So I mounted 2 of my phals a few months ago on cork barks. They were in moss before and was doing fine with the care I was giving them. I thought mounting them would be better...but after 3 months, I was forced to rethink.
No matter how much I water them, they were drying out. The leaves and roots were growing but look like they are losing moisture. I added some moss to the bark, no help at all! My other orchids (which are in bark and moss), are doing better. Mounting was just slowly dehydrating these 2. The leaves don't have any moisture in them, they have come dry and thin! The plants also lost a few leaves each. The roots are starting to get brown and woody, instead of plump and green, the way they were before. So I took them off the mounts and repotted them in their old plastic pots (good thing I don't throw things away) with some moss..they seem to need a lot of moisture. I hope I'll be able to bring these plants back.
