Janapese Bittersweet and other invasives
Japanese bittersweet is an invasive species. First, report it to your local county extension service and/or master garden program. They may send someone out to take a look and recommend a solution. The way to get rid of invasive plants is by a combination of digging them and poisoning them with glyphosate, the active ingredient in Round-Up.
