I've got a Sunrise cactus that I bought at the store, which came with instructions to give it cold temperatures (40 degrees) in November and December in order to have it bloom a few weeks later. I also have a few Christmas cacti that were given to me and I'm not sure when their bloom time is. Should I put them in the cold along with the Sunrise cactus, or leave them inside where it's warm and hope they bloom?
