Ailsa Craig produces very large, round onions, often up to 1–1.5 kg. The taste of this onion is mild to nice and slightly sweet. These onions can also be stored reasonably well. Sow thinly directly in the garden in rows and cover the seed well. Keep the soil moist constantly. After emergence, do not thin out too much. Harvest the onions once the foliage has died off. Allow the onions and foliage to dry on the field for 1 week.
