Flowering is related to the length of light during the day and night temperatures. The temperature range for flower bud development is between 50-60°F for a period of at least six weeks. The plant will need at least 12 hours of total darkness each night for 8-10 weeks or until you start to see buds form. Usually a closet, basement or garage is a good location, and the plant can be covered with a dark sheet of cloth. For holiday blooms, this needs to be done in late September to mid-October.

When buds have formed, bring plant out and put it in a bright indirect light location, keep soil moist, but not too wet. You will need to fertilize once a month with a water soluble fertilizer.

To get this Cactus to bloom for next Christmas it is important to cut the roots back for the new plants. When cutting this plant you should cut back to the second joint of each tip. Use these cuttings and place them in a moist peat and perlite mix or moist perlite. You should keep these cuttings damp but not too wet or they will rot. Once the cuttings have rooted, re-pot them with a good soil mixture and enjoy for next year!
