🌿 About Shallot
Growing Shallot in Arizona: Complete Guide
Shallot (Allium cepa var. aggregatum) is a warm-season crop that needs a head start indoors before Arizona's last frost. Depending on your zone, Arizona gardeners start seeds indoors between September 25, 2026 (Zone 5b) and December 20, 2026 (Zone 10a), then move transplants outside once their zone's last frost has passed — the zone table above has your exact dates.
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 90 days to maturity, Shallot 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.
Shallot requires full sun and regular moisture. In the arid Southwest, intense sun and low humidity mean irrigation is essential; mulch to prevent rapid soil moisture loss.
