Generally — Most Areas
caraway (zones 3-7) suits most of Nevada (4a-10a) — zones 4-7 are in range, and the rest of the state is the exception.
Your yard isn't the whole zone.
Nevada spans zones 4a-10a, but your yard has its own microclimate — slope, trees, and low spots shift frost and sun across a single parcel. Enter your address and we'll score caraway against your land's actual soil, sun, and frost.

When to Plant Caraway 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.
Frost tenderness
Caraway is frost-tender — its listed minimum temperature is 44.6°F (USDA PLANTS Database) — so set plants out two to three weeks PAST your local last hard freeze, not on it and not on the state's earliest date. The 28°F marker above is when killing freezes stop, not when light frost does.
When to start the seed
Caraway is direct-sown where it grows rather than started under cover, so there is no seed-tray head start to bank — Nevada's dates above are the whole calendar for it. That makes the last-freeze date the binding constraint, and a warmer pocket of your own yard is worth more to this crop than it is to a transplanted one.
Days to maturity vs. the window
At 240 days to maturity (USDA PLANTS Database), even Nevada's kindest 176-day season runs short — challenging without season extension. An indoor start plus row cover on both shoulders of the season closes the gap.
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 caraway survives winter in part of Nevada, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Caraway wants 150+ frost-free days; a typical Nevada site sees ~163 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves a tight window — use transplants and pick early-maturing cultivars.
Growing degree days
Caraway needs ~1500 GDD (base 50°F) to ripen. The state median runs ~1725 GDD (from PRISM 1991-2020 climate normals), so Nevada sits right at the threshold — pay attention to siting and microclimate.
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
Caraway tolerates a wide pH range (pH 4.8-7.8) — 3 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 and 7 — worth knowing before you decide whether a Nevada soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Nevada site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

What Else to Consider for Caraway 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 caraway — is covered on the Nevada growing guide.
Timing shifts within Nevada
Caraway needs about 150 days of frost-free season to complete its cycle. 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 caraway 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"). Caraway's 150-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Where in Nevada Fits Best
Even within Nevada's zones 4a-10a, county microclimates differ enough to change what thrives. These counties carry the closest zone match for caraway (USDA PHZM 2023):
Pollinator + Wildlife Value
Caraway draws honeybees and native bees (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, caraway 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.

Common Questions About Growing Caraway in Nevada
When can I plant Caraway 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). Caraway is frost-tender — its listed minimum temperature is 44.6°F (USDA PLANTS Database) — so wait two to three weeks past your site's last hard freeze, when light frost has also stopped, before planting out.
Can Caraway mature before first frost in Nevada?
Caraway needs 240 days to mature (USDA PLANTS Database), and even Nevada's longest typical season runs 176 days (NOAA Regional Climate Centers ACIS, 1991-2020) — challenging without season extension. An indoor start plus row cover on both season shoulders closes the gap.
What hardiness zone is Caraway grown in across Nevada?
Nevada spans USDA hardiness zones 4a-10a (USDA ARS PHZM 2023). Caraway carries a range of zones 3-7, 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). Caraway needs 150+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
How should I amend the soil for Caraway in Nevada?
Caraway tolerates pH 4.8-7.8 and well (dry spells) drainage (FAO ECOCROP). That is a 3-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.
Will Caraway actually grow on my specific land in Nevada?
