Hi

I promised to post some pictures of my browning holly bush.........:

its' been in the same spot for years without any problems. Now it's
going brown.

I need to do something about it, and it will obviously need cutting
back as the leaves to not look as if they can be saved.

My question is really what is wrong with it and when should I prune it
hard back?

TIA Jenny
