Turnips are root vegetables that come in a variety of of sizes, colors and flavors. The turnip is a member of the cabbage family, but unlike most cabbages, it is generally much smaller, with hard, often woody leaves which are unpleasant to eat (woody leaves can be prevented by planting the seeds in early spring or fall). Like most root vegetables, turnips require well-fertilized soil and plenty of sun and water.
Remove weeds and rocks from the garden bed. If the weeds have large root systems, you may need to use a shovel to dig them out.
Add a 1-inch layer of compost to the surface of the soil. Mix it into the soil, either with your hands or with a shovel. If you have a large garden, you can use a tiller.
Rake the soil to give it a flat surface.
Dig trenches of soil ½-inch deep for the seeds. Each trench should be spaced a foot apart.
Sprinkle the seeds ½ inch apart to ensure that the plants have plenty of room to grow. Plant three to four seeds in each section to ensure that a turnip will grow in that spot. If multiple plants grow in one spot, you can pull them out at a later time.
Cover the seeds with soil and water it so it is moist to the touch. Keep the soil moist at all times.
