<human>:  What is the best way to prune a rose bush?
<bot>: The best way to prune a rose bush is to wait until after the last frost of the season, then prune down the bush to a desired height. Remove dead and dying stems, crossing branches, and any weak or diseased wood. Make sure to make cuts just above outward-facing buds. Doing so will open up the center of the bush for better air flow, and promote more branching, resulting in more blooms.
