  • Species and varieties: Giant onion seeds typically refer to varieties of Allium cepa, known for producing large bulbs. Popular varieties include 'Ailsa Craig', 'Kelsae', and 'Exhibition'. These varieties are known for their impressive size and are often grown for competitions.
  • Hybrid or heirloom: Giant onion seeds can be both hybrid and heirloom. For example, 'Ailsa Craig' is an heirloom variety known for its large size and mild flavor, while some other giant onion seeds may be hybrids developed for specific traits such as disease resistance and uniformity.
  • Pruning and training: Giant onions do not require pruning. However, it is important to keep the area weed-free to reduce competition for nutrients and water. Mulching can help retain soil moisture and suppress weeds.
  • Fertilization needs: Giant onions are heavy feeders and benefit from a well-balanced fertilizer. A high-phosphorus fertilizer can be applied at planting to promote root development. During the growing season, a nitrogen-rich fertilizer can be used to support foliage growth. Regular feeding every 2-3 weeks is recommended.
  • Hardiness zones: Giant onions can be grown in USDA hardiness zones 3-9. They are quite adaptable but perform best in cooler climates.
  • Climate requirements: Giant onions require a long growing season with cool temperatures. They thrive in full sun and well-drained soil. Consistent moisture is crucial, especially during the bulb formation stage. They prefer temperatures between 55-75°F (13-24°C).
