Some clones are more tolerant to repotting than others! Mine is quite grumpy, the person I bought the bulbs from told me that if I repotted it, it will refuse to flower for about two years!
The advice I got was to repot the plant and let it stay in the container even when it grew over the edge! It's possible to plant it in a bigger container if the container has got holes on the sides! Like a basket that physalis comes in - but bigger of course! If the holes are so big the pieces of bark falls out - put a small net on the oinside of the container! Then the plant can sit there for years.
Oh, and the pots/containers should be low and wide so the bulbs can spread out but still keep the size of the pot reasonably low.
