|When to sow
|Sow indoors September to April.
|Where to sow
|To improve chances of germination place seeds in a polythene bag and pop in the fridge at 4°C for 3 weeks prior to sowing.
Sow indoors thinly on the surface of compost filled pots or trays and cover the seeds with a very fine sprinkling of compost or vermiculite.
Place in a warm position (15 to 18°C) and keep out of direct sunlight to exclude light until germination has occurred. Germination usually takes place within 14-21 days but can take longer.
|What to do Next
|When seedlings are large enough to handle and all risk of frost has passed, acclimatise seedlings to outdoor conditions over 7 to 10 days. Then transplant into final growing position planting them 40cm (16in) apart.
|Water well until plants are established.
|As flower stalks grow taller they may need staking.
|To encourage further blooms deadhead by cutting spent flower spikes back to small flowering side shoots.
June - September.
Autumn sowings will flower earlier the following spring.
|Ensure young plants are protected from slugs and snails.
|Cut down all growth to ground level once it has withered in autumn.
|Back of beds and borders. Make excellent cut flowers.
