SOW SPRING ONIONS IN POTS

Try ‘White Lisbon’, a fast-growing spring onion, ready for harvest just eight weeks after sowing, or ‘Apache’, with bright purple-red skin and a crispy texture, as both are ideal to sow in a container. You’ll just need a pot, trough or windowbox, and multi-purpose compost mixed with garden compost or slow-release fertiliser. Fill pots up to about 2.5cm (1in) off the rim with moist compost and firm in gently. Then sprinkle the seed and cover it with a thin layer of soil. Sow direct in your trough or start off in smaller pots to prick out and grow on.
