Ken, I grow them in Summer like a warm growing tropical plant, lots of water and fertilizer, but excellent drainage, best in full sun.
Comes Fall, I like to give them still a warm sunny/bright spot and since they start dropping leaves, indicating that they want a rest, I water very very sparingly during the indoor season, or you might rot the roots. Right now I gently increase watering as they want to start growing and blooming.
If you stop watering completely during the Winter inside, you will surely lose too many functional roots.
Once you have a young plant growing happily and they start to show a nice fat caudex when repotting, people usually raise the caudex above the soil line for interest.
