I live in a complex and my neighbours have let their english ivy go wild up the side of our unit. Now, it is creeping over to the front of our unit and growing into the window! I was wondering if this could possibly be harmful to the building? The outside walls are made of a sharp textured concrete material, and it is extremely difficult to rip the ivy off of it. The little bit that I do manage to rip down leaves an unsightly mess. I have to admit I'm starting to downright hate this plant, they have it growing on their fence on the other side of the building, and it is very fast to take over my rock garden. Reading about it just now, I understand it grows fast in the winter. Great... Is there an easier way to remove it from the walls? I'm trying not to care about the side of the building, I just want to get rid of the part that has grown to the front, and towards the windows. Thanks.
