LARGE AMERICAN FLAG LEEK (Heirloom, 130 days)

Heirloom 1870
Long, broad necks are blanched by gradually hilling up adjacent soil. Essential to the gourmet’s kitchen. The standard variety for many years and still one of the best if you have a long enough growing season. Also known as Giant Musselburgh. 

200 seeds


Germination- 5-10 days

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 1/4” deep early spring. Thin to 2-6” apart.

Harvest- Start harvesting baby leeks at 1/2” diameter and leave some for a larger end of season harvest.

Tips- Plant into fertile soil with lots of organic matter and adequate water for optimum growth. You can plant leeks in a trench and as the plants mature, fill in around them to assist in blanching.
