Nevada is not one climate
A single Nevada answer averages 17 counties whose growing seasons are 211 days apart — from 110 frost-free days in Elko County to 321 in Clark County. Which end of that your land sits nearer changes what jicama can finish before the first hard freeze.
The middle half of 17 counties runs 145–174 days, with a median of 163 days — a 211-day span end to end.

Where in Nevada Fits Best
Jicama is rated for zones 9–12 — a cold floor USDA puts at 20 to 30°F. Against Nevada’s 17 counties that band holds in 1 of them, and the line runs at Clark County (zone 9a), the coldest county still inside it.

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.
Even within Nevada's zones 4a-10a, county microclimates differ enough to change what thrives. These counties carry the closest zone match for jicama (USDA PHZM 2023):

When to Plant Jicama in Nevada
The frost window
Across Nevada, the last spring hard freeze (28°F) clears between Apr 28 and May 20, and the first fall hard freeze lands between Oct 9 and Oct 21 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 142-day window you can count on — up to 176 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 Nevada's late-side last freeze of May 20 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), the fit is tight: Nevada's dependable window runs 142 days. Starting seeds indoors and transplanting at the front of the window banks the difference.
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 Nevada, 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 Nevada site has ~163 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 ~1725 GDD (from PRISM 1991-2020 climate normals), so Nevada'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 Nevada. 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 Nevada 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. Nevada 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 Nevada’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 Nevada — and how to grow with it.
We checked the federal record across Nevada — 16,813 documented sites across 8 of the 9 source types we track.
The most significant on record: 127 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Nevada 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.

What an experienced grower watches for around here
In and around Nevada, Mining runs higher than the national average — 6,064 sites across Nevada. That's not a problem with your land — it's information about it.
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.
Sources: EPA, USGS — 1.8M documented sites tracked nationwide across 9 federal source types.
What Else to Consider for Jicama in Nevada
Zone compatibility tells you about winter cold survival — but Nevada growers also need to think about:
Extremely low rainfall (driest US state)
Alkaline soils (pH 8-9) limit many species
Extreme summer heat in southern valleys
What to actually do about these — and the constraints that apply to every Nevada grower, not just jicama — is covered on the Nevada growing guide.
Timing shifts within Nevada
Jicama needs about 150 days of frost-free season from planting to harvest. 10 of Nevada’s 17 counties give it that outright. The tightest that does is Humboldt County at 161 frost-free days — 11 to spare. Below that line you are transplanting or extending the season, not direct-sowing.
Across Nevada’s 17 counties the frost-free season runs from 110 days in Elko County to 321 days in Clark County — a spread of 211 days, which is why a single statewide planting date misleads. The median Nevada county sees 163 frost-free days, leaving jicama about 13 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 Nevada's frost window — roughly 163 days, opening after the last 28°F freeze (Apr 28 - May 20) and closing at the first (Oct 9 - Oct 21), per NOAA Regional Climate Centers ACIS, 1991-2020.
Nevada Cooperative Extension
For Nevada-specific cultivar recommendations, planting calendars, and pest pressure for jicama, the canonical source is University of Nevada, Reno Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Jicama native to Nevada?
No — the USDA PLANTS Database lists Jicama as introduced rather than native in the Lower 48, so it is not part of Nevada's native flora. It grows here as a garden plant; pairing it with a few Nevada natives keeps local pollinators fed too.

Common Questions About Growing Jicama in Nevada
When can I plant Jicama in Nevada?
Nevada's last spring hard freeze (28°F) clears between Apr 28 and May 20, and the first fall hard freeze lands between Oct 9 and Oct 21 (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 Nevada?
It's close: Jicama needs 150 days to mature (Growable Ground Plant Database) against Nevada's 142-day dependable window (NOAA Regional Climate Centers ACIS, 1991-2020). Start seeds indoors and transplant once the last hard freeze has passed to bank the missing days.
What hardiness zone is Jicama grown in across Nevada?
Nevada spans USDA hardiness zones 4a-10a (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 Nevada site have?
A typical Nevada site sees ~163 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 Nevada?
No — the USDA PLANTS Database lists Jicama as introduced rather than native in the Lower 48, so it is not part of Nevada's native flora. It grows here as a garden plant; pairing it with a few Nevada natives keeps local pollinators fed too.
How should I amend the soil for Jicama in Nevada?
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 Nevada site — amend for drainage and organic matter first.
