Associate friendly plants

Crop associations consist of growing certain plants in the same place at the same time. This technique is part of the more global concept of permaculture. It is an alternative cultivation approach aimed at respecting the environment while offering products that are healthy for people.

For this, it goes without saying that pesticides are avoided! To do without it, crop associations are a great help. Some plants have the ability to repel pests, others limit the appearance of diseases. There are even plants that will enrich the soil, ideal for the most greedy vegetable plants!

Two types of associations

  • The allelopathic effect: it is about the beneficial or harmful effects of plants on each other.
  • Positioning and intercropping: it is about using the characteristics of plants wisely. For example, asparagus will create shade, or fast growing radishes can be sown at the same time as other plants that are slower to rise.

The 3 sisters

It is surely one of the most famous associations of cultures! Traditionally used by the Aztecs, it combines corn, beans and squash (only Cucurbita maxima).

The corn will serve as a support for the bean which has a climbing habit. The latter has the ability to fix nitrogen in the air to release it back into the soil. Finally, the squash keeps the soil cool thanks to its large leaves. This intelligent combination takes advantage of every advantage of plants while saving space on the ground.

Here is a non-exhaustive list of companion plants or, on the contrary, to be avoided.
