I've almost killed off all of my Phal. equestris aurea and my Dtps. Liu's Berry's roots!
They've been looking very sad lately and today I finally worked up the courage and pulled them out of their pots; the aurea's old roots are all dead, I think I've kept it too dry (it was planted in sphagnum when I got it, but I moved it to a bark/sphagnum/perlite mix and it seems it didn't take the transition too well) in its new medium, but the good news are that it's getting plenty of new growths on some of the old roots as well as new roots, the bad news is that they're insufficient to support the plant at the moment.
The Dtps. Liu's Berry's root system was almost completely rotted, so apparently I've been keeping this guy too wet. It barely has any roots left at all, but it has some aerial ones I hope can work as new roots until it has grown some more (it's working on some new ones, but they're a bit too small yet).
They're both taking a Superthrive soak at the moment and will be planted into smaller pots afterwards (due to their root systems having shrunk), kept away from too strong light, and standing warm and humid and being monitored carefully.
I really hope they'll make it, the aurea will I think since it's so vigorous, but I might have killed the little Berry...
