Sowing Indoors

Almost fill a seed tray with moist seed compost. Sow seeds thinly over the surface, and lightly cover them with a little more compost. Place in warmth 18-20C (65-70F), and keep moist.

Transplanting

Indoors: When first flowers have opened, transfer to growing bags, large pots or greenhouse border.

Outdoors: Gradually accustom plants to outside conditions for 2-3 weeks before planting out when danger of frost has passed. Allow 60cm (24in) between plants.

Growing on / thinning

Keep seedlings in a light position, but shade from bright sun. When large enough to handle, transplant seedlings individually to small pots of potting compost, and maintain a minimum 15C (60F).

Special note

Support the main stem of each plant with a bamboo cane. Remove side shoots as they appear. Harvest July-September in a greenhouse and August-September outdoors.
