How to plant outdoors:
Germination temperature: 55 F to 85 F
Days to emergence: 3 to 7
Outdoor, or garden growing:
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.
