About Lady Slipper Radish: Radishes, in their early forms, come from the ancient civilizations of China, Greece, and Egypt; soon, surrounding nations also cultivated this vegetable. While the Oriental nations cultivated the large, elongated radishes, most of the more delicate varieties such as Lady Slipper were developed by the Dutch and the French.
Lady Slipper Radish Germination: Direct sow the first crop of radishes 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 Lady Slipper 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 Lady Slipper Radish: Lady Slipper radishes can be harvested at any time up to their mature length of 4". They taste mild and crisp, and store well in the refrigerator for up to a month.
Saving Lady Slipper 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.
