How Long to Keep / Best Way to Store Leeks — Fresh, Raw | StillTasty.com - Your Ultimate Shelf Life Guide:
Leek culture
-Sow leeks indoors in late winter for fall harvest. Start more leeks in August for spring harvest.
-Grow them in soil that has plenty of compost and nitrogen.
-Don’t let leeks lack for water.
-Once leeks start growing, hill them up every 2 weeks to get more of the white part.
Watering well is important. I soak my beds twice a week. Leeks that suffer from lack of moisture grow unevenly, and have a stronger taste and pithier texture.
