Hello. I rescued this plant from certain death at Home Depot. I put it indoors and deadheaded and it bloomed and did well for about a month and 1/2. Now, it buds, and they die before blooming. It has 2 tiny new plants at the base you can see in the photos. I am not good at watering. Is it dying bc it's winter, how temp sensitive is it, is it root rot, how much should i water, should i repot, should i repot the new plants? It does have leaves that die w yellowing and brown spots, Idk how much that plays in to all of this. I love the plant. It's so cheerful! I'd love to save it if I can. Advise pls? Thank you
