Rio Lucio, 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 Rio Lucio, 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 Rio Lucio 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 Rio Lucio
Each reading below is measured for Rio Lucio itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredRio Lucio runs about 159 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
MeasuredRio Lucio 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 Rio Lucio is in
Rio Lucio sits in the Southern Rockies — EPA Level III, inside the wider Northwestern Forested Mountains. That is read at Rio Lucio's own centroid, and it is not what its county reads: Taos 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 Rio Lucio?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Apr 6; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 4 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 10 — 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.

What an experienced grower watches for around here
In and around Rio Lucio, Mining runs higher than the national average — 17 sites within ~10 miles of Rio Lucio. Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Mining: Mining sites — both historic and active — can leach heavy metals (arsenic, lead, cadmium, mercury) into soil and water for centuries after operations cease.
Test soil for heavy metals (lead, arsenic, cadmium, mercury) — this is essential near any mining site.

Your land is one point inside Rio Lucio
Everything above resolves to Rio Lucio as a whole — one PHZM band and one 28°F frost record, read across 673 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 Rio Lucio
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 Rio Lucio’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 Rio Lucio
When does frost risk typically end in Rio Lucio?
The last hard freeze (28°F) in Rio Lucio typically lands around May 4, 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 25.
When is the first frost in Rio Lucio?
The first hard freeze (28°F) in Rio Lucio typically arrives around Oct 10, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 26, so the watching starts about Sep 10 — about 159 days after the spring freeze cleared.
How long is the growing season in Rio Lucio?
Measured between 28°F hard freezes, Rio Lucio sees about 159 frost-free days — roughly May 4 through Oct 10, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 25 to Sep 26, about 124 days.
Is the soil safe to grow vegetables in Rio Lucio?
The federal record around Rio Lucio shows 50 documented sites, mostly Underground Storage Tanks entries (19), the nearest Underground Storage Tanks record about 0.3 miles out — a typical footprint for a growing area, and proximity to a documented site is information, not a diagnosis of any one yard. It's worth seeing which recorded sites sit closest to where you grow, and testing the soil before new food beds near any of them.
How do I protect my plants from frost in Rio Lucio?
From about Sep 10 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 10 (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 10. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
