Companions for asparagus or any other vegetable must be compatible with each other. Asparagus is a perennial that likes a sunny area of the garden. They take 2-3 years to reach a full yield and, thereafter, produce spears for the next 10-15 years! This means that companions for asparagus must like sun exposure and be able to work around the semi-permanent asparagus.

Asparagus Loves ….

Tomatoes keep asparagus roots cool and deter asparagus beetles. In turn asparagus deters nematodes that destroy tomatoes. Basil deters other pests and improves the flavour of tomatoes.

  • Parsely – helps with plant vigor
  • Basil – helps with plant vigor
  • Tomato – plant alongside asparagus to help deter asparagus beetles (basil is also said to improve the flavour of tomatoes) and in turn, asparagus deters nematodes that are enemies of tomato.

Herbs and Flowers:

  • Marigolds – deters pests such as spider mites and aphids
  • Comfrey – plant around the edges of the bed to give asparagus enough room to grow. Comfrey conditions the soil.
  • Coriander – deters some pests
  • Dill – plant at the edge of a bed so as to give the asparagus room to grow. Deters some pests.


NB: Be careful when companion planting with these herbs and flowers, because while they are friendly for asparagus, they may not be friendly with other companion vegetables, such as tomatoes, planted with the asparagus. Make sure each plant is compatible with the others before placing them in the same areas.
