Question
Our Skip Laurel bushes are developing brown and dying leaves

Answer
Elliot:
Lets start here. Can you send a photo of your plant? A photo can be useful to try to pinpoint a cause

Couple of questions.  How long has it been planted?  Were the leaves browning around their edges first?  When did you first notice this problem?  Examine the base of the affected plant(s). Do you see any evidence of physical damage/injury to the main stem near the base of the plant? Any spots on the leaves or are they just browing up?

Regards
Steve
