Farming is often viewed as a battle against nature, where plants are forced to compete for limited resources. However, agricultural science increasingly shows that crops can also cooperate. This article explores the concept of companion cropping, a practice in which different plants are grown together to support one another. In particular, it examines the practical relationship between Garlic and Coriander, where Coriander helps protect young Garlic plants by moderating sunlight exposure, while Garlic reduces pest pressure through its strong natural odor. By also reviewing classic examples such as maize, beans, and squash, this article demonstrates how working with natural plant interactions can improve crop health while reducing dependence on chemical inputs.
