This splendid variety is well named, as we predict a bright future for it on the showbench - while its mild flavour and crisp texture mean it will also be in demand in the kitchen.

The golden-skinned, well-shaped bulbs, round in shape with a pointed top can reach 6in across when well grown, and are most attractive with a mild flavour.

FAQs

What month should I start sowing Exhibition Onion Seeds?

The best time to start sowing Exhibition onion seeds is indoors from December to early February. Sow the seeds in trays filled with a fine seed compost, cover lightly, and keep them in a warm spot (around 18–21°C) for germination. Once seedlings have two true leaves, transplant them into pots and harden off before planting outside after the last frost.

How can I prevent bolting and encourage large, healthy bulbs from my Exhibition onion seeds?

To prevent bolting from your onion exhibition seeds, start seeds indoors in early winter and transplant after the last frost to avoid temperature stress. Keep the soil consistently moist but not waterlogged to reduce the stress that triggers bolting. Provide good light and support seedlings as they grow to ensure strong, straight plants that develop well-formed bulbs.

How can I protect my Exhibition onion seeds and bulbs from pests and diseases?

To protect your Exhibition onion seeds and bulbs from pests and diseases, cover the plants with insect-proof mesh or fine netting to block onion flies. Remove and destroy infected plants to prevent spread, whilst mulching helps deter pests and maintain healthy soil, ensuring stronger onion growth.
