Cedar adopts the modeling method of central leadership and low branches. For the seedlings with weak head bending, the twigs should be tied up with thin bamboo poles to make the trunk straight, and at the same time, the growth advantage of the top should be used to make it grow taller. Binding once a year. If there are competing branches on the trunk of cedar, choose one as the central trunk, shorten the other, and sparse that branch the next year.

Selection and retention of large lateral branches of cedar

Because of the irregular rotation of cedar lateral branches, too many and too little spacing, the crown is lush and closed, resulting in uneven distribution of nutrients and uneven growth of each lateral branch. Therefore, when pruning, it is required to arrange each side branch in layers on the trunk. Each layer should have 4-6 left and right lateral branches, and the distance between layers is about 30-50cm. Pay attention to protect new shoots and remove too dense branches at the same time. For thicker branches that are not used as side branches, they should be cut short first and then cultivated for a period of time.

Need to balance the potential of snow pine trees

In order to form a beautiful cedar crown, the lower branches are required to be long and the upper branches are shortened in turn. In addition, the growth of lateral 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 that grow too fast, appropriate retraction pruning can be carried out, and parallel branches or drooping branches with weak growth can be selected for replacement to balance the tree potential.

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

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

Pruning of Cedar skeleton tree

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