Hi Jerry,
Sorry my website doesn't address your specific question, but Eric's has given a good answer. P. maculata needs much more warmth in winter than most other Pleiones. Like Eric, I keep the compost just a little damp at this stage. Some growers, despite the new leaf growth evident at the current time, keep their compost for maculata completley dry until spring and start watering around the same time as for their other Pleiones. I have tried both methods and oddly found that either seems to work quite well. But having a little moisture there for the new roots to seek out is my preference.
