When to Plant Cabbage in Arizona

Growing Cabbage in Arizona: Complete Guide

Cabbage (Brassica oleracea var. capitata) is a warm-season crop that needs a head start indoors before Arizona's last frost. Most Arizona gardeners begin seeds indoors around Sunday, December 14, 2025 and move transplants outside around Sunday, January 25, 2026, after the risk of frost has passed.

Because Arizona stretches across 10 USDA hardiness zones (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 70 days to maturity, Cabbage needs the indoor head start that Arizona's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Cabbage requires full sun to partial shade 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.
