Phaiocalanthe Kryptonite 'Chariot of Fire'

This orchid is easy to grow as well as floriferous.  Sadly, I neglected it.  What was my error?  I failed to repot it onto fresh media.  This has to be done to these plants where I live or they will deteriorate and stop blooming.  I replanted this orchid this year but its recuperation has been slow.  I expect it to start blooming again next year.
