Thanks Michael, I will try that too, ours is definatly tall enough (It is about double my height)

I wouldn't say it has overtaken our garden, we don't have a garden it is just growing through the concrete. I swear it is trying to get me because i trimmed it.

My Partner has again contacted our managing agent today and added the links that have been given, so hopefully they might also do something. Once that has gone we can concentrate on rebuilding the wall. Yay!
