Hi Leela! You have a wonderful Phal; she is definately worth the effort to save her! If you have leaves on your orchid you can save it. Follow Brooke's advice and try misting the leaves, undersides too, with Superthrive or worm tea a few times a day. Be sure to sop up any drops that fall into the crown; you don't want water to stay in this area. Keep the moss slightly moist and you will see new roots in no time.
Some growers will put a baggie over the entire plant to increase humidity. I find it encourages fungus and no longer use this method. Here is the link to the skewer method; it helps me tremendously. Good luck and keep us posted!
