Use an herbicide that contains picloram to treat. Spray each individual goldenrod plant with the herbicide. Wet each plant thoroughly until the goldenrod is saturated, but not to the point where the herbicide drips. Allow one growing season to pass before mowing the area. Do not disturb the plants or try to remove them during this time.
