This document provides a chart listing which plant species grow well together based on companion planting principles, plants that help protect other plants from pests, and plants that are inhibited by other plants. It includes which vegetables and herbs have beneficial or detrimental effects when planted near each other, such as tomatoes being protected from insects when planted with basil or onions. The information aims to help gardeners with crop planning and pest management.
