Sow seeds shallowly at only 3mm (1/8″) deep. If starting indoors, provide total darkness and a soil temperature of 21-25°C (70-75°F). Once sprouts appear, provide bright light.
Space plants at 30-38cm (12-15″) apart in any average, well drained, slightly acidic soil. Water plants regularly for best results, keeping the leaves as dry as possible. Leave seed heads intact over winter to feed birds and provide shelter for beneficial insects.
