It's roots are literally under my entire lawn, and who knows how far reaching, crisscrossing, some nearly an inch in diameter, and lengths in the hundreds of feet. I got it "visually" under control in the front of the property, though it decided to invade the back. I've discovered it's roots have punctured through other plants' roots/tubers, like the daylillies or peonies. IT MUST BE STOPPED!!!
Asiatic/Oriental Bittersweet is an invasive species and difficult to eradicate and control. We recommend that you speak to the manufacturer Dow AgroSciences for information on treating with Crossbow as it is not listed on the label. They can be reached at 800.992.5594. We also suggest speaking to a Master Gardener in your area by clicking the link below for more treatment advice. http://www.ahs.org/gardening-resources/master-gardeners
