Crowning of trees: the purpose, types and methods

At first glance it may seem that the trees are notneed special care and even without human intervention are able to grow and please the eye for a long time. However, this is not quite true. A sick or dry tree can become quite dangerous for others, which is why plants need constant monitoring and care. One possible way can be the crowning of trees.

Basic trimming objectives

Croning is the process of shaping the outlines of trees, as well as large shrubs.

This is done with several purposes:

  • ornamental: the main purpose of pruning trees involves giving the crown a certain shape;
  • functional: using this procedure, you can balanceformed imbalance of the crown and the root system of the tree, prepare the plant for winter or revitalize the tree by removing weak, dry and diseased branches.

The main types of tree crowning

To date, there are three main methods of pruning:

  1. Sanitary roofing of trees. Is the removal of dry, damaged branchesand trunks, as well as those that are susceptible to various diseases. This will help significantly improve the tree itself, thereby reducing the risk of rotting tissue. Also, the result of the procedure will be the release of additional power reserves of the plant, which it spent on the vital activity of diseased branches.
  2. Rejuvenating crowning of trees. Assumes the removal of those branches thatcharacterized by a long life. This is in favor of younger and more promising shoots. This will allow the crown of the tree to be cut to provide more light to branches and plants that are in shadow.
  3. Forming the crowning of trees. Depends on the type of green plantation. If pruning of the fruit plant occurs, the skeletal, non-fertile branches, and also the growths that thicken the crown are removed.

In addition, it is possible to distinguish(giving the necessary direction of growth to young branches), thinning (thinning the crown), lowering (performed to protect power lines and balconies) and increasing (to free space under the tree).

Which trees can be trimmed?

In carrying out this procedure, consideration should be given toFeatures of the process for each individual type of tree. For example, such species as elm, poplar and maple are most easily tolerated by pruning. But conifers, oak and birch require special care after this.

In addition, the duration of the healing process depends on the direction of the branch as well as the way the damage is handled.

When is it necessary to conduct the crossover?

Do it best in the early spring. This is due to the fact that it is in this period that you can determine the state of each branch. However, it is still necessary to take into account the species of the tree, as well as the location of its location.

The crowning of poplars and coniferous trees is carried out as they grow. But pruning fruit trees, such as apple, pear, plum and others, is required every year.

Technology of work

The process of crony is always associated with the removalsome amount of wood. As a result, there is a loss of nutrients. To reduce it, you need to carefully plan the process to finish before the kidneys are dissolved on the tree.

After the removal of especially large branches, the wound formed can heal for several years. To speed up this process, you need to follow certain rules:

  1. Cut the branches in such a way thatThe plane of the cut was in full coincidence with the edge of the annular influx. This will achieve a minimum wound surface, and, accordingly, a shorter healing time.
  2. In the case of the removal of particularly large branches, it is necessary to start the burrow at a distance of 20-30 cm from the intended cutoff point. This will prevent wood ruptures.
  3. When working on a tree with a flat or rounded crown, you need to translate the branches to the side branches.
  4. After removing branches, the cut surface is not neededtreat with var, as this can lead to decay. However, if the purpose of trimming was to remove the branches prone to disease, treatment would still be required.

crowning of trees

The process itself, regardless of the type of tree, occurs in several stages:

  • choice of crown shape;
  • a cut of lateral branches (skeleton to touch it is not necessary);
  • thinning of internal processes;
  • removal of trunk;
  • giving the crown of the chosen form.

However, nevertheless, there is some specificity forof each individual breed. For example, poplar popping is a very topical issue, since down can cause allergy attacks and other troubles. This tree grows fast enough, and to prevent the emergence of a large number of flowering products, virtually all branches are pruned.

Trimming of fruit trees, for example, the formation of the pear crown, also includes cleaning the bark and treating it with antiseptic means to protect the plant from diseases and attack parasites.

Types of tree crowns

To ensure that the landscape has a well-groomed and aesthetic appearance, trees and shrubs are given a variety of shapes. Among them:

  • Round: spherical, oval, ovoid;

 types of tree crowns

  • prostrate: the crown of the tree is stretched in a horizontal plane parallel to the surface of the earth;

pear crown formation

  • Sprawling: without clear outlines;
  • the pyramid.

A tree that has been cropped to fit the technology and landscape requirements of the site will be attractive and healthy for a long time.
