Dog Strangling Vine

(Question)

I have been hearing about the invasiveness of this vine for some years. It is in all the parks and has now crept across Leslie along the trails and into my garden, so I pulled the shoots last year. I must not have gotten all the root as it has sprouted again, even more vigorously. Can you tell me how to remove this nasty vine for good, please?

Dog strangling vine, also known as Cynanchum rossicum, Vincetoxicum rossicum and swallow-wort, is a nasty invasive that is is difficult to get rid of.  Fortunately because it is common problem there is lots of information available.  Here is a link to the response to a previous Toronto Master Garden enquiry which sets out steps that  you can take to get rid of it, including a Toronto Botanical Garden video:

Work on different ways of dealing with the plant has been conducted by the Ottawa Field Naturalists in connection with Butterfly Meadow they are building which was invested withe the vine.  Here is a link to a posting on the plant and how to deal with it, including the results of of mowing, mulching and tilling and useful information on what should be done with the roots, stems, seeds etc. of the plant:
