Growing Asparagus 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), asparagus can go out around April — approximately 2 weeks before the last expected frost, making it an early-season opportunity.

Asparagus thrives between 50°F and 85°F. It tolerates temperatures as low as 28°F, making it a candidate for early spring planting before the last frost date. Expect 365–730 days from transplant to first harvest. Perennial — plant crowns and wait 2 years for first harvest. Produces for 20+ years.
