Can You Plant Eggplant, Sweet Potatoes, and Sage Together?

Companion planting is a popular gardening technique where different plants are grown together to benefit each other. Gardeners often wonder if eggplant, sweet potatoes, and sage can be combined successfully. In this article, you’ll learn about their compatibility, growing requirements, benefits, challenges, and best practices for planting them together.

Compatibility Analysis

YES, you can plant eggplant, sweet potatoes, and sage together, but with some considerations. Each of these plants has unique growth requirements, but they can complement each other in certain ways.

• Eggplant and sweet potatoes both thrive in warm conditions and require similar sunlight, making them good companions. Sweet potatoes can act as a ground cover, helping to retain soil moisture and suppress weeds around eggplants.
• Sage, an aromatic herb, can repel certain pests that might otherwise target eggplants, such as flea beetles. However, sage prefers slightly drier conditions compared to the other two, so careful management of watering is necessary.
