Companion planting is a broad term that encompasses many different methods, but the central idea is that some plants help other plants grow. This may come in the form of deterrents, fragrant plants like mint, lavender, and other herbs. While humans may love the smell and taste in small amounts, lining a garden with herbs can help keep unwanted wildlife, such as deer, rabbits, and chipmunks, out. While these fragrant flowers keep out many mammals, they are a favorite for many pollinators. Another form of companion planting is all about insects. Other plants, such as marigolds and basil, attract beneficial insects. Beneficial insects, such as ladybugs, parasitic wasps, and damselflies, reduce pests like aphids, cabbage moths, and tomato hornworms. There are also potential benefits to your soil; root vegetables like carrots and radishes work to loosen up compacted soil, and legumes like beans and peas add nitrogen back in. Companion planting also maximizes your limited garden space while suppressing weeds. With so many different benefits, companion planting is a wonderful way to get the most out of your garden.
