We've compiled a list of great companion plants that not only enhance the growth of your basil during bloom season but also repel harmful insects. These companion plants are sure to take your basil garden to the next level.

Garlic: Natural Pest Repellent

Garlic is not only a flavorful addition to many dishes but also an excellent companion plant for basil and tomato plants. Planting garlic near your basil and tomato plants helps repel pests like aphids and mosquitoes. These pesky insects can wreak havoc on your precious herbs and different plants, but with garlic by their side, they'll think twice before invading. The strong aroma of garlic acts as a natural deterrent, keeping those unwanted visitors at bay in various growing conditions, including partial shade soil type.

Eggplants: Flavor Enhancers and Pest Deterrents

Eggplants are a good companion for basil, as they enhance each other's flavor and deter pests like flea beetles. Growing them together in full sun conditions and the right soil type ensures the health and productivity of both plants during the bloom season.

Asparagus: Mulch and Weed Suppressant

Asparagus is a great companion plant for basil. When planted near your basil patch, asparagus acts as a natural mulch, conserving soil moisture and suppressing weeds. Its dense foliage provides shade that helps retain moisture in the soil while preventing weed growth. This means less time spent weeding and more time enjoying fresh basil leaves! Asparagus and basil thrive in different plants and growing conditions, making them a perfect match. Additionally, asparagus and basil are both resistant to common garden pests. Both plants also require full sun to grow properly. So, planting them together ensures they receive the necessary sunlight for healthy growth.

Cole Crops and Root Crops: Benefiting from Basil's Pest-Repellent Properties

Basil's pest-repellent properties make it an ideal companion for different plants like cabbage and radishes, which have specific growing conditions. By planting these crops alongside basil in full sun soil type, you create a natural defense system against common pests. Basil emits aromatic compounds that repel insects such as cabbage worms and root maggots, effectively protecting your cole crops and root vegetables during their bloom season.


Garlic is a good companion for basil plants, as it has natural insect-repelling properties. When planted together, they deter harmful insects and form a mutually beneficial relationship. This helps protect your basil plants from pests.

By planting garlic alongside your basil, you can reduce the risk of infestation and keep your plants healthy. The strong aroma of garlic acts as a natural repellent, making basil less attractive to pests like aphids. This makes garlic a good companion for basil, especially in full sun growing conditions.

Both garlic and basil thrive in similar growing conditions, making them compatible companions in the garden. They both prefer well-drained soil with moderate moisture levels and require ample sunlight to flourish. By planting them together, you can create an environment that meets their shared needs while maximizing space in your garden. Additionally, both garlic and basil have different bloom seasons, with garlic typically blooming in the summer and basil blooming in the spring. When fully grown, garlic can reach a size of several feet, while basil typically grows to a height of a few inches.

In addition to protecting basil from pests, planting garlic nearby can benefit other crops in your garden. For example, tomatoes, which require full sun and specific soil types, are commonly grown alongside basil due to their complementary flavors and culinary uses. By adding garlic, a good companion plant for tomatoes and basil, you create a trio of plants that not only enhance each other's taste but also work together to repel common insects like mosquitoes. This combination of plants thrives in optimal growing conditions and blooms during the appropriate season.

To successfully plant garlic with basil, it is important to consider the growing conditions and choose good companion plants. Garlic and basil thrive in full sun and well-drained soil. Additionally, it is essential to be aware of common garden pests that may affect both plants.

  1. Spacing: Ensure there is enough space between each plant to allow for proper growth and airflow. Garlic bulbs should be spaced around 4-6 inches apart while basil plants should have at least 12-18 inches between them.
  2. Companion Planting: Consider incorporating other companion plants that can further enhance the benefits of growing garlic and basil together. Carrots and peppers are known to complement both herbs while providing additional pest control benefits.
  3. Harvesting: Keep in mind that garlic has a longer growing season compared to annual herbs like basil. Plan accordingly so you can harvest the mature cloves without disturbing the neighboring basil plants.

By strategically planting garlic alongside your basil, you can create a natural pest repellent system while enjoying the flavors and benefits of these two good companion plants. The mutual support they provide each other in terms of taste and insect deterrence makes them an ideal combination for any garden with suitable growing conditions. So why not give it a try and see how this dynamic duo can enhance your gardening experience during their respective bloom season?


Growing eggplants alongside basil can have numerous benefits for both plants. Not only does it improve the flavor of the eggplants during bloom season, but it also helps deter common pests and provides additional advantages in your garden. These benefits are dependent on the right conditions, including full sun and the appropriate soil type, to ensure optimal growth and size of both plants.

