By the end, you’ll know if these plants can thrive side by side and how to make the most of your garden space.

Compatibility Analysis

The short answer is no, onions, mint, and peaches are not the best companions. Each has unique needs and characteristics that may not complement one another.

Benefits of Planting Together

While planting onions, mint, and peaches together is not ideal, certain pairings offer benefits:

• Onions and Mint: Mint repels pests like aphids and onion flies, protecting onions. Both can improve soil health with their root structures.
