Full Answer

  1. Trim the pampas grass

    Cut stalks to approximately 3 feet in height before the plant blooms. A single pampas grass plant produces up to 100,000 seeds and disperses them through the air, where they travel up to 20 miles before landing.

  2. Apply the herbicide

    Use an herbicide containing glyphosate, if allowable in the area where you live. Reduce overspray that kills other plants by applying it to new growth with a paintbrush. Products should kill the remaining growth within a couple of weeks. If you see new growth during this period, reapply the herbicide.

  3. Remove any plant material

    At this point, some homeowners choose to leave the roots and remaining grass to die and rot in the ground. Others choose to pull the grass and roots from the ground to prepare the area for planting. In areas where the authorities don't allow herbicide, pull the plants and place them in plastic bags for disposal. Work the soil to ensure you remove all the plant matter if aren't using herbicide.
