It is also a good idea to plant onions among your leeks as they will discourage aphids.

How To Plant Leeks

The planting of leeks is a job that can be quite easily accomplished. A few hours of your time and a little effort will provide you with a crop that is well worth the outlay of energy and money.

The first thing you need to decide upon is the position in which you are going to plant them.

If this is a new garden and you have already prepared the soil, you should make a shallow trench about 15cm deep and up to 30cm wide. If the soil is heavier and tends to compact, then make the trench only 10cm deep.

Use a fork or hoe to prepare a trench for each seedling.

Plant the seeds around 15cm apart. Once the seedlings are big enough to handle you can carefully transplant them into their final position.

How To Use Leeks


Leek flowers can be dried and used in flower arrangements.


If you grow leeks for fun (which is difficult to believe) then you could try this little experiment. Take a paper bag, poke a few holes in it and place it over the plants when they are still seedlings.

As they grow the stems will thicken and become hollow, similar to an elephant’s tooth-pick. The flower stalks can also be dried and used in flower arrangements.


If you need some growing tips then all you have to do is ask a gardener. They should be able to point you in the right direction.
