Growing Tips
Giant of Sicily radish grows best in well-drained, fertile soil with full sun exposure. Maintain even moisture levels to avoid the radishes becoming woody or splitting. Radishes grow best when they have cool, consistent conditions. Sow spring radishes in several small successions for a continuous harvest.
When to Grow
Plant Giant of Sicily radishes starting 4 weeks before the last frost date for best results, as they prefer cooler weather. The optimal temperature for growth is between 50-75 F. In hot climates, consider fall planting to avoid bolting, which happens when radishes are exposed to high temperatures and long days.
How to Sow and Plant
Sow seeds directly in the garden bed in the spring. The seeds should be sown about 1/4 inch deep and spaced about 2 inches apart, with rows spaced 8-12 inches apart. You can continue succession planting every 2 weeks.
How to Grow
Keep the soil consistently moist but not waterlogged, and avoid letting it dry out completely. Radishes do not tolerate drought well, as irregular watering can cause them to split. Use mulch to retain moisture and suppress weeds. Make sure to thin out the plants early to avoid overcrowding, which can lead to poor bulb formation. Regularly check for pests like flea beetles and root maggots, which can damage the leaves and roots.
How to Save
- 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
Can Giant of Sicily radishes be grown in containers?
Yes, as long as the container is deep enough for the roots to develop properly. Use a well-draining potting mix and ensure consistent moisture.
What are common issues to avoid when growing radishes?
Overcrowding, inconsistent watering, and planting in hot weather can lead to poor bulb formation and bolting. Flea beetles and root maggots are common pests.
How do you know when radishes are ready to harvest?
Radishes are ready to harvest when they reach about 1-2 inches in diameter. Leaving them in the ground too long can cause them to become woody. Giant of Sicily matures in about 35 days (30-45 days, depending on growing conditions).
