Description Sowing More Info Delivery
This perennial oriental bunching onion doesn't produce bulbs but forms clumps of elongated, straight white stems similar spring onions. Alternatively the stems can be earthed up to produce leek-like stems. Onion 'Ishikura' can be harvested when pencil-thin or left to grow as thick as a mature carrot. This RHS AGM variety has a remarkably long harvest period from June to October without the need for successive sowings. Height: 30cm (12"). Spread: 23cm (9").


Companion planting: Try growing onions with mint to confuse and deter onion fly.

Sowing Months Harvest Months
Welsh onions are undemanding and require only occasional watering during particularly dry periods. However, rows should be weeded regularly. Harvest individual leaves as and when required or pull up part of the clump for the small leek-like stems. Welsh onions should be used immediately as they do not store well once harvested.

Direct sow onions outdoors in spring on any firm, well drained soil in full sun. Sow thinly at a depth of 1cm (1/2") and a distance of 30cm (12") between rows. 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 onions in raised beds. When large enough to handle, thin welsh onion seedlings to 23cm (9") apart for medium sized bulbs, or at a slightly wider spacing if larger bulbs are required.

Alternatively sow onion seed indoors in module trays at a depth of 1cm (1/2"), using free-draining, seed sowing compost. Place in a propagator or seal container inside a plastic bag at a temperature of 10-15C (50-59F) until after germination which usually takes 10-14 days. Once germinated, grow onions on in cool conditions until all risk of frost has passed and they are large enough to plant outdoors at a distance of 23cm (9") apart. Cover with a protective netting or fleece to prevent attack from birds and insects. Water the plants thoroughly after planting.
