Hi: Glad you are having a nice winter so far. I keep my rubber tree in a smaller pot and on the dry side. I have repotted it once so far. However,the pot your plant is in must be too small if the roots are showing. It would probably be a good idea to repot. I put mine outside every summer and it seems to give it a head start to withstand the winters indoors. I have it in medium light. Peggy In Massachusetts P.S. we are also having a nice winter so far.
