mr. clarke had the most basic instructions for growing these; no matter what, whether or not it is flowering or not; if it has lost it's leaves, stop watering. you should stop watering definitely by beginning of january even if it has leaves or a flower spike. put it on a warm shelf with no water, doesn't need light, and when roots just start to poke out, put it into a new pot/media, use a stake to hold it up. when the roots are four inches long or just starting to poke out the bottom of a four inch pot, start watering and fertilizing, and you can give them a ton of light and fertilizer until the leaves fall off in the fall.
i've heard some say that they followed instructions and didn't water in winter and their plants shriveled up and died; it may be that if you don't water but still have some decent humidity it might help them to not dry out completely, but he said that you shouldn't have a problem if you just water and feed the heck out of it once you get some long roots
