Ask-a-Dave's-Gardener: Christmas/Thanksgiving Cactus Flower Question, 0 by MissionVao

Hey,

So, I put my Christmas cacti (which are probably Thanksgiving cacti...) in a window that I left barely cracked so they got a cool draft. They (three of them) produced buds after about two weeks, so I moved them away from the window to a place with more constant temperature. Now it seems all the buds have stopped growing. They've been the same size for maybe three weeks. They don't seem dry, though. I poked at them carefully to make sure they were still attached (I know sometimes they'll dry up and fall off if the plant gets unhappy), and they seem firm. The largest one even still has a noticeable healthy sheen, but it doesn't seem to grow. Is that normal? Should I do something to encourage it?

I've attached a picture of the largest flower bud. It's supposed to be "Dark Marie". The others are different (I think "Beach Dancer" and "Thor Vita", I think), but they also seemed to have stagnated.

I have since then put the plants back in the window... I don't know.
