Cool-season crops do beautifully in Tucson's mild winters, and the monsoon rains from July through September can extend the warm-season growing period.

In Tucson (last frost around February 5), cabbage can go out around December — approximately 6 weeks before the last expected frost, making it an early-season opportunity. Starting seeds indoors 6 weeks before the last frost date gives you a significant head start.
