Sow small amounts each time You sow, because this radish variety gets a lot bigger than other varieties. Sow outdoors from the middle of June till the beginning of September. Sow thinly and sparsely and cover the seeds with a thin layer of soil. Keep about 10 - 15 cm between the seeds. And about 25 cm between the rows.
