A flattened oval onion, which is suitable for long storage. Red onions have a sharper taste than the yellow ones. Sow thinly directly in the garden in rows (row distance 25 cm and plant distance 15 cm), and cover the seed well. Keep the soil moist constantly. After emergence, do not thin out too much. Lightly fertilise the soil, preferably with compost. Harvest the onions once the foliage has died off. Allow the onions and foliage to dry on the field for 1 week.
