Description

(Raphanus sativus). An early, old-time, white spring radish, this one is superb! Simply the best-tasting radish we have tried, and many of our customers agree. Very mild and crisp.

Growing Tips: White Hailstone radishes grow best in cool weather and should be planted in well-drained, fertile soil. Regular watering is important to maintain moisture and prevent the roots from becoming too spicy or woody. Make sure that they receive full sun to partial shade.

When to Grow

Plant White Hailstone radishes in early spring. They prefer cooler temperatures, typically between 50 F and 75 F. Succession plant every couple of weeks for a continuous harvest. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

Sow the seeds directly in the garden about 1/4 inch deep and 2 inches apart. Space rows about 8-12 inches apart to avoid overcrowding and give roots enough space to develop.​

How to Grow

Maintain consistent moisture to keep the soil evenly moist but not waterlogged. Mulching can help regulate soil temperature and moisture levels. White Hailstone radishes mature quickly, typically within 23 days, so monitor them closely to harvest at the right time for optimal flavor and texture​.

How to Save Seeds

  • Radishes are insect-pollinated, so you'll need to isolate varieties by up to 1⁄2 mile or stagger plantings to avoid flowering at the same time.
  • Staggering can be easy because of the radish's quick maturity.
  • Allow flower stalks to shoot up and seed pods to dry on the plant before picking pods and opening by hand to remove the seeds.
  • Seeds will remain viable for up to 5 years when stored in an airtight container.
