Buxus getting yellow - leafs die and fall down

have planted around 20 Box plants around April this year. It was growing fine since then, new leaves started appearing around May and I was happy with it.

I just came back from holidays and noticed that old leaves started to go yellow. Most of the plants seems to be affected.


I believe it was raining quite badly in scotland in last 2 weeks - could this be a problem?


I would appreciate any help.
