WHITE ICICLE RADISH

Though the exact origin of White Icicle heirloom radishes is unknown, they have been growing in the United States since the late 19th century. A 1903 seed catalog marketed them as somewhat of a novelty, and the 1924 Portland Seed Co. Catalog says concerning the White Icicle radish, This superb radish is the finest and longest of the very early, pure white varieties… their long, slender form and pure, paper-white skin are most attractive when bunched for market.”

Sowing: Direct sow the first crop of White Icicle radish seeds in rich soil, about four weeks before the last expected spring frost. Plant them in deeply worked up soil about 1/2″ deep and 1″ apart; later, thin the seedlings 2-3″ apart or more for larger radishes. For a continuous harvest, plant a new crop every two weeks. Since most radishes do not tolerate heat well, it is best to avoid planting them in the heat of midsummer. For a fall crop and winter storage, plant about two months before the first expected fall frost.

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: White Icicle radishes can be harvested at any time up to their mature length of 5″. The flavor is strongest at a small size, and becomes more mild as the radish matures.

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 White Icicle radish seeds in a cool, dry place for up to five years.
