Benefits of Planting Together

• Pest Repellent Properties: Calendula and sunflowers help deter pests like aphids and beetles from beans, reducing the need for chemical pesticides.

• Improved Growth: Beans enrich the soil with nitrogen, benefiting sunflowers and calendula.

• Space Efficiency: Utilizing vertical space with sunflowers and beans allows calendula to spread at ground level.

• Soil Health Benefits: The nitrogen-fixing ability of beans improves soil fertility, promoting healthy growth for all three plants.

• Pollinator Attraction: Sunflowers and calendula attract pollinators, which can enhance bean production.

Potential Challenges

• Competition for Resources: Beans and sunflowers may compete for sunlight if not spaced properly. Ensure adequate spacing to prevent overshadowing.

• Different Watering Needs: While all three plants require moderate watering, sunflowers may need more water during flowering. Adjust watering schedules accordingly.

• Disease Susceptibility: Beans can be susceptible to fungal diseases, which may spread to calendula. Ensure good air circulation and avoid overhead watering.

• Harvesting Considerations: Harvesting beans can be challenging if they are entangled with sunflowers. Plant strategically to allow easy access.

Solutions: Use trellises for beans to prevent entanglement and ensure proper spacing to reduce competition.

Planting Tips & Best Practices

• Optimal Spacing: Plant beans 2-4 inches apart, sunflowers 12-18 inches apart, and calendula 12 inches apart to allow room for growth.

• Timing: Plant after the last frost when the soil has warmed. Beans and sunflowers can be sown directly, while calendula can be started indoors.

• Container vs. Garden Bed: While a garden bed is ideal, containers can work if they are large enough to accommodate the plants’ growth habits.

• Soil Preparation: Amend soil with compost to improve drainage and fertility before planting.

• Companion Plants: Consider adding marigolds or nasturtiums, which also pair well with these plants and offer additional pest control benefits.
