Tips: Radishes like constant moisture. The faster they grow, the better the flavour. Sow seeds thinly, at least ½" deep and firm soil. Rows should be 12-18 inches apart. Radish adapt well to wide row planting (where 2 or 3 rows are planted together) to save space. Small successive sowings made about every 5-7 days will keep a constant supply of fresh radish available throughout the entire growing season.
