Using a good quality, moist seed compost, sow your seeds in a propagator and cover with 6mm (¼") compost. Place on a windowsill or in a greenhouse at approximately 21-24°C (70-75°F) to germinate, usually 7-14 days. Transfer seedlings into 7.5cm (3") pots and grow on. Once they are 15cm (6") tall, transfer to 25cm (10") pots of John Innes No.3 and keep on a warm, sunny windowsill or greenhouse (once warm enough). Pollinate with a small paintbrush by stroking all the flowers, if no insects present. This will ensure fruit.
