Hoback, Wyoming, sits in USDA hardiness zone 5a — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
Crops well matched to these conditions include okra, cranberry, lavender, and pumpkin — though what thrives on any one site still turns on its specific soil, sun, and drainage.
Even in Hoback, 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 Hoback 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 Hoback
Each reading below is measured for Hoback itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredHoback runs about 119 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
MeasuredHoback sits in USDA hardiness zone 5a.
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 Hoback is in
Hoback sits in the Middle Rockies — EPA Level III, inside the wider Northwestern Forested Mountains. That is read at Hoback's own centroid rather than borrowed from Teton County.

Is it too late to plant in Hoback?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Apr 30; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 28 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Sep 24 — 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 Hoback, Nitrate runs higher than the national average — 24 sites within ~10 miles of Hoback. 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 Hoback
Everything above resolves to Hoback as a whole — one PHZM band and one 28°F frost record, read across 28K 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 Hoback
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 Hoback’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 Hoback
When does frost risk typically end in Hoback?
The last hard freeze (28°F) in Hoback typically lands around May 28, 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 18.
When is the first frost in Hoback?
The first hard freeze (28°F) in Hoback typically arrives around Sep 24, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 10, so the watching starts about Aug 25 — about 119 days after the spring freeze cleared.
How long is the growing season in Hoback?
Measured between 28°F hard freezes, Hoback sees about 119 frost-free days — roughly May 28 through Sep 24, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 18 to Sep 10, about 84 days.
Is the soil safe to grow vegetables in Hoback?
The federal record around Hoback shows 51 documented sites, mostly Nitrate entries (24), the nearest Nitrate record about 1.1 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 Hoback?
With about 119 frost-free days between hard freezes, Hoback 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 147 to 175 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the May 28 hard-freeze normal stretches the season without touching the calendar.
Everything above is measured at Hoback's scale — its 5a band and its 119-day season. Your yard writes its own version of Hoback's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
