Best Companion Plants for Pest Control

A gardener’s biggest nuisance, pests pose a significant challenge to the growth and well-being of all plants. From mosquitos and aphids to slugs and snails, the presence of garden pests can lead to wilted leaves, black spots, mangled and shriveled flower growth, and even dying plants. Fortunately, gardeners can ward off invasive pests and preserve their garden’s livelihood through the usage of companion planting.

A traditional gardening methodology observed across generations, companion planting involves the practice of growing plants together to derive a certain benefit. Useful for generating a more vigorous plant growth and attracting pollinators like bees and butterflies, this technique has also been proven to invite beneficial insects, as well as repel disruptive pests.
