The first commercial variety of sweet and mild bulb onions available to UK gardeners!
So sweet and juicy they can be eaten raw
This product is produced and supplied in association with Thompson & Morgan
The first commercial variety of sweet and mild bulb onions available to UK gardeners! The large semi-globe, copper-skinned bulbs of Onion Supasweet™ are so sweet and juicy they can be eaten raw without being overpowering - ideal for adding to summer salads. Bulbs are best used as required, as they are not renowned for their storage capabilities.
Please note: Onion flavour (its sweetness and mildness) is significantly affected by weather conditions, soil type and its sulphur content. Light, sandy soils produce the highest levels of sweetness, whereas clay and dark humus rich soils can result in bulbs with a stronger flavour. Height: 45cm (18"). Spread: 10cm (4").

Direct sow onions outdoors in spring on any firm, well drained soil in full sun. Sow thinly at a depth of 1cm (1/2") and a distance of 30cm (12") between rows. Prepare the planting area several weeks in advance by incorporating some well rotted garden compost to improve drainage and soil fertility. Avoid planting onions on freshly manured soil. On particularly wet ground, try growing onions in raised beds. When large enough to handle, thin onion seedlings to 10cm (4") apart for medium sized bulbs, or at a slightly wider spacing if larger bulbs are required.
Alternatively sow onion seed indoors in module trays at a depth of 1cm (1/2"), using free-draining, seed sowing compost. Place in a propagator or seal container inside a plastic bag at a temperature of 10-15C (50-59F) until after germination which usually takes 10-14 days. Once germinated, grow onions on in cool conditions until all risk of frost has passed and they are large enough to plant outdoors at a distance of 10cm (4") apart. Cover with a protective netting or fleece to prevent attack from birds and insects. Water the plants thoroughly after planting.
