The science behind Companion Planting

Companion planting is a trendy practice and a scientifically-proven method to enhance your garden’s productivity and sustainability. Here is why you should consider starting companion planting in your garden:

Positive plant interactions: Companion planting involves strategically pairing plants that can benefit each other through various interactions, such as improving soil quality, deterring pests, and attracting beneficial insects.

Chemical compounds: Certain plants release natural chemicals that can act as insect repellents or attractants, while others can even suppress the growth of nearby weeds or pathogens.

Nutrient sharing: Companion plants can also share nutrients through their root systems, allowing for more efficient use of soil resources.

Biodiversity: Introducing various plant species to your garden can promote biodiversity and create a more resilient ecosystem.
