Turnips are very hardy and can be planted early in the spring. Use a loose, not too acid soil (add lime if too acid). Mulching always benefits turnips. Best flavor is when they grow fast - to do this you need good soil with a lot of organic matter and adequate water.
If you allow the roots to grow too large they will become woody, stringy, and bitter. They do not stand well in the ground, so pull the roots for storage.. If storing, top them and store in a cool place.
Turnip roots and greens are nutritious and tasty. The roots are eaten raw, pickled, braised, or pureed. Use them alone, in soups, stews, and casseroles. The leaves make a good potherb. Sprouted seeds can be eaten in salads or sandwiches.
