Can You Plant Beans, Radishes, and Calendula Together?

Companion planting is a popular gardening technique that involves growing different plants together to enhance growth, deter pests, and improve yield. Gardeners often consider the compatibility of beans, radishes, and calendula due to their diverse benefits. In this article, you’ll learn whether these plants can thrive together and how to make the most of their companionship.

Compatibility Analysis

Yes, you can plant beans, radishes, and calendula together. These plants complement each other well due to their compatible growth requirements and mutual benefits. Beans, being nitrogen-fixers, enrich the soil, providing essential nutrients for radishes and calendula. Radishes mature quickly, helping to break up the soil, which benefits the root systems of beans and calendula. Calendula, with its pest-repellent properties, acts as a natural deterrent for harmful insects, protecting the other plants. These factors make them excellent companions in a vegetable garden.

Key Factors
