Can You Plant Beans, Eggplant, and Calendula Together?

Companion planting is a popular gardening strategy that involves growing different plants together to enhance growth, deter pests, and maximize space. Gardeners often wonder if beans, eggplant, and calendula can be planted together, given their unique characteristics. In this article, we will explore the compatibility of these plants and provide tips for successful companion planting.

Compatibility Analysis
