We had a customer who had Ivy growing up and into her siding. 2/3 of it was covering her brick foundation, Ivy obviously is very difficult to remove if pulling so one of my guys said lets try this....small flat head spade shovel, it just peeled off like butter with no extra clean up. The Ivy that was growing into the siding just simply pulled out with hardley any effort. Just in case someone else runs into a job where they have to remove Ivy from a building. However I would'nt rec. doing this on any type of siding, just brick.
