Can anyone please help. My box hedge is about 15 years old. Bern lightly pruned twice a year. Had always been healthy, over the last 2 weeks it has died.
It is kept on our boundary by a picket fence and our previous neighbours always allowed me to prune their side to keep it within our boundary.
New neighbours of just over a year do not allow this. It is their 2nd home and they are not there often. They leave one car in their drive when they are not in residence, right up to our fence so I can't access it at all. They appear to have cut it back on their side recently and the hedge dying has happened since then.
Any ideas? It is like this right through the hedge, which is made up of 5 plants. It's about 4 feet tall, in line with the top of our fence. No other plants are affected.
