Giant Musselburgh Leek

Giant Musselburgh Leek


105 days. One of the best winter-hardy leeks you can grow. This Scottish heirloom has provided families with hearty soups and stews since the 1830s. An old dependable leek that produces thick white stalks 2-3 inches in diameter. The mild flavor and smooth, tender stalks explain why this variety has been passed from one generation to the next. The largest leek in our trials and one of the last to bolt.

CULTURE: Leeks are a cool-season biennial grown as an annual. They are well worth the effort because they are frost hardy and can supply the gardener with fresh onions all winter and well into spring. They thrive in well composted, well worked, and well drained soil. Leeks can be started as transplants or direct sown in the garden if you have optimum soil conditions. Transplants will yield larger plants by autumn.
FOR TRANSPLANTS: Begin 8-10 weeks before your last frost. Sow up to 100 seeds in a sterile seedling mix in a 4-6 inch pot. Cover the seeds. Place in a warm location and keep moist. For stockier plants, keep the tops trimmed to 3 inches. Transplant into the garden after the threat of frost has passed, and when the soil can be worked to a depth of 8-10 inches. Dig a trench 5 inches deep and wide. Each row should be 12-18 inches apart. Work in 1/4-1/2 cup of our complete fertilizer per 5 row feet. Place seedlings in the bottom of the trench about 4-5 inches apart. Leeks do best when planted close enough to touch each other as they grow. Blanch to increase the length of white stem by gradually filling in the trench as the leeks grow.
DIRECT SEEDING: After your last frost, direct sow seeds in rows 12-18 inches apart. Cover with vermiculite or sifted compost. Thin plants.
HARVEST: Dig anytime the leeks are 1/2 inch in diameter or larger. Can be used raw or cooked. Store at 33°F and 65% relative humidity.
INSECTS/PESTS: Seldom a problem.
DISEASE: Very resistant.
SEED SPECS: Minimum germination standard: 70%. Usual seed life: 1 year. Days to maturity are calculated from date of transplant.

I love this leek. Big, survived all winter, didn't bolt, survived the chickens, survived me. Had one or two rot out this spring in our saturated clay soil.
Grows well

I'm still a novice at leeks. Planted in the spring time, and harvested at the beginning of fall. Didn't leave it long enough to see how it did in colder weather, but it didn't bolt in the summer.
