My Christmas Cactus nearly always blooms between Thanksgiving and my birthday..he he he, Dec. 1. I figured it was because that was the time I moved it inside for good, and the cold weather had been around long enough to kick it into bloom time.....Mine is just starting to 'pink'. I love it! Now, I will move it into my house....but, what do you do with 25 house plants inside? Too many!
