Can You Plant Cabbage, Kale, and Geraniums Together?

Companion planting is a popular gardening technique where different plants are grown together to enhance growth, deter pests, or improve flavor. In this article, we’ll explore whether cabbage, kale, and geraniums make good companions in the garden. You’ll learn about their compatibility, growing requirements, benefits, challenges, and best practices for planting them together.

Compatibility Analysis

Can you plant cabbage, kale, and geraniums together? Yes, you can! These plants can coexist harmoniously, though understanding their individual needs is crucial for success. Cabbage and kale, both members of the Brassica family, share similar growth requirements, making them natural companions. Geraniums, while different, offer pest-repellent properties that benefit their leafy neighbors.

Growth Requirements

• Cabbage and Kale: Both thrive in full sun and prefer well-drained, fertile soil with a pH between 6.0 and 7.5. They require consistent moisture and are hardy in zones 3-9.
• Geraniums: Prefer full sun to partial shade and can tolerate a range of soil types but do best in well-drained soil with a pH of 6.0-6.5. They are drought-tolerant once established and hardy in zones 9-11.

Pest Control and Nutrient Needs

Geraniums are known to repel common cabbage pests like cabbage worms and aphids, providing a natural defense for cabbage and kale. All three plants benefit from nutrient-rich soil, though geraniums require less nitrogen than their leafy companions.

Benefits of Planting Together

Planting cabbage, kale, and geraniums together offers several advantages:

• Pest Repellent Properties: Geraniums help deter pests that typically target cabbage and kale.
• Improved Growth: The different root structures of these plants reduce competition for nutrients.
• Space Efficiency: Their varied growth habits allow for efficient use of garden space.
• Soil Health Benefits: Diverse plantings can lead to healthier soil by promoting biodiversity.

Potential Challenges

While these plants can grow together, there are challenges to consider:

• Resource Competition: Cabbage and kale have similar nutrient needs, which could lead to competition if soil fertility is not maintained.
• Watering Needs: Geraniums are more drought-tolerant, so careful watering is needed to satisfy all plants.
• Disease Susceptibility: Brassicas are prone to diseases like clubroot, which could affect kale and cabbage if not managed.
• Practical Solutions: Regular soil amendments, careful watering, and crop rotation can mitigate these challenges.

Planting Tips & Best Practices

• Optimal Spacing: Ensure at least 12 inches between cabbage and kale, and 12-24 inches for geraniums to allow for airflow and growth.
• Timing: Plant cabbage and kale in early spring or fall, while geraniums are best planted after the last frost.
• Container vs. Garden Bed: Use containers for geraniums if garden space is limited, ensuring good drainage.
• Soil Preparation: Enrich soil with compost or well-rotted manure to support nutrient needs.
• Additional Companions: Consider adding herbs like dill or onions to further deter pests and enhance growth.
