Companion planting is the practice of planting different plants together that benefit each other in some way. When it comes to kale, there are several companion plants that can help improve its growth and ward off pests. Understanding companion planting is essential for every gardener to maximize their kale harvest.

Let’s dive into the benefits of companion planting for kale and how to choose the right companion plants.

Benefits Of Companion Planting For Kale

  • Natural pest control: Certain companion plants have properties that repel common pests, such as aphids and cabbage moths. By interplanting kale with these beneficial plants, you can minimize the risk of insect damage.
  • Enhancing flavor: Some companion plants can enhance the flavor of kale. For example, herbs like dill and garlic can add a delightful taste to your kale dishes when grown together.
  • Providing shade and support: Tall companion plants like tomatoes or corn can provide shade to kale during hot summer days. Additionally, they can act as natural trellises, supporting kale plants that tend to grow vertically.
  • Improving soil health: Certain companion plants, such as legumes like peas or beans, are nitrogen fixers. This means they can enrich the soil with nitrogen, which is essential for kale’s healthy growth and development.
  • Attracting beneficial insects: Flowers like marigolds or nasturtiums are known to attract pollinators and other beneficial insects. These insects can help with pollination and also prey on kale pests, maintaining a balanced ecosystem in your garden.

How To Choose The Right Companion Plants

  • Consider growth habits: Choose companion plants with compatible growth habits to prevent overcrowding. Opt for plants that have similar light and water requirements to ensure they thrive together.
  • Pest repellent properties: Look for companion plants known for their pest-repellent properties. Plants like sage, thyme, and mint can help deter pests that commonly affect kale.
  • Plant diversity: Aim for a diverse mix of companion plants to create a balanced and healthy garden ecosystem. Combining different species helps attract a wide range of beneficial insects and promotes overall plant resilience.
  • Succession planting: Plan your companion planting strategy to ensure a continuous supply of fresh produce. Integrate plants with varying maturity dates, so you can replace harvested plants with new ones, maximizing your kale production.
  • Learn from experience: While there are general guidelines for companion planting, it’s essential to observe and learn from your own garden. Experiment with different companion plants and take note of their interactions with kale to find the most suitable combinations.

Remember, companion planting is not an exact science, and the effectiveness may vary depending on your local climate and specific garden conditions. Have fun exploring different companion plants for your kale and enjoy the benefits of a thriving vegetable garden.

When it comes to kale, there are several fantastic companion plants that can offer a range of benefits. In this section, we’ll explore the top companion plants for kale, focusing on planting companions, shade and soil enhancers, and pest controllers.

Planting Companion: Intercropping Herbs And Flowers

  • Mint: This aromatic herb not only adds a refreshing flavor to your culinary creations but also acts as a natural pest repellant. Its strong scent helps deter pests like aphids, ants, and flea beetles, keeping them away from your kale.
  • Nasturtiums: These vibrant flowers not only add beauty to your garden but serve as excellent trap crops. Nasturtiums attract pests like aphids, whiteflies, and cabbage worms, acting as sacrificial plants. They divert the attention of these pests away from your kale, protecting it from damage.
  • Marigolds: Known for their vibrant orange and yellow hues, marigolds aren’t just visually appealing. They also possess natural nematode-repellent properties. Planting marigolds alongside kale helps deter harmful nematodes that can attack the roots of your plants.

Shade And Soil Enhancers:

  • Beans: As legumes, beans have the remarkable ability to fix nitrogen in the soil. This nitrogen fixation benefits not only the beans themselves but also neighboring plants like kale. Additionally, the tall and leafy nature of bean plants provides much-needed shade to kale during hot summer months.
  • Borage: This herbaceous plant not only improves soil fertility but also acts as a magnet for pollinators. Planting borage near kale helps enhance soil health by accumulating nutrients and attracting beneficial insects like bees and butterflies that aid in pollination.
  • Clover: Clover is often used as a cover crop to protect and improve the soil. When grown as a companion to kale, clover acts as a natural ground cover, suppressing weeds and preventing soil erosion. It also adds essential nutrients to the soil as it decomposes.

Pest Controllers:

  • Dill: If you want to keep cabbage worms at bay, dill is an excellent companion for kale. Its strong scent repels these pests, reducing the risk of infestation. Additionally, planting dill near kale can attract beneficial insects like wasps and ladybugs, which feed on cabbage worm eggs.
  • Catnip: Apart from attracting the attention of our feline friends, catnip is also a potent pest repellant for kale. It helps deter flea beetles and aphids, preventing them from causing damage to your plants.
  • Onions: The sharp and pungent smell of onions can ward off various pests in your garden. Planting onions near kale confuses and distracts pests, creating a barrier of protection. Additionally, the flavor of onions can enhance the taste of kale in your cooking.

By choosing the right companion plants for your kale, you can create a harmonious garden ecosystem that promotes growth and protects against pests.
