Question

rhododendron
I have a rhododendron that has light green spots all over the leaves but the leaves don't turn brown. I can't find anything like it on the net. Can you tell me what I'm dealing with?

Answer
Hi Mandy,
Thanx for your question.  It looks like Azalea Lacebug damage.  See link to Oregon State University

The links at Oregon State will lead you to effective biological and cultural control of the pest.

I hope this helps.
Tom
