New growth and emerging flowers are the delicate parts of each plant that provide both natural beauty and contrast to the mature foliage. As hedges and trees are groomed and pruned, one should take care not to remove these delicate parts of the plant with each service and the plants beauty will be maximized. With time however, hedges, shrubs and small trees can become larger than the designer intended and need a heavy pruning once a year (usually in the summer).
