Description

Grow Onion Showmaster, colossal in size and sweet-flavoured, to get impressive crops of big onions. Just choose a sunny site and grow in soil that is free-draining. Grow in direct soil or in large pots to suit your needs, incorporating a good compost suitable for vegetable growing.

You can even grow this variety to super-size proportions (records have got to 2kg) if you want to present it at a local village show and raise some eyebrows.

For impressive crops we recommend you give your onion plants supplementary lighting from UV lamps. You can still get impressive onions with a sweet flavour similar to Spanish onions, even without lighting and if you are growing for the family, children will still be suitably impressed with the large size.
