Growing Tips, Tricks and FAQs
Growing Tips
The Round Black Spanish radish grows best in well-draining, fertile soil with a slightly acidic to neutral pH (6.0-7.0). This radish prefers cool weather, making it ideal for spring and fall planting. Ensure the soil is loose and free from rocks to allow the roots to develop properly. Consistent moisture is essential to maintain the radish's crisp texture and prevent it from becoming woody.
When to Grow
Round Black Spanish radishes are best planted in late summer for harvest after the weather begins to cool. The best temperature for optimal growth is 50-75 F. Growing them in cool weather helps maintain their sharp flavor and crisp texture, making them a great addition to your garden's cool-weather crops.
How to Sow and Plant
To plant Round Black Spanish radishes, sow seeds about 1/4 inch deep and 4 inches apart in rows spaced 12 inches apart to give the roots enough room for growth. Succession plant for a continuous harvest.
How to Grow
Water regularly to keep the soil evenly moist, ensuring the roots develop properly. Avoid waterlogging, which can cause root rot. Keep the planting area free of weeds to reduce competition for nutrients. A light mulch can help retain soil moisture and regulate temperature, creating an optimal growing environment. Generally, no additional fertilization is needed if the soil is rich in organic matter. However, incorporating compost before planting can improve soil fertility.
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
How long does it take for Round Black Spanish radishes to mature?
This variety typically matures in about 50 days, making it slower to develop compared to other radish varieties. The longer maturity time allows the roots to develop their characteristic size and flavor.
Can Round Black Spanish radishes be grown in containers?
Yes, they can. Use a container that is at least 12 inches deep to accommodate the large roots. Ensure the container has good drainage and is placed in a sunny location.
How should I store Round Black Spanish radishes after harvesting?
These radishes store well and can be kept in a cool, dark place for several weeks. Proper storage allows you to enjoy their flavor throughout the winter months. Remove the greens before storing to prolong their shelf life.
