Can You Plant Cabbage, Nasturtiums, and Geraniums Together? A Guide to Companion Planting

Companion planting is a time-honored gardening technique where certain plants are grown together to enhance growth, deter pests, and improve flavor. In this article, we’ll explore whether cabbage, nasturtiums, and geraniums can thrive together in your garden. You’ll learn about their compatibility, growing requirements, and the benefits and challenges of planting them together.

Compatibility Analysis

Yes, you can plant cabbage, nasturtiums, and geraniums together. These plants complement each other well, offering various benefits that make them excellent companions in the garden.

• Growth Requirements: Cabbage, nasturtiums, and geraniums all prefer similar sunlight conditions, though they vary slightly in water and soil needs.
• Pest Control: Nasturtiums are known for their ability to repel aphids and other pests that commonly attack cabbage. Geraniums can also deter certain insects, adding an extra layer of protection.
• Nutrient Needs: While cabbage is a heavy feeder, nasturtiums and geraniums have moderate nutrient requirements, reducing competition for resources.
• Spacing: Proper spacing ensures that each plant receives adequate sunlight and air circulation, minimizing disease risk.

Benefits of Planting Together

• Pest Repellent Properties: Nasturtiums act as a trap crop, attracting pests away from cabbage. Geraniums can repel beetles and other insects.
• Improved Growth: The presence of nasturtiums can enhance soil health by fixing nitrogen, which benefits cabbage growth.
• Space Efficiency: These plants have different growth habits, allowing them to fit well in the same space without overcrowding.
• Pollinator Attraction: Nasturtiums and geraniums attract pollinators, which can improve the overall health of your garden ecosystem.

Potential Challenges

• Competition for Resources: Cabbage’s heavy nutrient needs can lead to competition with nasturtiums and geraniums if not managed properly.
• Watering Needs: While nasturtiums prefer drier conditions, cabbage and geraniums require more consistent moisture.
• Disease Susceptibility: Close planting can increase humidity and the risk of fungal diseases. Ensure proper air circulation.
• Harvesting Considerations: Cabbage requires more space for harvesting, so plan your layout to allow easy access.

Solutions

• Use mulch to retain soil moisture and reduce competition.
• Water deeply but less frequently to accommodate all plants.
• Space plants adequately to ensure good air circulation.
• Rotate crops annually to prevent soil nutrient depletion and disease buildup.

Planting Tips & Best Practices

• Optimal Spacing: Ensure at least 12 inches between nasturtiums and geraniums, and 18-24 inches for cabbage.
• Timing: Plant seeds in early spring after the last frost, or start indoors and transplant.
• Container vs. Garden Bed: While garden beds offer more space, containers can control soil conditions better, especially for geraniums.
• Soil Preparation: Enrich soil with compost before planting to support cabbage’s nutrient needs.
• Additional Companions: Consider adding herbs like dill or chamomile, which also benefit cabbage.
