Growing to a height of around 45cm (18in) and a spread of 15cm (6in). Overwintered onions are in the ground a lot longer than their summer counterparts – roughly 300 days. Because of this, they have more time to develop a vigorous root system, which means they grow more strongly on heavy soils. In addition, overwintering types do most of their growing during spring, when soil moisture is plentiful. They mature and dry down in early summer when the days are at their longest. All these factors add up getting larger onions with less effort.

Since these onions are ready to harvest between June and early July, the, usually dry weather we receive then is much more conducive to good curing.

  • The ideal onion to add to any meal you wish.

How to grow?.

  • Plant onion sets in rows in any firm, well drained soil in full sun.
  • Prepare the planting area several weeks in advance by incorporating some well rotted garden compost to improve drainage and soil fertility. Avoid planting onions on freshly manured soil.
  • On particularly wet ground, try growing onion sets in raised beds.
  • Plant the bulbs so that the tip of bulb is just protruding through the soil surface.
  • Leave a space of 10cm (4″) between each bulb, and 30cm (12″) between each row.

Special Note: Onion sets are simply small, immature onions, which have been lifted and dried to prevent any further growth. Once planted in spring the sets grow in size and each one forms a full-sized bulb when ready to harvest.
