Growing Information

Growing Ailsa Craig Exhibition Heirloom Onion

‘Ailsa Craig Exhibition’ is a Scottish heirloom onion prized for its enormous size, mild sweetness, and impressive exhibition-quality bulbs. Pale yellow skins surround mild, very sweet flesh, producing large globe-shaped onions that are equally useful in the kitchen and on the show table.

Start ‘Ailsa Craig Exhibition’ indoors for transplanting. Plant seeds about ¼ inch deep and grow in full sun. This cold-tolerant variety is also well suited to containers.

Ready to harvest in about 100 days, lift the bulbs once they have reached the desired size and maturity and the tops begin to indicate they are ready for harvest.

Mild, sweet, and impressive, ‘Ailsa Craig Exhibition’ is excellent for fresh slicing, salads, burgers, sandwiches, and storage.

I had two come up. I grow these all the time, but these were duds.

not so good

Not having much luck with these. 1 in 20 or so will germinate and then stall even with fertilizer. Started indoors and under light after sprouting then moved to three gallon grow bags.For us in North Idaho any onions are difficult. We`ll keep trying but doesn`t look promising at this time.

Ailsa Craig, a Great onion

I have planted Ailsa Craig along with other onion types. I have had the best germination success with Ailsa Craig. In addition, production with Ailsa Craig always exceeds other varieties. I have been planting this variety for at least 10 years. As for storage, I get some sprouting, but from my time of harvest in August, they store until depleted in January. I don't think 4 to 5 months storage is bad.
