~ Growing ~
Soil:
Black Spanish Radish prefers well-drained, loose soil rich in organic matter. Avoid compacted soils that can hinder root development.
Watering:
Keep the soil evenly moist, especially during the growing period. Avoid overwatering, as too much moisture can cause the roots to split.
Light and Temperature:
Grows best in full sun during cooler seasons. Ideal growing temperatures are between 40°F and 70°F.
Maintenance:
Thin seedlings as needed to prevent overcrowding. Radishes are low-maintenance, but regular watering and proper spacing will promote larger, healthier roots.
Container Friendly:
Can be grown in deep containers with loose, well-drained soil. Ensure the container is large enough to allow for proper root development.
~ Harvesting ~
When to Harvest:
Harvest when the roots are firm and 3-4 inches in diameter, typically 50-70 days after sowing. Overgrown radishes may become woody.
How to Harvest:
Gently pull the radishes from the soil by their green tops. If the soil is compacted, use a garden fork to loosen the earth before pulling.
Drying and Storing:
After harvesting, brush off excess soil and store in a cool, dark place. Black Spanish Radishes can be stored for several months in cold storage or a root cellar.
Edible Use:
The crisp, peppery flavor of Black Spanish Radish makes it ideal for roasting, adding to salads, or slicing thinly for a fresh crunch. The radish tops can also be used in salads or stir-fries.
~ Seed Saving ~
Seed Collection:
Allow some radishes to flower and form seed pods. Once the pods are dry and brown, collect the seeds.
Seed Cleaning:
Remove seeds from the pods and air-dry them fully before storing.
