I was given a nice pointsettia plant last Christmas-I nursed it though the winter (in its pot), and planted it outside this spring. It is doing well, with lots of new growth-but it isn’t putting out red leaves-will it do so? Also, if I re-pot it 9before the cold weather comes) is it likely to survive?
In San Diego there are quite a few people who plant poinsettia plants outside. They are green most of the year then they get the red flowers around December. I see several of these plants in my neighborhood and they are just green short tree looking plants until around December when the red flowers show.
Poinsettias produce colored bracts in response to short day lengths. This will occur naturally in places warm enough for them to overwinter outdoors. Indoors, you’re supposed to seal them in a dark closet or other space for part of the day over a period of weeks in order to get bloom. If there’s even a small amount of light getting in, they won’t flower.
