I have a rubber tree that's probably 5-7 years old and that's been kept in the same smallish pot the entire time. I've trimmed the tree once. It is about 70cm/2ft tall. I don't have a bigger spot for it so I want to keep it small. It's been doing well until this winter.
About a month ago the tree began dropping its lower leaves. Some lost leaves yellowed, some not. The photo's about a week old, the bottom two leaves have also fallen since. Although it's cold near the window, it's not colder than last winter. I water it every couple of weeks, maybe I overdid it.
I'm not sure what I should do. Prune the top branches for more branches, and keep the "leg" as it is? Or trim the tree down to a few leaf nodes above soil?
Would it be possible to save the entire top with all its leaves, or is it too big to survive in water long enough to grow roots?
