Can You Plant Kale and Blackberries Together?

Companion planting is a popular gardening technique that involves growing different plants together to enhance growth, deter pests, and optimize space. Gardeners often explore the compatibility of various plant pairings, such as kale and blackberries, to maximize their garden’s productivity. In this article, you’ll learn whether these two plants can be effectively grown together and discover tips for successful companion planting.

Compatibility Analysis

The short answer is: No, kale and blackberries are not ideal companions. While both can thrive in a garden, their differing growth requirements and potential competition for resources make them less compatible. Kale prefers cooler temperatures and can tolerate partial shade, while blackberries need full sun and warmer conditions. Additionally, blackberries are perennial and can dominate garden space, potentially overshadowing the shorter, annual kale plants.

Key Factors

• Growth Requirements: Kale grows best in cooler weather, whereas blackberries need full sun and warmer temperatures.
• Pest Control: Blackberries can attract pests like aphids and mites, which may also target kale.
• Nutrient Needs: Both plants require nutrient-rich soil, but blackberries’ extensive root systems can deplete soil nutrients, affecting kale growth.
• Spacing: Blackberries’ sprawling nature can overshadow kale, limiting its access to sunlight.

Benefits of Planting Together

While kale and blackberries aren’t the best companions, they can still offer some benefits if grown in proximity with proper management:

• Pest Repellent Properties: Kale’s strong scent can deter some pests from blackberries.
• Space Efficiency: By careful planning, you can optimize garden space by using vertical supports for blackberries and planting kale in the forefront.
• Pollinator Attraction: Blackberries attract pollinators, which can benefit nearby plants, including kale.

Potential Challenges

• Resource Competition: Blackberries’ extensive root systems can compete with kale for nutrients and water.
• Different Watering Needs: Kale requires consistent moisture, while blackberries need less frequent watering.
• Disease Susceptibility: Both plants can be affected by fungal diseases, which might spread more easily when grown together.
• Harvesting Considerations: Blackberries’ thorny canes can make harvesting kale more challenging.

Practical Solutions

• Use raised beds to separate the root systems.
• Implement drip irrigation to manage different watering needs.
• Regularly prune blackberry canes to prevent overshadowing.

Planting Tips & Best Practices

• Optimal Spacing: Keep at least 3 feet between blackberry bushes and kale plants.
• Timing: Plant kale in early spring or fall, while blackberries should be planted in late winter or early spring.
• Container vs. Garden Bed: Consider growing kale in containers if space is limited or if you want to manage soil conditions separately.
• Soil Preparation: Enrich soil with compost before planting to ensure both plants receive adequate nutrients.
• Additional Companion Plants: Consider planting onions or garlic, which can deter pests and complement both kale and blackberries.
