If you are looking to purchase giant exhibition leek seeds then you are in luck as the 'Seeds of Eaden' seed shop currency has two specialist cultivars as part of their standard range.

Mammoth Blanch Leek - 100 seeds

Mammoth Blanch Leek seed has been specifically selected to become a superior exhibition variety. It is extremely tall, displays an extra long blanch and can be grown to over 3kg in weight! It is frost hardy and has excellent flavour for the kitchen.

Mammoth Pot Leek - 100 seeds

Mammoth pot leek is a true pot leek, very thick with short blanch of approximately 5.5". Although it has been bred for exhibiting, it still retains a good flavour with tight flesh. It is very frost hardy. Pot leeks are so called not because they are often grown in pots but because the lower stem is said to be pot-shaped!

Growing giant leeks is still a highly competitive game and as such the secrets to achieving these massive sizes is often a closely guarded secret. However, many growers will sow their seed in December in 3-4 inch pots using a good quality compost such as John Innes.

After a few weeks they can be potted on into 1 litre pots containing John Innes 'No 2' with perlite or vermiculite added for extra drainage.

This production is carried out  under the protection of a heated greenhouse or polytunnel and given approximately 10 hours a day of supplemental lighting until late February. Of course this can also be achieved in a cool bright room in the house or conservatory.

Maintain an average temperature of approximately 10-12 degrees Celsius but try to avoid going over 14 degrees Celsius with pot leeks as they will grow too long.

Pot on giant leeks every 3 weeks using fresh compost until they are in a 3 litre pot. Once the threat of late frosts have passed they can be hardened off and planted out in their final positions at the end of May.
