Can You Plant Onions, Sweet Potatoes, and Figs Together?

Companion planting is a popular strategy among gardeners seeking to maximize space and improve plant health. This article explores whether onions, sweet potatoes, and figs can be grown together successfully. By the end, you’ll understand their compatibility and how to make the most of your garden space.

Compatibility Analysis

The short answer is NO, onions, sweet potatoes, and figs are not ideal companions. While they each have unique benefits, their differing growth requirements and resource needs make them unsuitable for close planting.

• Onions prefer well-drained soil and full sun, thriving in cooler weather.
• Sweet potatoes need warm soil, consistent moisture, and ample space to spread.
• Figs require a warm environment and can grow into large trees that overshadow other plants.

These differences in growth habits and environmental needs mean they compete for resources rather than complement each other.
