Cutting trees and shrubs can be performed at any time of the year. However, with regard to specific species or groups of plants, there are the most advantageous cutting times from the point of view of their influence on the course of physiological processes, and especially the intensity of growth and flowering. The most suitable pruning season for most woody plants is the dormant period.
Pruning of young shoots of trees and shrubs can be carried out during the growing season, when these shoots are not yet lignified. Cutting at this stage is performed on hedge plants. The advantage of cutting in such a period is the ease of cutting soft shoots and the possibility of spreading plants during the same growing season.. Often, however, new shoots regrowth do not lignified sufficiently before winter and then dry out. In some species of trees and shrubs, sap drains after branches are cut (clones, chestnut trees, elms, vines and others), which is a harmful phenomenon for these plants. It then occurs, when cutting is made at the end of the dormant period, when, as a result of the trunk heating, the juices were stimulated and circulated. Therefore, pruning in species with such a reaction should be carried out at the earliest, so no later than mid-February. If the cut could not be made within this period, then they can be performed in these species after a clear or full vegetation has started. During the growing season, there is no leakage of juice in the places of cuts.
