Companion planting is an age-old gardening technique that pairs plants together to enhance growth, deter pests, and improve soil health. I feel it is a very good idea to understand how to include companion planting into your garden because it can lead to healthier plants and bigger harvests. I want to break down the basics, share some tips to get you started and debunk common myths that come up when talking about companion planting.
What Is Companion Planting?
Companion planting is the practice of strategically growing certain plants together to create a more productive and balanced garden. Some plants naturally support each other by improving soil nutrients, repelling pests, or providing shade and structural support. By using these helpful relationships, you can create a productive and more resilient garden ecosystem.
This method has been practiced for centuries and is a fundamental aspect of organic gardening. Indigenous cultures, such as the Native American Three Sisters method, have long used this technique to grow corn, beans, and squash together for mutual benefit.
Why Companion Planting Works
Companion planting offers multiple advantages, including:
1. Natural Pest Control: Certain plants help discourage insects that could harm neighboring plants. For example:
Marigolds emit a scent that repels aphids and nematodes.
Basil planted near tomatoes can deter tomato hornworms.
Nasturtiums act as a trap crop, attracting aphids away from vegetables.

2. Soil Health Improvement: Plants interact with the soil in different ways, some adding nutrients while others deplete them. Pairing plants correctly can help conserve soil fertility. For example:
Legumes (beans, peas) fix nitrogen in the soil, benefiting nitrogen-loving plants like corn.
Deep-rooted plants like carrots help aerate the soil, making nutrients more accessible.
3. Increased Yields and Growth: By planting compatible crops together, you can maximize space while increasing productivity. Climbing plants like pole beans can use tall corn stalks as natural trellises, saving space while benefiting both plants. (This is an example of the 3 sisters method I talked about earlier.)
4. Weed Suppression Some plants create ground cover that prevents weeds from taking over, such as:
Squash with large leaves shading out weeds.
Clover acting as a living mulch, keeping weeds at bay and enriching the soil.
Tips to Incorporate Companion Planting in Your Garden
Plan Your Layout – Before planting, map out which crops will go where based on their compatibility. Use companion planting charts for guidance.
Diversify Your Garden – Avoid monoculture (planting large sections of one crop) to reduce pest infestations and soil depletion.
Use Herbs to Your Advantage – Herbs like basil, rosemary, and dill not only improve the flavor of vegetables but also repel harmful insects.
Experiment and Observe – What works in one garden may not work in another. Keep a garden journal to track successes and failures.
Incorporate Flowers – Flowers like marigolds, calendula, and sunflowers attract beneficial insects such as pollinators and predatory insects that keep pests in check.
Common Myths About Companion Planting
Like any gardening method, companion planting comes with a few myths that have been passed down over time. Here are some common misconceptions:
“Carrots love tomatoes” – This popular phrase comes from a book title, but research hasn’t proven a significant benefit between the two.
“Marigolds repel all pests” – While marigolds deter some pests, they do not offer full protection from all garden insects.
“Companion planting guarantees higher yields” – While it can improve plant health, factors like soil quality, climate, and care play a bigger role in success.
Best Books on Companion Planting
If you want to dive deeper into companion planting, these books offer reliable guidance:
Carrots Love Tomatoes by Louise Riotte – A classic book that popularized the concept of companion planting.
Rodale’s Successful Organic Gardening: Companion Planting by Fern Marshall Bradley – A detailed guide on plant pairings and organic gardening strategies.
Great Garden Companions by Sally Jean Cunningham – A practical approach to designing your garden with companion planting.
Final Thoughts
Companion planting is a simple yet effective way to enhance your garden naturally. By understanding plant relationships, you can reduce pests, improve soil health, and create a more productive garden space. Whether you’re growing vegetables, herbs, or flowers, implementing companion planting strategies will lead to a healthier, more balanced garden.
That said, it’s important to remember that gardening is as much about experience and experimentation as it is about knowledge. The science of soil and how it can improve over time is fascinating, and it’s true that certain pests tend to avoid the scent of certain herbs. But the best way to know what works for you is to take this knowledge and put it into action.
Start by experimenting in your own garden. Take notes and keep a journal to track your results. By doing this, you’ll not only see what works best for your environment but also begin to master the art of companion planting. It’s through hands-on experience that we truly learn and grow.
