Bolbitis heudelotii cutting.

Hi, i just recieved two Bolbitis heudelotii plants one seems to be having 4 large leaves with 1-1.5 inch length rhizome. Another one has 9-10 medium leaves with 3-4 inch length Rhizome. I am thinking about cutting 4inch rhizome to 1 inch each with some leaves in them, is that a good idea or should I split 4 inch into just two? Thanks is advance.
