Christmas Cactus – Buds Often Dying

Q: Why do the immature buds of a blooming Christmas cactus often dry up and fall off?

A: In my observation, it’s most often caused by low humidity or by the plant being near a furnace vent. Move your plant now and consider putting it outdoors in a bright shady spot for the summer. Bring it in when night temperatures are in the 40’s next fall and keep it near a sunny window away from drafts.
