Fox Park, Wyoming, sits in USDA hardiness zone 4b — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
Among the crops suited to this profile: pumpkin, cranberry, st. johns wort, and zucchini. The site-level story — soil, sun, drainage — decides the rest.
Even in Fox Park, 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 Fox Park 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 Fox Park
Each reading below is measured for Fox Park itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredFox Park runs about 46 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
MeasuredFox Park 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 Fox Park is in
Fox Park sits in the Southern Rockies — EPA Level III, inside the wider Northwestern Forested Mountains. That is read at Fox Park's own centroid, and it is not what its county reads: Albany County is mostly Wyoming Basin. The wider page above you is answering a different question about different ground.

Is it too late to plant in Fox Park?
Almost never — the real question is what to plant next. Cool-season crops can go in from around May 25; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Jun 22 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Aug 7 — long-season crops need about 90 days of runway, quick greens only 30. When the window is tight, the fall moves are quick ones — baby greens, radishes, and garlic set for next season.

A note from Gnorman
What an experienced grower watches for around here
In and around Fox Park, Mining runs higher than the national average — 26 sites within ~10 miles of Fox Park. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
Mining: Mining sites — both historic and active — can leach heavy metals (arsenic, lead, cadmium, mercury) into soil and water for centuries after operations cease.
Test soil for heavy metals (lead, arsenic, cadmium, mercury) — this is essential near any mining site.

Your land is one point inside Fox Park
Everything above resolves to Fox Park as a whole — one PHZM band and one 28°F frost record, read across 635 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 Fox Park
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 Fox Park’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 Fox Park
When does frost risk typically end in Fox Park?
The last hard freeze (28°F) in Fox Park typically lands around Jun 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 Jul 13.
When is the first frost in Fox Park?
The first hard freeze (28°F) in Fox Park typically arrives around Aug 7, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Jul 24, so the watching starts about Jul 8 — about 46 days after the spring freeze cleared.
How long is the growing season in Fox Park?
Measured between 28°F hard freezes, Fox Park sees about 46 frost-free days — roughly Jun 22 through Aug 7, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jul 13 to Jul 24, about 11 days.
Is the soil safe to grow vegetables in Fox Park?
The federal record around Fox Park shows 40 documented sites, mostly Mining entries (26), 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 Fox Park?
With about 46 frost-free days between hard freezes, Fox Park 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 74 to 102 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the Jun 22 hard-freeze normal stretches the season without touching the calendar.
