This post is all about companion planting peppers.

Fundamentals of Companion Planting Peppers

To optimize your pepper yields and garden health, understanding the fundamentals of companion planting is essential. This method not only enhances growth but also naturally mitigates pests.

Benefits of Companion Planting for Peppers

Companion planting benefits peppers by improving pollination rates, promoting healthier growth, and reducing the need for chemical pesticides. Certain plants can create a favorable microclimate or deter pests. 

Which plants do well with peppers and which ones don’t?

Choosing Compatible Plants

Key criteria for choosing companion plants for peppers include similarity in growing conditions and complementary attributes. Some plants, like corn, provide shading and support, while others like garlic work as pest deterrents. It’s crucial to avoid plants that may compete for resources or attract diseases, such as the cabbage family.

Understanding Pepper Growth Habits

Peppers thrive in well-drained soil with ample sunlight and prefer a warm growing environment. They don’t like frost. Although most sources state peppers enjoy full sun, I’ve personally found that they need a rest from the sun during the summer months. If they can have a little bit of shade, they’re happier. Another important growing habit to keep in mind is that peppers take a long time to grow and, depending on the variety, usually don’t have a high yield. Recognizing that peppers have a relatively long growing season and moderate water needs will guide you in selecting compatible companions. 

Let’s now take a look at some of their friends and foes.

Tomatoes and Peppers Companion Planting

Planting tomatoes and peppers together is a little iffy. Tomatoes need a lot of space and a lot of airflow. They can be susceptible to diseases and pests if there isn’t proper airflow. Not only do tomatoes get bushy and expand horizontally, but a lot of varieties get very tall, especially if they’re a vine. The recommended spacing between tomato plants is 18 to 24 inches. Peppers on the other hand can be planted closer together. They can be planted 12 to 18 inches apart. Since tomato plants get very tall, they have the ability to block out sunlight to pepper plants. 

If you’re going to plant them together, give enough space between plants.

Carrots and Peppers Companion Planting

Carrots and peppers mutually benefit from one another. Peppers provide shade to carrots, while the roots of the carrot keep the soil from becoming compacted. Carrots also provide coverage to keep weeds at bay, which is a huge win. The less weeds, the better! Lastly, carrots attract beneficial insects like ladybugs and lacewings.

Basil and Peppers Companion Planting

Basil, with its distinct aroma and taste, benefits greatly from being planted alongside tomatoes and peppers. It may help repel pests such as whiteflies and improve the flavor of their companion plants. Basil attracts beneficial insects like bees and butterflies. It repels asparagus beetles, carrot fly, tomato hornworm, mosquitoes, flies, and white flies. Thankfully peppers and basil get along very well for these reasons and don’t conflict with their growing habits. So feel free to companion plant basil and peppers!

Dill and Peppers Companion Planting

This herb is actually a really beautiful plant to have in the garden. It has feathery green foliage and if it’s left to bolt, it grows tiny flowers. The plant attracts all kinds of beneficial insects. There have been a couple of times when I sacrificed my plant so that black swallowtail butterfly caterpillars could feed. It likes warm weather, lots of sun and can even tolerate a light frost! It doesn’t take long to start bringing this herb from the garden to table either with a harvest time frame in about 50 to 70 days.

Planting dill and peppers together is a great space saver. However, in general dill should be kept away from nightshades. Dill can negatively affect the health of nightshades so it’s best to avoid planting pepper and dill together. 

Squash and Peppers Companion Planting

Squash and peppers are a great pair. While peppers grow vertically, squash sprawl across the ground. Squash gives shade to the soil, provides ground coverage to prevent weeds, and helps to retain moisture in the soil. So interplant squash and peppers.

Peppers and Beans Companion Planting

Beans and peppers aren’t good companions. They’re foes because they compete for nutrients in the soil. Beans need a lot of nitrogen to grow, thereby robbing peppers of the nitrogen they need. This will leave your pepper plants stunted. Vining beans can also rob your peppers of sunlight, which affects their growth and their ability to produce a crop.

Onions and Peppers Companion Planting

Onions are a perfect companion for many different vegetables. Their strong aroma does wonders for repelling insects. Peppers are affected by pests such as slugs and cabbage worms, which onions deter. They don’t compete with peppers for space or resources, which is another added bonus. Onions don’t need a lot of room to grow and keep the soil from becoming compact.