Flavor Enhancement through Chemical Interactions

When growing basil and eggplants together, the full sun conditions enhance the flavor of the eggplants. Basil releases aromatic compounds that fuse with the eggplant leaves, creating a unique taste. This fusion elevates your culinary experience during the bloom season. Planting basil alongside your eggplants adds size, depth, and complexity to your dishes.

Natural Pest Deterrent

Eggplants are often plagued by flea beetles during bloom season, which can cause significant damage to their leaves. However, by growing basil nearby in full sun soil type, you can naturally deter these pesky insects. Basil possesses a strong scent that acts as a natural repellent for flea beetles. The aroma confuses and repels them, preventing them from infesting your precious eggplants. This natural pest deterrent saves you from resorting to harmful pesticides while ensuring healthy growth for your eggplant crop. Plus, basil grows up to 2 feet in size, making it an ideal companion plant.

Shade and Weed Control

Both basil and eggplants have dense foliage that forms a lush canopy when planted together. This dense foliage not only provides shade for each other but also shades the surrounding soil, creating ideal growing conditions. As a result, weed growth is significantly reduced in this shaded area since weeds require sunlight to thrive. By combining these two plants in close proximity, you'll be minimizing weed competition and saving yourself valuable time spent on weeding tasks. Additionally, both basil and eggplants have a similar bloom season and can grow to a substantial size.

Visual Interest in Your Garden

In addition to their practical benefits, growing basil and eggplants together in a vegetable garden adds visual interest. The vibrant green hues of the basil leaves complement the deep purple or glossy black shades of the eggplant fruits. This harmonious combination enhances the overall beauty of your garden and showcases your gardening prowess to visitors. These plants thrive in full sun and come in various sizes, making them perfect for any bloom season.

When considering what to plant alongside basil in your vegetable garden, remember that it can have positive effects on the growth and flavor of tomatoes, cucumbers, cabbage, carrots, potatoes, bell peppers, radishes, beets, turnips, and lettuce. By strategically planning your garden layout and incorporating basil into different sections, you can create a thriving ecosystem where different plants benefit from one another's growing conditions. Make sure to provide full sun for optimal results during the bloom season.


Considering the growing conditions of basil, planting it alongside a companion plant like asparagus can greatly benefit both plants. Asparagus thrives in full sun, which is also ideal for basil. This symbiotic relationship between the two plants allows them to thrive and enjoy many benefits during their bloom season.

Asparagus acts as a natural mulch when planted alongside basil in full sun. Its tall foliage provides shade, helping to retain soil moisture and reducing the need for frequent watering. This is especially beneficial during the hot summer months when water evaporation rates are high. By acting as a protective layer, asparagus helps keep the soil cool and moist, creating an ideal environment for both plants to grow during their bloom season.

Another advantage of planting basil with asparagus is that basil's aromatic leaves help repel pests that may damage asparagus, such as aphids or beetles. Basil emits a strong scent that naturally deters these pests from infesting the neighboring plants. This means fewer worries about dealing with pesky insects that could harm your precious asparagus crop, especially when grown in full sun and under optimal growing conditions.

In addition to pest control, planting basil and asparagus together in an environment with full sun can lead to healthier growth and improved yields for both plants. The combination of these two herbs creates a diverse environment that attracts beneficial insects like parasitic wasps. These helpful creatures prey on harmful pests such as aphids or beetles, providing natural pest control without the need for chemical interventions.

When planning your garden layout, consider allocating space for parsley and chives, as they are good companion plants for your basil-asparagus duo. Parsley enhances the flavors of dishes when paired with basil while also attracting beneficial insects like bees and butterflies. Chives act similarly by attracting pollinators while deterring harmful insects like aphids. These plants thrive in full sun.

Moreover, if you have enough space available, parsnips make an excellent addition to this companionship trio. Parsnips grow well with both basil and asparagus since they have deep roots that do not compete with the shallow-rooted herbs. Their foliage provides shade and acts as a natural mulch, further conserving soil moisture.

To summarize, planting asparagus with basil offers numerous benefits. Asparagus acts as a natural mulch, reducing water evaporation and retaining soil moisture. Basil's aromatic leaves repel pests that may harm asparagus while attracting beneficial insects like parasitic wasps. By incorporating parsley, chives, and parsnips into this companion planting scheme, you can create an environment that enhances flavors, attracts pollinators, and promotes healthy growth for all three plants.

So why not consider adding some asparagus, a good companion plant, to your basil patch this season? You'll not only enjoy the culinary delights of both herbs but also reap the rewards of a thriving garden ecosystem.

Cole Crops and Root Crops

Brassicas like cabbage, broccoli, and cauliflower benefit from the pest-repellent properties of basil when planted nearby. The strong scent of basil confuses pests like cabbage worms, reducing their impact on cole crops. This natural pest control method not only helps protect your crops but also eliminates the need for harmful chemical pesticides.

