A member of the onion family. Looks rather like a large scallion or spring onion Grow in seed trays or punnets until about 20cm (8in) tall. They look rather like large blades of grass at that stage. Then plant out into trenches or individual deep holes. The aim is to blanch the stems while the plants are growing. Trenches should be about 20-25cm (8-10in) deep. Set the seedlings 10-15 cm (4 - 6in) apart then add enough soil to just cover the roots. As the plants grow fill the trench. Otherwise - make holes with a dibble or suitable stick 15 cm (6 in) deep and 3-4 cm (1.5 - 2 in) wide. Drop a seedling in each and water enough to cover the roots with soil. As they grow, watering will gradually fill the hole.

Leeks prefer moist clay soils. Keep soil moist and loose, mulch will help.

Culinary hints - cooking and eating Leeks

Trim off the roots and any damaged leaves.
Young ones can be used whole with some of the green leaves
Wash thoroughly as the earth tends to get inside.
Chop and fry in butter (or olive oil) until tender.
Can be added to casserole meals, allowing time to cook through.
Leek and mushroom make a tasty combination for a tart filling.

Leeks prefer a moist clay type soil. I suggest you keep building your soil up with heavier soil, if you can get it, and plant your leeks closer together, making the most of smaller leeks in the meantime. Maybe leaving them in the ground a bit longer will help them to thicken.
