When to Plant Kohlrabi in Nebraska

Growing Kohlrabi in Nebraska: Complete Guide

Kohlrabi (Brassica oleracea var. gongylodes) is a warm-season crop that needs a head start indoors before Nebraska's last frost. Depending on your zone, Nebraska gardeners start seeds indoors between March 23, 2027 (Zone 6a) and April 12, 2027 (Zone 5a), then move transplants outside once their zone's last frost has passed — the zone table above has your exact dates.

Because Nebraska stretches across 3 USDA hardiness zones (5a, 5b, 6a), 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 55 days to maturity, Kohlrabi needs the indoor head start that Nebraska's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Kohlrabi requires full sun to partial shade and regular (consistent moisture prevents cracking) moisture. Great Plains gardens face strong winds and variable moisture — windbreaks and drip irrigation help significantly.
