Last year I brought two Christmas cacti plants and about 6 poinsettias. The poinsettias were a mix of red, multi colored bracts and one day neutral variety. Although I tried to get them all to survive indoors until past the frost date, only one did and the tag was long gone by May! The last remaining poinsettia was planted outdoors in a protected and mainly shady spot. When we were being threatened with a frost I hurriedly dug the thing up and plonked it into a pot. A few days later I did pot it properly.
So here we are in October and I know that poinsettias need to be conditioned to put out the flower and bracts, so I have started putting it into a cupboard off the study each night. According to my garden center it should be fine with just a week of conditioning but I am hedging on the side of caution and keeping it in the closet until I see a sign that it is putting out flowers. It still has a few weeks. Note that the blue bucket is just a temporary holding saucer that makes it easy to water, and carry back and forth to the closet. When the flowers start to form it will be a nice neat seasonal container to sit in.
The Christmas cactus is a different plant and I don’t think it needs conditioning, though if it doesn’t put out some sign of a flower it might just get the closet treatment too. Right now it is on the kitchen counter, so bright indirect light is what it gets, but some evening lights may be a problem. I just read that it does like long nights, so that will be a closet job too!
