Can You Plant Cabbage, Kale, and Alyssum Together?

Companion planting is a popular technique among gardeners seeking to maximize their garden’s health and productivity. Cabbage, kale, and alyssum can be excellent companions, offering mutual benefits when planted together. This article explores their compatibility, growing requirements, benefits, potential challenges, and best practices for successful planting.

Compatibility Analysis

Yes, you can plant cabbage, kale, and alyssum together. These plants are not only compatible but also mutually beneficial. Cabbage and kale, both members of the Brassica family, share similar growth requirements and thrive in cool weather. Alyssum, a low-growing flowering plant, complements them by attracting beneficial insects and providing ground cover.

Growth Requirements

Cabbage and kale need full sun and well-drained soil with a pH between 6.0 and 7.5. Alyssum, while more flexible, also prefers full sun to partial shade and similar soil conditions. Their nutrient needs align, making them suitable companions. Additionally, alyssum’s ability to attract pollinators and beneficial insects helps control pests that commonly affect cabbage and kale.

Benefits of Planting Together

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

• Pest Control: Alyssum attracts beneficial insects like hoverflies, which prey on aphids and caterpillars, common pests of cabbage and kale.
• Improved Flavor and Growth: The presence of alyssum may enhance the growth of cabbage and kale due to its ability to attract pollinators and beneficial insects.
• Space Efficiency: Alyssum’s low growth habit allows it to fill in spaces between cabbage and kale, maximizing garden space.
• Soil Health: Alyssum’s root system helps improve soil structure and prevent erosion.
• Pollinator Attraction: Alyssum’s flowers attract pollinators, which can benefit other flowering plants in the garden.

Potential Challenges

While these plants can thrive together, there are potential challenges:

• Resource Competition: Cabbage and kale may compete for nutrients and water if planted too closely. Ensure adequate spacing to minimize competition.
• Watering Needs: Alyssum requires less water than cabbage and kale, so careful monitoring is needed to meet each plant’s needs.
• Disease Susceptibility: Brassicas are prone to diseases like clubroot. Rotate crops and practice good sanitation to prevent disease spread.
• Harvesting Considerations: Harvesting cabbage and kale can disturb alyssum if not done carefully. Plan your garden layout to allow easy access.

Planting Tips & Best Practices

• Optimal Spacing: Maintain proper spacing—18-24 inches for cabbage, 12-18 inches for kale, and 6-12 inches for alyssum.
• Timing: Plant in early spring or fall when temperatures are cooler.
• Container vs. Garden Bed: While garden beds are ideal, containers can work if space is limited. Ensure containers are large enough to accommodate root growth.
• Soil Preparation: Amend soil with compost to improve fertility and drainage.
• Additional Companions: Consider planting herbs like dill or chamomile, which also benefit cabbage and kale.
