When to Plant Rutabaga in Missouri

Growing Rutabaga in Missouri: Complete Guide

Rutabaga (Brassica napus var. napobrassica) is a crop that grows best when sown directly in the garden. Depending on your zone, the right time to direct sow in Missouri falls between December 12, 2026 (Zone 8a) and January 17, 2027 (Zone 5b), once soil temperatures are consistently warm enough for germination.

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 90 days to maturity, Rutabaga fits comfortably within Missouri's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.

Rutabaga requires full sun (6+ hours) and regular (1 inch/week) moisture. Midwest growing seasons are compressed between late spring frosts and fall cold snaps, so timing transplants precisely pays off.
