I recently was given a rubber tree that had been a staple at the lobby of my work. It was always in a south facing window, it has been there for quite a few years, and it is root bound. When I lifted the fake moss off of the top I found that there are 4 to 5 inches of roots with no dirt anywhere in sight. It obviously needs repotting but being that it is in a new home, how long should I wait? Do they grow well like that and should I leave it? My favorite spot for it is an east facing window, will it adjust okay? oh I also have heard to take a paper towel moistened with baby oil and rub it on the leaves, should I do this?
