We moved in the winter when the field was deserted but now it seems to be a magnet for hooded youth.
They come and play football which intimidates the children, so they don't want to go out there - they also leave rubbish, broken bottles, etc.
We have a 6ft standard fence but I'm increasingly understanding why both sides of us have very high trees/hedges.
What can I put there in order to a) block the view of said youth, b) discourage them from trying to climb into our garden if they lose their ball?
I've put in some blackthorn but these are still small, I think I need a fast growing, prickly sort of plant, combined with rotating barbed wire or something.
Any ideas or tips welcome
