seriouse ivy problem!
I have a whopper of what I can only describe as a ivy tree I need to kill. It's climbed up the back of my piggery wall and over goodness knows how many years totally covers the building. The stems are as big as my arm and wound togeather so on top of my roof is about a foot width combined stem. I can't cut it all at the base as I can't get to some of it. Is there a weedkiller that I can pour at the roots? I know ivy leaves are good at repelling spray. This is so massive its started collapsing the roof! Thanks.
