Wow! That's cool! (you know it's my favorite!) Sometimes it is more fun to play(and leave it be) than mess with what appears to be a good thing (repotting).
How many growths is it?
If you end up needing an empty bonsai pot I have one I'd be happy to send you. I can measure but I think it is about 8" x 10-12" x 4" deep and rectangular.
I think mine bloomed for too long last year (April - February) and is now taking a break, though it has three growths that look ready to spike. Time will tell. I'll be curious to know how long yours blooms, Rick. You seem to have a knack for this one too.
