Pruning landscape roses is very simple. Like other roses, they should be cut back before winter to around 30 inches high to reduce their loosening from the ground by winter winds.
Then cut them back a little more in the spring. Start by first removing all broken or dead canes. To maintain size, cut them to about 20 inches. Soon afterwards they will sprout vigorous new canes that will produce many blossoms. Periodic light trimming of the canes may be needed to keep them within bounds throughout the summer.

About the only time not to prune is late summer and early fall, as this might encourage late growth that wouldn't harden off in time for winter. In the North, winter is not a good time to prune, but winter is just fine in the South. So periodic pruning is necessary to keep it manageable. Trimming these off brings it back into bloom.
First, put on some heavy leather gloves. Now that you have gloves on, let's proceed. Use a good pair of hand pruners to shorten small branches a half-inch thick or less and loppers for thicker ones. Cut back to a leaf or an outward-facing bud. They make clean cuts and minimize damage to the stems. Wear a sturdy pair of leather gloves and long sleeves because no matter how careful you are, thorny roses can painfully puncture or scratch your hands and arms.
Should you need to cut canes larger than one-half inch in diameter, you should use loppers. The first pruning is done anytime from late January to mid-February. Pruning any later will delay the outstanding spring and summer flowering. There is no set way to prune a Knock Out rose or other landscape roses.
It depends entirely on the desires of the gardener and the situation. If you want your roses to grow large to form a screen, you would do only light pruning and cut out any dead wood. In a situation where the bushes have grown too large, decide what size they need to be for the location. Cut the bushes back about 1 foot shorter than you want them to be within reason, you should never cut them back shorter than 2 feet tall. A general recommendation for the late-winter or early spring pruning is to reduce the height of the bushes by about one-half to one-third.
You may do this even if the shrubs are sending out new growth. If the winter is really mild, they may even be producing some flowers, but you still need to prune.

If you leave them, they'll form rose hips with seeds inside and flowering will slow to a crawl. Unless it dies, it will get bigger and bigger every year.
