Just for everyone's information, there are significant differences between the so called Christmas cacti and Easter/Thanksgiving cacti. None of them are true cacti, but share similar requirements. However, I digress.....in reference to getting them to bloom, it is important to know exactly what kind of plant you have to properly encourage them to bloom. Most people will have plants that were greenhouse grown for the retail market, and often sold at a time of year not in sync with what kind of "cactus" they really are. The bloom time of the various types coincides with the spring and fall equinoxes (Easter and Thanksgiving cactus), or with the summer and winter solstices (Christmas cactus). Expecting any one type to bloom at an inappropriate time of year is both frustrating, and next to impossible, since the bloom time is genetically programmed into the plant you have. Hope this helps!
