Photinia problems ...

Hi,

I have a total of six photinia trees in my front garden, all planted in a line along a fence. They were planted there two years ago, and up until recently have been doing fine. However, over the last few months one of them has taken a real turn for the worse, as can been seen in the photo.
Obviously it shares the exact same bed as the others, so it is unlikely to be environmental. Its leaves (what is left of them) do not look victim of anything fungal (they have simply been dropping off over time, with no fresh shoots to replace them). I can see no other signs of damage or specific disease.
To treat it I have pruned and added fertiliser, but with no effect. I am at a loss as to the cause and the remedy.
Any help would be much appreciated.
Many thanks in advance