Interplanting radishes and other root crops with basil can also be beneficial. These root vegetables act as trap crops, luring soil-borne pests away from your main crop while simultaneously improving overall garden health. The aromatic oils released by basil deter pests such as nematodes, which can damage the roots of plants. By combining these plants in your garden, you create a diverse ecosystem that promotes natural pest control.

When planting cole crops alongside basil, it is important to consider their growing conditions. Both brassicas and basil thrive in well-drained soil with ample organic matter. Ensure that the soil is loose and fertile to support healthy growth. Providing partial shade for both plants can help prevent excessive heat stress during hot summer months.

Root crops like radishes prefer loose soil that allows their roots to penetrate easily. Adding compost or well-rotted manure to the planting area near nearby basil plants will improve the soil structure for optimal growth. Radishes also require consistent moisture throughout their growing period to develop crisp roots.

To interplant basil with cole crops effectively, follow these steps:

  1. Select a sunny location in your garden where both plants will receive at least six hours of direct sunlight each day.
  2. Prepare the soil by removing any weeds or debris and adding organic matter such as compost or aged manure. It is important to choose a good companion plant for your nearby basil plants.
  3. Space the cole crop seedlings according to their recommended spacing guidelines.
  4. Plant basil seedlings around the perimeter of each cole crop plant, ensuring they are spaced far enough apart to allow for proper growth.
  5. Water the plants thoroughly after planting, and continue to provide regular irrigation throughout the growing season.

For interplanting basil with radishes or other root crops, follow these steps:

  1. Choose a well-drained area in your garden that receives full sun.
  2. Prepare the soil by loosening it with a garden fork or tiller and removing any rocks or large clumps.
  3. Sow radish seeds directly into the prepared soil, following the recommended spacing guidelines on the seed packet.
  4. Plant basil seedlings between each row of radishes, allowing enough space for both plants to grow without overcrowding.
  5. Water the newly planted seeds and seedlings gently but thoroughly, keeping the soil consistently moist until germination occurs.


Nasturtiums are excellent companion plants for basil due to their ability to attract beneficial insects like bees and butterflies. These vibrant flowers not only add beauty to your garden but also provide a source of nectar for pollinators. By planting nasturtiums alongside basil, you create an inviting environment that supports the natural pollination process.

One of the key benefits of growing nasturtiums with basil is their role as sacrificial plants. Nasturtiums have a unique ability to attract pests away from nearby plants, including basil. This means that pests such as aphids, whiteflies, and squash bugs are more likely to be drawn towards the nasturtiums instead of your precious basil plants. As a result, your basil remains protected from potential damage caused by these common garden pests.

In addition to acting as sacrificial plants, nasturtiums also serve as natural pest repellents. Their pungent scent acts as a deterrent for harmful insects, making it less likely for them to infest neighboring plants like basil. This is particularly useful in repelling aphids and whiteflies, which can quickly multiply and wreak havoc on your garden if left unchecked.

Another advantage of planting nasturtiums alongside basil is their ground cover properties. Nasturtium leaves provide shade and help retain moisture in the soil, creating a favorable microclimate for both plants. This can be especially beneficial during hot summer months when excessive heat can stress out delicate herbs like basil.

Other options like marigolds and tomato plants are often recommended. While these choices offer their own advantages, nasturtiums stand out due to their dual role as pest deterrents and attractive flowers that support pollinators.

To summarize the benefits of planting nasturtiums with basil:

  • Attracts beneficial insects like bees and butterflies
  • Adds beauty to your garden with vibrant flowers
  • Acts as sacrificial plants, diverting pests away from basil
  • Repels aphids, whiteflies, and squash bugs
  • Provides ground cover to retain moisture and create a favorable microclimate

Incorporating nasturtiums into your basil garden not only enhances its aesthetic appeal but also promotes a healthier ecosystem. The symbiotic relationship between these two plants creates a harmonious environment where pollinators thrive, harmful insects are deterred, and your basil flourishes. So why not give nasturtiums a try and enjoy the benefits they bring to your herb garden?


Oregano is a fantastic companion plant for basil, as it not only shares similar growing requirements but also boasts resistance to common diseases. These two herbs make an excellent pairing in the garden due to their aromatic leaves that help deter pests when grown together in close proximity.

Oregano's strong taste perfectly complements the deliciousness of basil in culinary dishes. Whether you're making a classic tomato sauce or a fresh Caprese salad, adding oregano to your basil-infused recipes will enhance their overall taste and aroma. The combination of these two herbs creates a delightful symphony of flavors that will tantalize your taste buds.

