Peter, Utah, sits in USDA hardiness zone 6a — room for a real mix of vegetables, fruit, and perennials matched to the local frost calendar.
A short list that earns its place here — cabbage, blackberry, california poppy, and collard greens — with any one site's soil, sun, and drainage making the final cut.
Even in Peter, 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 Peter 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 Peter
Each reading below is measured for Peter itself — here is what it means for a garden here, and the move an experienced grower makes about it.

Season length
MeasuredPeter runs about 174 days between hard freezes — a moderate growing season.
There is room for the full run of cool-season crops plus a warm-season main crop, but the calendar is tight enough that a late spring or early fall frost still decides how much finishes.
Time warm-season transplants to your last hard freeze, and a few weeks of season extension turns a near-miss harvest into a sure one.

Winter hardiness
MeasuredPeter sits in USDA hardiness zone 6a.
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 Peter is in
Peter sits in the Central Basin and Range — EPA Level III, inside the wider North American Deserts. That is read at Peter's own centroid, and it is not what its county reads: Cache County is mostly Wasatch and Uinta Mountains. The wider page above you is answering a different question about different ground.

Is it too late to plant in Peter?
For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Mar 27; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 24 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 15 — long-season crops need about 90 days of runway, quick greens only 30. As the window narrows, the plantings just get faster — fall brassicas, then greens, then garlic to finish.

A note from Gnorman
What an experienced grower watches for around here
In and around Peter, two things run higher than the national average within ~10 miles of Peter — CAFO (13 sites) and Toxics Release Inventory (33 sites). Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
CAFO: CAFOs pose a different contamination profile than chemical sources.
Toxics Release Inventory: TRI facilities report annual chemical releases to air, water, and land.
Wash all produce consumed raw thoroughly, especially leafy greens grown near CAFOs.
Check prevailing wind direction — downwind parcels face higher exposure than upwind or crosswind locations.

Your land is one point inside Peter
Everything above resolves to Peter as a whole — one PHZM band and one 28°F frost record, read across 14K 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 Peter
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 Peter’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 Peter
When does frost risk typically end in Peter?
The last hard freeze (28°F) in Peter typically lands around Apr 24, 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 15.
When is the first frost in Peter?
The first hard freeze (28°F) in Peter typically arrives around Oct 15, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Oct 1, so the watching starts about Sep 15 — about 174 days after the spring freeze cleared.
How long is the growing season in Peter?
Measured between 28°F hard freezes, Peter sees about 174 frost-free days — roughly Apr 24 through Oct 15, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 15 to Oct 1, about 139 days.
Is the soil safe to grow vegetables in Peter?
The federal record around Peter is a meaningful one — 407 documented sites, mostly Underground Storage Tanks entries (186), the nearest Nitrate record about 1.3 miles out — so a soil test before new food beds is a sensible precaution here, not a reason to hold back from growing. Remember that proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what sits where.
How do I protect my plants from frost in Peter?
From about Sep 15 the job here turns from planting to protecting — the last start even a 30-day crop can finish. As the season closes around the first 28°F hard freeze near Oct 15 (NOAA 1991–2020 climate normals), three moves buy time: row cover or an old sheet over tender plants on still, clear nights; water the soil the afternoon before a freeze, so it holds warmth overnight; and harvest tomatoes, peppers and basil before Oct 15. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
Everything above is measured at Peter's scale — its 6a band and its 174-day season. Your yard writes its own version of Peter's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
