When to sow March to May
Where to sow Seeds will germinate quicker if they are given a period of cold before planting. Place the seeds with a little moistened compost in a plastic bag and place in the fridge for two weeks
Sow indoors finely on the surface of moist compost filled pots or trays and cover the seeds with a very fine sprinkling of compost or vermiculite.
Cover the container with dark paper or similar as the seeds need the dark to germinate. 
Place the container in a dark place in a warm position (temperature of  18-25°C (65-77°F) is ideal). 
Remove the cover once they begin to germinate to allow air to circulate (otherwise they may suffer from damping off) and reduce the temperature to around 15°C (60°F). 
What to do Next When seedlings are large enough to handle, transplant into 7.5cm (3in) pots or trays and grow on in cooler conditions.
When all risk of frost has passed, acclimatise indoor raised seedlings to outdoor conditions over 7 to 10 days. Then transplant into final growing position planting them 30cm (12in) apart. 
  Water well until plants are established.
  Deadhead to encourage further flowering.
