Can You Plant Garlic, Radishes, and Calendula Together?

Companion planting is a popular gardening strategy where certain plants are grown together to enhance growth, deter pests, and maximize space. Garlic, radishes, and calendula are often considered for this practice. In this article, we’ll explore their compatibility and offer practical advice on planting them together.

Compatibility Analysis

YES, you can plant garlic, radishes, and calendula together. These plants complement each other well due to their differing growth habits and beneficial interactions. Garlic acts as a natural pest deterrent, while radishes grow quickly and help aerate the soil. Calendula attracts pollinators and beneficial insects, enhancing the garden’s ecosystem. Their compatibility is rooted in their growth requirements, pest control benefits, and nutrient needs.

Key Factors for Compatibility

• Growth Requirements: Garlic prefers a long growing season, radishes are fast-growing, and calendula can thrive in various conditions.
• Pest Control: Garlic repels aphids and other pests, while calendula attracts beneficial insects like ladybugs.
• Nutrient Needs: All three plants have moderate nutrient requirements and can coexist without depleting the soil.
• Spacing: Radishes can be planted between garlic rows, and calendula can be interspersed to fill gaps and attract pollinators.

Benefits of Planting Together

• Pest Repellent Properties: Garlic deters pests, reducing the need for chemical interventions.
• Improved Growth: Calendula attracts pollinators, enhancing the growth of nearby plants.
• Space Efficiency: Radishes’ quick growth allows for multiple harvests before garlic matures.
• Soil Health: Radishes break up soil, improving aeration and drainage.
• Pollinator Attraction: Calendula’s flowers draw bees and butterflies, promoting biodiversity.

Potential Challenges

While these plants can thrive together, certain challenges may arise:

• Competition for Resources: Ensure adequate spacing to prevent competition for sunlight and nutrients.
• Watering Needs: While all three have moderate water needs, monitor soil moisture to avoid overwatering.
• Disease Susceptibility: Rotate crops annually to prevent soil-borne diseases.
• Harvesting Considerations: Harvest radishes before they interfere with garlic’s growth.

Solutions

• Adequate Spacing: Follow recommended spacing guidelines to minimize competition.
• Consistent Watering: Use a drip irrigation system to provide even moisture.
• Crop Rotation: Rotate crops to maintain soil health and reduce disease risk.

Planting Tips & Best Practices

• Optimal Spacing: Plant garlic 6 inches apart, radishes 1-2 inches apart, and calendula 12 inches apart.
• Timing: Plant garlic in the fall, radishes in early spring, and calendula in late spring.
• Container vs. Garden Bed: Use raised beds for better drainage; containers are suitable for smaller gardens.
• Soil Preparation: Enrich soil with compost before planting to ensure nutrient availability.
• Additional Companions: Consider adding onions or carrots, which also pair well with these plants.
