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, 8-15 mm (1/4-1/2″) deep and 15 mm (1/2″) apart in rows 30 cm (12″) apart. Thin to 5 cm (2″) apart for cooking onions, and 7.5 cm (3″) apart for the sweet Spanish types. Onions do best in a sunny site with fertile, well drained soil. For best quality, keep onions evenly watered throughout the entire growing season. Bend over any flower stalks that start to grow so the plant’s energy goes into building the bulb. One packet sows approximately 6 m (20’) of row.
