About two weeks ago, I received a beautiful Christmas Cactus in full bloom. Most of the blossoms have fallen off; how to I care for this plant? How often will it bloom? I live in California (Marin County, north of SF) and the plant is presently indoors in temperature ranging from 60-72 degrees. It receives indirect bright sunlight in the morning. Help! The plant is beautiful and I want to keep it.
Thank you.

My boyfriend moved here in November bringing his Christma Cactus with him. The problem his mother had left it outside and it had been frost bitten. It was very wilted but yet still bloomed. I am trying to bring back the fullest of the plant and it is just not responding. I am not sure what to do with it. Any help will be helpful. Thanks.
