Companion planting is a bit more than just the general notion that some specific plants can benefit others if they are planted close to each other. It has been defined as planting two or more crop species together to achieve benefits such as higher yields and pest control.
It allows you to grow herbs, veggies and exotic crops to their full potential. The process also helps to keep insects away, as well as helping you to maintain healthy soil.
