Sowing – Sow Dianthus seeds indoors from February to April on the surface of lightly firmed, moist seed compost in pots or trays and cover with a fine sprinkling of compost or vermiculite. Place in a propagator or seal container inside a polythene bag and keep at a temperature of between 18-20°C (64-68°F). After sowing, do not exclude light as this helps germination. Keep the surface of the compost moist but not waterlogged; germination usually takes 14 – 30 days.

Growing – When seedlings are large enough to handle, transplant into 7.5cm (3in) pots and grow on in cooler conditions. Gradually acclimatise to cooler conditions for a few weeks before planting out after all risk of frost. Plant at a distance of 23cm (9in) apart on any fertile, well drained soil in full sun.

Flowers – July to September
