Question
I'm having problems with this plant.  The leaves on my coast leucothoe are dying back starting at the tip.  On the leaves a distinct purple border is next to the brown dead tissue and the green tissue.  Have any suggestions what it is?  I could send pictures if that would help


Answer
The problem could be either sunburn or a fungus.  If the plant is in medium direct sunlight I would eliminate too much sun as the cause.  Look at the leaf tip carefully.  If you can see any little brown or black dots in the brown tissue, then I would say it is a fungal disease.  Please respond back with your observations and I will make a recommendation for treatment.  Pictures would help.  Please send to [email protected].   Thanks.
