Hi: The landscape in our community is primary native plants with mulch (no grass) covering the ground. It looks lovely for sure (and we feel good about preserving the natural environment) and my only concern is that there are these aggressive thorny vines that grow in the native brush. They can wind themselves around the bushes and kill them. So far, every time we visit I take my garden shears and cut them down, but I'd like to find a more permanent solution so I can spend those few hours of my vacation doing something else. Can anyone tell me what these vines are and how to get rid of them permanently (or at least nearly permanently)? Thanks.
