Radishes 'Pink Beauty' (Radishes)

Radishes grow best in cool, moist weather (50 - 65F/10 - 18C). Late plantings may bolt before edible root forms, and hot weather reduces quality and increases pungency. Direct seed 1/2 inch (1.2 cm) deep, 1 inch (2 cm) apart, in rows 12 inches (30 cm) apart about 3 to 6 weeks before average last frost. Thin to about 2-inch (5 cm) spacings, as crowded plants may not produce high-quality roots. Thinnings, both root and greens, can be used as salad. Gardeners often use quick-germinating radish to mark rows where other slower germinating seeds are planted. Make additional plantings every 1 - 2 weeks until temperatures average in the mid 60s F (16C) for continuous harvest, or plant varieties with different maturity dates in a single planting. When weather cools in fall, resume planting.

Most winter varieties need more space than spring radish varieties so thin to about 6 inch (15 cm) spacings, depending on variety.
Winter crops should be planted so that they mature around the first fall frost date, as frost improves flavor and texture.
For uninterrupted growth and best quality, keep soil moist and with little nitrogen fertilizer or manure. Radishes are good neighbors for carrots, parsnip, parsley and other slow-germinating crops, since they help to break soil crust for the weaker and later-germinating crops.
Due to their fast maturity rate, radishes are good intercrops along with cabbage, tomato or squash family groups. Avoid planting radishes or other cole crops in the same location more than once every 3 - 4 years to help reduce disease.
