red spots on red tip shrubs/trees
I have several red tips that are about 10 yrs old, planted in a row as a privacy hedge - I have noticed that 3 of them in the middle have lost 90% of their leaves - and there is red spots on the leaves - it looks like it is spreading to the others - please let me know what this is and what to do about it. debby pate

Several different fungi cause leaf spots on red tip (photinia). The problem is usually worst during wet, humid weather. It's usually not necessary to spray the shrubs because once the leaf spotting and defoliation is noticed, the weather conditions have usually changed and no new infections are occurring.
If the problem continues, you can spray with a protectant fungicide in early spring, just as leaves are unfolding, and continuing every two weeks until weather conditions improve.
