I moved away for a year, and left my rubber tree with a friend - unfortunately I think the move shocked it, and it's now lost almost all of its leaves.
Do you have any tips on what I could do to revive it? Should I repot it?
I'd also recommend more light, but instead of cutting I'd recommend adding fertilizer sticks to the soil, about 3-4 of them. Thus they ensure a steady release of nutrients for a prolonged period of time. Cutting is not really necessary as once the plant starts growing it will sport new buds even on the barren stem where the leaves used to be. Just ensure it gets enough light.
