how do i get rid of ivy on my walls
As figrat has said. Spray new growth with a glyphosate-based weedkiller as it appears. Allow the cut ivy to dry out on your walls until it is brown - three months or more - before pulling it off.
We have a beast on the side of our wall and the trunk at the base is about 10 inches thick at least! the problem is we have sparrows and thrush nesting in there so we need to wait for the chicks to leave
We've hacked out a chunk at the base which has slowed the growth big time and them we're going to cover the exposed bits with jays fluid in the hope it will kill off the root too... we've no other plants near by. and then finally we're going to have a bbq and invite all the friends and family around to help us pull it down!
