🌱 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.

These insects help control aphids and other pests naturally.
