Germinate at 18-20C (64-68F) on the surface of a good free draining, damp seed sowing mix. Apply a layer of sowing mix or vermiculite, 3mm (1/8in) deep. Place in a propagator or seal container inside a plastic bag until after germination which usually takes 5-10 days. Do not exclude light, as this helps germination. Growing Instructions Transplant seedlings, when large enough to handle into 7.5cm (3in) pots. Grow on in cooler conditions for at least 10-15 days before planting out. Plant outside after all risk of frost, 30cm (12in) apart.
