My boyfriend bought me this poinsettia from a good seller back at the start of December, but it has struggled ever since I got it. I’ve got lots of plants which are thriving and I don’t know what I need to do with this one as I’ve never had a poinsettia before, don’t want to give up on it but not sure if I should. It’s been in the window getting as many hours of indirect light as possible (there’s no good space for a grow light for it). My flat is very cold but I have kept it in a room which stays between 15-18° which I thought would be okay. Any advice is welcome! Was thinking when it’s a bit warmer I could repot it to a smaller pot and ensure all the roots are healthy but want to avoid while it’s still so cold. Before and after pics 😢
