I have pretty much the same problem with these two Phals. The first is Be Tris x Star of Dixie, which I really don't want to lose because the flowers are amazing. I had neglected this plant, and I was cleaning it up tonite, cutting off all the dead roots and stuff when the stem snapped off.
Here is the result. First the bottom portion:
And now the top portion:
Now I'm pretty sure the bottom with the roots and crown can be salvaged (although I haven't had much luck saving Phals in this regard), but is there any hope for the top portion with the leaves? I ask this specifically because I have the same situation with what's left of my Malibu Heir 'Blue Ridge':
I've had this "potted" in sphag for the past 4 months or so probably, and it hasn't changed in appearance one bit. Is there any hope?
