They reached Mexico in 1586, Virginia in 1610, and New England in 1628. Many types are grown, differing chiefly in the shape and color of the root.
Turnips are easy to grow.
They mature in two months and may be planted early in the spring or fall for roots and greens. The spring crop is planted for summer use. The fall crop, which is usually larger and of higher quality than the spring crop, may be used from the field all winter or may be stored for winter use. Turnips are a good winter cover crop for the garden. A severe winter may kill off the greens, but the roots will still be of good quality.
