Sowing & growing

Sow under cover March to May in moist compost 3mm deep, then cover with a fine layer of vermiculite or compost. Keep warm during germination. Prick out into individual pots when large enough to handle. Plant out once the risk of frost has passed 30cm apart. Can also be sown directly where they are to flower June-July

Aftercare

For a bushy plant pinch out tips and deadhead to prolong flowering.
