Onions
Onions need a sunny, sheltered site in well-drained soil. Avoid planting on freshly-manured ground as this can lead to rotting
Onions are best suited for growing in the open ground, but you could grow a short row or two in large, deep containers or raised beds. They are not suitable for growbags Plant onion sets 10cm (4in) apart in rows 30cm (12in) apart from mid-March to mid-April. Gently push the sets into soft, well-worked soil so that the tip is just showing, and firm the soil around them.
