Site, Soil and Preparation
Leeks do best in an open position on rich, well-worked soil into which plenty of well-rotted organic matter has been added. They have a high nitrogen requirement.
Leeks are best sown outdoors in a prepared seed bed.
Sow thinly in pre-watered, shallow, short rows, lightly covering the seeds with soil.
Thin plants during transplantation to final growing position.
Plant to final position when plants are about 150mm (6in) high. Allow 200mm (8in) between plants and 450mm (18in) between rows. Make holes with a dibber about 150mm (6in) deep, and drop a plant into each hole. Fill each hole with water, but not with soil.
To ensure a long white shaft, draw up soil round the plants as they develop.
