An improved Japanese cultivated variety which is great for early planting and can be harvested from late May to early June. Onion 'Radar' has a mild flavour and will store well until the following spring in the right conditions. This onion also has a good resistance to bolting.


Garden care:
Plant onion sets from mid-February to March, 15cm (6in) apart in rows 30cm (12in) apart. Lift the onions when they are mature and allow them to dry before using. Store the fully ripened, sound bulbs in nets or trays and you can use them throughout the autumn and winter.
