The new, minimal watering schedule will force your Christmas cactus into dormancy, which is critical for getting the plant to bloom (and rebloom). This is where being a lazy houseplant gardener works to your advantage!
As a short-day plant, Christmas cactus needs 12 to 24 hours of darkness every day to enter a flowering period.
The ideal temperature for Christmas cactus to bloom is 50°F to 55°F, and the room has to be free of cold drafts and hot drafts.
The bloom this time around is much more sporadic and won’t be nearly as big as the holiday extravaganza you got, but it’s beautiful nonetheless and should last at least a month or so to take you through the rest of winter.
Once the flowers appear, gradually increase watering as you go back to your normal care routine. The amount of moisture required will depend on temperature, humidity levels, lighting conditions, container size, and the mix your plant is potted in.
