Roosevelt County, in New Mexico, sits in USDA hardiness zone 7b — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
On paper, green chile, pecan, pinon pine, and prickly pear all suit these conditions — on the ground, soil, sun, and drainage make the final call.
Roosevelt County lies within the High Plains — a regional growing area with its own character.

Is it too late to plant in Roosevelt County?
For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Feb 9; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 9 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 17 — long-season crops need about 90 days of runway, quick greens only 30. A long window like this one runs successions deep into fall — and even its last weeks take quick greens and garlic.

Growing Challenges in New Mexico
What an experienced grower plans around here — each one has a move.

Very low rainfall requires irrigation for most crops
High-desert growing starts with the water plan — drip lines, deep mulch, and basins put scarce rain exactly where roots are.

High altitude UV intensity can burn tender transplants
Harden seedlings slowly and shade-cloth their first week out — high-desert sun is stronger than any indoor start prepares them for.

Alkaline soils limit plant selection without amendment
Test first: knowing your actual pH turns 'what won't grow' into a short, workable amendment list.

Safe to Grow Here?
What the federal record shows across Roosevelt County — and how to grow with it.
We checked the federal record across Roosevelt County — 239 documented sites across 7 of the 9 source types we track.
The most significant on record: 1 Superfund site. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
There's a meaningful federal record across Roosevelt County — worth a look before you plant food, not a reason to hold back from growing. Proximity to a documented site is information, not a diagnosis of any one yard. A soil test before new food beds is the sensible precaution here, and the map shows exactly which sites sit where, so you can see what's actually near you.

A note from Gnorman
What an experienced grower watches for around here
In and around Roosevelt County, two things run higher than the national average — CAFO (9 sites) and Nitrate (138 sites). Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
CAFO: CAFOs pose a different contamination profile than chemical sources.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
Wash all produce consumed raw thoroughly, especially leafy greens grown near CAFOs.
Test well water for nitrate if you rely on a private well for irrigation (EPA standard: 10 mg/L).

Frequently Asked Questions
What hardiness zone is Roosevelt County, New Mexico?
Roosevelt County sits in USDA hardiness zone 7b, per the USDA Plant Hardiness Zone Map 2023. Zones reflect average annual extreme minimum temperatures from 1991–2020 weather data.
Is it too late to plant in Roosevelt County?
For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Feb 9; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 9 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 17 — long-season crops need about 90 days of runway, quick greens only 30. A long window like this one runs successions deep into fall — and even its last weeks take quick greens and garlic.
When does frost risk typically end in Roosevelt County?
The last hard freeze (28°F) in Roosevelt County typically lands around Mar 9, per NOAA 1991–2020 climate normals — an earlier marker than the light-frost dates many planting charts quote. That marks the hard freeze, not the last light frost — light frosts can still bite for a few more weeks, so tender transplants usually wait another 2–3 weeks.
How long is the growing season in Roosevelt County?
Measured between 28°F hard freezes, Roosevelt County sees about 253 frost-free days — roughly Mar 9 through Nov 17, per NOAA 1991–2020 climate normals. Tender crops get a somewhat shorter practical window, since lighter frosts reach a few weeks past the hard-freeze dates on both ends.
What vegetables grow in Roosevelt County?
Roosevelt County's zone 7b supports a wide range — strong performers include Green Chile, Pecan, Pinon Pine, Prickly Pear, and Apache Plume. What actually takes on any one site comes down to its soil, sun, and drainage, and we score each plant against the real conditions at your address.
Which hardiness zone is Roosevelt County, really?
Officially, Roosevelt County sits in USDA zone 7b (USDA PHZM 2023) — but a zone is a 30-year average of winter's coldest night across an area, and it can't see any one yard. A south-facing slope, a tree line, or a low frost pocket can shift a single site by half a zone either way, which is why neighboring gardeners often quote different numbers. We read the conditions at your exact address — soil, sun, slope, and frost — and score 1,112 plants against what's actually there.
Is the soil safe to grow vegetables in Roosevelt County?
The federal record around Roosevelt County is a meaningful one — 239 documented sites — 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.
Just moved to Roosevelt County — what should I know before planting?
Start with three facts. Roosevelt County sits in USDA zone 7b, which sets what survives winter; the last 28°F hard freeze typically clears around Mar 9, with about 253 frost-free days to work with (NOAA 1991–2020 climate normals); and 239 documented sites sit on the federal record here, so a soil test before food beds is the smart first step. From there, matching plants to your actual soil and sun is the fun part.
Everything on this page is a Roosevelt County average. Your yard writes its own version — we read soil, sun, drainage, and frost at your exact address. Try it for 14 days — no card required.
