How should I care for a philanopsis orchid.It has 2 small white flowers which are whithered. Also what do I do with the roots which are outside the pot. It is only a fairly small plant that was given to me and is still in a clear plastic pot inside a ceramic pot.the leaves look fairly healthy.What should I be doing for it at this time of year. I have it inside in a southside room where it gets plenty of light but a short period of morning sun.
