Forcing dormancy in your Christmas Cactus

The Christmas cactus, an easy and rewarding houseplant, can bring holiday cheer indoors once your outdoor gardens have been put to bed. You can force the Christmas cactus into a colorful bloom by starting the dormancy process about eight weeks before you would like it to produce flowers.  

In order to have your Christmas cactus on full display during the holiday season, start the dormancy cycle between the last week of October and the second week of November. To do this, cut back on moisture and reduce light and temperature. Only water the Christmas cactus when the soil feels dry, which is about an inch below the surface. Do not fertilize the cactus during this time. Ensure that the plant receives 12-14 hours of total darkness at night, indirect light during the day and average temperatures of 50-55 F.  One way to provide complete darkness for the 12 to 14 hours would be to cover the plant with a dark cloth or paper bag.

Once the cactus produces flower buds, it will then be time to move the Christmas cactus out of darkness to a bright window. Make sure your plant is not placed near any drafts or the cold will cause it to drop its buds. Expect your efforts to show a full display of flowers opening within a couple of week. Each flower will remain open for at least six or more days. Your Christmas cactus should remain in bloom for four to six weeks.
