When to Plant Turnip in Indiana

Growing Turnip in Indiana: Complete Guide

Turnip (Brassica rapa) is a crop that grows best when sown directly in the garden. In Indiana, the right time to direct sow is around Monday, March 9, 2026, once soil temperatures are consistently warm enough for germination.

Because Indiana stretches across 4 USDA hardiness zones (5b, 6a, 6b, 7a), 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 91 days to maturity, Turnip fits comfortably within Indiana's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.

Turnip requires full sun and regular moisture. Midwest growing seasons are compressed between late spring frosts and fall cold snaps, so timing transplants precisely pays off.
