Ailsa Craig Exhibition Onion (Heirloom, 105 Days)

Long Day
British Heirloom 1887. This fine large onion has gained a big following in the past several years. Bulbs in excess of 3 pounds are possible, but the real virtue of this variety is the quality. Color is a snow-white, centers are bull’s eye single, tops are vigorous, and the flavor is very sweet. Great for slicing raw. Every year that we grow it we reaffirm that Ailsa Craig is the biggest, the earliest, and the best.

150 seeds  

Please note that germination rates for alliums (onions/shallots/chives/leeks) decline rapidly. We strongly encourage you to purchase new seed each growing season.

PLANTING

Allium cepa

Sowing Indoors: Start 8-10 weeks before last frost with soil temperatures 60-75ºF. Sow in flats 1/4” deep, 1/4” apart. Transplant seedlings out mid/late spring, 2-6” apart. Liquid fertilize seedlings every 7-10 days. Seedlings size should be about a pencil thick at transplanting time.

Sowing OutdoorsEarly to mid-spring when soil temperature reaches at least 55 ºF. Sow 1-3 seeds per inch, thin to 2-6” apart. The larger the bulb size the more space. 

How much does a packet plant: 15-30 foot single row  

Harvest- Stop watering a week before harvesting. Pull out when necks soften and start to fall over. Cure them in the sun for a few days then finish drying them out of direct sunlight, in a warm area, and in single layer so air can circulate around them until the neck is dry. Store in a cool dark place with 35-40ºF temperatures and 65-70% humidity.

Tips- Needs fertile, well drained soil. Amend with compost or apply organic granular fertilizer. Adequate water is very important for optimum growth, 1" per week.

Ailsa Craig Onions: I grow these every year and they perform well even thought we are in So. California. If I plant in early falls I can thin for green onions in winter and harvest the bulbs around August.

I love your catalogue and the fact that I get just enough for one season. With the smaller seed packets, I can try out more varieties. I’ve found your descriptions to be reliable.

outstanding

I grow most of my onions from sets, but these are easy to germinate and it is amazing to me that they grow as large as the ones I plant feom sets. Unbeatably delicious made into crispy homemade batter fried onion rings.
