I was given a single blueberry plant several years ago but I understand that several plants are needed to achieve pollination. Is it possible I could split this root-ball up to produce the several necessary plants? It seems to be a late summer variety. Since I don't know what variety it is I don't know how I would buy more of them.

Splitting the plant won't help, you must have a different variety. Knowing what genus you have would be helpful. Where are you and at what elevation?
