Cultivation Tips for Growing Giant Onions

• Sowing Time: Start seeds early, typically from late December to late February, in a heated propagator or greenhouse 🌱.

• Germination: Takes about two weeks at 12°C (54°F). After germination, transfer seedlings to individual pots using a good compost mix (e.g., John Innes).

• Transplanting: Harden off the young plants by gradually acclimatizing them to outdoor conditions in a cold frame from mid-to-late March. Plant them outdoors in their final position from mid-April to late April.

• Soil and Location: Choose a hot, sunny position with excellent drainage. Enrich the soil with well-rotted farmyard manure, organic materials, and potash for optimal growth.

• Watering & Feeding: Ensure the onions are consistently watered throughout the growing season to encourage large bulb development 💧.

• Spacing: Leave 4-6 inches between plants to allow each onion bulb enough room to swell without crowding.

• Protection: Use cloches in the early stages to protect the onions. Growing under lights indoors after germination will help prevent legginess.

Culinary Uses

• Raw: Excellent in salads, sandwiches, or as a garnish.

• Cooked: Ideal for soups, roasted dishes, and stews thanks to its sweet and mild flavor.

• Preservation: Can be pickled or used in onion preserves to enjoy the sweet flavor all year round.
