When to Plant Shallot in Michigan

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. Most Michigan gardeners begin seeds indoors around Wednesday, February 18, 2026 and move transplants outside around Wednesday, April 29, 2026, after the risk of frost has passed.

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.
