Introduction: The Power of Companion Planting with Calendula

Calendula’s bright orange or yellow blooms and its ability to repel pests make it a valuable addition to any garden. As a companion plant, calendula not only enhances the beauty of your landscape but also improves the growing conditions for neighboring plants. Its natural compounds can deter aphids and other pests, while its ability to attract beneficial insects contributes to a balanced ecosystem. When paired with thoughtfully selected companion plants, calendula can help improve soil fertility, suppress weeds, and add continuous seasonal interest.

What Are Calendula Companion Plants?

Calendula companion plants are species that share similar growing conditions with calendula and offer additional benefits such as:

• Pest Deterrence: Some companions release strong scents or chemicals that repel pests, reinforcing calendula’s natural defenses.
• Soil Enrichment: Certain plants contribute organic matter or help improve soil structure, benefitting calendula and its neighbors.
• Pollinator Attraction: Flowering companions draw in bees and other pollinators, which support the overall health of the garden.
• Weed Suppression: Groundcover plants help reduce weed competition, ensuring that calendula has optimal access to nutrients and water.

By integrating these companion plants, you can enhance calendula’s performance while creating a more diverse and attractive garden.
