What Is Companion Planting

Definition and Explanation

Companion planting is a gardening technique that involves planting different types of plants together to enhance growth, deter pests, control weeds, improve nutrient availability, promote pollination, and enhance flavor. It is based on the concept that certain plants have beneficial relationships with each other when grown in close proximity.

When you practice companion planting, you carefully select plant combinations that can complement each other and provide mutual benefits. This technique has been used for centuries and is rooted in the principles of permaculture and organic gardening.

Benefits of Companion Planting

There are numerous benefits to practicing companion planting in your garden. One of the primary advantages is pest control. Some plants naturally repel certain pests, while others attract beneficial insects that can prey on harmful pests. By strategically planting these companion plants together, you can create a natural pest management system without the need for chemical pesticides.

Companion planting can also help control weeds. By planting certain plants close together, they can act as natural mulch and shade the soil, preventing weed growth. Additionally, some plants release chemicals that inhibit weed germination, further reducing the need for manual weeding.

Another benefit of companion planting is nutrient enhancement. Certain plants have deep root systems that can bring nutrients from the lower layers of soil to the surface, benefiting shallow-rooted plants nearby. Additionally, some plants have the ability to fix nitrogen from the air into the soil, enriching it with this essential nutrient.

Companion planting can also promote pollination, which is crucial for the reproduction of many plants. By planting flowers and herbs that attract pollinators, such as bees and butterflies, near your vegetable or fruit plants, you can increase pollination rates and ultimately improve yields.

Lastly, companion planting can enhance the flavor of certain crops. Some plants, when grown together, can improve the taste of neighboring plants. For example, growing basil near tomatoes is said to enhance the flavor of the tomatoes.

Common Types of Companion Planting

There are various types of companion planting techniques that you can employ in your garden based on your specific needs and goals. Here are a few common ones:

  1. Trap Cropping: This technique involves planting a sacrificial crop near your main crops to attract pests away from them. For example, planting marigolds alongside your vegetables can lure pests such as aphids and nematodes away from your valuable plants.

  2. Nurse Cropping: When you have a crop that requires some shade or protection, you can plant a taller or leafy plant nearby to provide shade or act as a windbreak. For instance, planting corn or sunflowers next to delicate lettuce can protect it from strong winds or scorching sun.

  3. Complementary Planting: This involves planting two or more crops together that have mutually beneficial characteristics. For example, planting corn, squash, and beans together in a traditional Native American “Three Sisters” garden. The corn provides a trellis for the beans to climb, while the squash acts as ground cover, preventing weed growth and maintaining soil moisture.

  4. Allelopathic Planting: Some plants release natural chemicals that inhibit the growth of other plants. By strategically planting these allelopathic plants, you can suppress the growth of weeds. For instance, growing sunflowers near weed-prone areas can help control weed populations.

Plant Combinations for Pest Control

One of the key benefits of companion planting is its ability to deter pests naturally. By carefully selecting plant combinations, you can create a garden ecosystem that discourages harmful insects and attracts beneficial predators.

Here are some common plant combinations for pest control:

  1. Marigolds and tomatoes: Marigolds emit a scent that repels nematodes, which can damage tomato roots. By planting marigolds alongside your tomato plants, you can minimize nematode infestations.

  2. Basil and tomatoes: Basil has strong aromatic compounds that repel pests like tomato hornworms and aphids. Planting basil near your tomato plants can help deter these pests and protect your tomato crop.

  3. Nasturtiums and radishes: Nasturtiums act as a trap crop for aphids, attracting them away from your radishes. This can help protect your radish crop from aphid infestations.

  4. Lavender and roses: Lavender is known to repel aphids, which can damage rose plants. By planting lavender near your roses, you can help keep aphids at bay and maintain the health of your rose bushes.

Plant Combinations for Weed Control

Weeds are a common nuisance in any garden. However, by practicing companion planting, you can effectively control weed growth and reduce the need for constant weeding.

Here are some plant combinations for weed control:

  1. Corn and beans: Planting corn in a dense pattern can create shade that helps suppress weed growth. Interplanting beans with corn provides additional weed control as the beans grow up the cornstalks, smothering weeds in the process.

  2. Lettuce and garlic: Garlic releases sulfur compounds that deter weed seed germination. By planting lettuce alongside garlic, you can inhibit the growth of weeds in your lettuce bed.

