When to Plant in Las Vegas, NV

Las Vegas is in the Mojave Desert — Zone 9a with a last frost around February 16. Summer temperatures regularly reach 115°F, making June through August essentially impossible for most vegetables. Like Phoenix, Las Vegas gardening is best in fall through spring.

Las Vegas gardeners follow a reverse-season calendar. The prime growing windows are fall (September–November) and spring (February–April). Winter is actually excellent for cool-season crops. Water management is critical in the desert.

This month in Las Vegas: November 2026

Las Vegas's first frost usually holds off until around November 27, so November is one of the best growing months of the year. The cool-season crops planted in October are filling out now.

Keep sowing lettuce, spinach, radishes, and carrots in the first half of the month for winter picking. Garlic and onion transplants can still go in. Pull the tomatoes once they stop setting fruit.

As the days cool, cut back on watering; the soil stays wet much longer now than it did in October. Have a frost cloth ready for late in the month, and put it on in the evening when the forecast drops below freezing.
