When to Plant Kohlrabi in Missouri

Growing Kohlrabi in Missouri: Complete Guide

Kohlrabi (Brassica oleracea var. gongylodes) is a warm-season crop that needs a head start indoors before Missouri's last frost. Depending on your zone, Missouri gardeners start seeds indoors between February 20, 2027 (Zone 8a) and March 28, 2027 (Zone 5b), then move transplants outside once their zone's last frost has passed — the zone table above has your exact dates.

Because Missouri stretches across 6 USDA hardiness zones (5b, 6a, 6b, 7a, 7b, 8a), 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 55 days to maturity, Kohlrabi needs the indoor head start that Missouri'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. Midwest growing seasons are compressed between late spring frosts and fall cold snaps, so timing transplants precisely pays off.
