Radish

sown, roots and plants

RADISH, several species of herbs of the family Brassicareat. The common garden radish (Raphanus rativar) is thought to be a native of Asia, but is not known in a wild state. It is-cultivated for its edible roots, which in various varieties may be red, white, gray, brown or black, and vary in form from turnip shaped to parsnip-shaped. They reach edible maturity in from three weeks or less when forced. Radishes thrive best in rich, light, well-drained sandy loam. Out of doors the seed may be sown as soon as the soil can be worked, since the plants are very hardy. The seeds may be dropped about an inch apart, covered an inch deep, in rows a foot asunder in beds by themselves, or, as in market garden practice, may be sown between slower-growing crops, such as carrots, cabbage or peas. Some times they are even sown with the seed of parsnips, onions and other crops that are either slow to germinate or that are very in conspicuous when they first appear. They then serve to indicate the positions of the rows, so that cultivation of the other plants may be gin much earlier; they must then be removed promptly to prevent injuring the main crop. For succession, the seed should be planted at intervals of a week or 10 days. Winter rad

ishes are sown from midsummer to early autumn, and when cold weather arrives are stored in pits or cellars like other roots. Clean cultivation is essential. A Japanese, species (R. eaudatas) is popularly cultivated in Asia for its long pods which are eaten raw or • pickled. It is known as the serpent or rat-tailed radish. The pods are often a foot lop& The roots are small, hard and inedible. The sea radish (R. maritinsas) is more pungent than the garden species and is little known in American gar. dens. Horseradish (q.v.) belongs to a; dif4 ferent genus, Arasoraesa.
