Sowing & Propagation
For exhibition-sized onions, sow from late November through January under glass or in a heated propagator at 18 to 20°C. Sow seeds approximately 5 to 10 mm deep into a quality seed compost.
Once seedlings have developed, pot them on individually into larger containers to encourage strong root development. Maintain good light levels throughout winter and harden plants off before planting outdoors after the danger of severe frost has passed.
Growing On
Grow in deep, fertile, moisture-retentive soil enriched with generous quantities of well-rotted manure or compost. Choose a sunny, sheltered position with excellent drainage.
Water regularly throughout the growing season to maintain uninterrupted growth and apply a balanced fertiliser before changing to a high-potash feed as bulbs begin to swell. Keep the crop free from weeds and avoid any checks in growth, particularly during the early stages of bulb development. Exhibition growers often grow under protection to achieve perfectly clean bulbs with outstanding skin quality.
Harvesting
Harvest from late August to September, once the foliage naturally yellows and bends over. Lift bulbs carefully and allow them to cure in a warm, airy, frost-free location until the necks are completely dry.
Once cured, the onions store well in a cool, dry place and retain their attractive appearance for many weeks. Exhibition bulbs should be handled carefully to preserve their shape and skin finish.
