Can You Plant Broccoli, Sweet Potatoes, and Lavender Together?

Companion planting is a strategy many gardeners use to optimize their garden’s health and productivity. By carefully selecting plants that benefit each other, gardeners can enhance growth, deter pests, and improve soil health. In this article, we’ll explore whether broccoli, sweet potatoes, and lavender can be planted together, examining their compatibility and offering practical advice for success.
