Also, if the roots are exposed like the one I have, try moving up to more frequent water/fertilizer. I also have a fan blowing directly onto all the orchids 24/7 to assure the xposed roots dry out over night.
The roots are exposed, but they get soaked every morning with the misting, and the tree fern holds the moisture for the day and eventually dries out overnight. I heard they like it moist... Thanks for the tips!! Much appreciated.
