This is a splendid exhibition variety of golden merit producing large globe shaped onions with a rich, golden straw coloured skin.

Onion Ailsa Craig can also be autumn sown.
Sow seeds during mid-late winter in a good seed compost, just covering the seeds with compost. Germination takes 14-21 days at 19-21C. Higher temperatures may prevent germination. Transplant seedlings when 36mm high into 9cm pots. Making sure the tiny bulb is not covered. When well rooted move to a cold frame and plant out in early spring at 38cm apart in a sunny spot in a rich fertile soil. Keep the soil moist during dry spells. As the leaves start to yellow bend over the tops, leave 14 days then lift and store when thoroughly ripened.
