Things You'll Need
Miniature roses make a dainty and surprisingly vigorous addition to any indoor or outdoor garden. When caring for the basic needs of the miniature rose, pruning is often neglected, since many owners consider this a disposable plant. In order to maximize your blooms and create a thriving, hardy little rose, pruning is essential to its care.
Prune after blooms begin to fade. During the growing season, a miniature rose will bloom several times. As each bloom fade, prune that cane back to an area where leaves are growing. It is your discretion how far back to prune, however an overall rounded shape is desirable in roses. Typically this can be done with scissors, but use pruning shears if necessary.

Prune when growth becomes unruly. During the growing season, your miniature rose will grow abundantly. This can lead to your rose looking tall and leggy, and not full enough. If you notice this happening, prune back the new growth to where it meets the original cane. Take your time and prune back one branch at a time, stepping back to look at the overall shape of your rose. Don't worry if you are too aggressive and the plant looks skimpy, it will grow back just fine.
Prune in the spring. Just as growing season begins, take a close look at your miniature rose. Find 5 or 6 of the healthiest canes of the plant. Cut back any new canes that are growing to make the rose focus on growing on these canes. The more growing focused on the stronger canes, the stronger your plant will be.
Prune any dead or damaged leaves and branches. Whether during the winter or the growing season, damaged or injured branches and leaves should be removed. Make sure to discard these pieces away from the plant to avoid the introduction of disease or insects who may be attracted to the decaying pieces.
Do not prune in the fall, except to remove dead blooms. The plant will respond by trying to start new growth, which will be damaged in the first frost. This could introduce disease and greatly weaken the miniature rose.
