Q.My Christmas Cactus quit blooming about 3 years ago when we repotted it. It used to bloom every year before this. Any suggestions?
My mother’s Christmas cactus has bloomed without fail for years until she repotted it in a larger pot. (New pot was at least twice as big as old pot). She has never put the plant in the dark at any time. Should I repot again in a smaller pot? Anything else I can do to help it bloom? As my mother recently passed away at age 90, I would love to get her favorite plant to bloom again. Thank you

They prefer their roots to be crowded to bloom, so moving to a larger pot would have stopped the blooming. When changing pots, it's best only to go up one or two sizes. A too-large-pot can also cause root rot from too much moisture. I would put it in a pot that is only slightly larger than the rootball.
