You can take steps to set things right again. Bad pruning locks you into a high-maintenance regime. In addition, it degrades the long-term health and beauty of your tree. Aesthetically, pruning cannot accomplish what people think it can. The pruner selectively thins out rubbing branchs to reduce bulk and clutter, and to admit more light and air.
Thinning makes tres less prone tpo damage in windy areas.
Thinning includes removing some of the lowest branches as well, especially those that interfere with pedestrian or car traffic or those touching the house. The sensitive pruner knows not only how to cut, but when to quit. Not all trees take well to thinning. A pine will layer out dramatically, but a cherry tree will sucker readily with even light thinning. Dogwood, magnolias, crab apples, and plums also are quick to sucker.
