Start off in 7.5cm (3") pots indoors and plant out in your vegetable plot. Fill pots with good, free-draining, damp, seed compost. Sow seeds 1cm (1/2") deep in the compost. Place the pots in a propagator or seal inside a polythene bag and keep at around 20-25C (68-77F) until the seeds germinate. This will take about 7-10 days. Don’t exclude light as this helps germination.
Acclimatise the plants to cooler conditions by putting them outside for a few hours a day for a few weeks. Before planting out in the garden, prepare the ground by raking until it is fine and crumbly, removing any large stones. Plant out when all risk of frost has gone, about 60cm (24") apart between each plant and between each row.
