Abstract: A barrier system to be installed on a ground surface for keeping unwanted vegetation from growing across a boundary comprises a first end stake, a second end stake, a plurality of inner stakes, and a cover. Each stake includes generally horizontally-oriented cap and a generally vertically-oriented anchor attached to the cap. The cover includes a channel, a top wall, a first side wall attached to one side of the top wall, and a second side wall attached to the other side of the top wall. The first end stake is configured to be positioned in the channel at a first end of the cover, the second end stake is configured to be positioned in the channel at a second end of the cover, and the inner stakes are configured to be positioned in the channel in between the first end of the cover and the second end of the cover.
