I grow Tropicana in a large pot and it is impossible to get it out to divide. Since you can leave yours in the ground year round you may prefer to do that. They would be a lot easier to dig and divide.
For me it is too late to try to save it. It is dead and I still can't get it out of the pot. Something to work on in the fall I guess. It is easier for me to just go out and buy a new start, which I did for another pot.
