Answer: Knock Out roses require less maintenance than your hybrid teas. You can prune to remove the spent flowers but generally the plants are left alone until late winter or early spring and then pruned back by about a third to a half. If you don't like seeing the spent blossoms you can prune them off but it isn't necessary to prune back to a 5-leaflet leaf as you would on other roses.
Enjoy your new roses!
