I just repotted mine into a coarser mix so I can water it more often without worrying. It is in 5 parts bark fines, 1 part perlite. It is about 2/3 that mix...but i mixed in some of the medium it was already in, and Im not really sure what that was.
It didnt mind the repot, even though I took it down to bare roots to switch out the medium. I was careful though.
Hopefully someday mine will be big and beautiful too :-D
