When to plant lettuce in Nevada — sow, transplant & harvest dates

Nevada is mostly USDA zone 7a (range 4b-10a). Dates below are derived from lettuce's frost tolerance and Nevada's frost window — not generic national averages.

Lettuce planting timetable for Nevada

Stage	When in Nevada	Anchor
Start seeds indoors	mid-March (March 18)	4 weeks before the last frost (mid-April)
Transplant outside	late March (March 25)	21 days before the last frost (mid-April)
First harvest (estimate)	mid-May (May 14)	~50 days from transplant

Dates are state-wide averages for the dominant zone. Local microclimates — elevation, urban heat, coastal moderation — can shift the window by 1-2 weeks. Use the frost-date calculator for a date tuned to your town.

Why Nevada's climate shifts the lettuce dates

Nevada's last spring frost averages mid-April and first fall frost late October, which sets the whole planting clock. Nevada is a high-desert state with dramatic elevation swings. The southern Mojave is nearly frost-free; the northern basin is cold and short-season. Sow early — lettuce bolt once daytime temperatures hold above 24 °C, so the earlier they go in, the longer the harvest.

Lettuce is genuinely cold-hardy — direct-sow as soon as soil can be worked, 2-4 weeks before the last spring frost. It bolts and turns bitter in summer heat above 24 °C, so southern zones grow it as a winter and shoulder-season crop instead of in midsummer.

Frost-risk note

Don't plant before mid-April — a hard freeze can still set young plants back. In the high northern Great Basin near Elko (zone 4b) the safe date runs a week or two later.

Regional variation within Nevada

the high northern Great Basin near Elko (zone 4b) runs roughly 1-2 weeks behind the state average; the Mojave around Las Vegas (zone 10a) can plant 1-2 weeks earlier.

Las Vegas — USDA zone 9a
Reno — USDA zone 7a
Henderson — USDA zone 9a
Carson City — USDA zone 7a
Elko — USDA zone 6a

What else to plant in Nevada around then

The same early window suits peas, lettuce, spinach, and onion sets.

Frequently asked questions

When is the best time to plant lettuce in Nevada?

In Nevada (mostly USDA zone 7a), sow lettuce indoors around mid-March, transplant outdoors late March (before the last frost, mid-April), and harvest from mid-May. Lettuce are cold-hardy — they tolerate frost and actively prefer cool weather, so they go in well before the last spring frost and bolt in summer heat.

What USDA zone is Nevada?

Most of Nevada sits in USDA hardiness zone 7a, with the state spanning roughly 4b-10a from the high northern Great Basin near Elko (zone 4b) to the Mojave around Las Vegas (zone 10a). The last spring frost averages mid-April and the first fall frost late October.

Can you grow lettuce in Nevada?

Yes. Nevada's dominant zone 7a supports lettuce — the key is timing. Lettuce are cold-hardy — they tolerate frost and actively prefer cool weather, so they go in well before the last spring frost and bolt in summer heat.

Does the planting date change across Nevada?

the high northern Great Basin near Elko (zone 4b) runs roughly 1-2 weeks behind the state average; the Mojave around Las Vegas (zone 10a) can plant 1-2 weeks earlier.

What else can I plant in Nevada around the same time?

The same early window suits peas, lettuce, spinach, and onion sets.
