Companion planting is a time-tested gardening technique that enhances plant growth, improves pest control, and maximizes space efficiency. In this guide, we will explore the best plants to grow alongside kale and how they contribute to a healthier, more productive garden.
Why Companion Planting is Beneficial for Kale
Companion planting is the practice of strategically placing plants together to create a mutually beneficial environment. This method enhances soil quality, repels harmful pests, attracts beneficial insects, and improves overall plant health. For kale, which is prone to pests like aphids, flea beetles, and cabbage worms, having the right neighbors can make all the difference.
Key Benefits of Companion Planting with Kale:
Natural Pest Control: Some plants repel pests that commonly attack kale.
Attract Beneficial Insects: Certain flowers and herbs attract pollinators and predatory insects that feed on pests.
Soil Improvement: Leguminous plants fix nitrogen in the soil, benefiting kale’s growth.
Efficient Use of Space: Growing companion plants maximizes garden space and prevents weed growth.
Top 10 Companion Plants for Kale
Sweet Alyssum – A Natural Insect Magnet
Sweet alyssum is an excellent companion for kale as it attracts beneficial insects like hoverflies, parasitic wasps, and ladybugs. These predatory insects feast on aphids and other kale pests, reducing the need for chemical insecticides.
How to Plant:
Scatter sweet alyssum seeds around kale beds.
Maintain a distance of 12-18 inches between plants to allow proper airflow.
Marigolds – A Natural Pest Deterrent
Marigolds emit a strong scent that repels nematodes, aphids, and flea beetles. Their vibrant blooms also attract pollinators, improving the overall health of your garden.
How to Plant:
Plant marigolds around the perimeter of kale beds.
Space them 8-12 inches apart for optimal coverage.
Beans and Peas – Natural Nitrogen Boosters
Leguminous plants like beans and peas improve soil quality by fixing nitrogen, an essential nutrient for kale. Their vining growth habit also provides natural shade, preventing soil from drying out.
How to Plant:
Sow beans and peas around kale in a staggered pattern.
Use trellises to support climbing varieties without shading out kale excessively.

Dill – A Predator-Attracting Herb
Dill is a powerhouse companion plant that attracts wasps and ladybugs, natural predators of kale pests. Its presence also confuses cabbage moths, reducing their impact on kale plants.

Best Practices for Companion Planting with Kale
To ensure success with companion planting, follow these best practices:
Rotate Crops Annually: Avoid planting kale in the same spot every year to prevent soil-borne diseases.
Ensure Proper Spacing: Give plants enough room to prevent overcrowding and competition for nutrients.
Use Organic Mulch: Mulching around kale and its companions retains moisture and suppresses weeds.
Monitor for Pests: Regularly check for signs of pests and remove affected plants if necessary.
