Leeks should be planted 30 cm apart from other vegetables like garlic that don’t have a negative impact on them but can take up space in your garden.

Beans, Bush Beans & Peas

Beans and peas produce biochemicals that hinder the growth of leeks. When these plants are grown together, the beans and peas will stunt the growth of the leeks. This is because the bacteria found in most soils is killed by alliums including leeks.

Asparagus

When planting asparagus, you will need to make a choice between two types of plants – those that produce flowers (alliums) and those that do not (asparagus). If you choose to plant alliums, you will need to disadvantage the asparagus plants by removing them or by preventing them from flowering. This is because the alliums will take up the space and nutrients that the asparagus needs in order to grow properly. Alternatively, if you do not want to plant alliums, it is best to keep alliums out of your asparagus bed. This is because growing alliums in an asparagus bed would be disadvantageous and not suitable.
