  • Sowing takes place by broadcasting immediately afterwards, abundant irrigation must be carried out: germination usually takes place within a week
  • When the seedlings have reached 10-12 cm in height, it is advisable to thin the plants leaving only the most beautiful ones at a distance of about 15 cm from each other
  • Usually the onions should be harvested when the leaves begin to dry: they should then be left to dry in a dark and airy environment, to avoid root rot.
