- Species and varieties: Yellow potatoes belong to the species Solanum tuberosum. Popular varieties include Yukon Gold, Yellow Finn, and Carola. These varieties are known for their creamy texture and buttery flavor.
- Hybrid or heirloom: Yellow potato seeds can be both hybrid and heirloom. Yukon Gold is a well-known hybrid variety, while Yellow Finn is often considered an heirloom variety. Heirloom varieties are open-pollinated and have been passed down through generations, while hybrid varieties are bred for specific traits such as disease resistance and yield.
- Pruning and training: Potatoes do not require pruning or training. However, they do benefit from 'hilling,' which involves mounding soil around the base of the plants as they grow. This helps to protect the developing tubers from sunlight and supports the plant.
- Fertilization needs: Yellow potatoes benefit from a balanced fertilizer high in phosphorus and potassium. A common recommendation is to use a 5-10-10 fertilizer at planting time. Avoid excessive nitrogen, as it can lead to lush foliage but poor tuber development. Side-dressing with compost or a balanced fertilizer midway through the growing season can also be beneficial.
- Hardiness zones: Yellow potatoes can be grown in USDA hardiness zones 3-10. They are quite adaptable and can be grown in a variety of climates.
- Climate requirements: Yellow potatoes prefer a cool climate with temperatures ranging between 60-70°F (15-21°C). They require full sun and well-drained soil. Potatoes do not perform well in hot, humid conditions and are best planted in early spring or late summer in warmer regions.
