When bush beans are planted with potatoes, they will protect them from the Colorado potato beetle, one of the most destructive bugs that attack potatoes. This is a mutually beneficial relationship, as the potato, in turn, protects the beans from the Mexican bean beetle. |
Use Companion Plants to Naturally Control Pests
Companion plants excel at natural pest control.
Some companion plants help those around them by attracting insects that would typically attack the other plants, and some are attracted to trees and bushes that in turn attract birds that catch flying insects.
Sometimes two different plants are able to repel different unwanted insects from each other – so they work in harmony together. See the example at left about how bush beans and potatoes work together.
