About China Rose Radish: Though China Rose is often used specifically for its delicate sprouts, in its mature form it is a type of Japanese winter radish also known as a "daikon," which simply means "large root" in Japanese. Daikon radishes account for the largest percentage of any cultivated vegetable in Japan, and can be found in some form in nearly every meal of that country.
China Rose Radish Germination: Since China Rose are winter radishes, they should be planted about two months before the first expected fall frost. Plant them in very rich, deeply worked up soil about 1/2" deep and 1" apart; later, thin the seedlings 4-6" apart.
Growing China Rose Radish Seeds: Radishes do well with consistently moist soil and the addition of organic matter such as compost. Do not allow the soil to dry out, but also avoid overwatering as this can cause splitting.
Harvesting China Rose Radish: These radish sprouts are ready to harvest after 3-5 days. The mature form of China Rose can be harvested at any time, but will be most tender at a small size; they store well for the winter.
Saving China Rose Radish Seeds: Radishes will cross pollinate with all other varieties of radish, and must be isolated by at least half a mile from other varieties to protect genetic purity. Allow the radish plant to fully mature and send up a flowering stalk; the pods will form and turn from green to brown. Pick the brown pods and allow them to dry for several days. Thresh out the seeds by opening the pods by hand, or by applying pressure to crush them. Store the seeds in a cool, dry place for up to five years.
