Question
Hello, I have a question regarding a wilting orchid flower on a stem...only it's the top flower on the flower stem, not the closest to the stem. From reading, that seems to be backwards from a normal wilt. They have been fine since June, when I got it. I am concerned about the light but I don't believe I have overwatered them, but it's possible. Have you ever seen this condition and know what I can do to save the rest of the flowers? There are two flower stems with about 5-7 flowers on each.  

Answer
Lynn, it is difficult to know the cause for certain, but, since it has been in flower since June, it is likely that this is a normal cessation to flowering rather than flower senescence.  As you mentioned, normally, the first flower to open is the first to drop.  Your plant is probably finishing its flowering phase.  This allows the plant to put its energy into new roots and leaves rather than flowers.  When flowering has finished, you should repot your plant to provide the best conditions for growth of new roots and leaves.  At the time of repotting, you will be able to examine the condition of the roots.  Healthy roots are firm and turn green when wet.  Any mushy roots are dead and need to be removed prior to repotting.
