HOW TO GROW

Sowing: Since White Spear 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. This variety can also be grown for sprouting.

Growing: 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: These radish sprouts are ready to harvest after 3-5 days. The mature form of this radish can be harvested at any time, but will be most tender at a small size; they also store well for the winter.

Seed Saving: 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.
