Northern Nevada 123 frost-free days

May 15 last frost spring release Sep 15 first frost fall limit

UNR Extension says northern Nevada can grow vegetables in three seasons: early spring, summer, and early fall.
Use the average last spring frost of May 15 and the earliest fall frost of Sept. 15 as planning examples, while treating 90 days frost-free as the safer baseline.
The Reno area has many microclimates, so planting dates may differ by several days to two weeks.

Source-backed timing May 15 last spring frost and September 15 earliest fall frost from the northern Nevada guide.

North valleys and exposed sites can run colder; use local records when they are available.

The Reno area has many microclimates, so planting dates may differ by several days to two weeks.
UNR notes the north valleys average 5 to 10 degrees F colder than Reno, so planting should be delayed by 1 to 2 weeks there.

St. Patrick's Day is the traditional start for cool-season peas and spinach in northern Nevada.
Direct-seed other cool-season crops such as lettuce, Swiss chard, beets, and carrots until the end of May.
Set warm-season transplants such as tomatoes, eggplant, peppers, watermelon, and squash after the last frost in May to early June.
Start a second season of cool-season vegetables in August for autumn harvest and possible protected overwintering.
Plant very hardy crops as soon as the soil can be worked; plant semi-hardy crops 2 to 4 weeks before the May 15 average last killing frost.
Do not push heat-sensitive cole crops such as broccoli, cauliflower, Brussels sprouts, and cabbage after mid-May.
Use row covers, hotcaps, or similar protection if frost-tender crops go out before danger of frost is past.
Use succession planting for beans, carrots, broccoli, endive, lettuce, radishes, cabbage, turnips, corn, and beets.
