      Sowing

      Sow once the soil is warmer than 10 °C, in a sunny spot sheltered from the wind. Sow about three times as deep as the seed is thick, into finely raked soil with no clods on top. Spacing is as printed on the packet — thin the seedlings out after they come up. Water with a fine spray so the seed is not washed away, and keep only the strongest plants.

      Description

      What Japanese Radish Ostergruss is

      Japanese Radish Ostergruss (Raphanus sativus var. niger) is an annual vegetable of the Cabbage family (Brassicaceae). This is an Austrian early variety.

      The flesh is fresh and crisp. Used for fresh consumption.

      Radishes are rich in ascorbic acid, folic acid and potassium.

      They are a good source of vitamin B6, riboflavin, magnesium, copper and calcium.

      One cup of sliced radishes provides approximately 20 calories.

      Winter radishes (black, white and purple radish) are sown in summer and produce large, pungent roots that keep through the winter.
