Red Rock Ranch, New Mexico, sits in USDA hardiness zone 6a — a zone band wide enough that plant choice, not possibility, is the interesting question.
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 Red Rock Ranch, 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 Red Rock Ranch 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 Red Rock Ranch
Each reading below is measured for Red Rock Ranch itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredRed Rock Ranch runs about 160 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
MeasuredRed Rock Ranch 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 Red Rock Ranch is in

Is it too late to plant in Red Rock Ranch?
For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Apr 9; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 7 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 14 — long-season crops need about 90 days of runway, quick greens only 30. Even past midsummer there is room for a true fall garden here, and garlic planted near the close carries the momentum into next year.

What an experienced grower watches for around here
In and around Red Rock Ranch, two things run higher than the national average within ~10 miles of Red Rock Ranch — Superfund (12 sites) and Nitrate (90 sites). Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Superfund: Superfund sites represent the most severe contamination in the federal system.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
Commission professional soil testing before any food production (test for heavy metals, VOCs, and SVOCs).
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 Red Rock Ranch
Everything above resolves to Red Rock Ranch as a whole — one PHZM band and one 28°F frost record, read across 3K 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 Red Rock Ranch
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 Red Rock Ranch’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 Red Rock Ranch
When does frost risk typically end in Red Rock Ranch?
The last hard freeze (28°F) in Red Rock Ranch typically lands around May 7, 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 28.
When is the first frost in Red Rock Ranch?
The first hard freeze (28°F) in Red Rock Ranch typically arrives around Oct 14, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 30, so the watching starts about Sep 14 — about 160 days after the spring freeze cleared.
How long is the growing season in Red Rock Ranch?
Measured between 28°F hard freezes, Red Rock Ranch sees about 160 frost-free days — roughly May 7 through Oct 14, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 28 to Sep 30, about 125 days.
Is the soil safe to grow vegetables in Red Rock Ranch?
The federal record around Red Rock Ranch is a meaningful one — 117 documented sites, mostly Nitrate entries (90), the nearest Nitrate record about 0.4 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 Red Rock Ranch?
From about Sep 14 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 14 (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 14. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
