The severe pruning and topping cuts involve large (and therefore the main branches) and drastic removal of the summit. This kind of intervention is bad because with it you go off suddenly, most of the leaves through which the plant feeds (it in fact, unlike what is commonly thought, do not feed through the roots) and is induced the tree to produce new and quickly, giving background to the reserves accumulated in previous years and suffering, ultimately, a nutritional stress . Add to this stress by irradiation of the trunk of the plant until then protected by his own hair, by bombardment of ultraviolet rays. The production of numerous branches next to a severe pruning should not mislead: they are not a sign of vigor, but the energy expenditure of reserves that the plant is forced to put in place to try and run for cover for its nutritional deficiencies and sunscreen, and to rebalance the crown underground: the roots. Moreover, large cuts are not easy to heal and pathogens that cause wood rot, arriving before the tree can stop them with their chemical barriers: the rot and then also reaches even the larger branches or even the trunk, making the entire structure unstable and dangerous. Finally, a tree pruned dramatically loses value and is aesthetically ugly. E 'must surely intervene if the tree has been damaged, such as lightning. But it is for the young plants to give them a proper shape and a strong structure, always running very small cuts and using the material already present on the plant, without inducing the production of new branches are not predictable. Pruning is important because it affects the whole life of the plant, its size to fit your requirements and the type of pruning to be charged in the future. In addition, the pruning should be performed periodically on adult plants to clean up the dead branches or those attacked by pathogens due to rot. Finally, prune when the plant is not for you but for our needs, let's do it before the tree is over dimensioned, since it has reached a size acceptable to us on, we will always hold it with light cuts and thin out the foliage eliminating the weaker branches. Pruning should be performed preferably in winter, even though every season is good, to avoid are essentially spring to bud and formation of new branches and autumn, during the loss of leaves.
