Bellemont, Arizona, sits in USDA hardiness zone 5b — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
Well-matched crops include cabbage, cranberry, lavender, and collard greens, and the gap between "grows in the area" and "grows in your yard" is closed by soil, sun, and drainage.
Even in Bellemont, 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 Bellemont 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 Bellemont
Each reading below is measured for Bellemont itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredBellemont runs about 122 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
MeasuredBellemont 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 Bellemont is in
Bellemont sits in the Arizona/New Mexico Mountains — EPA Level III, inside the wider Temperate Sierras. That is read at Bellemont's own centroid, and it is not what its county reads: Coconino County is mostly Arizona/New Mexico Plateau. The wider page above you is answering a different question about different ground.

Is it too late to plant in Bellemont?
Too late for some crops, right on time for others — a growing season is a sequence, not a deadline. 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 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.

What an experienced grower watches for around here
In and around Bellemont, Nitrate runs higher than the national average — 52 sites within ~10 miles of Bellemont. That's not a problem with your land — it's information about it.
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 Bellemont
Everything above resolves to Bellemont as a whole — one PHZM band and one 28°F frost record, read across 6K 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 Bellemont
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 Bellemont’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 Bellemont
When does frost risk typically end in Bellemont?
The last hard freeze (28°F) in Bellemont 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 Bellemont?
The first hard freeze (28°F) in Bellemont 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 122 days after the spring freeze cleared.
How long is the growing season in Bellemont?
Measured between 28°F hard freezes, Bellemont sees about 122 frost-free days — roughly May 28 through Sep 27, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 18 to Sep 13, about 87 days.
Is the soil safe to grow vegetables in Bellemont?
The federal record around Bellemont is a meaningful one — 177 documented sites, mostly Underground Storage Tanks entries (89), the nearest Underground Storage Tanks record about 0.5 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 gardeners stretch the season in Bellemont?
With about 122 frost-free days between hard freezes, Bellemont 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 150 to 178 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 Bellemont's scale — its 5b band and its 122-day season. Your yard writes its own version of Bellemont's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
