BLC severely pot-bound?

[boytjie]

New to the board. Hello, everyone! I have a BLC that I purchased from a nursery in Florida, and dragged all the way back to Upstate NY in my hand luggage. It's in a clay pot and is so pot-bound that the growing medium is fused to the roots in a solid mass, and nearly all of the external roots have attached themselves to the sides of the pot. Any hints on how to repot this puppy without killing it? Or... alternatively, could I just smash the pot, put the entire root mass into a larger pot, and put new medium around it? Thanks! Also... what is the best time of year to do anything with it?
