Tips

Cover seeds lightly; provide high humidity during germination; surface sow in sunny position; keep compost moist; seedlings ready for planting at 25-30 cm height after 3-4 months; seeds have long viability; germination fastest at warmer temperatures (7-10 days at 24-27°C vs 14-21 days at 18-24°C)
