Sowing:  Sow in late winter to early spring on the surface of moist, good quality seed compost.  Do not cover the seed. Place in a propagator or seal in a polythene bag and maintain a temperature of 18-24C.  Germination should occur in 10-21 days. 

Growing: When the seedlings have emerged, gradually increase the ventilation by opening the propagator vents or the bag.  When large enough to handle, pot up into small pots (7-9cm) and grow on in cooler conditions in plenty of light but shaded from direct sunlight.  When the plants are large enough, gradually acclimatise to outdoor conditions before planting out in spring, 25cms apart in a sunny spot.
