Plant onions between mid-March and mid-April – or in autumn. There are different cultivars for each growing season.
Plant into well worked soil.
Plant 4-5 inches apart and allow 12 inches (30 cm) between roses.
When mature, allow the foliage to yellow and flop over naturally and then 2-3 weeks later use a fork to gently ease each bulb out of the ground.
Lay out the bulbs to dry off naturally.
Once dried, they can be tied from a wire and hung above ground to dry, or be laid out on a pallet or somesuch, but make sure it can be moved or covered quickly if it rains. Once dry onions can be stored in trays filled loosely with dry hay. They can also be plaited.
It is best to rotate the location of an onion bed every one or two years to avoid disease building up in the ground.
