Why is the vegetation a fence problem?
Penn State Extension recommends regularly clearing weeds, grass and brush along and under fence lines, especially electric fences, to prevent shorts and maintain function. Alabama Cooperative Extension identifies weedy or overgrown electric-fence lines—especially moist green growth—as one condition that can reduce voltage.
For nonelectric woven wire, the immediate concern may instead be hidden damage, difficult access, vines or woody growth loading the fence. Write the observed condition without turning it into an unverified diagnosis.
