Notes:

Very easily cultivated fast-growing plants which prefer a rich light soil with ample moisture. They dislike very heavy or acid soils. Plants are susceptible to drought and require irrigation during dry spells in the summer or the root quality will rapidly deteriorate and the plant will go to seed. Radishes are widely cultivated for their edible roots. There are many named varieties that are able to supply edible roots all year round. Radishes are a good companion plant for lettuces, nasturtiums, peas and chervil, tomatoes and cucumbers. They are said to repel cucumber beetles if planted near cucumber plants and they also repel the vine borers which attack squashes, melons. They grow badly with hyssop and grape vines.

Propagation: Seed - sow outdoors in situ in succession from late winter to the middle of summer. Germination takes place within a few days of sowing the seed. If you want a constant supply of the roots then you need to sow seed every 2 - 3 weeks.
