10 Best Basil Companion Plants for Maximizing Basil’s Potential

Basil is a favorite among cooks and gardeners alike for its flavorful leaves and culinary versatility. However, did you know that you may improve the flavor and development of basil while keeping pests away by planting it with particular companion plants? 

In this article, we’ll delve into the world of basil companion plants and find the ideal plant combinations to maximize the health and yield of your basil.

What Is Companion Planting?

Companion planting is a gardening practice in which many plants are carefully grown together to benefit one another. The practice is based on the principle that certain plants have inherent affinities for one another and can help one other grow when planted close together. Companion planting can improve soil health, repel pests, attract beneficial insects, and increase crop yields.

Consider this: your basil plants thrive, bursting with aromatic leaves and repelling pests. This isn’t simply garden luck; it’s the hidden power of companion planting. Consider your basil surrounded by allies, each with its own benefits that contribute to a vibrant ecosystem. This is the core of companion planting!

It’s more than just aesthetics; it’s about utilizing the natural relationships between plants. Plants, like humans, form relationships with their neighbors. Some operate as beneficent defenders, attracting helpful insects and repelling destructive ones. 

Others promote each other’s growth by sharing nutrients or improving soil conditions. Understanding these linkages allows you to develop a garden that grows naturally, avoiding the need for harsh chemicals and promoting biodiversity.

What Are the Benefits of Companion Planting?

Companion planting provides numerous advantages for gardeners seeking to improve plant development and overall garden health. Here are some major benefits of adopting companion planting into your gardening practices:

  • Pest Control: Some companion plants produce natural compounds that repel pests or attract predatory insects that eat typical garden pests. Planting marigolds alongside foods like tomatoes, for example, can help avoid nematodes and aphids while also attracting beneficial insects like ladybugs and hoverflies, which prey on pests.
  • Improved Soil Health: Many companion plants have deep or widespread root systems that help to break up compacted soil, improve soil structure, and boost nutrient availability. Leguminous plants, such as peas and beans, are especially valuable because they fix nitrogen in the soil, which enriches it for nearby plants.
  • Pollinator Paradise: Borage and marigolds attract bees and butterflies with their colorful blossoms. These pollinators promote optimal fruit sets for surrounding tomatoes and peppers and help basil by boosting ventilation and lowering the danger of fungal disease.
  • Enhanced Flavor: Believe it or not, some buddies can change the flavor of your basil! Cilantro, despite its contentious reputation, is considered to enhance the flavor of basil when grown nearby. Chamomile and chives may also contribute to a richer, more nuanced basil profile, offering an extra layer of flavor to your culinary creations.
  • Weed Control: Certain companion plants, such as ground cover crops like clover or vetch, can help reduce weed development by shading the soil and competing for sunshine, water, and nutrients. This lessens the need for human weeding and lowers weed pressure in the garden.
  • Improved Water Retention: Companion planting encourages better water management in the soil. Ground coverings such as thyme help to retain moisture, decreasing the need for frequent watering. Taller plants with larger leaves, such as sunflowers, can help provide shade and reduce soil evaporation.

These are just a few advantages that await you when you harness the power of companion planting for your basil. In the following part, we’ll look more closely at certain plant pairings that can benefit your garden.

Plants to Avoid Growing With Basil

While basil flourishes when planted with some partner plants, several plants may inhibit its growth or flavor if grown close. Here are a few plants to avoid growing alongside basil:

  1. Fennel: Fennel is known to impede the growth of neighboring plants by allelopathy, a process in which chemicals are released that prevent the growth of other plants. Planting fennel near basil will restrict its development and alter its flavor, so keep the two herbs separate in the garden.
  2. Rue: Rue, like basil, can hurt neighboring plants. Rue has chemicals that can hinder the growth of surrounding plants and may alter the flavor of basil if planted close together. To avoid potential problems, grow rue apart from basil.
  3. Cucumbers: Some gardeners believe cucumbers and basil are lovely companions, but others advise against planting them together. Some research indicates that cucumbers may decrease basil growth, whereas others claim no detrimental effects. To be safe, keep cucumbers and basil separate in your yard.
  4. Anise: Anise is a member of the carrot family (Apiece). Thus, it may compete with basil for nutrients and soil resources. Planting anise near basil may reduce basil’s growth and productivity; therefore, avoid planting them together in the yard.
  5. Mint: Mint is noted for its rapid growth and invasive characteristics, which can drown out surrounding plants like basil. Planting mint alongside basil may cause competition for space, water, and nutrients, resulting in lower growth and productivity for both plants. It is better to keep mint in separate pots or regions of the garden from basil.


Can I grow basil next to other herbs like parsley or cilantro?

While basil can be cultivated alongside other herbs, it is vital to consider their compatibility and cultural needs. Parsley and cilantro, for example, have different requirements for sunlight, water, and soil conditions than basil.

Planting them together may not be optimal unless each herb’s unique requirements are met. Before selecting companion plantings, learning about each herb’s specific requirements is best.

Will planting basil with other herbs or vegetables affect its flavor?

Depending on the plants cultivated alongside, Basil’s flavor can be influenced by companion planting. For example, basil planted near aromatic herbs such as rosemary or lavender may absorb slight flavor distinctions from their fragrant oils.

However, planting basil beside strongly flavored or allelopathic plants like fennel or rue may hurt its flavor. Experimenting with various companion plants will help you identify which combinations produce the most delicious flavors.

Are there any specific plants that attract pests to basil?

While companion planting can help keep pests away from basil, some plants may unintentionally attract pests that can harm basil plants. For example, planting dill or celery near basil may attract pests such as aphids or caterpillars that eat basil leaves.

It is critical to periodically monitor the garden for indicators of pest infestations and take necessary actions to manage them, such as handpicking pests or employing organic pest management methods.


In conclusion, companion planting is a comprehensive approach to gardening that promotes biodiversity, pest management, and general plant health. By carefully selecting which plants to grow alongside basil, gardeners may build a vibrant garden ecology that maximizes each plant’s benefits.

With a little experimentation and observation, gardeners may find the ideal companions for their basil plants and reap abundant harvests season after season.
