Hi everyone! An excellent resource, for identifying and treating orchid pests, viruses, fungal, and bacterial diseases is published by the American Orchid Society.It's called "Orchid Pests and Diseases." Picked it up from my local orchid society for twelve dollars. I have found it to be more valuable than anything I've seen on the internet.
Some of my Ctsm orchid's leaves are sticky. When I rubbed them with water and my fingers. It seems like it comes off, but it comes back in a few weeks. What is this ?
