On your phal orchid - If you haven’t tried it yet, take it out of the bark and completely rinse it off and inspect the center. Cut off anything dead or black. If it looks hopeful put in a new pot with new bark.
I will do that on the Phal that I’m trying to save for Mom. Now that you mention it, it IS really packed in there with moss; looks like it was a HUGE orchid at one point in time.
Time to see what’s going on in there! The roots along the outside are green and healthy, which made me believe it was worth saving.
This will be quite the accomplishment if I can pull it off! :)
