Prescott Valley, Arizona, sits in USDA hardiness zone 7b — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
These conditions suit cabbage, prickly pear, california poppy, and collard greens — a starting list any specific site will trim or extend with its own soil, sun, and drainage.

What this means for growing in Prescott Valley
Each reading below is measured for Prescott Valley itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredPrescott Valley runs about 217 days between hard freezes — a long growing season.
There is slack for succession plantings and slow-finishing crops: many vegetables can be sown twice, and the heat-lovers have time to ripen fully.
Plan a second sowing of quick crops after the first comes out, and use the fall window most gardeners let sit idle.
NOAA 1991–2020 Climate Normals
Winter hardiness
MeasuredPrescott Valley sits in USDA hardiness zone 7b.
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 Prescott Valley is in
Prescott Valley sits in the Arizona/New Mexico Plateau — EPA Level III, inside the wider North American Deserts. That is read at Prescott Valley's own centroid, and it is not what its county reads: Yavapai County is mostly Arizona/New Mexico Mountains. The wider page above you is answering a different question about different ground.

Is it too late to plant in Prescott Valley?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Mar 6; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 3 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 6 — long-season crops need about 90 days of runway, quick greens only 30. There is slack in a calendar like this — late plantings, second rounds of favorites, and a fall bench that keeps beds working.

What an experienced grower watches for around here
In and around Prescott Valley, two things run higher than the national average within ~10 miles of Prescott Valley — Mining (97 sites) and Superfund (6 sites). That's not a problem with your land — it's information about 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.
Superfund: Superfund sites represent the most severe contamination in the federal system.
Test soil for heavy metals (lead, arsenic, cadmium, mercury) — this is essential near any mining site.
Commission professional soil testing before any food production (test for heavy metals, VOCs, and SVOCs).

Your land is one point inside Prescott Valley
Everything above resolves to Prescott Valley as a whole — one PHZM band and one 28°F frost record, read across 26K 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 Prescott Valley
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 Prescott Valley’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 Prescott Valley
When does frost risk typically end in Prescott Valley?
The last hard freeze (28°F) in Prescott Valley typically lands around Apr 3, 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 Apr 24.
When is the first frost in Prescott Valley?
The first hard freeze (28°F) in Prescott Valley typically arrives around Nov 6, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Oct 23, so the watching starts about Oct 7 — about 217 days after the spring freeze cleared.
How long is the growing season in Prescott Valley?
Measured between 28°F hard freezes, Prescott Valley sees about 217 frost-free days — roughly Apr 3 through Nov 6, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 24 to Oct 23, about 182 days.
Is the soil safe to grow vegetables in Prescott Valley?
The federal record around Prescott Valley runs heavier than most — 418 documented sites, mostly Underground Storage Tanks entries (159), the nearest Underground Storage Tanks record about 0.2 miles out — so test the soil before planting food in the ground, and raised beds with clean imported soil grow well in the meantime. Even here, proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what's recorded and where.
How do I protect my plants from frost in Prescott Valley?
From about Oct 7 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 Nov 6 (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 Nov 6. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
Everything above is measured at Prescott Valley's scale — its 7b band and its 217-day season. Your yard writes its own version of Prescott Valley's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
