Growing Swiss Chard 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), swiss chard can go out around April — approximately 4 weeks before the last expected frost, making it an early-season opportunity. Starting seeds indoors 4 weeks before the last frost date gives you a significant head start.

Swiss Chard thrives between 50°F and 80°F. It tolerates temperatures as low as 28°F, making it a candidate for early spring planting before the last frost date. Expect 50–60 days from transplant to first harvest. Tolerates heat and mild frost.