Corn and Peppers Companion Planting

Corn and peppers make for an excellent companion planting duo, as their unique characteristics contribute to a mutually beneficial relationship in the garden. The towering stalks of corn provide a natural support structure for the typically smaller and bushier pepper plants, offering them shade and protection from strong winds. In return, the peppers act as living mulch, suppressing weed growth around the base of the corn and conserving soil moisture. Additionally, the two plants have distinct nutrient needs, reducing competition for resources in the soil. Corn is a heavy nitrogen feeder, while peppers thrive with less nitrogen and more phosphorus. This complementarity helps ensure that each plant receives the nutrients it requires for optimal growth. The result is not only a visually striking garden but also a more efficient and productive cultivation system, where corn and peppers collaborate harmoniously to yield a diverse and abundant harvest.

Nasturtium Companion Planting Peppers

Nasturtiums are one of my new favorite flowers! They give so much color to the garden and they’re so cute. They prove to be a remarkable companion to peppers in the garden, forming a symbiotic relationship that enhances the overall health and productivity of both plants. These vibrant, edible flowers act as natural deterrents to common garden pests like aphids and whiteflies, effectively safeguarding the neighboring pepper plants from potential infestations. Furthermore, nasturtiums serve as a living ground cover, suppressing weed growth and helping to retain soil moisture around the pepper roots. The peppery and aromatic essence of nasturtiums also acts as a natural repellent for certain insects that may threaten pepper plants. Beyond their pest-repelling qualities, nasturtiums contribute to the garden’s aesthetic appeal, creating a visually pleasing and diverse landscape. They also attract beneficial insects. With their dual role as both defenders and beautifiers, nasturtiums emerge as an invaluable companion for peppers, fostering a balanced and thriving garden ecosystem.

Peppers and Cabbage Companion Planting

Cabbage and peppers unfortunately don’t do well together. In fact, all brassicas and peppers are not fans of each other. Cabbage are really heavy feeders like all brassicas, so they rob peppers of their needed nutrients. Avoid planting these together.

Companion Planting Cucumbers and Peppers

Companion planting cucumbers with peppers unveils a synergy that goes beyond mere spatial arrangement, creating a garden dynamic where each plant contributes to the other’s success. Cucumbers, with their sprawling vines, offer natural ground cover that helps suppress weed growth around the base of pepper plants, minimizing competition for nutrients and water. The upright structure of pepper plants, in turn, provides essential shade for the more delicate cucumber leaves, shielding them from excessive sunlight and potential sunscald. Additionally, peppers emit compounds that can deter common cucumber pests like aphids and cucumber beetles. This natural pest-repelling mechanism reduces the need for chemical interventions and fosters a healthier growing environment. The combination of these two crops not only maximizes space utilization but also creates a symbiotic relationship, resulting in a more resilient and productive garden where cucumbers and peppers thrive side by side.

Thyme and Peppers Companion Planting

Companion planting thyme with peppers is a flavorful and strategic partnership that yields benefits beyond the culinary realm. Thyme, with its aromatic leaves, acts as a natural repellent against certain pests that commonly trouble pepper plants, such as aphids and spider mites. The antimicrobial properties of thyme may also help prevent soil-borne diseases that can affect pepper roots. In return, the pepper plants provide a protective microclimate for thyme, sheltering it from harsh environmental conditions and promoting its vigorous growth. Moreover, thyme’s low, spreading habit serves as an effective ground cover, helping to suppress weeds around the base of pepper plants and conserve soil moisture. This dynamic pairing not only enhances the health and resilience of both plants but also adds a delightful herbaceous element to the garden. As thyme and peppers thrive together, the result is not only a visually appealing garden but also a harmonious ecosystem where culinary and gardening pleasures unite.

Mint and Peppers Companion Planting

Companion planting mint with peppers introduces a harmonious collaboration in the garden, blending culinary delights with practical benefits. Mint’s strong aromatic qualities act as a natural deterrent for pests that commonly trouble pepper plants, such as aphids and flea beetles. The invigorating scent of mint can mask the attractants that draw these pests, contributing to a healthier and more pest-resistant pepper patch. 

Additionally, the low, spreading growth habit of mint serves as an effective ground cover, suppressing weed growth around the base of pepper plants and conserving soil moisture. While peppers provide a protective canopy for the more delicate mint leaves, the combination also introduces a sensory experience, creating a garden space that appeals to both the palate and the senses. This strategic pairing not only enhances the overall health of both plants but also adds a refreshing and aromatic layer to the garden, where mint and peppers thrive together in a mutually beneficial companionship.

Keep in mind that mint is a very vigorous grower!

Peppers and Potatoes Companion Planting

Potatoes are part of the same nightshade family as tomatoes and peppers. They both need the same types of nutrients to flourish and therefore compete for them. Therefore they should not be planted together.

