WHERE TO SOW
September sowings in flowering site 2cm (3.4") deep. Later sowings in pots, 5 seeds in each. January sowings in a heated glasshouse. March sowings in a cold frame. April sowings direct to flowering site.
WHAT TO DO NEXT
Glasshouse raised seedlings should be hardened off during March. Plant out pot grown seedlings in the flowering site 15cm (6") apart in April. Thin direct sown seedlings to 10cm (4") apart. Pinch out growing tips after 3 pairs of leaves to encourage new growth of side shoots for more flowers.
Late June to September
