Hi,

Thank you for your question.

It appears to be Hedge bindweed (Calystegia sepium), although it is native to North America, it is invasive in 35 states, and is highly aggressive and hard to irradiate. 

It is important to understand how it spreads in  order to irradiate it. Hedge bindweed has   extensive, but shallow, rhizomatous root system. Root fragments as small as 1 inch in size are capable of regrowth. So when pulling if root fragments are left it will sprout again.  If you are attempting to hand pull you must be persistent in removing roots and continue over the course of more than one season to irradiate. The best way to eradicate a large infestation of bindweed is by applying glyphosate to the bindweed in fall when the bindweed is actively growing; however, spring treatment has the additional benefit of reducing seed production, vigor, and spread of the plant. Generally, additional applications need to be made when the bindweed regrows 

Since the plant is originating in your neighbors yard it may be difficult to implement any of these techniques unless you can convince them of how invasive a vine this is.  What you can do is  focus on trying to put in a rhizome barrier for containing runners so spreading roots from the pieces left on the neighbor's side don't keep rooting-into the your side, though wandering vine growth still could breach your fence.  You will need to constantly monitor the area.

Thank you for the precise description and solutions. I’m interested in installing a Rhizome Barrier. Can you guide me to guidance or resources for installing the barrier? 

Hi,

Although this UMD link with video is about Bamboo, it explains how to install a Rhizome Barrier. You will probably not have to be as extensive as this information suggests. It is important to dig down deep enough when installing the barrier,  so the barrier will be effective in keeping runners from running!
