About Turnip

Turnips are one of the most cold-hardy root vegetables — they actually improve in flavor after light frosts. Fast-maturing and dual-purpose: eat the roots and the greens.

Direct sow 4-6 weeks before last frost or in fall 8 weeks before first frost. Thin to 4-6 inches. Harvest roots at 2-3 inches for best flavor — larger roots turn woody. Frost sweetens them.
