I find that phals that grow from the base of the "mother" are really
difficult to remove without
serious damage to both. My advice: get a bigger pot and leave them
together.

Thank you Ray,

It's also the nicest solution : the leaves of the 2 plants form a sort of
"pillow" and from the middle there come "mother's" flowers, but...I'm very
at the beginning and I'm still not really confident :-)
