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), aim to direct sow or transplant blueberry outside around February — approximately 2 weeks after your last expected frost.
