When to Plant Cabbage in Wisconsin

Growing Cabbage in Wisconsin: Complete Guide

Cabbage (Brassica oleracea var. capitata) is a warm-season crop that needs a head start indoors before Wisconsin's last frost. Depending on your zone, Wisconsin gardeners start seeds indoors between March 9, 2027 (Zone 6a) and April 8, 2027 (Zone 3b), then move transplants outside once their zone's last frost has passed — the zone table above has your exact dates.

Because Wisconsin stretches across 6 USDA hardiness zones (3b, 4a, 4b, 5a, 5b, 6a), 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 70 days to maturity, Cabbage needs the indoor head start that Wisconsin's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Cabbage requires full sun to partial shade and regular (1-1.5 inches/week) moisture. Midwest growing seasons are compressed between late spring frosts and fall cold snaps, so timing transplants precisely pays off.
