🌿 Mint Companion Plants: Boosting Growth and Repelling Pests

Mint is one of the most effective companion plants in the garden. Its strong aroma helps repel pests, attract beneficial insects, and support healthier plant growth nearby. However, because mint spreads aggressively, it must be used carefully and deliberately to avoid problems.

This guide explains how to use mint as a companion plant, which plants benefit most, what to avoid, and how to keep mint under control.

🌱 Why Mint Is a Great Companion Plant

Mint provides several natural benefits in gardens and allotments:

• Repels aphids, ants, flea beetles, and cabbage moths
• Confuses pests with its strong scent
• Attracts pollinators and beneficial insects when flowering
• Helps improve biodiversity around crops

Because it spreads rapidly, mint works best when grown in containers placed near other plants.
