Growing Turnips in Ohio
State-Specific Growing Tips
Spring: direct sow 3 weeks before last frost. Fall: sow in late August for harvest sweetened by frost. Turnips handle Ohio's clay reasonably well — better than carrots, similar to beets. Harvest roots at 2-3 inches for tenderness. Fall turnips taste noticeably sweeter after frost exposure.
Recommended Varieties for Ohio
Purple Top White Globe (classic). Hakurei (Japanese salad turnip — sweet, tender, fast). Tokyo Cross. Ohio State Extension recommends turnips as an easy, underutilized cool-season root crop.
