Why Does Borage Need Companion Plants?

Repel Insects and Pest Control

Borage is an herb that can repel insects and pests, such as tomato hornworms, cabbage worms, and squash bugs. This characteristic makes it a popular companion plant for vegetables like tomatoes, squash, and cabbage.

Why Does Borage Need Companion Plants?

Borage contains compounds that attract pollinators like bees while deterring harmful insects. It also produces a strong scent that can mask the scent of other susceptible plants, making them less appealing to pests. This natural pest control method is beneficial for organic gardeners, as it reduces the need for chemical insecticides.

Bring Pest Predators

Besides repelling pests, borage also attracts beneficial insects like ladybugs, lacewings, and predatory wasps. These insects are natural predators of common garden pests and can help keep your plants healthy without the use of harmful chemicals.

Planting borage near susceptible crops can bring these pest predators to your garden, creating a balanced ecosystem that benefits all plants. This is especially helpful for plants that are prone to aphid infestations, as ladybugs and lacewings are known to feed on these pests.

Improve Soil Health

Borage is a deep-rooted plant that can reach up to 2 feet in the ground. Its extensive root system helps break up compacted soil, allowing air and water to flow more freely. This improves soil drainage and prevents waterlogging, which can lead to root rot in plants.

Additionally, borage’s leaves and flowers are rich in nutrients such as nitrogen, potassium, and calcium. When these parts of the plant decompose, they release these nutrients into the soil, making it more fertile for other plants to grow. Planting borage near nutrient-hungry plants can help replenish the soil and improve overall plant health.

Increase Nutrients in Food

Not only does borage improve the soil’s nutrient content, but it can also increase the nutritional value of foods grown nearby. The flowers and leaves of borage are edible and rich in vitamins and minerals like vitamin C, calcium, and iron.

When planted near other crops, borage’s root system can bring up these nutrients from deep within the soil and make them more accessible to neighboring plants. As a result, the vegetables grown near borage can have a higher nutritional value, making them healthier for consumption.

Benefit from Borage’s Shade and Moisture

Borage is a fast-growing plant that can reach up to 3 feet in height. Its large leaves create shade for nearby plants, protecting them from the scorching sun and reducing water evaporation from the soil.

Additionally, borage has a high water requirement and can help retain moisture in the soil. This is especially beneficial for plants that require consistent moisture, such as cucumbers and lettuce. Planting borage in between rows of these plants can help keep the soil moist and reduce water stress on them [1].

Top 3 Worst Companion Plants for Borage



Borage and potatoes are often mistaken to be good companion plants because of borage’s ability to repel tomato hornworms. However, borage can hurt the growth and development of potatoes. Borage has been found to reduce potato yields by inhibiting the growth of their roots. This makes it difficult for potatoes to absorb nutrients from the soil, leading to stunted growth and smaller yields.

To avoid this issue, it is best to keep borage at a distance from potato plants. If you still want to grow these two plants together, make sure to plant them in separate containers or at least 3-4 feet apart in the garden.


Fennel is a great companion plant for many plants, but not for borage. Both plants contain high amounts of nectar and attract similar pollinators, creating competition for resources. This can lead to decreased pollination and reduced yields for both plants.

In addition, fennel produces compounds that can inhibit the growth of borage and other nearby plants. This can lead to stunted growth and smaller yields for borage.

To avoid these issues, it is best to keep fennel and borage separated in the garden. If you want to grow them together, make sure to plant them at least 3-4 feet apart.

Black Walnut Trees

Black walnut trees produce a chemical called juglone, which can be toxic to many plants. Borage is particularly sensitive to juglone and can quickly wither and die when planted near black walnut trees.

In addition, the shade produced by black walnut trees can also negatively affect borage’s growth and development. Borage requires full sun for optimal growth, so planting it near black walnut trees may result in smaller and less productive plants.

To avoid these issues, it is best to keep borage at least 50-60 feet away from black walnut trees. If you have limited space, consider growing borage in containers or raised beds to protect them from the harmful effects of juglone.
