I posted this question in the Succulent forum, but thought maybe someone here could answer as well.
Orchid Cactus question
The key to orchid cactus bloom is providing a winter rest period. From now until the end of January provide cool temps in the 50 to 55 degree range. Allow the potting mix to become quite dry between waterings - just enough to keep leaves from withering. Bright light is not so essential during this period.
In February or perhaps a bit earlier, you may see signs of new growth. Then it is time to increase the light to bright indirect and gradually increase the water and fertilizer frequency.
