I have a Thanksgiving cactus and I've never done anything special for it and it blooms without fail every Thanksgiving. As a matter of fact it has blooms all over it right now. I've always considered it one of my no fuss plants and can't imagine going through all the gyrations everyone here does to get it to bloom.
Not only that, I have it in a SE facing window in full sun and that is the only window it likes. It has quadrupled in size since I put it there. When I had it in indirect light it just never did take off.
It has been moved all over the country, the pot dropped on the floor, overwatered, underwatered you name it and it just continues on without one complaint. It has never had a pest or disease, even when a heavily infected plant was right next to it (didn't see the problem for awhile).
I've often thought of getting rid of my other more picky plants and replacing them with holiday cactus, because I find them to be no work at all. I don't set temperatures back, no bag or closets, nothing. I'm amazed at the lengths people go to get there's to bloom. Sure glad mine likes being watered once a week and fertilized when I think about it.
Amen. And ditto (even the moving around the country and breaking the pot open on the floor).
I have five holiday cactus and have found the exact same results from benign (or perhaps not-so-benign) neglect. These plants live indoors year-round and are next to S or SW windows (~47degN latitude, Montana). They do get over-sunned in the summer if the sun isn't blocked in the afternoon (which is done to help keep the house cooler anyway).
I've also found that they don't mind being pot-bound and only re-pot them when absolutely necessary.
