About Shallot
Growing Shallot in Michigan: Complete Guide
Shallot (Allium cepa var. aggregatum) is a warm-season crop that needs a head start indoors before Michigan's last frost. Depending on your zone, Michigan gardeners start seeds indoors between September 10, 2026 (Zone 4a) and October 15, 2026 (Zone 7a), then move transplants outside once their zone's last frost has passed — the zone table above has your exact dates.
Because Michigan stretches across 7 USDA hardiness zones (4a, 4b, 5a, 5b, 6a, 6b, 7a), 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 Michigan'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. Midwest growing seasons are compressed between late spring frosts and fall cold snaps, so timing transplants precisely pays off.
