Gardening is a labor of love, but pests can quickly turn your flourishing garden into a frustrating battlefield. One of the most effective and eco-friendly methods to protect your vegetables is trap cropping. This clever garden trick uses certain plants to attract pests away from your main crops, reducing damage and promoting healthier growth.
What is Trap Cropping?
Trap cropping is the practice of planting a specific plant that attracts pests more than your main crops. These “sacrificial” plants lure insects and other pests away, keeping your vegetables safe without heavy use of chemical pesticides.
Key Benefits of Trap Cropping
-
Reduces pest damage naturally
-
Minimizes the need for chemical pesticides
-
Encourages biodiversity in your garden

Supports organic gardening practices
How Trap Cropping Works
The principle is simple: pests are drawn to plants they prefer, leaving your primary crops undisturbed. By strategically placing trap crops, you create a protective barrier for your vegetables.
