Description

A favourite onion variety of gardeners who appreciate both impressive size and outstanding flavour. Known for producing large, tender, and sweet onions, 'Exhibition' is perfect for competitions or simply elevating your home cooking. Its mild taste and juicy texture make it versatile, whether you’re slicing it into salads, grilling, or caramelising for recipes.

This onion thrives in sunny gardens, raised beds, or allotments, making it a versatile choice for growers of all levels. Its strong disease resistance ensures healthy plants throughout the season, while its consistent growth guarantees plentiful yields.

To grow 'Exhibition' onions, plant in rich, well-drained soil in a sunny spot. Regular watering is essential, especially during dry spells, and feeding with a high-nitrogen fertiliser will encourage vigorous growth and large bulbs.

These onions pair well with companion plants like carrots, garlic, or lettuce, making them a valuable addition to any vegetable patch. Their reliable yields and exceptional flavour ensure your kitchen will be stocked with fresh, homegrown onions throughout the summer and into early autumn.

Enjoy free delivery on these plug plants! Please note: If you add other items to your order then this may include a postage surcharge.

Supplied as set of six plug plants, ready to grow on and plant out, once all risk of frost has passed.

Top Tips
  • Keep the area weed-free to reduce competition for nutrients and water. Hand-weed carefully to avoid damaging shallow onion roots.
  • Care Information
    • Plant onion plug plants outdoors from late spring to early summer after the risk of frost has passed.
    • Onions thrive in a sunny spot with at least 6 - 8 hours of direct sunlight daily.
    • Select an area with well-drained soil, preferably light, sandy, or loamy. Avoid heavy clay soils unless improved with compost or grit.
    • Work the soil to a fine texture, removing any weeds, rocks, or debris. Enrich the soil with organic compost or a balanced fertiliser, ensuring it is rich in nitrogen for healthy development.
    • Plant each plug 10 - 15cm apart in rows spaced 30cm apart.
    • Ensure the roots sit just below the surface level, with the neck of the plant slightly exposed.
    • Gently firm the soil around the plug to eliminate air pockets, and water well after planting.
    • If growing in pots, use a deep container with good drainage holes. Fill with multi-purpose compost mixed with grit for drainage.

    Caring:

    • Keep the soil consistently moist but not waterlogged. Reduce watering as the bulbs mature to prevent rotting.
    • Feed with a high-potash fertiliser every 3 - 4 weeks to encourage bulb formation. Avoid over-fertilising with nitrogen late in the growing season.
    • Apply a thin layer of mulch to retain moisture and suppress weeds, but keep it away from the neck of the plants to prevent rot.

    Harvesting:

    • Harvest onions when the tops turn yellow and begin to flop over, usually 90 - 120 days after planting.
    • Gently lift the bulbs using a garden fork or trowel, taking care not to damage them.
    • Lay onions out in a dry, airy space to cure for 2 - 3 weeks. Once the outer skins are papery and dry, trim the tops and roots.
    • Store cured onions in a cool, dark, and dry place. They can last for several months if kept in ideal conditions.
