Cedar is shaped by low branches and central leadership. For seedlings with bent heads and weak heads, the tender tips should be tied tightly with thin bamboo poles to make the trunk straight, and at the same time, the growth advantage of the top should be used to promote them to grow taller. Wear a tie once a year. If there are competing branches on the trunk of cedar, choose one of them as the central leader, shorten the other branch, and then thinning the shortened branches in the second year.

Selection and retention of large lateral branches of cedar

Because of the irregular rotation of the lateral branches of cedar, the number is too large and the spacing is too small, and the crown is lush and closed, which leads to uneven distribution of nutrients and uneven growth of each lateral branch. Therefore, when pruning, it is required to arrange each lateral branch in layers on the trunk, and each layer should keep about 4-6 lateral branches, and the distance between layers is about 30-50 cm, and pay attention to protecting new shoots and removing over-dense branches, over-thin branches and pests and diseases. For thicker branches that are not used as side branches, they should be cut short first and supported for a period of time before treatment.

Need to balance the potential of snow pine trees

In order to form a beautiful cedar crown, the lower lateral branches are required to be long, and the upper branches are shortened in turn. In addition, the growth of inner branches in the same layer needs to be relatively balanced. Therefore, attention should be paid to the relative balance of the growth of each side branch when pruning. For branches with strong growth, appropriate retraction pruning can be carried out, and parallel branches or drooping branches with weak growth can be selected to replace them, thus balancing the growth of trees.

Adjust the "lower strong and upper weak" snow pine tree

Retract and trim strong branches, overlapping branches, parallel branches, etc. Spraying proper amount of growth hormone on the lower part and the upper part of the plant can promote the growth of branches.

Pruning of Cedar skeleton tree

For skewed trees, branches can be introduced to fill the gaps, and larger branches nearby can be pulled by ropes or iron wires to fill the gaps; Or take the grafting method, and graft strong and full buds on plants with large gaps and no branches by abdominal grafting to promote the germination of new branches.
