About Shallot
Growing Shallot in Oklahoma: Complete Guide
Shallot (Allium cepa var. aggregatum) is a warm-season crop that needs a head start indoors before Oklahoma's last frost. Depending on your zone, Oklahoma gardeners start seeds indoors between October 10, 2026 (Zone 6b) and November 1, 2026 (Zone 8a), then move transplants outside once their zone's last frost has passed — the zone table above has your exact dates.
Because Oklahoma stretches across 4 USDA hardiness zones (6b, 7a, 7b, 8a), planting windows can shift by as much as two to four 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 Oklahoma'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. Great Plains gardens face strong winds and variable moisture — windbreaks and drip irrigation help significantly.
