Hi Gabe100
here is a link from the garden helper..
http://www.thegardenhelper.com/rubberplant.htmI had a rubber tree for 4 years in the same pot,, If the water is running right thru it it could mean that the soil is soooooooo dry it does hold water,, IF that is the case Water it until the water stops draining then you know you have enough water,,
Transplanting with new soil shouldn't be a problem,, I just transplanted mine a few weeks ago I used 1/2
cactus and
succulent mix,, with 1/2 regular potting soil . And it's doing fine,
I take mine outside every
spring thru fall ~ morning sun afternoon shade Because it's so hot here in Tx it wouldn't handle the afternoon sun.
Every time I take it outside I lose a few leaves,, as well as bringing it in for the winter.
Mine got over 7 foot tall,, 2 years ago I cut the top off and put the cutting right back into the soil and it took root ,
A few weeks ago it was over 8 ft tall I cut off two stocks at the top . repotted it and put the cut stocks back into the soil and they and the entire plant is doing fine,,
I would Propose IF you feel the soil has gone 'bad" go ahead and repot it using the 1/2 and 1/2 mix as mentioned above,
spring is a good time to do that,,!
