Answer: Phalaenopsis, or Moth Orchid, develops long flower sprays. If you cut a faded spray back to a node, a secondary spray may form. If you cut the stem down to the crown of the plant, no new flowers will form on that stem. I just leave part of an old stem on my plants so another set of flowers can develop from a dormant bud.
Phalaenopsis should be repotted only when growth slows and the plant is obviously potbound. Since orchids prefer moist soil, saturated bark shouldn't affect them. I would repot, using fresh potting mix, only when the plant has definitely outgrown its container.
