Ivy can be a blessing or a curse, depending on whether you want it climbing up the outside walls of your house. Ivy needs to be maintained, as it can creep under window frames, into chimneys and throughout roof shingles. It can be difficult to remove ivies from stone walls, but it is possible with the proper equipment, patience and time.
Determine whether the ivy is alive or dead, as it is much more difficult to remove if it is dead and dry. Use a water hose on the spray setting to soften up the vines before pulling them away either way. If the ivy is dead, keep in mind that you will need to be as careful as possible when removing it so you have minimal scraping to do.
Pull the ivy away from the stone wall, starting up as high as the vines go and working on downwards.
Use a scraper to carefully scrape off any tendrils and suckers, which are usually the parts of the vine that stick onto the wall after the vines are pulled down. Work slowly and carefully, scraping at an angle to minimize any damage to the stone wall. Use a ladder if necessary to reach higher vines.
Use pruning shears to chop the ivy right at the ground root. Discard the vines in the trash or a compost pile.
Spray the roots with a solution designed to kill them permanently, such as Roundup or Brush-b-Gone.
