Sweet Spanish Utah Onion Seeds (Large Globe Type) 1860. Our best large onion – globular in shape with a mild, sweet taste. The flesh is firm, clear and tender. Under ideal conditions, these onions will weigh over 1 kg (2.2 lbs) at harvest. Irrigation is often needed to maintain full bulb development. Light cultivation between rows through the season is essential to reduce competition from weeds.
How to Grow
280 seed/gram. 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 (3″) 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. 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.
