When to Plant Garlic in Minnesota

Growing Garlic in Minnesota: Complete Guide

Garlic (Allium sativum) is a crop that grows best when sown directly in the garden. In Minnesota, the right time to direct sow is around Sunday, May 10, 2026, once soil temperatures are consistently warm enough for germination.

Because Minnesota stretches across 5 USDA hardiness zones (3a, 3b, 4a, 4b, 5a), 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 240 days to maturity, Garlic fits comfortably within Minnesota's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.

Garlic requires full sun (6+ hours) and low to moderate moisture. Midwest growing seasons are compressed between late spring frosts and fall cold snaps, so timing transplants precisely pays off.
