Sowing Instructions – Sow outdoors, April-July, in a seed bed, 0.5cm (¼”) deep, directly into finely-prepared, well-drained soil, which has already been watered. Seedlings appear in 14-28 days. Thin seedlings to 5cm (2″) apart, when large enough to handle. Plant out to flowering position in autumn, allowing 30cm (1′) between plants. Or sow indoors in April, 0.5cm (¼”) deep, in a tray of compost. Water well and place in a cold frame or unheated greenhouse. Keep moist. Transplant individually, when large enough to handle, to 7.5cm (3″) pots. Always hold seedlings by a leaf and never by the stem. Gradually accustom young plants to outside conditions, before planting out, September-October, 30cm (1′) apart. Flowers: May-July, the following year.
Hints and Tips – To encourage branching and flower production, pinch back the young plants
