Hi All, My Christmas cactus used to be a happy bloomer and a fast grower, but it has not bloomed in two years and it is now completely pink all the time (see photo), whereas its mother plant back at my in-laws is bright green. It is clearly still alive (produced one pathetic bud last winter that failed to open), but it's not doing well. I have some suspicions as to what may have gone wrong. The problems started after I repotted it into a bigger pot (but it's been over two years! get over it already!). It was also cold on that window sill a couple of times (but I moved it and it was months ago, and the problems predate that episode!). So my question is two-fold: 1) what am I doing wrong? 2) what should I do now to revive it? Many thanks in advance.
