Sow at 15-20°C (60-68°F) in pots or trays using a good quality, moist compost, cover the seed lightly with a sprinkling of compost, or vermiculite. Place in a polythene bag or propagator and keep the soil moist at all times. When the seedlings are large enough to handle transfer and grow on in cooler conditions. Acclimatise them to outdoor conditions over 5-7 days before planting out 15cm (6") apart.
