I planted this hedge about 2 years ago. Growth fantastic. Towards end of last year 3 plants started to fade and I replaced them and they are doing brilliantly. However the one next to them has now faded, (leaves dying off and branches discoloured). Any idea what may be causing this and is there a cure.
There is no cure. Re-plant lost plants, Laurel is more resistant.
It is possible that the problem was caused by some other root-rotting disease but same results.
