Planting Guide
We recommend planting onions, such as Centurion, between March and April into soil 3cm deep and 12cm apart in a line. Leave at least 30cm between lines to allow growing space. Check the crop after a few days and re-plant any onions that have been disturbed by birds.
Add a general fertiliser during the growing season and ensure the crop is watered well throughout.
In late summer or early autumn, the leaves will turn yellow and die back ready for harvest. First bend the leaves to one side, lift the plant to the surface and allow to ripen on top. Once dry, remove loose skins and roots and store in a cool, dry place.
