In connection with this discussion it should be borne in mind thatthere are also some trees and shrubs such as the flowering dogwood,Judas tree, and lilac, which are not so much benefited by annualpruning, and which should be pruned only by the most capable ofexperts, There is a group of plants which practically require only the removalof dead wood and superfluous growth. These trees and shrubs are aptto be more or less injured by the operation of pruning. They normallyare comparatively slow growing. They have a tendency to grow in-formally and to maintain the normal shape of the plant as they con-tinue to increase in size. The operation of pruning does not encouragea sufficient new growth and oftentimes so changes the physiological con-dition of the plant that the flowering ability is impaired to a markeddegree during the succeeding one or two years. |
