Significance of companion planting

Known with various terms like intercropping, interplanting, and polyculture in the botanical world, the mechanism of companion planting involves the combination of suitably matching plants in pairs, successions, or alterations to have them benefit mutually from each other. The basic idea of companion planting focuses on planting different plants together with contrasting or matching set of qualities that help in the creation of a more diverse, richer, resilient, and utilitarian environment for each member of the group.

Here are some of the ways companion planting is advantageous:

  • It minimizes the need for artificial or commercial treatments by providing natural protection to plants.
  • The nutrients of the plants improve the soil quality by themselves without needing any additive.
  • The plants can create a beneficial pollination environment for each other by mutual elimination of insects, diseases, and other issues.
  • Some plants act as natural dividers for others and also provide benefits like air circulation, preventing diseases spread, etc.
