Can You Plant Sweet Potatoes, Lemongrass, and Geraniums Together?

Companion planting is a popular gardening strategy where certain plants are grown together to enhance growth, deter pests, or improve flavor. Sweet potatoes, lemongrass, and geraniums are often considered for companion planting due to their unique characteristics. In this article, we’ll explore whether these three plants can be successfully grown together and provide practical tips for garden enthusiasts.
