Radish Planting Instructions

Radishes grow best in cool (50 F to 65 F), moist weather. Hot weather reduces quality and increases pungency. Late plantings may bolt before edible root forms. About 3 to 6 weeks before average last frost, seed directly in garden ½ inch deep, 1 inch apart, in rows 12 inches apart. Thin to about 2-inch spacings. Crowded plants may not produce high-quality roots. Thinned plants can be used in salads.
For continuous harvest, make additional plantings every 1 to 2 weeks until temperatures average in the mid 60s F, or plant varieties with different maturity dates in a single planting. Resume planting when weather cools in fall.
Plant most winter varieties so that they mature around the first fall frost date. (Frost improves flavor and texture of most winter varieties.) Larger winter varieties need more space than spring varieties, so thin to about 6-inch spacings, depending on variety.
Keep soil moist for uninterrupted growth and best quality.
Adding nitrogen fertilizer or nitrogen rich manure close to planting may produce lush tops and small roots.
Can be sown in the same row with carrots, parsley, parsnips and other slow germinating crops. The radishes help to break soil crust for the weaker and later-germinating crops.
Because they mature quickly, radishes make a good intercrop along with slower growing crops, such as other cabbage family crops, or tomato- or squash family crops. Or follow radish harvest with summer succession crops such as beans, or fall-harvested crops.
