<human>:  How do I prune a rose bush?
<bot>: The best way to prune a rose bush is to begin by removing any dead or diseased wood and cutting back any shoots that are larger than two feet in length. Make a clean cut at a 45-degree angle, just above an outward-facing bud. Prune the stems in a way that encourages an even shape and removes at least one-third of the stems. Once finished, apply a layer of mulch or compost around the base to help keep weeds away and conserve moisture.