In addition to their culinary benefits, growing oregano near basil can also contribute to the health and vitality of both plants. Oregano has natural antimicrobial properties that can help protect against certain plant diseases. By planting these herbs side by side, you create an organic shield for them, minimizing the risk of infections and promoting their well-being.

Both basil and oregano require similar soil conditions for optimal growth. They thrive in well-drained soil with a slightly acidic pH level ranging from 6.0 to 7.5. Ensure the soil is rich in organic matter by adding compost or aged manure before planting.

To maximize the benefits of this dynamic duo, consider creating an herb garden where you can cultivate various companions for your basil and oregano pairings. Cilantro, fennel, borage, and chamomile are among other herbs that can be grown alongside them.

The essential oil content found in both basil and oregano contributes to their strong scents which are known to repel insects such as mosquitoes and flies. By combining these fragrant herbs together, you create an environment that naturally deters pests without relying on harmful chemicals or pesticides.

So why not take advantage of nature's synergy by planting oregano alongside your basil? Not only will you enjoy the delectable flavors they bring to your culinary creations, but you'll also benefit from their health-enhancing properties and the joy of tending to a vibrant herb garden.

The Worst Companion Plants for Basil

Basil is a popular herb known for its fragrant leaves and culinary uses. While it thrives in many gardens, it's important to consider its companions when planning your planting scheme. Some plants can have a detrimental effect on basil's growth and flavor. Here are the worst companion plants for basil:


Mint may seem like a logical companion for basil due to their shared use in cooking and similar growing conditions. However, these two herbs should be kept far apart in the garden. Mint is an aggressive plant that spreads rapidly through underground runners, often overpowering other nearby plants, including basil. To prevent mint from taking over your basil patch, keep them in separate containers or place barriers between them in the ground.


While cucumbers and basil both enjoy warm weather and ample sunlight, they are not ideal companions in the garden. Cucumbers release substances that can inhibit the growth of nearby plants, including basil. Cucumbers tend to sprawl and can overshadow smaller herbs like basil, depriving them of much-needed sunlight. To avoid stunted growth and lackluster flavor in your basil plants, keep them away from cucumber vines.


Rue is an herb with a strong scent that repels many pests but has an adverse effect on neighboring plants like basil. Rue contains compounds that can hinder the growth of nearby herbs and vegetables, including stunting the development of basil leaves. It's best to avoid planting rue near your beloved basil to ensure their optimal growth.


Sage is another herb that should not be planted alongside basil due to its allelopathic properties. Allelopathy refers to the ability of certain plants to produce chemicals that inhibit or interfere with the growth of others around them. Sage emits such compounds that can impede the development of nearby herbs like basil. To maintain healthy and thriving basil plants, keep them away from sage.


Strawberries may be a delightful addition to any garden, but they can pose a challenge when planted near basil. These two plants have different water requirements, with strawberries needing more moisture than basil. The sprawling nature of strawberry plants can overshadow and crowd out the basil, leading to reduced sunlight exposure and hindered growth. To ensure both crops flourish, it's best to separate them in your garden.

While these are some of the worst companion plants for basil, it's essential to note that not all combinations will result in failure. Gardening is an art that often involves experimentation and learning through trial and error.

Conclusion: What to Plant with Basil?

To maximize your basil garden, it's important to choose the right companion plants. By selecting the best companions for your basil, you can enhance its growth and protect it from pests. Garlic, eggplants, asparagus, cole crops and root crops, nasturtiums, and oregano are all excellent choices to plant alongside your basil.

Garlic is not only a delicious addition to many dishes but also acts as a natural pest repellent for basil. Its strong aroma helps ward off insects that could harm your plants. Similarly, eggplants provide shade for basil while deterring pests like aphids and spider mites.

Asparagus is another great companion plant for basil. It helps repel nematodes that can damage the roots of both plants. Planting cole crops such as cabbage or broccoli near your basil can help deter cabbage worms and other common pests.

Nasturtiums not only add beauty to your garden with their vibrant flowers but also attract beneficial insects like bees and ladybugs. These insects help pollinate your basil plants and control harmful pests naturally. Oregano is an aromatic herb that complements the flavors of basil while also repelling pests like aphids.

While there are many beneficial companion plants for basil, it's equally important to avoid certain combinations that may hinder its growth or attract unwanted pests. Some examples of poor companions include fennel, rue, and sage. These plants can inhibit the growth of nearby herbs like basil.

In conclusion, by selecting the right companion plants for your basil garden, you can create a thriving ecosystem that promotes healthy growth and deters pests naturally. Consider incorporating garlic, eggplants, asparagus, cole crops and root crops, nasturtiums, or oregano into your garden alongside your beloved basil.

Now go ahead and experiment with these companion plants to enjoy a bountiful harvest of flavorful herbs!
