Some times they do that. I have one doing the same thing.

I bought a Christmas cactus at Home Depot after Christmas years ago in a 4" pot very cheap. We bought a house with a sunroom dec 2017. It has bloomed pretty much nonstop since then. Except for August September. This picture was taken minutes ago. The most blooms it's had so far.

Oh my gosh thats a lot of flowers. Schlumbergeras do all sorts of funny things.

Karen, I guess the buds will fall off, I move it when its watered :(

If you have to move it, put a piece of tape on one side of the pot & move it, keeping the same side facing out or facing the sun, but try to keep its orientation to the light the same, & perhaps you'll lose less buds.

Once the buds are over an inch long it matters less, but while they're developing, they're very vulnerable to that, sorry.

Flowers take a lot of energy out of the plant. My cactus sat for years doing nothing. This year it hasn't stopped yet. There's more buds forming as we speak. Who knows why.

I can say this. For being a cactus, once in bud, if given a chance to dry out, it will shed it's buds. Got to keep moist but if you over water it, then it rots. Go figure.

Red and yellow circles: buds

Back boxes: new leaves

Just a small cutting, and it has buds. Nothing special done to/with the plant. I have bigger and older plants with no buds. Perhaps later? TC blooms at variable times for me.
