The Marigold effect -
Many experienced gardeners follow a concept called companion planting: placing certain vegetables and plants near each other to improve growth for one or both plants. For example, rose growers plant garlic near their roses because it repels bugs and prevents fungal diseases. Among companion plants, the marigold is one of the best: It protects a wide variety of plants from pests and harmful weeds. If you plant a marigold beside most any garden vegetable, that vegetable will grow big and strong and healthy, protected and encouraged by its marigold.
