What Is Companion Planting?

We choose our friends, and people will hang around due to specific reasons. It could be their sense of humor, goodness, and kindness. For these reasons and more, we choose people that complete us.

Plants and other herbs need companions too. They need suitable companion plants like us humans do except it helps in repelling garden pests.

Plants that they can help grow and benefit from also.  It is suitable for these plants to be closer to each other to enhance strength, improve soil nutrients, and boost growth. 

That is what companion planting is. It is growing a family of plants that can benefit from each other next to each other.

Companion Planting works in 2 ways. Both companion plants benefit from each other equally, or one is benefiting just from the other.

Here are the two ways they work. 

1. Mutualism is a relationship where both organisms benefit from each other equally. In a mutual relationship, both organisms are involved in exchanging resources such as shelter, food, or other nutrients.

They can also exchange services like protection. 

For example, bush beans and corn are companion plants. The corn protects the beans, and the beans boost the nitrogen level in the soil for the corn. Cauliflower notes and spinach are also in a mutual relationship.

2. Commensalism is a relationship where one organism benefits and the other neither benefits nor gets harmed. The other organism remains unaffected. It resides like it’s invisible. No pain, No gain! 

In this case, sage flowering herbs repels flies that destroy carrots but does not get any benefit from carrots. It doesn’t get harmed either. A natural insect repelling pair.
