Mounted DENB has yellowing leaves
I decided to try a mounted Orchid a couple of weeks ago. My Denb had bloomed this pas late Winter. I attached it to a bark and all seemed well. I left the roots exposed cause of the heat of the day and the humid conditions we have been getting. I have it outside my porch in a bright light with morning son for about a half hour. The roots being exposed, I assumed that i had to spray them not only daily, but 3 times or so...plus douse it with water and fertilized weekly. At the beginning i had 1 leave yellowing , but today i saw 2 more for a total of 3. I suspect that i am over watering it with spraying. I did cover the roots with transparent plastic wrap, perhaps the roots cannot be exposed?
