How do we get rid of potato vine for good?

We have potato vine that is outside our door and is out of control! How do we get rid of it for good? We've pulled it up and it still continues to come back!

How do we get rid of potato vine for good?
During the winter cut off all of the air potato vines at the ground. Pick up and get rid of any potatoes you can find. In the spring, when the vines begin to sprout, but before they get big, spray the plants with Roundup (glyphosate).

Reply:that means that there are many little potatoes under all that vine,I'm afraid you will have to dig deep to remove all of them.another thing you may want to try is cutting the plant to the ground then covering the aria with heavy black plastic,then maybe have a rock garden.
Reply:You just have to keep at it. Dig them up every time you see one shooting up. They die down in the winter. The recommended weedkiller is very expensive. Make sure you get rid of the little potatoes that form on the vine. I kept a plastic bag and a trowel handy, and everytime I went into the garden I checked for shoots, and dug them up. Some of the potatoes in the ground can get very big, others are tiny.
