Can You Plant Cabbage, Nasturtiums, and Alyssum Together?

Companion planting is a popular gardening strategy that maximizes plant health and yields by pairing compatible species. This article explores whether cabbage, nasturtiums, and alyssum can be effectively grown together, detailing their compatibility and offering practical planting advice.

Compatibility Analysis

Yes, you can plant cabbage, nasturtiums, and alyssum together. These plants complement each other well in a garden setting for several reasons. Cabbage benefits from the pest-repelling properties of nasturtiums, which deter common pests like aphids and cabbage worms. Alyssum, on the other hand, attracts beneficial insects such as pollinators and predatory wasps, which help control pest populations.

Key Factors

• Growth Requirements: All three plants have similar needs in terms of sunlight and soil, making them compatible companions.
• Pest Control: Nasturtiums act as a trap crop, attracting pests away from cabbage, while alyssum invites beneficial insects, enhancing natural pest control.
• Nutrient Needs: These plants do not compete heavily for nutrients and can thrive together with proper soil management.
• Spacing: Adequate spacing ensures each plant has sufficient room to grow without competing for light or nutrients.

Growing Requirements Comparison Table

Benefits of Planting Together

• Pest Repellent Properties: Nasturtiums deter pests that commonly attack cabbage, while alyssum attracts beneficial insects.
• Improved Flavor and Growth: The presence of nasturtiums can enhance the flavor of cabbage.
• Space Efficiency: These plants can be interplanted to maximize garden space.
• Soil Health Benefits: Alyssum can help improve soil structure with its low, spreading habit, reducing erosion.
• Pollinator Attraction: Alyssum’s small flowers attract pollinators, which can benefit the entire garden ecosystem.

Potential Challenges

• Competition for Resources: While generally compatible, ensure proper spacing to avoid competition for light and nutrients.
• Different Watering Needs: Nasturtiums prefer slightly drier conditions, so monitor soil moisture to meet the needs of all plants.
• Disease Susceptibility: Overcrowding can lead to increased susceptibility to diseases like mildew.
• Harvesting Considerations: Plan your garden layout to allow easy access for harvesting cabbage without disturbing nasturtiums or alyssum.

Practical Solutions

• Use raised beds or containers to control soil moisture more effectively.
• Mulch around plants to retain soil moisture and suppress weeds.
• Regularly check for pests and diseases, taking swift action if needed.

Planting Tips & Best Practices

• Optimal Spacing: Ensure at least 18 inches between cabbage and other plants to prevent overcrowding.
• When to Plant: Start cabbage in early spring; sow nasturtiums and alyssum after the last frost.
• Container vs. Garden Bed: All three plants can be grown in containers, but ensure adequate size and drainage.
• Soil Preparation: Enrich soil with compost to provide nutrients and improve drainage.
• Additional Companions: Consider adding herbs like dill or chamomile, which also pair well with cabbage.
