Sowing: depending on the variety, planted or in seedbeds. Transplant: keep the collar level with the ground, not buried, at a distance of 35-45 cm between the rows and 25-35 cm on the row. Advice: pick the head just before complete ripeness: it will be sweeter. Seeds required: in seedbeds 2 g per m2, planted 20-30 g per 100 m2.
