HOW TO GROW

Sowing: 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: 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: This variety tastes best when harvested at 1-2" in diameter. Hailstone radishes are very mild and crisp, one of the best tasting radishes available.

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.

Also know as White Globe, Hailstone's roots are pure-white inside and out. The firm flesh of this vegetable stays crisp some time after harvest! Strong dark-green medium-sized tops are larger than most globe types. Matures in 23 to 30 days.
Though no one knows the exact origin of Hailstone radishes, they are featured in seed catalogs at least as far back as 1908, when they appeared in the McKenzie Catalogue of that year.
