I didn't want to hijack the other zz thread, so I posted this.
I keep reading/hearing from people about how easy a plant this is to care for. Not for me. It would seem from the threads I've read that over watering was the problem, but I tend to water them like a Xmas cactus. Not as much as a "regular" houseplant, but more than my true cacti.
This is what it looks like when the stems die back; parts of the stem are alive and healthy after the rest of it dies.
I admit, I'm totally stumped. Any advise would be appreciated.
