Days to Germination: 3-7 days
Germination Temperature: 45°-85°F
After the danger of hard frost has passed, direct sow Daikon Radish seed in moderately fertile, well draining soil in full sunlight. If necessary, amend the soil lightly with organic fertilizer, compost and/or well-rotted manure: overly rich soil may result in too much top growth and not enough Radish. They prefer sunny, cool weather. Direct-sow 1⁄4" deep in rows about 8" apart, tamp down and water lightly. The key to growing crisp, mild Daikon Radishes is to keep them well watered and thinned to 1" to 2" apart once they are 2" tall. Radish thinnings may be tossed into salads – tops and all. Harvest Daikon Radishes when they are small and tender for the mildest flavor and most crispy texture. Pull each Daikon Radish gently out of the soil. Direct-sow every 7 to 14 days for a steady supply through the summer.
