Generally — Most Areas
tepary bean (zones 5-11) partially overlaps with New Mexico (4b-8b). It can grow in zones 5-8 within the state.
Your yard isn't the whole zone.
Tepary Bean is grown as an annual, so your winter zone isn't the deciding factor — your frost-free window is, and slope, trees, and low spots move the last-frost date across a single yard. Enter your address and we'll score tepary bean against your parcel's actual frost dates, sun, and soil.

When to Plant Tepary Bean in New Mexico
The frost window
Across New Mexico, the last spring frost clears between Mar 15 and May 30, and the first fall frost lands between Sep 15 and Nov 10 (NOAA Climate Normals 1991-2020). Counting from the latest last frost to the earliest first frost, that's a 108-day window you can count on — up to 240 days on a mild site in a kind year.
Frost tenderness
Tepary Bean is frost-tender — its listed minimum temperature is 46.4°F (USDA PLANTS Database) — so set plants out after the last frost has cleared your local site, not the state's earliest date.
Days to maturity vs. the window
At 90 days to maturity (USDA PLANTS Database), one crop fits New Mexico's 108-day dependable window with 18 days of margin — plant at the front of the window to keep that cushion.
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
Zone compatibility says you can survive winter here. Whether the growing season is long enough — and warm enough — is a different question.
Frost-free days
Tepary Bean wants 60+ frost-free days; a typical New Mexico site sees ~220 (NOAA Climate Normals). That leaves comfortable headroom for succession planting.
Growing degree days
Tepary Bean needs ~1800 GDD (base 50°F) to ripen. The state median runs ~4200 GDD (USDA NRCS county aggregates), so New Mexico's typical season clears that easily.
Climate aggregates derive from USDA NRCS county-level hardiness data + Cornell CALS Extension GDD-by-region tables + MSU Extension chill-hours-by-zone (1991-2020 NOAA Climate Normals baseline).
Soil + Drainage Fit
Tepary Bean likes near-neutral soil (pH 5-8). That's the common-ground band across New Mexico's sandy loam and caliche — a soil test confirms it for your site. Drainage matters: this plant wants well (dry spells). If your New Mexico site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

What Else to Consider
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-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.
Pollinator + Wildlife Value
Tepary Bean draws pollinators (moderate value, USDA PLANTS Database). Planting it near vegetable beds can lift fruit set on neighboring crops.
New Mexico Cooperative Extension
For New Mexico-specific cultivar recommendations, planting calendars, and pest pressure for tepary bean, the canonical source is NMSU Cooperative Extension Service. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Tepary Bean native to New Mexico?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Tepary Bean as native to New Mexico. Planting it supports the pollinators and wildlife that evolved alongside it.

Common Questions About Growing Tepary Bean in New Mexico
When can I plant Tepary Bean in New Mexico?
New Mexico's last spring frost clears between Mar 15 and May 30, and the first fall frost lands between Sep 15 and Nov 10 (NOAA Climate Normals 1991-2020). Tepary Bean is frost-tender — its listed minimum temperature is 46.4°F (USDA PLANTS Database) — so wait until the last frost has cleared your specific site before planting out.
Can Tepary Bean mature before first frost in New Mexico?
Yes — Tepary Bean matures in 90 days (USDA PLANTS Database), and New Mexico's dependable frost-free window runs 108 days (NOAA Climate Normals 1991-2020), leaving 18 days of margin. Plant just after last frost and it ripens ahead of the first fall frost.
What hardiness zone is Tepary Bean grown in across New Mexico?
New Mexico spans USDA hardiness zones 4b-8b (USDA ARS PHZM 2023). Tepary Bean carries a range of zones 5-11, 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 ~220 frost-free days per year (derived from NOAA Climate Normals 1991-2020). Tepary Bean needs 60+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Tepary Bean native to New Mexico?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Tepary Bean as native to New Mexico. Planting it supports the pollinators and wildlife that evolved alongside it.
How should I amend the soil for Tepary Bean in New Mexico?
Tepary Bean prefers pH 5-8 and well (dry spells) drainage (USDA PLANTS Database). 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.