Companion Planting Brussel Sprouts and Peppers

Brussel Sprouts are another type of brassica, which as previously discussed, do not go well together with peppers. All brassicas, including Brussel sprouts are heavy feeders. They require a lot of nutrients from the soil to grow. Because of this, the pepper plants would be nutrient deficient and have all kinds of issues.

Parsley and Peppers Companion Planting

Pairing parsley with peppers in companion planting introduces a dynamic synergy that extends beyond the culinary realm, creating a mutually beneficial relationship in the garden. Parsley, with its lacy foliage, acts as a natural insectary, attracting beneficial insects like hoverflies and parasitic wasps that prey on aphids and other common pests that affect pepper plants. This not only aids in pest control but also fosters a healthier, more balanced ecosystem. 

In return, peppers provide a sheltering canopy for the delicate parsley leaves, protecting them from harsh sunlight and creating a microenvironment conducive to optimal growth. The presence of parsley in the pepper patch not only enhances biodiversity but also contributes to the visual appeal of the garden. This thoughtful combination of parsley and peppers exemplifies the potential for companion planting to create a symbiotic partnership that goes beyond individual plant health, promoting a thriving and resilient overall garden ecosystem.

Radishes and Peppers Companion Planting

Introducing radishes as companions to peppers in the garden adds a practical and symbiotic dimension to cultivation. Radishes, known for their rapid growth, act as natural soil aerators with their deep taproots, breaking up compacted soil and enhancing the overall soil structure. This benefits peppers by allowing their roots to penetrate the soil more easily and access nutrients efficiently. 

Additionally, radishes serve as sacrificial plants, attracting root-damaging pests like nematodes away from peppers, thus acting as a natural pest deterrent. The quick turnaround time of radishes also makes them an excellent intercrop, utilizing space efficiently and providing an early harvest before the peppers reach their full size. This thoughtful pairing not only maximizes garden productivity but also demonstrates the strategic benefits of combining plants with complementary growth patterns and characteristics.

Peppers and Broccoli Companion Planting

Broccoli is yet another brassicas. Avoid planting them together.

Peppers and Watermelon Companion Planting

Watermelons are another type of heavy feeder. No nightshades (tomatoes, eggplants, peppers, etc) do well planted with watermelon. They’ll compete for nutrients like phosphorus and nitrogen.

Green Beans and Peppers Companion Planting

The partnership between green beans and peppers in companion planting not only maximizes space but also enhances each other’s growth through a harmonious exchange of benefits. Green beans, with their climbing vines, provide an excellent vertical element that complements the more compact nature of pepper plants. As green beans ascend, they create a living trellis that supports pepper plants, reducing the need for additional staking and providing mutual structural benefits. 

In return, the shade provided by pepper plants shields the base of green bean vines from excessive sun exposure, helping to prevent soil moisture loss and reduce the risk of sunscald. Moreover, the two plants have distinct nutrient needs, with green beans enriching the soil with nitrogen, which peppers, in turn, benefit from. This strategic pairing not only ensures efficient use of garden space but also establishes a cooperative relationship that promotes a healthy, balanced, and bountiful harvest.

Companion Planting Peppers and Zucchini

Companion planting peppers with zucchini offers a dynamic alliance that enhances the overall health and productivity of both crops. Zucchini’s expansive, low-growing leaves provide natural ground cover, suppressing weed growth around pepper plants and conserving soil moisture. In return, the upright growth habit of pepper plants offers shade to the more sprawling zucchini, protecting it from the scorching sun and promoting a favorable microclimate. Furthermore, the two plants have distinct pest vulnerabilities, with zucchini being susceptible to certain pests like squash bugs and aphids, while peppers may face threats from spider mites and flea beetles. 

By interplanting these crops, the risk of pest infestation is diversified, as the presence of one can help deter pests that commonly afflict the other. This strategic pairing not only maximizes space utilization but also fosters a symbiotic relationship that contributes to a thriving and resilient garden, where peppers and zucchini coexist harmoniously for a more abundant and balanced harvest.

Implementing Companion Planting Strategies

Layout and Spacing Considerations

To create a beneficial ecosystem for your peppers, careful planning is important. You’ll want to ensure there is adequate space between your plants to promote air circulation and reduce disease spread. A typical layout may involve planting peppers with a spacing of 18 to 24 inches apart in rows that are about 30 to 36 inches apart. Then, intersperse companion plants like onions and other alliums which can help repel pests and improve pepper plant health, while respecting their space requirements as well.

Complementary Planting Techniques

Strategically pairing peppers with compatible plants can lead to a range of benefits. For instance, planting basil near your peppers can enhance flavor and deter pests. Incorporate flowering plants like sweet alyssum to attract beneficial insects which can aid in pest control and pollination.
