Root pruning is the reduction of the root system that occurs during the periodic repotting of a bonsai. Pruning coarse roots helps the root system renew itself and become more dense. Fine roots are generally more efficient at absorbing water and nutrients than coarse roots, which primarily exist to anchor the plant and store energy in the form of starch. These are two functions that are not particularly important in bonsai culture.
