Onions are best grown in the same bed for several years
to increase fertility. Dig soil deeply with compost or
manure incorporated in the autumn. Rake down and firm to
a fine level bed prior to sowing. Can be sown indoors or
in the greenhouse in February. Under cloches in March.
Outside in April when soil is warm. Seeds may be sown
direct in rows 12" apart in drills. In cold areas plant
onion sets (small dry bulbs) in April, push into soil so
that the top of the onion is exposed. Fresh manure will
produce thick necked bulbs. In August when stems yellow,
bend tops over into the centre of the row to speed up
ripening. Cloches also speeds up ripening. In late
August lift bulbs to a dry, sunny. airy place to
complete drying process.
