Can You Plant Peas, Broccoli, and Calendula Together?

Companion planting is a popular gardening strategy where different plants are grown together to enhance growth, repel pests, and improve flavor. This article explores whether peas, broccoli, and calendula can be successfully planted together, providing insights into their compatibility, benefits, and potential challenges. Readers will learn how these plants interact and how to optimize their growth in a shared garden space.

Compatibility Analysis

Yes, peas, broccoli, and calendula can be planted together. These plants complement each other well in a garden setting. Peas are nitrogen-fixers, enriching the soil and benefiting nitrogen-loving plants like broccoli. Calendula, known for its pest-repellent properties, can protect peas and broccoli from common garden pests. However, it’s essential to consider their growth requirements and spacing to ensure optimal development.

Growth Requirements

• Peas thrive in cool weather and prefer full sun to partial shade. They need well-drained soil with a pH of 6.0 to 7.5. Peas are climbers, requiring support, and should be spaced about 2 inches apart.

• Broccoli also prefers cool weather and full sun. It requires fertile, well-drained soil with a pH of 6.0 to 7.0. Broccoli plants can grow quite large, needing about 18 inches of spacing.

• Calendula enjoys full sun and can tolerate partial shade. It prefers well-drained soil with a pH of 6.0 to 7.0 and should be spaced 12 inches apart.

Benefits of Planting Together

• Pest Repellent Properties: Calendula acts as a natural pest deterrent, protecting peas and broccoli from aphids and other insects.

• Improved Growth: Peas enrich the soil with nitrogen, benefiting the growth of broccoli.

• Space Efficiency: These plants have different growth habits, allowing for efficient use of vertical and horizontal space.

• Soil Health Benefits: The diverse root systems of these plants help maintain soil structure and fertility.

• Pollinator Attraction: Calendula attracts beneficial insects, promoting pollination and a healthy garden ecosystem.

Potential Challenges

• Competition for Resources: Ensure adequate spacing to prevent competition for sunlight and nutrients.

• Different Watering Needs: Monitor soil moisture to accommodate the moderate water needs of all three plants.

• Disease Susceptibility: Watch for common diseases such as powdery mildew, especially in humid conditions.

• Harvesting Considerations: Plan for staggered harvesting to avoid damage to neighboring plants.

• Solutions: Use mulching to retain soil moisture, and apply organic fertilizers to maintain nutrient levels.

Planting Tips & Best Practices

• Optimal Spacing: Maintain the recommended spacing to ensure each plant receives adequate light and nutrients.

• Timing: Plant peas early in spring, followed by broccoli and calendula, to take advantage of cooler temperatures.

• Container vs. Garden Bed: While garden beds are ideal, containers can work if space is limited, provided they are large enough to accommodate root growth.

• Soil Preparation: Enrich soil with compost before planting to enhance fertility and drainage.

• Additional Companions: Consider adding herbs like dill or basil, which also pair well with these plants.
