Your Christmas cactus plant bloomed abundantly in November or December, and now you’re wondering if you have to wait a whole year before it flowers again. The surprising answer is: Nope!
In October, start reducing the amount of water your plant normally receives. Lightly water the topmost layer of soil (just the first inch or so), and only when the soil feels completely dry to the touch.
In general, Christmas cactus should be watered every 10 days or so in winter, and every 7 days in summer (sometimes more often, if you live in a sunny, arid climate).
