There’s no worse feeling for a gardener to see how the plant you’ve spent so much time and effort to grow has been completely destroyed by pests. Using pesticides or other strong control methods may not always be practical. If you’re looking for a natural way to keep pests at bay, your best bet is to try sacrificial plants. Many organic gardeners make use of a trap crop that essentially attracts harmful pests to keep them from attacking your beloved plants.

The logic of a sacrificial plant is quite simple. Even though pests will typically feed indiscriminately, they still have their own preferences and can be lured away from valuable plants that you wish to specifically protect. Trap cropping can be a useful organic technique for dealing with pests. You just need to find a suitable sacrificial plant that you will add near the important crop that you wish to keep safe from pesky insects.
