Lonetree, Wyoming, sits in USDA hardiness zone 5b — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
Expect cabbage, cranberry, lavender, and collard greens to be strong candidates here; the deciding factors on any one parcel stay local — soil, sun, and drainage.
Even in Lonetree, 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 Lonetree 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 Lonetree
Each reading below is measured for Lonetree itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredLonetree runs about 127 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
MeasuredLonetree sits in USDA hardiness zone 5b.
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 Lonetree is in
Lonetree sits in the Wyoming Basin — EPA Level III, inside the wider North American Deserts. That is read at Lonetree's own centroid rather than borrowed from Uinta County.

Is it too late to plant in Lonetree?
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 25; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 23 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Sep 27 — 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.

Your land is one point inside Lonetree
Everything above resolves to Lonetree as a whole — one PHZM band and one 28°F frost record, read across 29K 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 Lonetree
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 Lonetree’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 Lonetree
When does frost risk typically end in Lonetree?
The last hard freeze (28°F) in Lonetree typically lands around May 23, 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 13.
When is the first frost in Lonetree?
The first hard freeze (28°F) in Lonetree typically arrives around Sep 27, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 13, so the watching starts about Aug 28 — about 127 days after the spring freeze cleared.
How long is the growing season in Lonetree?
Measured between 28°F hard freezes, Lonetree sees about 127 frost-free days — roughly May 23 through Sep 27, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 13 to Sep 13, about 92 days.
Is the soil safe to grow vegetables in Lonetree?
The federal record around Lonetree is light — 7 documented sites across the 9 federal source types we checked, mostly Nitrate entries (6), the nearest Nitrate record about 2.6 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 Lonetree?
With about 127 frost-free days between hard freezes, Lonetree 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 155 to 183 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the May 23 hard-freeze normal stretches the season without touching the calendar.
