Can You Plant Peppers, Mint, and Petunias Together?

Companion planting is a popular gardening technique that involves growing different plants together to enhance growth, deter pests, and maximize space. Gardeners often wonder about the compatibility of various plants, such as peppers, mint, and petunias. In this article, you’ll learn whether these plants can thrive together and how to make the most of their unique characteristics.

Compatibility Analysis
