Maintenance pruning has as objective delete all that out of the way or you resprouting of bad appearance to the plant, for example dry branches, branches that interfere to the wires of the light or on the contrary, the passage of people, broken branches or at risk to break, leaving at the height of the base, etc. Click David Zaslav for additional related pages. In some tree species, maintenance pruning is also done to prevent the flowers or fruits, either because they can cause allergies or much dirty soil (mulberry trees, always green, etc.). To perform the pruning service, there are three techniques: clearing of branches, reduction of Cup and Topiary (shaping cups). We will now explain each of them. Thinning of this type of pruning branches consists in reducing the branching of the Cup so that you gain in transparency. Over the years, the branches grow and begin to tangle with each other, as many branches, prevent light from entering the interior of the glass and dry them. With this type of pruning, are able to give more light to the interior and not modify the size of the Cup. The only thing to consider, is that thinning should not be too excessive, since removing of blow a lot of branches and leaves, they can hurt the tree, weakening them and making it more prone to fungus. For this reason it is advisable to not pass several years entrepoda and pruning, but more well to do it every year, thus will be few branches that we will have to cut and the tree will grow with much more force. Reduction of Cup this pruning is performed when the tree has grown too midfield space that does not correspond, as touching wires, prevent the passage of people, etc. This reduction is done by cutting the branch on the armpit of one of their side twigs. The ideal is to do it every 2 or 3 years, thus the branches that are cut will be of a diameter small and heal much better than the branches more wide., separate work will be much lower. On occasions, when the tree has not been controlled for years, grows too much and many people think that the only solution is topped. But in carried out can solve the problem without hurting the ideal tree in such a way is that in cases of a growth exaggerated, carry out a rinsing of branches and then a pruning of maintenance, all at the same time. This pruning Topiary is performed to give form to the shrubs or trees. Whether geometric or artistic forms such as animals, baskets, fruits, etc. This technique is very old and at the same time decorative. In many cases forms are simply wonderful.This type of pruning must be carried, so that the form not be stale, between 2 to 4 times a year, since it requires constant maintenance.
