When to Plant Turnips in Louisiana

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

The Short Answer

In Louisiana, soil conditions are an important factor for turnips. Rich alluvial soils in river valleys. Heavy clay in many areas. Acidic throughout. Sandy in some coastal areas. Direct sow 3 weeks before your last frost date. Turnips can also be planted in fall, 8 weeks before your first frost.

Growing Turnips in Louisiana

Turnips in Louisiana's Climate

Turnips are a productive cool-season crop in your climate. Sow from September through February. Both roots and greens are staples of Southern cooking — turnip greens cooked with ham hock is a classic. Frost sweetens both roots and greens.

Soil Considerations for Louisiana

Rich alluvial soils in river valleys. Heavy clay in many areas. Acidic throughout. Sandy in some coastal areas. Loose, well-drained soil is especially important for turnips since the edible portion grows underground. If your soil is heavy clay, consider raised beds.

Louisiana Climate & Growing Season

Subtropical. Long growing season. Very hot and humid summers — some crops need shade. Year-round gardening possible. Turnips can handle frost well, which is an advantage in Louisiana's climate. You can push planting dates earlier in spring and extend into fall.

Growing season length varies across Louisiana: Northern Louisiana (8a, 8b) has a last frost around Mar 1 - Mar 15, while Southern Louisiana (9a, 9b) sees frost end around Feb 1 - Feb 20. This difference matters for turnips — but turnips handle frost well, so the timing difference is less critical.

Growing Tips

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

The Bottom Line

Turnips can be grown successfully across Louisiana, but your exact planting dates depend on which region you're in. Northern Louisiana gardeners should plan around a Mar 1 - Mar 15 last frost, while those in Southern Louisiana can typically plant earlier.
