A ZIP code or a town gives you its zone, how it moved since 2012, the frost dates at the nearest NOAA station, and the jobs for this month timed from them.

Month by month

What to plant in Nevada this month

The calendar for each of Nevada's main zones, from vegetables to pruning and winter protection, each job tied to the extension page it comes from. Pick a month, or read the whole year below it.

Timed from the median frost dates of the 7 NOAA stations in Nevada’s zone 9b: last spring frost Jan 23, first fall frost Dec 13. Your own ZIP’s frost dates move every window, so the ZIP tool times them for you. The vegetables follow University of Nevada, Reno Extension’s Northern Area (Reno) Planting Schedule for Southern Nevada instead.

Pick a month above to see every job in it.

The 2023 map

Why Nevada’s zones moved

Of the cities above, Las Vegas went from 9a to 9b, Reno went from 7a to 7b, Carson City went from 6b to 7a, Elko went from 5b to 5a and Laughlin went from 10a to 9b.

The USDA explains the national picture: “When compared to the 2012 map, the 2023 version reveals that about half of the country shifted to the next warmer half zone, and the other half of the country remained in the same half zone.” The new map uses 1991 to 2020 and more than 13,000 weather stations, so it draws Nevada’s hills, valleys and cities more finely than the 2012 map did.

A warmer zone changes which perennials and shrubs come through the winter, not when the garden gets planted; that still follows the frost dates.

Garlic goes in around the first fall frost, from about two weeks before it to three weeks after, so the cloves root before the ground freezes. Hardneck types suit a cold winter and softneck types a mild one. “Planting the Garlic” by Dwight Sipler from Stow, MA, USA, CC BY 2.0
