- Species and varieties: The round cherry radish, also known as Raphanus sativus, is a popular variety of radish known for its small, round, and bright red roots. This variety is often referred to as 'Cherry Belle' and is prized for its crisp texture and mild, slightly peppery flavor.
- Hybrid or heirloom: The round cherry radish is typically an heirloom variety, meaning it has been passed down through generations without genetic modification. Heirloom seeds are valued for their historical significance and genetic diversity.
- Pruning and training: Radishes do not require pruning or training. However, thinning seedlings to about 1-2 inches apart is essential to ensure proper root development and prevent overcrowding.
- Fertilization needs: Radishes are relatively low-maintenance when it comes to fertilization. They benefit from a well-balanced, all-purpose fertilizer applied at planting time. Avoid high-nitrogen fertilizers, as they can promote excessive leaf growth at the expense of root development. Compost or organic matter can also be added to the soil to improve fertility.
- Hardiness zones: Round cherry radish seeds are suitable for USDA hardiness zones 2 through 10. They are quite versatile and can be grown in a wide range of climates.
- Climate requirements: Radishes thrive in cool weather and are best planted in early spring or fall. They prefer temperatures between 50°F and 70°F (10°C to 21°C). Radishes can tolerate light frost but may bolt in hot weather.
