Ivy Garland

My neighbour is a bit of a tidy freak, if any plant on my side of the wall reaches the top and pokes over his side he cuts it off, hence my huge ivy garland which is hanging on by a few tendrils.
It looks quite good but I can't imagine its going to hang on for much longer.
 I grow ivy for its berries to provide food for the birds and for shelter for insects and birds.
I am now trying to encourage it to grow in the opposite direction away from his clippers, it will be sad though when this falls down, its about five years of growth and won't do the plants underneath much good when it collapses. I will however have loads of tangled ivy branches to play with.
