How do I remove trumpet vines stuck to the house without damaging the house or leaving suckers behind?
Removing Trumpet Vines
Cut the stems at the base to kill the top growth and let the leaves and suckers (aerial rootlets) wither completely before pulling down the vine. This does not kill the plant, by the way. If this is on brick, use a stiff nylon brush to remove what is left behind. Otherwise try a paint scraper with a gentle touch or 000 steel wool. Here is a link to a very thorough, if not disheartening, method for removing every last bit. https://www.joneakes.com/jons-fixit-database/1719-Removing-climbing-vines-from-walls. Another website suggests using something like Kilz stainblocker paint to hide residual marks. Good luck.
