Unlikely — Zone Mismatch
one one (zones 10-12) does not overlap with New Mexico's zone range (5a-9a). Growing outdoors is unlikely without significant protection.
One zone short — what would close it
One One is hardy to zone 10, and the warmest ground in New Mexico is zone 9 — 1 zone short. Planted in open ground it will not survive a New Mexico winter. To grow it here, grow one one in a container and move it under cover for the coldest weeks, or give it a greenhouse.
Season extension and overwintering under cover both work at this margin. How to buy the weeks →

When to Plant One One in New Mexico
The frost window
Across New Mexico, the last spring hard freeze (28°F) clears between Mar 31 and Apr 19, and the first fall hard freeze lands between Oct 22 and Nov 9 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 186-day window you can count on — up to 223 days on a mild site in a kind year. That marks the hard freeze, not the last light frost, so tender transplants usually wait another 2-3 weeks.
Winter standing
New Mexico runs as cold as USDA zone 5, and no sourced winter-hardiness floor is on record for one one, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether one one is a permanent planting or a replant-every-spring crop for you turns on your own zone within New Mexico; check its hardiness range against that before treating it as long-lived ground.
Timing tuned to sub-state frost dates — Catron County, not the statewide average.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: USDA PLANTS Database. Your site's own frost dates can run earlier or later than the state range — a parcel report pins them down.
Growing Season Fit
The zone check says one one does not survive a New Mexico winter in the ground. The season figures below measure a different question — whether it could finish a season here at all — and they only bear on New Mexico under protection.
Frost-free days
One One wants 365+ frost-free days; a typical New Mexico site sees ~209 (NOAA Regional Climate Centers ACIS, 1991-2020) — 156 days short of what it needs. A typical New Mexico season does not carry this crop to harvest outdoors, and a gap that size is not one an earlier sowing date or a faster cultivar closes; growing it here means growing it under cover.
GDD and chill-hour figures are computed from PRISM 1991-2020 monthly climate normals; frost-free days from NOAA Regional Climate Centers ACIS, 1991-2020. Each is the state median across its counties (P25/P75 span the within-state spread). Hardiness-zone range is USDA PHZM 2023.
Soil + Drainage Fit
One One likes near-neutral soil (pH 5-7). That's the common-ground band across New Mexico's sandy loam and caliche — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 5.5 and 6.5 — worth knowing before you decide whether a New Mexico soil test result is a problem or just a number. Drainage requirement: poorly (saturated >50% of year). A soil-survey lookup (NRCS SSURGO) flags whether your specific site matches.
Your land, not the state average
New Mexico's soils run mostly loam, but SSURGO maps the series, texture, and drainage under your exact parcel. One One needs about 59 inches of workable depth, so it is that horizon — not the surface — you are testing for. That map unit, not the state average, decides how one one performs.

What Else to Consider for One One in New Mexico
Zone compatibility tells you about winter cold survival — but New Mexico growers also need to think about:
Very low rainfall requires irrigation for most crops
High altitude UV intensity can burn tender transplants
Alkaline soils limit plant selection without amendment
Growing one one here specifically
One One's deep root system wants open ground, yet a large share of New Mexico is SSURGO group-D soil — dense and slow-draining enough to stall it.
Double-dig or broadfork one one's bed to open the restrictive layer so roots can run. How to handle it →
What to actually do about these — and the constraints that apply to every New Mexico grower, not just one one — is covered on the New Mexico growing guide.
Timing shifts within New Mexico
New Mexico isn't one climate. In Catron County, the last hard freeze (28°F) holds until about May 22 — roughly 43 days later than the recorded state median — so plant one one to your county's window, not the statewide date.
One One needs about 365 days of frost-free season to complete its cycle. No New Mexico county gives it that outdoors: even Doña Ana County, the state’s longest season at 264 frost-free days, falls 101 days short — so it needs transplants, a short-season variety, or covered growing.
Across New Mexico’s 33 counties the frost-free season runs from 144 days in Catron County to 264 days in Doña Ana County — a spread of 120 days, which is why a single statewide planting date misleads. The median New Mexico county sees 209 frost-free days, which is 156 days short of what one one needs — so on a typical New Mexico parcel this is a transplant-or-protect crop, not a direct-sow one.
County last-freeze dates and frost-free day counts: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F freeze (earlier than the folk 32°F "last frost"). One One's 365-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.

Common Questions About Growing One One in New Mexico
When can I plant One One in New Mexico?
New Mexico's last spring hard freeze (28°F) clears between Mar 31 and Apr 19, and the first fall hard freeze lands between Oct 22 and Nov 9 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for One One, so this page does not state whether it overwinters in New Mexico and publishes no fall establishment date for it — check its hardiness range against your own zone before treating it as a permanent planting.
What hardiness zone is One One grown in across New Mexico?
New Mexico spans USDA hardiness zones 5a-9a (USDA ARS PHZM 2023). One One carries a range of zones 10-12, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical New Mexico site have?
A typical New Mexico site sees ~209 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). One One needs 365+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date. In cooler counties like Catron, the freeze-free season runs shorter than the state average, so verify your own county's window.
How should I amend the soil for One One in New Mexico?
One One prefers pH 5-7 and poorly (saturated >50% of year) drainage (FAO ECOCROP). That sits in the common-ground band across New Mexico soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
