My moth orchid (Phalaenopsis, Doritis, Doritaenopsis, etc) is crawling out of the pot. Do I need to repot?

&nbsp &nbsp to top &nbsp &nbsp &nbsp &nbsp &nbsp If the mix is not terribly broken down *and* there are healthy roots in the pot, probably not. Lots of orchids grow naturally on trees. They constantly send out roots to attach themselves and find nutrients and water. This looks weird and unruly, but is natural. Most bark mixes will last one to three years before the mix will need replaced. If the plant is not growing well, it's possible the roots in the pot are rotted, possibly due to decayed potting mix, in which case it is advisable to repot the plant.
