When to Plant Cabbage in North Dakota

Growing Cabbage in North Dakota: Complete Guide

Cabbage (Brassica oleracea var. capitata) is a warm-season crop that needs a head start indoors before North Dakota's last frost. Depending on your zone, North Dakota gardeners start seeds indoors between March 24, 2027 (Zone 4b) 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 North Dakota stretches across 3 USDA hardiness zones (3b, 4a, 4b), planting windows can shift by as much as two to four 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 North Dakota'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. Great Plains gardens face strong winds and variable moisture — windbreaks and drip irrigation help significantly.
