For greenhouse cultivation: sow from February to April.

For outdoor cultivation: sow from March to April.

Sow seeds on the surface of a good, free-draining, damp, seed sowing mix and cover with a fine sprinkling of compost or vermiculite. Place seed trays in a propagator at a constant temperature of around 15-20C (59-68F) until after germination, which takes 7-14 days. When seedlings gain 2 true leaves, transplant into individual 7.5cm (3") pots of compost and grow on at a minimum temperature of 15C (59F).
