WHEN TO SOW
January to March
Space the seeds 2cm (1/2") apart in trays or individually in modules under glass at 18°C. Cover with polythene or glass to retain humidity. Remove cover as soon as seedlings appear. Once true leaves have opened, prick off tray seedlings into 9cm (4") pots. When the first flowers are forming, transplant to growing site. Stake for support and remove side shoots as they appear.
Harden off the plants before transplanting to outdoors.
