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 blanch
