Keys to Good Pruning

For most deciduous (broad) trees, please do not cut out from 1/3 of the total height of the tree under the tree.

If possible, ensure that the lateral branches form a vertical angle and form an angle of "10 o'clock" or "2 o'clock" for the trunk.

For most species, trees should have trunks. Before cropping the form, decide on the best leader and the later branch before trimming and deleting the problem part.

Do not worry about protecting the trim cut. For aesthetics, you may find it better to draw big scratches, but it does not prevent or reduce corruption

Please use rod trimmers for tall branches. The main work of big trees should be done by professional Arboreist.

In the case of large branches, cut out the bark and the outside (swollen part) of the backbone. Please do not leave outstanding stubs. When limbs are too small to be able to form a tight collar

If you shorten a small branch simply, it will be cut at the side bud or the opposite branch. Like a sprout, make a branch that grows in the desired direction (normally outside). The incision should be made clearly clean, at a slight angle of over 1/4 inch above the sprout.

Trimming: The trimming itself is the theme. Of course, you learn fundamentals, remove intersecting branches, suckers and stems, open old plant and activate it, select your fruit trees and shrubs annually to allow good air circulation to prevent disease You would want to prepare. Control of insects and diseases: If you choose a disease-free tree and shrub according to good cultural practices, you should be able to control the most common orchard pests and diseases without using chemicals . However, in order to organically cultivate fruits, it is necessary to withstand the damage of some degree of pests and diseases. If you want to prevent the damage of all insects and diseases, you need a toxic spray library - everyone does not want to use around the family landscape

Pruning removes dead limbs from living skeletons of potential high-value crop trees. A tree properly arranged by cutting a branch flush with the stem creates a knotless tree when the wound heals. Pruning also provides some people with visually more enjoyable forests and improved safety and access. Pruning is a good investment if a knotless log brings high price such as white pine, red oak, black cherry, black walnut etc. Prescribed fire is a convenient afforestation tool that simulates natural ecological processes. Using fire as a breeding ground for pre-built middle-aged or mature forests reduces fuel accumulation, reduces the possibility of destructive forest fires, improves wildlife habitat, eliminates unwanted shrubs and tree species You can prevent. Promotion of biodiversity of plants and animals, reduction of certain insects and diseases, and beneficial tree regeneration

Trimming can start with root or leaf. The simplest pruning method starts with leaves and removes each node of the most popular class in the leaves. If accuracy does not degrade, keep this change. It is also known to reduce false pruning. A more sophisticated pruning method can be used, such as pruning cost complexity, using learning parameters (α) to weight whether nodes can be deleted based on the size of the subtree. This is also known as the weakest link pruning. This is the most basic way and can be compared with learning decision trees. Learning of decision trees was improved using enhanced technology. A common library for implementing these algorithms is Scikit-Learn. It has a nice API that allows your model to execute a few lines of code in python
