Pine Haven, Wyoming, sits in USDA hardiness zone 4b — room for a real mix of vegetables, fruit, and perennials matched to the local frost calendar.
Expect cabbage, cranberry, cilantro, and collard greens to be strong candidates here; the deciding factors on any one parcel stay local — soil, sun, and drainage.
Even in Pine Haven, 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 Pine Haven 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 Pine Haven
Each reading below is measured for Pine Haven itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredPine Haven 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
MeasuredPine Haven 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 Pine Haven is in
Pine Haven sits in the Middle Rockies — EPA Level III, inside the wider Northwestern Forested Mountains. That is read at Pine Haven's own centroid rather than borrowed from Crook County.

Is it too late to plant in Pine Haven?
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 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 3 — 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.

What an experienced grower watches for around here
In and around Pine Haven, Nitrate runs higher than the national average — 16 sites within ~10 miles of Pine Haven. 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 Pine Haven
Everything above resolves to Pine Haven as a whole — one PHZM band and one 28°F frost record, read across 843 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 Pine Haven
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 Pine Haven’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 Pine Haven
When does frost risk typically end in Pine Haven?
The last hard freeze (28°F) in Pine Haven 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 Pine Haven?
The first hard freeze (28°F) in Pine Haven typically arrives around Oct 3, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 19, so the watching starts about Sep 3 — about 149 days after the spring freeze cleared.
How long is the growing season in Pine Haven?
Measured between 28°F hard freezes, Pine Haven sees about 149 frost-free days — roughly May 7 through Oct 3, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 28 to Sep 19, about 114 days.
Is the soil safe to grow vegetables in Pine Haven?
The federal record around Pine Haven is light — 42 documented sites across the 9 federal source types we checked, mostly Underground Storage Tanks entries (24), the nearest Underground Storage Tanks record about 0.4 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 Pine Haven?
With about 149 frost-free days between hard freezes, Pine Haven 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 7 hard-freeze normal stretches the season without touching the calendar.
