Companion Planting: Getting Started

Companion planting is a gardening technique that involves growing different plants together to benefit each other. It is a traditional farming practice that has been used for centuries to improve crop health, increase yields, and repel pests. In this guide, we will explore the definition and history of companion planting, discuss its benefits, and provide tips on how to get started.

Definition of Companion Planting

Companion planting is the practice of growing two or more plant species together in close proximity, taking advantage of the interactions between them. These interactions can be symbiotic or mutually beneficial, such as repelling pests, improving nutrient uptake, enhancing pollination, or providing shade and support.

History of Companion Planting

Companion planting has a long history and can be traced back to ancient civilizations. Native American tribes, for example, practiced the “Three Sisters” technique, which involves planting corn, beans, and squash together. The corn provides support for the beans to climb, while the beans fix nitrogen in the soil, benefiting all three plants. The squash acts as a natural mulch, suppressing weeds and conserving moisture.

Benefits of Companion Planting

Companion planting offers numerous benefits for both plants and gardeners. By planting compatible species together, you can create a diverse and balanced ecosystem in your garden, promoting plant health and productivity. Some of the key benefits of companion planting include:

  1. Pest and Disease Control: Certain plants can repel pests or attract beneficial insects, reducing the need for chemical pesticides. For example, planting marigolds alongside tomatoes can help deter nematodes, while attracting hoverflies that feed on aphids.

  2. Soil Enhancement: Some plants have deep roots that can help break up compacted soil, while others fix nitrogen or accumulate certain nutrients, improving soil fertility. For instance, planting legumes like peas or beans can replenish nitrogen levels in the soil.

  3. Pollination and Fruit Set: Planting flowers that attract pollinators near fruiting plants can increase pollination rates and improve fruit set. Bees and other pollinators are essential for many crops, such as tomatoes, peppers, and cucumbers.

Factors to consider

Before diving into companion planting, it’s important to consider certain factors to ensure successful results. Here are some key factors to keep in mind:

Plant Compatibility

Not all plants are compatible with each other, and some combinations may actually hinder growth or attract pests. It’s important to research and understand the compatibility and interaction between different plant species before deciding on companion planting combinations. There are several resources available, such as companion planting charts or guides, that can help you determine which plants work well together.

Pest and Disease Control

Companion planting can be an effective strategy for pest and disease control. Certain plants can repel pests or attract beneficial insects that feed on common garden pests. For example, planting garlic or onions near your roses can help deter aphids, while attracting ladybugs that feed on aphids and other harmful insects.

Soil Enhancement

Companion planting can enhance soil fertility through the use of nitrogen-fixing plants or those that accumulate specific nutrients. This is particularly beneficial for long-term garden health. For example, planting legumes like peas or beans can help replenish nitrogen levels in the soil, benefiting neighboring plants.

Common Companion Planting Combinations

Now that we have covered the basics of companion planting, let’s explore some common combinations that are known to work well together:

Tomatoes and Basil

Tomatoes and basil are considered classic companions in the garden. Basil can repel pests like whiteflies and aphids, while enhancing the flavor of tomatoes. Plant basil near your tomatoes to deter pests and enhance growth.

Carrots and Onions

Carrots and onions make great companions as they have different root depths. Onions repel pests like carrot flies, while carrots help deter onion flies. Planting them together can help reduce pest problems and improve growth.

Corn, Beans, and Squash (Three Sisters)

The Three Sisters technique is a Native American tradition that involves interplanting corn, beans, and squash. The corn provides support for the beans to climb, while the beans fix nitrogen in the soil. The squash acts as a natural mulch, suppressing weeds and conserving moisture. This combination creates a sustainable and symbiotic ecosystem.

Companion Planting Techniques

There are various techniques you can use when implementing companion planting. Here are three popular methods:


Interplanting involves planting companions together in the same bed or row. This method maximizes space and allows plants to interact closely with each other. For example, you can interplant lettuce with radishes, as radishes mature quickly and create shade for the lettuce during the hot summer months.

Trap Cropping

Trap cropping involves planting specific plants to attract pests away from your main crops. This technique is useful for diverting pests from sensitive plants. For example, planting marigolds near your tomatoes can attract nematodes away from the tomatoes, serving as sacrificial plants.

Succession Planting

Succession planting involves planting different crops in the same space at different times throughout the growing season. This technique maximizes the use of space and extends the harvest period. For example, you can plant lettuce and spinach together, and when the lettuce is harvested, the spinach will have room to grow.

Companion Planting Layouts

There are different layouts you can consider when implementing companion planting in your garden. Here are three common layouts:

Traditional Row Planting

The traditional row planting layout involves planting in neat rows, with each row having a specific combination of companion plants. This layout is useful for larger gardens and makes it easier to maintain and harvest crops.

Square Foot Gardening

Square foot gardening involves dividing your garden into small square plots and planting different crops in each square. This layout is space-efficient and also allows for easy planning and crop rotation.

Circular Planting

Circular planting involves planting in concentric circles, with the center usually having taller plants and the outer circles having shorter companions. This layout is aesthetically appealing and can create a sense of symmetry in your garden.

Avoiding Companion Planting Mistakes

While companion planting can be beneficial, it’s important to avoid common mistakes that may hinder its success. Here are a few mistakes to avoid:

Planting Incompatible Combinations

Not all plant combinations are beneficial. Some combinations may compete for resources, attract pests, or hinder growth. It’s crucial to research and understand the compatibility of plant species before deciding on companion planting combinations.

Neglecting Proper Spacing

Plant spacing is essential for the health and growth of your plants. Overcrowding can lead to poor air circulation, reduce sunlight penetration, and promote the spread of diseases. Make sure to follow spacing recommendations for each plant species and consider their growth habits.

Not Rotating Crops

Crop rotation is an important practice in companion planting. It helps prevent pest buildup, reduces disease transmission, and optimizes nutrient uptake. Avoid planting the same crops in the same location year after year, as this can deplete the soil and increase the risk of pests and diseases.

Attracting Beneficial Insects

Beneficial insects play a crucial role in organic gardening by feeding on pests and pollinating plants. Here are some tips on attracting beneficial insects to your garden:

Importance of Beneficial Insects

Beneficial insects, such as ladybugs, lacewings, and hoverflies, can help control common garden pests without the need for chemical pesticides. They are natural predators that feed on harmful insects, keeping their populations in check.

Plants to Attract Beneficial Insects

Certain plants can attract beneficial insects to your garden. These include dill, fennel, yarrow, sunflowers, and a variety of flowering herbs. Planting these flowers and herbs alongside your crops can help attract beneficial insects and promote a healthy ecosystem.

Creating Insect-Friendly Habitats

In addition to planting beneficial insect attractants, creating insect-friendly habitats can further encourage their presence in your garden. Providing shelter, such as by leaving small patches of undisturbed vegetation or building insect hotels, can offer hiding places and breeding sites for beneficial insects.

Companion Planting Tips for Specific Crops

Different crops have different companion planting requirements and benefits. Here are some tips for companion planting specific crops:

Companion Planting for Tomatoes

Tomatoes benefit from companions such as basil, marigolds, and parsley. Basil repels tomato hornworms, while marigolds deter nematodes. Parsley attracts hoverflies, which feed on aphids and other pests.

Companion Planting for Peppers

Peppers can benefit from companions such as basil, oregano, and marjoram. These herbs can repel aphids, spider mites, and other common pests. Planting them together can help keep pests at bay.

Companion Planting for Herbs

Many herbs have natural pest-repellent properties and can be beneficial companions for other plants. For example, planting mint near cabbage can deter pests like cabbage moths and aphids.
