Hi again.
Here is pretty much my schedule for my CC/TC/HC or whatever you want to call the Zygocactus or Schlumbergera.
January - Still flowering
Feb. and March - resting ( 60-70 deg. very little watering) Can be cooler if you have a place to put them. Begin to take cuttings end of Feb.
April and May. Begin to water thoroughly when they are dry.
June to August - Put some outside in shade or partly shade...not full sun .
Sept. to Oct. Reduce daylight hours because buds are getting ready to form. Keep on the dry side and cool until the buds form, then increase the water and the temperature.
Hope this helps you get on a schedule that makes your plants happy.
