What are the types of companion planting

Companion planting is typically categorized by the type of benefit it provides. These benefits include pest control, soil improvement, pollination, and nutrient cycling.

Soil Improvement

Certain plants can improve the soil by adding nitrogen, making it easier for other plants to absorb nutrients. Legumes, such as beans and peas, are known for their ability to fix nitrogen in the soil. This means that they take nitrogen from the air and convert it into a form that other plants can use.


Many plants require insects for pollination. By planting certain plants that attract beneficial insects, such as bees and butterflies, you can increase the amount of pollination in your garden.

Tips for Companion Planting

  1. Choose companion plants that are compatible with each other. Some plants may have beneficial relationships while others may be harmful or compete for resources. Research the plants you want to plant together to make sure they are compatible.

  5. Plant a variety of plants. This will help to attract beneficial insects and create a more diverse ecosystem.
  6. Experiment and have fun! Companion planting is an art, so don’t be afraid to try different combinations and see what works best for you.
