- Species and varieties: Yellow carrots (Daucus carota subsp. sativus) are a variety of the common carrot. They come in several varieties, including 'Yellowstone', 'Solar Yellow', and 'Yellow Sun'. These varieties are known for their vibrant yellow color and sweet, mild flavor.
- Hybrid or heirloom: Yellow carrot seeds can be found in both hybrid and heirloom varieties. Heirloom varieties like 'Yellowstone' are open-pollinated and have been passed down through generations, while hybrid varieties are bred for specific traits such as disease resistance and uniformity.
- Pruning and training: Carrots do not require pruning or training. However, thinning the seedlings to about 2-3 inches apart is essential to ensure proper root development and prevent overcrowding.
- Fertilization needs: Yellow carrots benefit from a balanced fertilizer applied before planting. A fertilizer with a higher phosphorus content (such as 5-10-10) is ideal for root development. Avoid excessive nitrogen, as it can lead to lush foliage but poor root growth. Side-dressing with compost or a balanced fertilizer during the growing season can also be beneficial.
- Hardiness zones: Yellow carrots can be grown in USDA hardiness zones 3-10. They are quite adaptable and can be grown in a wide range of climates.
- Climate requirements: Yellow carrots prefer cool to moderate temperatures. They grow best in temperatures between 55°F and 75°F (13°C to 24°C). They require full sun to partial shade and well-drained, loose soil to develop properly.
