Growing Guide

When to Grow

Early Scarlet Globe radishes are cool-season crops, meaning they thrive in cooler temperatures. You can start sowing seeds outdoors as soon as the soil can be worked in early spring, about 4 weeks before the last frost date. 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

Direct sow Early Scarlet Globe radish seeds 1/4 inch deep and 2 inches apart. This variety matures quickly, typically within 22 days, making it ideal for planting in several small successions for a continuous harvest.

How to Grow

Ensure the radishes receive consistent moisture throughout their growing period, about 1 inch of water per week, to maintain soil moisture and encourage even root growth. Mulching can help retain moisture and suppress weeds. Radishes do not require heavy fertilization; however, avoid high nitrogen levels, as this can encourage leafy growth at the expense of root development. Use moderate potassium and phosphorus to promote healthy root formation.

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.

FAQ
