Can You Plant Cabbage, Parsley, and Nasturtiums Together?

Companion planting is a time-honored gardening technique that involves strategically placing plants together to enhance growth, deter pests, and improve yields. Gardeners often wonder if cabbage, parsley, and nasturtiums can be grown together effectively. In this article, we’ll explore their compatibility, benefits, challenges, and best practices to ensure a thriving garden.

Compatibility Analysis

Yes, you can plant cabbage, parsley, and nasturtiums together. These plants complement each other in several ways, making them excellent companions. Cabbage, a member of the Brassica family, benefits from the pest-repelling properties of nasturtiums, which deter aphids and caterpillars. Parsley, an aromatic herb, can enhance the flavor of cabbage and attracts beneficial insects. The key factors contributing to their compatibility include their similar growth requirements and complementary pest control benefits.

Growth Requirements

• Cabbage: Thrives in cool weather with full sun exposure. Requires consistent moisture and well-drained, slightly acidic to neutral soil (pH 6.0-7.5).
• Parsley: Prefers full sun to partial shade and well-drained, rich soil with a pH of 6.0-7.0. It requires regular watering but does not tolerate waterlogged conditions.
• Nasturtiums: Enjoy full sun and well-drained, moderately fertile soil. They are drought-tolerant once established and prefer a soil pH of 6.1-7.8.

Benefits of Planting Together

Planting cabbage, parsley, and nasturtiums together offers numerous advantages:

• Pest Repellent Properties: Nasturtiums act as a trap crop for aphids and whiteflies, protecting cabbage. Parsley attracts beneficial insects like hoverflies, which prey on common garden pests.
• Improved Flavor and Growth: Parsley can enhance the taste of cabbage, while its presence may improve the overall health of the garden ecosystem.

• Pollinator Attraction: Nasturtiums attract pollinators, which can improve the biodiversity of your garden.

Potential Challenges

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

• Competition for Resources: Ensure adequate spacing to prevent competition for water and nutrients.
• Different Watering Needs: Nasturtiums require less water once established, so monitor soil moisture levels carefully.
• Disease Susceptibility: Cabbage is prone to clubroot; ensure proper crop rotation and soil management to prevent disease.
• Harvesting Considerations: Stagger planting times to manage harvests efficiently and avoid overcrowding.

Practical Solutions

• Use mulch to retain soil moisture and suppress weeds.
• Practice crop rotation to minimize disease risk.
• Regularly monitor plants for signs of stress or disease.

Planting Tips & Best Practices

• Optimal Spacing: Plant cabbage 12-24 inches apart, parsley 6-12 inches apart, and nasturtiums 10-12 inches apart.
• When to Plant: Start cabbage in early spring or late summer, parsley in spring, and nasturtiums after the last frost.
• Container vs. Garden Bed: All three can thrive in containers with adequate space and drainage.
• Soil Preparation: Enrich soil with compost to improve fertility and drainage.
• Additional Companions: Consider adding marigolds or dill, which also pair well with cabbage and parsley.
