We have knock-out roses that are being overgrown by this weed-vine. It is very invasive and LOVES all this rain we've been having. The vines are easily snapped when pulled although we try to get to the roots. These are so intertwined that it's very tough to find the roots to spray a pesticide amidst the thorny rose bushes. The pictures show a 3 week growth since we have been busy the last 3 weekends. The roses and weeds are growing on a hill facing full sun. HELP!!!

Your vine is bindweed. It can be difficult to control. It spreads by seed as well as an extensive root system. It may take several attempts with pulling and herbicide treatment to eradicate it. See the following publication for more information. LW http://www.unce.unr.edu/publications/files/nr/2004/FS0448.pdf
