Four seasons cinnamon pruning method;

1. Pruning method.

In order to restore the tree potential and promote the growth of the root system, only the large seedlings with larger seedlings and more branches and leaves are moderately shortened to facilitate the recovery of vitality. The other seedlings can be left to grow naturally, so that the desired effect can be achieved.

2. Prune in the second year.

During the germination period of the second year, we should pay attention to controlling the height of the plant, using the techniques of suppressing the strong and helping the weak, pressing up and down, and controlling the front and promoting the back, etc., to ensure that the upper part of the hedge as a whole is not strong, the lower part is not weak, the height is consistent, the hedge base is not empty, and the top of the hedge and both sides are relatively straight, so it can be basically finalized. Then, based on the height of most seedlings, the main tips are cut off by 1 3. Then take this as a standard, set the pile position line at both ends of the hedge, so that the height of the whole hedge is consistent.

When cutting off the main stem (central branch), the cut should be placed on the first branch below the specified height, which can not only avoid the exposure of the wound of the main stem, but also promote healing and allow the normal growth of the leading branch.

3. Annual pruning.

As the new shoots sprout and grow, keep the local branches short and do not keep them away from the hedge. At the same time, it is also necessary to ensure the strength of the base and strictly prevent the decline from drying up. Therefore.

For the pruning of hedges, it is necessary to have an overview of the overall situation, taking into account the growth and appearance of the upper and lower left and right. For the possible basal baldness and premature aging, it is especially necessary to check it diligently, and update it before it is pre-aging. In terms of pruning methods, it is necessary to pay attention to both winter and summer, combine light and heavy, and focus on pruning during the growth period and moderate heavy pruning.
