New Mexico is not one climate
A single New Mexico answer averages 33 counties whose growing seasons are 120 days apart — from 144 frost-free days in Catron County to 264 in Doña Ana County. Which end of that your land sits nearer changes what jicama can finish before the first hard freeze.
The middle half of 33 counties runs 186–221 days, with a median of 209 days — a 120-day span end to end.

Quartiles are order statistics — every figure shown is a value a real county recorded, not an interpolation. Your own site sits somewhere inside this range; a parcel report resolves where.
Where Jicama Stands in New Mexico
Jicama is rated for zones 9–12 — a cold floor USDA puts at 20 to 30°F. No New Mexico county sits inside it, so in open ground this is a grown-under-cover plant here rather than a bed plant — which is a statement about New Mexico winters, not about jicama.

County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. A zone is a 10°F band of average annual extreme minimum temperature, so the floor above is the band the plant's rating denotes, not a single measured kill point. Slope, shelter and cold-air drainage routinely move a site half a zone either way from its county figure — which is the part only your address resolves.

When to Plant Jicama 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.
When to start the seed
Those dates are when jicama goes out, not when it starts. It is sown under cover about 4 weeks ahead, so counting back from New Mexico's late-side last freeze of Apr 19 is what fixes your sowing date — and a yard that clears frost earlier than the state's late date starts earlier still.
Days to maturity vs. the window
At 150 days to maturity (Growable Ground Plant Database), counting from the last hard freeze it ripens with 36 days to spare even in New Mexico's tightest freeze scenario — room for a later start or a second sowing.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: Growable Ground Plant Database — frost-free days from FAO ECOCROP, days to harvest from university Extension production guides, and growing-degree-day and chill-hour minimums that are compilation estimates rather than published figures. 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 jicama survives winter in part of New Mexico, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Days to maturity
Jicama matures in ~150 days (Growable Ground Plant Database). A typical New Mexico site has ~209 frost-free days, so one full crop fits, with little room for replant.
Growing degree days
Jicama needs ~3500 GDD (base 50°F) to ripen. The state median runs ~2899 GDD (from PRISM 1991-2020 climate normals), so New Mexico's typical season runs short on heat — pick a south-facing site and consider season extension.
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
Jicama tolerates a wide pH range (pH 4.3-8) — 3.7 units, acid ground through alkaline — so soil acidity is rarely what limits it in New Mexico. A soil test is still worth having, but for what else it tells you about this site, not to clear this plant. It will grow across that whole span, but it does best between pH 6.5 and 8 — worth knowing before you decide whether a New Mexico soil test result is a problem or just a number.

Drainage: FAO ECOCROP, with the remaining rows from other published sources or Growable Ground compilation. New Mexico soil profile from USDA NRCS SSURGO. Site-specific verification: a 30-minute soil test from your local Extension lab.
Before you plant jicama for food
Anything you grow to eat takes up what is in the ground it grows in, so what is on record near you is worth knowing before jicama goes in. What follows is New Mexico’s documented federal record at state scale — a screening signal, not a soil test, and not a statement about any one lot.
Safe to Grow Here?
What the federal record shows across New Mexico — and how to grow with it.
We checked the federal record across New Mexico — 19,441 documented sites across 8 of the 9 source types we track.
The most significant on record: 230 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
New Mexico carries one of the heavier federal records we track — and that's not a verdict on your yard. Proximity to a documented site is information, not a diagnosis: nothing here says any particular parcel is affected. It does earn one concrete step — before food beds go in the ground, a professional soil test tells you exactly what you're working with, and raised beds with clean imported soil grow well almost anywhere in the meantime.

A note from Gnorman
What an experienced grower watches for around here
In and around New Mexico, two things run higher than the national average across New Mexico — Nitrate (8,470 sites) and Mining (1,718 sites). Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
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 well water for nitrate if you rely on a private well for irrigation (EPA standard: 10 mg/L).
Test soil for heavy metals (lead, arsenic, cadmium, mercury) — this is essential near any mining site.
Sources: EPA, USGS — 1.8M documented sites tracked nationwide across 9 federal source types.
What Else to Consider for Jicama 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
What to actually do about these — and the constraints that apply to every New Mexico grower, not just jicama — is covered on the New Mexico growing guide.
Timing shifts within New Mexico
Jicama needs about 150 days of frost-free season from planting to harvest. 32 of New Mexico’s 33 counties give it that outright. The tightest that does is Cibola County at 150 frost-free days — 0 to spare. Below that line you are transplanting or extending the season, not direct-sowing.
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, leaving jicama about 59 days of slack on a typical parcel — room for a second sowing where the season runs long.
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"). Jicama's 150-day requirement: USDA PLANTS / Growable Ground plant database (days to maturity). A parcel report resolves your address's own frost dates.
Pollinator + Wildlife Value
Jicama draws honeybees and native bees (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, jicama can only work that bloom inside New Mexico's frost window — roughly 209 days, opening after the last 28°F freeze (Mar 31 - Apr 19) and closing at the first (Oct 22 - Nov 9), per NOAA Regional Climate Centers ACIS, 1991-2020.
New Mexico Cooperative Extension
For New Mexico-specific cultivar recommendations, planting calendars, and pest pressure for jicama, the canonical source is NMSU Cooperative Extension Service. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Jicama native to New Mexico?
No — the USDA PLANTS Database lists Jicama as introduced rather than native in the Lower 48, so it is not part of New Mexico's native flora. It grows here as a garden plant; pairing it with a few New Mexico natives keeps local pollinators fed too.

Common Questions About Growing Jicama in New Mexico
When can I plant Jicama 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). Time outdoor planting to after the last hard freeze for your specific site — a further two to three weeks for anything tender — and count back from those dates for transplant scheduling.
Can Jicama mature before first frost in New Mexico?
Yes — Jicama matures in 150 days (Growable Ground Plant Database), and New Mexico's dependable hard-freeze-free window runs 186 days (NOAA Regional Climate Centers ACIS, 1991-2020), leaving 36 days of margin. Plant once the last hard freeze has passed — two to three weeks later for anything tender — and it ripens ahead of the first fall freeze.
What hardiness zone is Jicama grown in across New Mexico?
New Mexico spans USDA hardiness zones 5a-9a (USDA ARS PHZM 2023). Jicama carries a range of zones 9-12, 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). Jicama should be matched against that window, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Jicama native to New Mexico?
No — the USDA PLANTS Database lists Jicama as introduced rather than native in the Lower 48, so it is not part of New Mexico's native flora. It grows here as a garden plant; pairing it with a few New Mexico natives keeps local pollinators fed too.
How should I amend the soil for Jicama in New Mexico?
Jicama tolerates pH 4.3-8 (FAO ECOCROP). That is a 3.7-unit span, acid ground through alkaline, so pH is rarely what limits this plant on a New Mexico site — amend for drainage and organic matter first.
Will Jicama actually grow on my specific land in New Mexico?
