Neptune Leeks Winter Vegetable Seeds - 100 Organic Leek seed Bred in England, perfect for British weather conditions! Leeks are a flavoursome winter vegetable that can be steamed or boiled, braised in a cheese sauce & used in soups & stews. Leeks are easy to grow, but need looking after - you need to sow them in containers or a separate part of the garden before moving them to their final position. Sow indoors over winter for an early crop. After last frost transplant them outside. Or, sow seed direct in spring, & you will be lifting leeks from autumn to late winter. Sow thinly or sow three seeds at 15cm (6in) intervals, 13mm (0.5in) deep in rows 30cm (12in) apart. Although it is sometimes recommended to start sowing in February, this can lead to failure.
