I've read online in several places that I can tell if my plant is salvageable by checking the rhizome, and that's about as far as the description goes. Is it just a matter of digging up the plant and having a look at the underside? They often seem to be buried quite deep in the pots that I buy. Anything I should avoid while trying to check it? How likely is the plant to go into shock from this process? I've killed enough plants so far that I don't want to kill a salvageable one in my attempts to determine the plant's level of damage.
Your plant should be dormant by now if you are in the Northern hemisphere, so shouldnt be exhibiting any problems. But in answer to your question if you remove the rhizome from your pot and wash off the substrate, a healthy plant would have a firm white rhizome with no signs of rot and a good healthy root system. And yes, you do run the risk of setting your plant back by this process but whilst dormant this will of course be lessened. As Lloyd suggests a picture before you dive in uprooting everything may help diagnose whether there is a problem or not.
