Growing Leeks in Ireland

This is my first year growing leeks and I want to make a passionate effort to succeed. There is some effort required and the seed packet instructions fall a bit short of directing you towards a decent crop. Leeks can be sown in situ but sowing in a seed bed/module is preferable as it allows deep planting.

There are a few stages involved:

Stage 1: Sowing the seed

Normally from March-April. Plant your seed in modules (I am using empty toilet rolls) of moist compost. A depth of 1cm is commonly advised. I have also been told that seeds should be covered by a layer matching their own depth. Keep the soil moist. A mild place is suitable for the seedlings (10-15˚F).


Stage 2: Planting Out

This occurs about two months after planting, when leeks are pencil-thick and about 8 inches long.

Leeks are hungry so plant out in prepared ground that has been fertilised (e.g. manure/compost). Using a dibber (or a twig found on the ground if you are me!), make a hole about 6 inches deep. Place the leek in the hole and fill up with water, not soil.


Stage 3: Earthing Up


The reason the planting hole is filled with water, not soil, is to allow the leek to be covered gradually. This will happen naturally as soil is washed into the water, slowly taking over. Once the hole is filled, the stems must be gradually earthed up further - say a layer of soil/organic matter once a week. This process of slowly covering the leek is to achieve the white (blanched) stem, which we all know is the best part and makes the vegetable look so magnificent. Try to build the soil up by dragging it from all sides to surround the leek, rather than shovelling it on, as it may get inside the layers of the vegetable.

The leek is a slow maturing crop and most varieties will withstand extreme weather to stay in the soil all winter. Healthy plants require ample spacing of about 9 inches each way.


Stage 4: Harvesting and Eating!

As you can see, the stem is nicely blanched with a lot of white. My earthing up paid off.


Depending on sowing times and varieties, your crop will be ready to enjoy from early winter. I eat leek mostly in a casserole with chicken and sausages, or in soup. If you have any better suggestions, please leave a comment!
