Now you put it in low-medium light. Water it once a week and watch the new leaves and new roots come out
A humidity tray will help the overall health of the plant... It will probably start a new bloom spike a month or so after Christmas (maybe late Fall depending on the growth cycle of your particular Phal.)
Phals. are heavy feeders, so I fertilize mine every couple of weeks once they start to spike. You should see new blooms in 2-3 months depending on the light you give it
If you have any problems, let us know--Good luck & good growing...
