E...I am not an expert yet on blueberries...even though I grow 3 varieties and have studied them for a few months. Usually, you can cut apart cane type plants and divide easily. Also, consider at least one more variety for enhanced fruit production. There are several bb experts here that will pipe up.

Hello eight_pieces,
If it was me,I'd keep the shrub intact and buy some more.Blueberries do better with different varieties.
I do grow Blueberries from cuttings and my success rate is fifty percent at best and that is with a misting box,as the leaves need an almost constant film of water on them until roots form. Brady
