McDermitt, Nevada, sits in USDA hardiness zone 6a — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
Among the crops suited to this profile: cabbage, blackberry, california poppy, and collard greens. The site-level story — soil, sun, drainage — decides the rest.
Even in McDermitt, no two yards are alike.
A low spot, a south-facing slope, or a stand of trees moves the frost date and sun across a single McDermitt lot. Enter your address and we'll score 1,086 plants against your land's actual soil, sun, and frost.

What this means for growing in McDermitt
Each reading below is measured for McDermitt itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredMcDermitt runs about 126 days between hard freezes — a short growing season.
Long-maturing crops like melons, sweet potatoes, and winter squash can run out of runway before the first hard freeze, ripening late or not at all.
Lead with fast-maturing varieties, and stretch the season on both ends with cold frames, low tunnels, or a greenhouse.

Winter hardiness
MeasuredMcDermitt sits in USDA hardiness zone 6a.
The zone sets which perennials, shrubs, and fruit trees live through an average winter here — a plant rated for a colder zone is a safe bet, one rated warmer needs winter protection or gets treated as an annual.
Match perennials and fruit to the zone before you buy, so nothing you plant is a gamble against the cold.

The kind of country McDermitt is in
McDermitt sits in the Northern Basin and Range — EPA Level III, inside the wider North American Deserts. That is read at McDermitt's own centroid, and it is not what its county reads: Humboldt County is mostly Central Basin and Range. The wider page above you is answering a different question about different ground.

Is it too late to plant in McDermitt?
Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Apr 22; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 20 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Sep 23 — long-season crops need about 90 days of runway, quick greens only 30. When the window is tight, the fall moves are quick ones — baby greens, radishes, and garlic set for next season.

What an experienced grower watches for around here
In and around McDermitt, two things run higher than the national average within ~10 miles of McDermitt — Mining (10 sites) and Nitrate (12 sites). Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Mining: Mining sites — both historic and active — can leach heavy metals (arsenic, lead, cadmium, mercury) into soil and water for centuries after operations cease.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
Test soil for heavy metals (lead, arsenic, cadmium, mercury) — this is essential near any mining site.
Test well water for nitrate if you rely on a private well for irrigation (EPA standard: 10 mg/L).

Your land is one point inside McDermitt
Everything above resolves to McDermitt as a whole — one PHZM band and one 28°F frost record, read across 1K acres. Your parcel is one point inside that footprint. Slope, tree cover, a low spot that pools cold air, and what is in the soil are all resolved at the address, and none of them are visible at town scale. That is the honest boundary of this page, and the reason the next step is a reading of your own ground rather than a better local average.

How we know this about McDermitt
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this town’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals at McDermitt’s own record; boundaries and acreage from US Census TIGER/Line 2025; the contamination records from the federal sources named in their beats above. Soil is not read at town grain anywhere on this page — there is no town-resolution survey in our data, which is why you will find no soil grid here rather than a statewide one wearing a local label. The resolution ledger below names every figure this page inherited.
Common questions about McDermitt
When does frost risk typically end in McDermitt?
The last hard freeze (28°F) in McDermitt typically lands around May 20, per NOAA 1991–2020 climate normals — earlier than the light-frost dates most charts quote. That marks the hard freeze, not the last light frost — lighter frosts keep biting past it, which is why tender transplants here wait until about Jun 10.
When is the first frost in McDermitt?
The first hard freeze (28°F) in McDermitt typically arrives around Sep 23, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 9, so the watching starts about Aug 24 — about 126 days after the spring freeze cleared.
How long is the growing season in McDermitt?
Measured between 28°F hard freezes, McDermitt sees about 126 frost-free days — roughly May 20 through Sep 23, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 10 to Sep 9, about 91 days.
Is the soil safe to grow vegetables in McDermitt?
The federal record around McDermitt is a meaningful one — 31 documented sites, mostly Nitrate entries (12), the nearest Nitrate record about 0.2 miles out — 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.
How do gardeners stretch the season in McDermitt?
With about 126 frost-free days between hard freezes, McDermitt rewards the classic extension moves: floating row cover buys roughly two to four extra weeks at each shoulder — on this season that is a working window nearer 154 to 182 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the May 20 hard-freeze normal stretches the season without touching the calendar.
Everything above is measured at McDermitt's scale — its 6a band and its 126-day season. Your yard writes its own version of McDermitt's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
