Onions can be easily grown from ‘sets’ or seed. If you have ambitions to show you
can improve your chances of getting a prize by growing a good number of onions so
that you can choose a good collection to show.
So-called Japanese onions are planted in autumn and over winter growing away quickly
in spring to mature in early summer. Varieties such as Senshyu produce nice yellowish
onions ready for a show in July. These do not store as long and are best used before
Planting onion sets (small specially prepared onions) in early spring will produce
good sized onions that can be harvested from July onwards. These usually store well.
Common varieties such as Sturon will produce nice onions.
Setting seed in January or February on in a greenhouse will produce large onions
from July onwards. A very wide variety of types can be grown this way. The storing
properties depend on the variety.
These can be bought from suppliers. These are often specialist varieties for show
and are usually of the larger kind.
For showing pick a set of onions (often 3+) which are very close to each other in
size and shape. Their colour should be golden brown with unblemished skin and a
thin neck. Early shows are less fussy about colour as they often have not had time
to colour up.
