Sowing Direct :
Sow thinly, 3 mm deep in drills 30 cm apart in well-cultivated 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 15 cm apart
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-+20C. 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 7 cm pots or trays. Overwinter plants in cool, light, frost-free conditions before planting out the following spring, or grow on as greenhouse pot plants.
