greens only 30. Even here the calendar’s edges hold value: thirty-day greens late in the window, then garlic and a rested bed for spring.

A note from Gnorman
What an experienced grower watches for around here
In and around Pinedale, Nitrate runs higher than the national average — 20 sites within ~10 miles of Pinedale. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around 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 Pinedale
Everything above resolves to Pinedale as a whole — one PHZM band and one 28°F frost record, read across 1K 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 Pinedale
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 Pinedale’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 Pinedale
When does frost risk typically end in Pinedale?
The last hard freeze (28°F) in Pinedale typically lands around Jun 9, 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 30.
When is the first frost in Pinedale?
The first hard freeze (28°F) in Pinedale typically arrives around Aug 31, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Aug 17, so the watching starts about Aug 1 — about 83 days after the spring freeze cleared.
How long is the growing season in Pinedale?
Measured between 28°F hard freezes, Pinedale sees about 83 frost-free days — roughly Jun 9 through Aug 31, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 30 to Aug 17, about 48 days.
Is the soil safe to grow vegetables in Pinedale?
The federal record around Pinedale shows 55 documented sites, mostly Underground Storage Tanks entries (25), the nearest Underground Storage Tanks record under a tenth of a mile 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 Pinedale?
With about 83 frost-free days between hard freezes, Pinedale 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 111 to 139 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the Jun 9 hard-freeze normal stretches the season without touching the calendar.
Everything above is measured at Pinedale's scale — its 4a band and its 83-day season. Your yard writes its own version of Pinedale's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
