Can You Plant Kale, Marigolds, and Dahlias Together?

Companion planting is a popular gardening technique that involves growing different plants together to enhance growth, deter pests, and maximize space. Kale, marigolds, and dahlias are three beloved plants, each offering unique benefits. In this article, we’ll explore whether these plants can thrive together in your garden, examining their compatibility, benefits, and challenges.

Compatibility Analysis
