Heber-Overgaard, Arizona, sits in USDA hardiness zone 6b — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
Expect cabbage, blackberry, california poppy, and collard greens to be strong candidates here; the deciding factors on any one parcel stay local — soil, sun, and drainage.
Even in Heber-Overgaard, 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 Heber-Overgaard 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 Heber-Overgaard
Each reading below is measured for Heber-Overgaard itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredHeber-Overgaard runs about 152 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
MeasuredHeber-Overgaard sits in USDA hardiness zone 6b.
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 Heber-Overgaard is in
Heber-Overgaard sits in the Arizona/New Mexico Mountains — EPA Level III, inside the wider Temperate Sierras. That is read at Heber-Overgaard's own centroid, and it is not what its county reads: Navajo 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 Heber-Overgaard?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Apr 14; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 12 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 11 — 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.

Know Before You Grow
- •On a private well, test for nitrates: above 10 mg/L the water needs treatment before irrigating.
- •Underground tanks leak petroleum as they age — near a former filling station, test the soil.
- •PFAS do not break down in groundwater. Irrigate from a tested source.

Your land is one point inside Heber-Overgaard
Everything above resolves to Heber-Overgaard as a whole — one PHZM band and one 28°F frost record, read across 4K 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 Heber-Overgaard
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 Heber-Overgaard’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 Heber-Overgaard
When does frost risk typically end in Heber-Overgaard?
The last hard freeze (28°F) in Heber-Overgaard typically lands around May 12, 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 2.
When is the first frost in Heber-Overgaard?
The first hard freeze (28°F) in Heber-Overgaard typically arrives around Oct 11, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 27, so the watching starts about Sep 11 — about 152 days after the spring freeze cleared.
How long is the growing season in Heber-Overgaard?
Measured between 28°F hard freezes, Heber-Overgaard sees about 152 frost-free days — roughly May 12 through Oct 11, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 2 to Sep 27, about 117 days.
Is the soil safe to grow vegetables in Heber-Overgaard?
The federal record around Heber-Overgaard is light — 24 documented sites across the 9 federal source types we checked, mostly Nitrate entries (12), the nearest Underground Storage Tanks record about 0.5 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 I protect my plants from frost in Heber-Overgaard?
From about Sep 11 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 11 (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 11. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
