GERMINATION INSTRUCTIONS : Sowing Direct : Sow thinly, 3mm (1/8in) deep in drills 30cm (12in) apart in wellcultivated soil which has been raked to a fine tilth. Water ground regularly, especially in dry periods.

When large enough to handle, thin out seedlings to 15cm (6in) apart
Sowing Indoors: Sow in pots or trays of moist seed compost and cover with a very fine sprinkling of compost or vermiculite. After sowing, do not exclude light as this helps germination. Keep at 15-20°C (59-68°F). Keep the surface of the compost moist but not waterlogged. Germination will usually take 14-21 days. When they are large enough to handle, transplant the seedlings into 7cm (3in) pots or trays. Overwinter plants in cool, light, frost-free conditions before planting out the following spring, or grow on as greenhouse pot plants.
