Companion planting is a way of planting in which you inter-plant different varieties of plants to enhance growth or aid in pest control. Companion planting is based on years of experience passed down through the generations and some scientific studies.

Over all, companion planting is simply about plants helping each other- to grow better, to fend off pest and to taste better. Some plants do better when planted with a certain type of neighbor, and some should not be placed in close proximity to each other.
