  • Species and varieties: Giant red onions belong to the species Allium cepa. They are known for their large size and deep red color. Popular varieties include 'Red Zeppelin', 'Red Baron', and 'Red Burgundy'.
  • Hybrid or heirloom: Giant red onion seeds can be found in both hybrid and heirloom varieties. Hybrid varieties are often bred for disease resistance and uniformity, while heirloom varieties are valued for their rich flavor and historical significance.
  • Pruning and training: Onions do not require pruning or training. 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 red onions benefit from a balanced fertilizer applied at planting time. A nitrogen-rich fertilizer can be used during the early growth stages to promote leafy growth. As the bulbs begin to form, switch to a fertilizer with lower nitrogen and higher phosphorus and potassium levels to encourage bulb development.
  • Hardiness zones: Giant red onions can be grown in USDA hardiness zones 3-9. They are quite adaptable and can thrive in a range of climates.
  • Climate requirements: Giant red onions prefer a cool climate with temperatures between 55-75°F (13-24°C). They require full sun and well-drained soil with a pH between 6.0 and 7.0. Consistent moisture is important, especially during the bulb formation stage.
