About French Breakfast Radish: Though the exact origin of French Breakfast radishes is unknown, renowned seed expert James J. H. Gregory of Marblehead, Massachusetts first offered them for sale in his seed catalog in 1875.
French Breakfast 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 French Breakfast 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 French Breakfast Radish: French Breakfast radishes taste best when harvested at a length of 3". The flavor is mildly spicy and the texture crisp.
Saving French Breakfast 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.
