When to Plant Turnips in Ohio

A fast-growing, cold-hardy root crop that's underappreciated. Both the root and the greens are delicious.

The Short Answer

Turnips are an underappreciated gem in the Ohio garden — fast-growing, cold-hardy, and productive in both root and green form. They fill the cool-season gap nicely and can be one of the first and last crops of the Ohio year.

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.

Common Challenges in Ohio

Flea beetles on leaves. Cabbage root maggot. Bolting in summer heat. Minimal disease issues.

Growing Tips

Great for spring and fall planting. Harvest small for tender roots. Fall-planted turnips taste sweeter after a frost.

Companion Planting

Plant turnips alongside these companions for better growth:

Peas Onions

Timing varies across the state — Northern Ohio gardeners work with a last frost around May 1 - May 15, while Southern Ohio sees frost end around Apr 15 - Apr 30.
