Sowing method: Sowing time is all year round. The seeds germinate erratically over a longer germination period. Therefore, do not discard the seedlings too soon. First sow in a seed tray: 3 weeks at 20°C. Then 3 weeks in the refrigerator. Repeat this process until enough seedlings have germinated. If seeds germinate in the period October-March, keep them indoors after emergence, in a light and cool place (minimum 10°C). Prick out into pots.
