How to Grow

Seed can be started indoors in a soil-less growing medium in February. The seedlings can then be transplanted outside later in spring. Seed can also be sown directly outdoors from mid April, 8-15mm (1/4-1/2in) deep and 15mm (1/2in) apart in rows 30cm (12in) apart. Thin to 5cm (3in) apart for cooking onions, and 7.5cm (3in) apart for the sweet Spanish types. Onions do best in a sunny site with fertile, well drained soil. Bend over any flower stalks that start to grow so the plant’s energy goes into building the bulb.
