Rejuvenating cuts. Plant rejuvenation (usually shrubs) consists in cutting the older branches in the lower or ground part in order to stimulate the plant to produce young and usually numerous shoots. Rejuvenation cuts are applied to these shrubs, whose old branches are of low vitality, cause undesirable compaction, wrong habit, too large bush sizes, etc..
The rejuvenation treatment can only be carried out on shrubs growing under normal lighting conditions. A common mistake of trying to rejuvenate shrubs distorted by a lack of light, growing e.g.. under the treetops. As a result, several weak shoots excessively elongated and bent to the light are obtained. In such cases, it is most advisable to remove the bushes, the, which may also be reasonable, removal of the shading tree. Should be added, that the removal of old thick branches leads to the formation of large wounds and rapid decomposition of the root of the bush, and may even lead to its dieback. The result of rejuvenation depends not only on this, whether the bush has enough light for a given species, but also from proper fertilization and watering.
Cuts to reduce the size of the plant. This type of pruning is used when a tree or shrub exceeds the acceptable dimensions and e.g.. unwanted obstruction of the view, contact with power or telecommunications cables, window covering, etc.. Limiting the size of plants may result from the adopted arrangements or compositional assumptions. The cuts made for this purpose usually cause a lot of trouble to the employees obliged to carry them out due to technical difficulties and high labor intensity.. The quality of such cuts is usually bad and endangers trees. Sometimes it is possible to avoid cuts by appropriate reconciliation of various elements of the environment with the existing woody plants or by their proper selection in specific conditions..
