Growing Garlic in Minneapolis

Minneapolis's Zone 4b climate presents a genuine gardening challenge: a compressed season of roughly 140 days between the last frost in May and the first in October. Cold winters are part of daily life, but the long summer daylight hours accelerate plant growth remarkably. Start warm-season crops indoors in early April, use season extension tools liberally, and choose short-season varieties to maximize the window.

In Minneapolis (last frost around May 11), garlic can go out around December — approximately 20 weeks before the last expected frost, making it an early-season opportunity.

Garlic thrives between 35°F and 70°F. It tolerates temperatures as low as 20°F, making it a candidate for early spring planting before the last frost date. Expect 240–270 days from transplant to first harvest. Plant in fall, harvest next summer.
