The main root crops profiled here belong to several families, so their specific needs differ in various ways. Radishes, swedes and turnips are brassicas, sharing vulnerability to family problems like clubroot as well as a dislike of acid or dry soils. Most other roots enjoy well-broken, slightly acid soil with good drainage and fairly high nutrient residues from a previous crop, and fit well in rotations after legumes and brassicas. To avoid root distortion during transplanting, they are generally sown direct, in a deep, finely tilthed seedbed free from stones, although some varieties can be multi-sown in modules. Potatoes like rich, well-manured ground and are often planted on their own as a separate rotation course. (See also alternative root crops, page 180.)
