HEIRLOOM 1887 British. This fine large onion has gained a considerable 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. Long day. 150 seeds.
Indoors- 8-10 weeks before last frost with soil temperatures 60-75 degrees. Plant 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 should be about a pencil thick in size at planting time.
Outdoors- Sow lightly, 1/4” deep early spring. Thin to 2-6” apart.
Harvest- Stop watering a week before harvesting. Pull out when tops fall over and skin develops. Cure them by drying them until the neck is dry, out of direct sunlight, in a warm area, and in single layer so air can circulate around them.
Tips- Plant into fertile soil with lots of organic matter and adequate water,1” per week for optimum growth.
