Can You Plant Kale, Lavender, and Blueberries Together?

Companion planting is a popular gardening technique that helps maximize space, improve plant health, and increase yields. When considering whether kale, lavender, and blueberries can be planted together, it’s essential to understand each plant’s unique requirements and compatibility. In this article, you’ll learn about the compatibility of these plants, their growing needs, benefits, challenges, and best practices for planting them together.

Compatibility Analysis

Can you plant kale, lavender, and blueberries together?

The short answer is no—these plants are not ideal companions. While each plant has its own merits, their differing growth requirements make them incompatible for close planting.

• Growth Requirements: Kale thrives in cool temperatures and prefers slightly acidic to neutral soil (pH 6.0-7.5). Lavender, on the other hand, requires well-drained, alkaline soil (pH 6.7-7.3) and full sun. Blueberries need acidic soil (pH 4.5-5.5) and consistent moisture.

• Pest Control: Lavender can repel certain pests, benefiting nearby plants. However, kale and blueberries have different pest profiles, meaning lavender’s pest control benefits may not apply to both.

• Nutrient Needs: Kale is a heavy feeder, requiring rich soil, while lavender thrives in poorer soils with minimal fertilization. Blueberries have specific nutrient needs, including high organic matter content.

• Spacing: Kale and blueberries can grow relatively close, but lavender’s bushy nature requires ample space, which can overshadow or compete with the others.

Growing Requirements Comparison Table

Benefits of Planting Together

While kale, lavender, and blueberries have conflicting requirements, there are some general benefits of companion planting:

• Pest Repellent Properties: Lavender’s scent can deter pests, potentially benefiting kale if planted nearby but not too close.

• Pollinator Attraction: Lavender attracts pollinators, which can indirectly benefit blueberries by increasing pollination rates.

• Space Efficiency: While not ideal together, strategic placement in a garden can still optimize space if each plant’s needs are met separately.

Potential Challenges

• Resource Competition: Kale and blueberries require different soil conditions and nutrients, which can lead to competition and poor growth.

• Watering Needs: Lavender prefers dry conditions, while blueberries need consistent moisture, making simultaneous watering difficult.

• Disease Susceptibility: Different plants are susceptible to different diseases, complicating disease management.

• Harvesting Considerations: Differing harvest times can complicate maintenance and accessibility.

Practical Solutions

• Separate Zones: Plant each species in separate garden zones tailored to their specific needs.

• Container Gardening: Use containers to control soil and watering conditions for each plant, allowing them to coexist in proximity.

Planting Tips & Best Practices

• Optimal Spacing: Ensure adequate spacing to prevent overcrowding and competition.

• Timing: Plant according to each species’ ideal growing season; kale in early spring, lavender and blueberries after the last frost.

• Container vs. Garden Bed: Use containers for lavender to control soil alkalinity and drainage, while keeping kale and blueberries in acidic beds.

• Soil Preparation: Amend soil based on specific plant needs, using sulfur to acidify blueberry soil and lime to alkalize lavender soil.

• Additional Companions: Consider other companion plants like marigolds with kale or thyme with lavender.
