Space the trenches 12 to 24 inches apart. Sow purple top turnip seeds about 1 inch apart in the trenches, four to six weeks before the last frost for harvest in late spring, covering the seeds lightly with soil.

You must plant them so that you have 45 to 65 days before daytime temperatures reach 75 degrees Fahrenheit.
Maturation from seed varies from 28 days to 75 days. The larger varieties take longer to reach full size. You can also take them when they are small for a sweeter, milder flavor. Turnips are seeded in spring or fall, but the fall crops need to be harvested before heavy freezes.
