Why might a barrier perimeter application for weeds be recommended?

A barrier perimeter application for weeds is recommended primarily because weeds can harbor and attract pests. Many weeds create a conducive environment for various insects and diseases, which can then spread to nearby plants or crops. By implementing a barrier perimeter treatment, pest control professionals can effectively reduce the presence of those weeds and thereby minimize the potential for pests to inhabit the area. This proactive approach helps maintain garden health and productivity by eliminating competing plants that might serve as reservoirs for harmful organisms.

While preventing soil erosion, enhancing aesthetics, or improving biodiversity are positive aspects associated with plants in general, they do not specifically address the direct pest attraction aspect of weeds. This is precisely why the focus is on the link between weeds and pest management in this context.
