Growing Turnip 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), turnip can go out around March — approximately 6 weeks before the last expected frost, making it an early-season opportunity.
Turnip thrives between 40°F and 65°F. It tolerates temperatures as low as 28°F, making it a candidate for early spring planting before the last frost date. Expect 35–60 days from transplant to first harvest. Fast cool-season root. Both roots and greens are edible.
