One of the most frustrating things that can happen to Christmas cactus is
after the flower buds have developed they drop off the plant. Bud drop can
be caused by anyone of several different conditions. Usually it's because of
over-watering, lack of humidity or insufficient light. I got this from a
page for how to care for one.

and how do I keep its flower buds from dropping? The buds are the same
pink color of a typical "Christmas cactus", but quite a bit smaller.
