Manual Removal of Pampas Grass

This is a labor-intensive task, which is why some people tend to shy away from this method. Nonetheless, this is a good way of killing pampas grass if they are still at a manageable size and if they are only in a small area.

  • To start with, be sure that you are wearing the right clothing, especially because the leaves are sharp and can hurt your skin.
  • If the pampas grass is tall, the first thing you have to do is to cut it down to three feet.
  • Once the grass is only three feet, clump it in your hand and jerk it until it becomes soft. When you feel that it is already soft, pull it out of the soil.
  • Make sure to remove the whole root crown. Also, dispose the grass properly. These are important to make sure that the pampas grass will no longer grow back on the same spot where you removed them.
