Kale plants with various companion plants in a garden setting

As a gardener with over 15 years under my belt in the beautiful Midlands, I’ve had my fair share of trial and error when it comes to companion planting. Kale is a staple in many British gardens, prized for its resilience and nutritional punch. But did you know that what you plant alongside kale can significantly impact its health and productivity? In this guide, I’ll share my top tips for companion planting with kale, tailored to our UK climate.

Quick Answer

Plant kale with companions like onions, garlic, and nasturtiums to deter pests and enhance growth. Avoid planting near tomatoes and strawberries.

Why Companion Planting with Kale?

Companion planting is more than just a nifty gardening trick; it's a thoughtful strategy to maximise the health and yield of your crops. Kale benefits from companions that repel pests, improve soil health, or provide a beneficial growing environment.

Best Companion Plants for Kale

Here are some tried and tested companions for kale that thrive in our UK gardens:

  • Onions and Garlic: These alliums deter common pests like aphids and cabbage worms.
  • Nasturtiums: Act as a trap crop, luring pests away from your kale.
  • Beetroot: They grow well together without competing for resources.
  • Chamomile: Enhances the flavour of kale when planted nearby.

Companion Planting Table

Here's a simple guide to when you can plant these companions alongside kale throughout the year:

Month Companion Plant Action

May - June Nasturtiums Sow seeds directly
July - August Beetroot Direct sow seeds

Plants to Avoid Near Kale

Not all plants play nicely with kale. Here are a few you should keep at a distance:

  • Tomatoes: They can stunt kale's growth and compete for nutrients.
  • Strawberries: Both attract similar pests, which could lead to infestations.

Practical Tips for UK Gardens

Here in Staffordshire, we enjoy a reasonable growing season, but timing and preparation are key. Start your kale seedlings indoors in late winter, around February, to give them a head start. Transplant to the garden after the last frost, usually in April.

Ensure your soil is well-draining and rich in organic matter. A weekly watering schedule should suffice, but be mindful of the rainy British summer, which might require less frequent watering.
