Easy to grow and ready to harvest in just 3 to 6 weeks. Make plantings of cool-season spring radishes every week or two for a continuous harvest until hot weather hits. Don’t forget winter varieties that produce large, fall-harvested roots.

Growing Guide
GROWING NOTES
Yields best in full sun.

Prefers well-drained, loose soil, high in organic matter, free from stones, with pH 5.8 to 6.8. Needs plentiful, consistent moisture.

A few winter radish varieties are biennials.

MAINTAINING
Grows 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, direct seed 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. Use thinings 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.

To help reduce disease, do not plant radishes or other cole crops in the same location more than once every three or four years.
