When to Plant Cauliflower in Nevada

Growing Cauliflower in Nevada: Complete Guide

Cauliflower (Brassica oleracea var. botrytis) is a warm-season crop that needs a head start indoors before Nevada's last frost. Most Nevada gardeners begin seeds indoors around Tuesday, December 30, 2025 and move transplants outside around Tuesday, February 10, 2026, after the risk of frost has passed.

Because Nevada stretches across 11 USDA hardiness zones (5a, 5b, 6a, 6b, 7a, 7b, 8a, 8b, 9a, 9b, 10a), planting windows can shift by as much as six to eight weeks from one end of the state to the other. Gardeners in the warmer southern zones can start earlier, while those in cooler northern zones should wait until the zone table above shows their last frost has passed.

With 75 days to maturity, Cauliflower needs the indoor head start that Nevada's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Cauliflower requires full sun (6 hours) and regular (1-1.5 inches/week) moisture. In the arid Southwest, intense sun and low humidity mean irrigation is essential; mulch to prevent rapid soil moisture loss.
