I have a problem that has been developing over the last several years. A vine has been crawling up a 20 foot brick wall in my garden. It has now reached the top and I am afraid that it's starting to grow down into my neighbor's yard on the other side of the wall. It is also slowly creeping to the apartment windows of other neighbors nearby (the lady on the third floor has already complained about insects).
I've tried to kill it by cutting the vines, thus separating the growth above from the roots below. But that has yielded no result.
I'm sorry but I don't know what type of vine it is (the kind that grows like crazy!).
So, any suggestions on how to kill it? Should I just buy a herbicide and spray all the leafs (20 feet high and a length of 10 feet)?
Via these links can you find photos of the vine and its branches which appear to have roots going up the length of the wall.
Finally, I live in Holland where the winter temperature is cold, but only drops below freeze point about 4 weeks a year. It is quite wet though.
Any suggestions would be welcome.
