I am having to clean out a bed for this lady and it is covered with ivy/vines.... the kind that is mostly used for ground cover-up but since they have been neglected the past 10 years, they are just way out of control. How would you go about taking these up?? I tried by hand but that was a slow and vigorous process. Should you douse them with some chemicals to kill them and then pull them up or what?? ANY and ALL help is greatly appreciated. Thanks!
