Perfect for sowing indoors in autumn or outdoors in spring, these onions thrive in full sun and well-drained soil, reaching up to 45cm tall. Each packet provides around 80 seeds, giving you a generous supply for your home growing needs, and when planted alongside mint, you'll help deter onion fly naturally. You'll enjoy harvesting bulbs weighing up to 120g each that store well for extended kitchen use. Direct sow onions outdoors in spring on any firm, well-drained soil in full sun. Sow thinly at a depth of one centimetre and a distance of 30cm 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.
