I recently moved from Southern California to the Pacific Northwest and took all of my plants with me. They were extremely unhappy with the lack of sun in the winter up here but now they seem to be doing well with the longer days and plentiful sun. However, I seem to be killing the rubber tree I've had for over a year.
I have to admit that I haven't been the best caretaker. I water when I notice the leaves drooping (maybe once a week?), and I don't really pay attention to how much I water the plant. It's in a ceramic decorative pot, in the plastic pot it came in when I bought it, with a plastic tray under it. It's by the window but because of where it's situated, it doesn't get direct sun at all. I've never fertilized it.
I noticed that some of the leaves are yellowing, and upon closer inspection, the stems look blotchy and are wrinkled in some spots. I'm afraid I let the roots rot with bad watering, so now I've stopped watering it at all.
I've looked online but there are conflicting reasons as to what I could be doing wrong. Any advice for saving my plant and/or taking care of a rubber tree in general would be greatly appreciated. Thank you!
