Our Garden Planner can produce a personalized calendar of when to sow, plant and harvest for your area.
When leeks are almost the size you prefer, blanch them for 2 to 3 weeks by putting a mound of soil, mulch, or a cardboard tube around the base of each stem. Grows best in climates where nights remain cool through summer. In mild winter climates, try leeks as a fall-to-spring crop.
Dig as needed in the kitchen. In cold winter climates, dig plants before the ground freezes in early winter.
Struggling plants may be infested with onion root maggots, which are easy to see when you dig up a plant. Promptly remove affected plants.
