Notes
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.
|
Harvesting
Can be left in the ground until required and harvested right through autumn, winter and early spring.
