Prune your rose bush in early spring, never in the fall and never in the winter. Check your rose bush from time to time as spring moves along and when you start to see new shoots growing from the canes on your rose bush, that’s a good sign that it is time to prune.
You will need a few basic tools when the time comes to prune your roses: gloves, because of the thorns on your rose bush. Lopping shears, for some of the heavier canes that are going to be difficult to cut with some of the smaller shears. Small hand shears, for some of the finer work, and a pair of hedge trimmers to get the job done quickly.
Determining how high you want to prune depends on how high you want your rose bush to finish. Your rose bush will usually triple in size after pruning so cutting it back to about a foot will leave it at 3 feet when it finished growing.
