Seedlings take place between May and September, directly outdoors. Thin the radishes to 3 inches apart when the seedlings appear, keeping the most resistant. Regular watering is essential to keep the soil cool. Harvesting takes place from September to December when the radishes start to sprout. Then leave them to dry for long time storing.

As with many vegetables, black radishes is hardly affected by diseases, but nevertheless can be attacked by the flea beetle (an insect that eats the leaves of the plant, leaving small holes on the leaves). Subsequently this pest causes a slower growth of the plant, which can even lead to the death of the latter. To address the problem, spray some water on the leaves as the flea beetle does not like water. An excellent winter vegetable, black radish is not only a vegetable but also a root.
