A diversified garden uses a variety of plant odors, colors, and textures as natural pest barrier. Cabbage moths are confused when the scent of broccoli and cabbage are masked by onions and carrots growing next door.
Companion planting is a way to encourage your plants to thrive by strategically placing certain plants near each other.
It benefits your garden in several ways: by attracting beneficial insects and bug-eating birds as well as providing nutrients and protecting against disease. A bonus for you and your family: some companion plants also deter pest insects, according to the North Carolina State University Cooperative Extension. Garlic can be a good companion plant because it deters a variety of pests, including mosquitoes. Try planting it with beets, eggplants, tomatoes, peppers and broccoli. Basil helps neighboring plants such as lettuce, peppers and tomatoes thrive, and also repels mosquitoes.
You can grow companion plants as a border around other plants, mixed within rows or interspersed throughout a bed.
