Thanks for your advice (again), Daisy. Can you decide from my photos that the new growths are roots or pseudobulbs/leaves? I'll remember your warning: "Zygo's are tricky to repot as the roots are easily broken and damaged." -- which is the very sad thing I will dread...
As for the Phal since it came with moss (all I can see is moss), I have a bit concern about how the roots inside doing... the orchid is not big and the cray pot is 4" which seems suitable.
