You won't hear me talk about ornamental plants much. I put my energy into things I can eat. But there are places near the house where edibles won't do well, so something pretty is better than nothing.
If you don't prune shrubs and bushes near the house, eventually you can't see out the window or get near the structure for maintenance. But to keep the form of the plant while controlling its height and spread requires pruning out full branches, not just cutting back the tops of existing growth.
