If you are a gardener who loves growing kale, you may have already heard about the benefits of companion planting. Companion planting is the practice of growing two or more plants together for mutual benefits, such as improved growth, pest control, and soil health. In the case of kale, companion planting can help improve its flavor, yield, and resistance to pests and diseases.
One of the most popular companion plants for kale is the marigold. Marigolds are known for their ability to repel harmful insects, such as aphids and whiteflies, that can damage kale leaves. They also attract beneficial insects, such as ladybugs and lacewings, that feed on these pests. Other companion plants for kale include dill, coriander, and calendula, which also have insect-repelling properties and can attract pollinators to your garden.
If you are interested in trying out companion planting for your kale, it is important to choose plants that are compatible with kale’s growth requirements and do not compete for resources. You should also consider the timing of planting and the placement of companion plants in relation to your kale. With the right combination of companion plants, you can create a thriving kale garden that is both beautiful and productive.
Benefits of Companion Planting for Kale
Companion planting is the practice of growing different plants together for mutual benefits. When it comes to kale, companion planting can offer several benefits that can help improve the growth and health of your crop. Here are some of the benefits of companion planting for kale:
Improved Growth
Companion plants can help improve the growth of kale by providing shade, which can help prevent the soil from drying out and keep the plant cool during hot weather. Additionally, some companion plants can help improve soil quality by fixing nitrogen, which is an essential nutrient for plant growth.
Pest Control
Companion planting can help repel or deter pests that can damage kale, such as aphids, cabbage worms, and flea beetles. For example, planting marigolds, coriander or dill with kale can help repel aphids, while planting mint or thyme can help deter cabbage worms.
Beneficial Insects
Companion plants can also attract beneficial insects to your garden, such as parasitic wasps and predatory insects. These insects can help control garden pests by parasitizing or preying on them, which can help reduce the need for pesticides. For example, planting yarrow or dill with kale can attract parasitic wasps, which can help control aphids.
Disease Prevention
Companion planting can also help prevent diseases that can affect kale. For example, planting garlic or onions with kale can help repel pests and reduce the risk of fungal diseases. Additionally, planting herbs like oregano or thyme with kale can help prevent the growth of harmful bacteria and fungi in the soil.
In conclusion, companion planting can offer several benefits to kale growers, including improved growth, pest control, beneficial insects, and disease prevention. By choosing the right companion plants for your kale, you can help improve the health and yield of your crop while reducing the need for pesticides and other harmful chemicals.

Companion Plants to Avoid Planting with Kale
When planning your kale garden, it’s important to consider which plants to avoid planting alongside it. Some plants can attract pests or diseases that can harm your kale crop. Here are some companion plants to avoid planting with kale:
- Brassica family: Avoid planting other members of the Brassica family, such as broccoli, cauliflower, and cabbage, near kale. These plants are susceptible to the same pests and diseases as kale, and planting them together can increase the risk of infestation.
- Nightshades: Plants in the nightshade family, such as tomatoes, peppers, and eggplants, should also be avoided. These plants can attract pests such as aphids and whiteflies, which can spread to your kale crop.
- Beans and peas: Avoid planting legumes such as beans and peas near kale. These plants can fix nitrogen in the soil, which can lead to an overabundance of nitrogen and affect the growth of your kale.
- Mint: While mint can be a beneficial companion plant for some crops, it should be avoided when planting kale. Mint can attract aphids and other pests that can harm your kale crop.
- Fennel: Fennel can also attract pests such as aphids and spider mites, which can spread to your kale plants. It’s best to plant fennel away from your kale crop.
By avoiding these companion plants, you can help ensure a healthy and thriving kale garden.
Avoiding Negative Interactions
When choosing companion plants for kale, it is important to consider the potential negative interactions that may occur. Negative interactions can lead to reduced growth, yield, and quality of kale. Here are some tips to help you avoid negative interactions:
1. Avoid planting with plants that attract pests
Certain companion plants can attract pests that may harm kale. For example, planting kale near plants that attract aphids may result in aphid infestations on your kale. To avoid this, choose companion plants that do not attract pests. You can also use repellent plants to deter pests from your kale.
2. Choose plants that do not compete with kale
Competition for resources such as water, nutrients, and light can negatively affect kale growth and yield. To avoid this, choose companion plants that do not compete with kale for resources. Plants with different root depths and growth habits are good choices.
3. Avoid planting with weeds
Weeds can compete with kale for resources and also serve as hosts for pests and diseases. To avoid weed growth, choose companion plants that can act as living mulches or ground covers to suppress weed growth.
4. Avoid using pesticides
Pesticides can harm beneficial insects and pollinators that play an important role in the ecosystem. To avoid this, choose companion plants that can attract beneficial insects and serve as natural pest control. You can also use organic pest control methods such as neem oil, soap sprays, and companion planting with repellent plants.
By following these tips, you can choose companion plants that will promote the growth and health of your kale without negatively impacting it.
Harvesting and Taste
When it comes to harvesting kale, it’s best to wait until the leaves are at least six inches long before cutting them. This will ensure that the plant has enough time to develop a strong root system and produce plenty of leaves for future harvests. You can harvest kale by cutting the outer leaves with a sharp knife or scissors, leaving the inner leaves to continue growing.
In terms of taste, kale is known for its slightly bitter flavor, but this can vary depending on the variety and growing conditions. Some kale varieties have a sweeter taste, while others are more spicy or earthy. The taste of kale can also be affected by the season in which it is grown. Kale that is harvested in cooler weather tends to be sweeter and more tender, while kale grown in warmer weather can be tougher and more bitter.
Kale is a relatively easy plant to grow, making it a great choice for beginners. It thrives in cooler weather and can be planted in the spring or fall. Kale can also be grown in containers, making it a good option for those with limited space.
Kale Companion Plants – Final Thoughts
When it comes to companion planting, kale has several good companions, including beets, carrots, celery, and onions. These plants can help to repel pests and improve soil health. However, it’s important to avoid planting kale with other members of the brassica family, such as broccoli and cauliflower, as they can attract the same pests and diseases.
If you’re looking to add some interest to your kale garden, consider planting different varieties of kale with varying colors and textures. Some popular varieties include curly kale, dinosaur kale, and red Russian kale. These varieties can add visual interest to your garden and provide a range of different flavors and textures to your meals.
