Root vegetables are underground plant parts used as vegetables. They are called root vegetables for lack of a better generic term but include both true roots such as tuberous roots and taproots. Root crops all need a loose, friable soil, and compost, manure or other soil conditioners can be incorporated into the garden before planting to improve the quality of both the soil and the roots to be harvested. Carrot, Beetroot, Radish are one of the best examples of root vegetables.