  3. Mint and cabbage: Mint plants release a pungent aroma that deters many insects, including cabbage moth. Planting mint near your cabbage plants can help protect them from cabbage moth infestations and reduce the need for pesticides.

Companion Planting for Nutrient Enhancement

Certain plants have the ability to enhance nutrient availability in the soil, benefiting neighboring plants. This can be especially useful for crops that have high nutrient requirements.

Here are some examples of companion planting for nutrient enhancement:

  1. Legumes and brassicas: Legumes, such as peas and beans, have nitrogen-fixing bacteria in their root nodules. These bacteria convert atmospheric nitrogen into a form that plants can use. By planting legumes near brassicas like cabbage or broccoli, you can enrich the soil with nitrogen, which is essential for healthy growth.

  2. Comfrey and fruit trees: Comfrey has deep roots that can mine nutrients from the subsoil. Planting comfrey near fruit trees allows it to bring up nutrients like potassium and phosphorus, which are important for fruit production.

  3. Cover crops and garden beds: Planting cover crops like clover or vetch in between growing seasons can help improve soil fertility. These cover crops act as green manure, adding organic matter to the soil and increasing nutrient levels.

Companion Planting for Pollination

To ensure good pollination and maximize fruit or vegetable yields, companion planting can play a crucial role. By attracting pollinators, such as bees and butterflies, to your garden, you can enhance the pollination process and increase harvests.

Here are some examples of companion planting for pollination:

  1. Flowering herbs and vegetables: Planting flowering herbs like lavender, thyme, and oregano near your vegetable plants can attract bees and other pollinators. This increased pollinator activity can lead to better fruit set and higher yields.

  2. Sunflowers and cucumbers: Sunflowers produce large, showy flowers that attract bees and butterflies. By planting sunflowers near cucumber plants, you can encourage pollination and improve cucumber production.

  3. Borage and strawberries: Borage is a flowering herb that is highly attractive to bees. Planting borage near strawberry plants can increase pollination rates and result in larger, sweeter strawberries.

Companion Planting for Enhancing Flavor

Companion planting can also enhance the flavor of certain crops by influencing their growth and development. This can result in tastier and more flavorful harvests.

Here are some examples of companion planting for flavor enhancement:

  1. Basil and tomatoes: Planting basil near tomatoes is not only beneficial for pest control but can also improve the flavor of tomatoes. The aromatic compounds released by basil can infuse the tomatoes with a delightful taste.

  2. Dill and cucumbers: Dill has a strong fragrance that complements the flavor of cucumbers. By planting dill near your cucumber plants, you can elevate the taste of both crops.

  3. Rosemary and beans: Rosemary has a unique flavor that can enhance the taste of beans. Consider planting rosemary near your bean plants to add a delicious herbal undertone to your dishes.

Tips for Successful Companion Planting

To make the most of companion planting in your garden, here are some tips to keep in mind:

  1. Research plant compatibility: Not all plants make good companions. Before planting, research which plants are suitable companions and which ones should be kept apart. Some plants may inhibit each other’s growth or attract the same pests, leading to competition or increased pest pressure.

  2. Observe and adjust: Pay attention to how your companion plants are interacting. If you notice any negative effects, such as stunted growth or increased pest infestations, adjust your planting arrangements accordingly.

  3. Plan your garden layout: Before planting, consider the spacing requirements and growth habits of your plants. Ensure that companion plants have enough space to grow without overcrowding each other.

  4. Rotate your crops: To prevent nutrient depletion and pest buildup, practice crop rotation. Avoid planting the same crop or plants from the same family in the same location year after year.

  5. Provide proper care: Even with companion planting, it’s essential to provide proper care to your plants. This includes regular watering, mulching, fertilizing as needed, and monitoring for pests and diseases.


Companion planting is a holistic and sustainable gardening technique that can benefit both your plants and the environment. By understanding the principles and practice of companion planting, you can create a harmonious garden ecosystem that promotes healthy growth, controls pests and weeds, enhances nutrient availability, improves pollination, and elevates flavor.

So, the next time you plan your garden, consider the power of companion planting. You’ll be amazed at the positive impact it can have on the overall health and productivity of your plants. Happy gardening!
