Can You Plant Eggplant and Rosemary Together?

Companion planting is a time-honored gardening practice that involves growing different plants together to enhance growth, flavor, or pest control. Eggplant and rosemary are two popular plants in vegetable and herb gardens, but can they be successfully grown side by side? In this article, we will explore their compatibility, benefits, challenges, and best practices to help you make the most of your garden space.
