Can You Plant Sweet Potatoes, Strawberries, and Zinnias Together?

Companion planting is a popular gardening technique that involves growing different plants in close proximity to benefit each other. Gardeners often consider this method to enhance plant growth, deter pests, and maximize space. In this article, we will explore whether sweet potatoes, strawberries, and zinnias can be planted together, and what you need to know to make the most of your garden.
