Sow and Plant
Sow in pots under cover in cool weather. Plant out when the soil is warm. Alternatively, sow directly into weed-free ground when the soil is warm.
Our Garden Planner can produce a personalised 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.
Can be left in the ground until required and harvested right through autumn, winter and early spring.
