Sowing & growing

Sow inside either October to December and overwinter in a cool but light space or in January to April. In late Spring you can also sow directly outside. Always sow 2-3 seeds together and pinch out the top once 2nd pair of leaves appear.

Aftercare

Tie in regularly to supports and cut flowers continually. Deadhead regularly to prevent seed pods developing. Feed with a high-potash fertiliser.
