Pruning technique of sweet-scented osmanthus bonsai

Pruning is very important to improve the ornamental value of potted sweet-scented osmanthus. Pruning, especially heavy pruning measures combined with comprehensive management of water and fertilizer, plays a good role in regulating and promoting the growth of aged potted sweet-scented osmanthus. It can coordinate the contradiction between potted plant height and greenhouse height, and properly solve the problem of overwintering management of northern potted sweet-scented osmanthus.

The following is to provide you with pruning methods. In terms of modeling, pruning and climbing are all to change the bending form of branches and occupy the space position, so as to achieve the purpose of tree modeling. In terms of maintenance and management, pruning is to maintain and maintain the formed tree landscape. According to the modeling order, it can be divided into positioning cutting, shrinking cutting, thinning cutting and so on.

Pruning time: grafted sweet-scented osmanthus should be pruned in dormant season. There are many Rain Water in the plum rain season, the air humidity is high, and the trees grow vigorously, so they should be cut less or not re-pruned. A large number of branches and leaves will be cut off will affect the normal growth and lead to death in serious cases. In addition, close to the end of autumn can not be re-cut, after strong cutting, new buds sprout one after another, cold snap will freeze to death buds. The best time for heavy cutting and strong cutting is that the trees are dormant from January to February.

Generally speaking, trees with strong and exuberant growth can be cut more, while those with thin growth can be cut less. From the needs of tree modeling, it is usually necessary to cut off cluttered cross branches, overlapping branches, parallel branches, whorled branches, opposite branches, thin branches, sick branches and so on. If the nutrients of the branches are concentrated, they can grow strong.

Pruning method:

The end face of the cutting mouth should try its best to avoid the tangency between the big face and the branch at an angle of 45 degrees, and the leaf buds remain on the upper side of the oblique mouth. In the growing period, can be posted near the leaf bud pruning, conducive to wound healing. In the non-growing period, it can be pruned at the upper end of the leaf bud.

Positioning scissors: refers to the first pruning of sweet-scented osmanthus shape, making sure to retain the branches in different positions and cut off the excess branches. After the tree stumps dug in the mountains survive, they sprout a lot of branches, so they must cut off most of the branches and retain the backbone branches needed for modeling, which is called positioning shears.

After positioning cutting, the number and position of branches and the distance between branches were determined, which directly affected the morphological beauty of sweet-scented osmanthus bonsai. Therefore, before pruning, it is necessary to seriously conceive and consider the form of the tree shape. The so-called "intention is to write first". At the same time, you must be "confident" before you can cut it. Because the choice of branches depends on the establishment of the form of tree scenery. The retained branches should grow sturdily, coordinate the thickness of the top and bottom, avoid parallelism, symmetry and overlap as far as possible, be dense and dense, spread around the trunk, and have momentum.

Pruning: it is not only a pruning method for shortening branches, but also an important measure for tree modeling and tree landscape maintenance. In terms of modeling, the trees are dwarfed by shearing, the branches are plump, the thickness is variable from top to bottom, and the bending changes, so the modeling should pay attention to three points:

The proportion of the thickness transition between the pruned trunk and the upper branch of ① is suitable.

When ② shrinks, keep the direction and angle of the bud eyes in order to adjust the space position of the new branches.

③ pruning nodes should be short and avoid long, the first branch is longer than the second branch, and the second branch is longer than the third branch. In terms of maintaining the tree landscape, for most of the sweet-scented osmanthus bonsai, the overgrown branches extracted during the growing season need to be shrunk to maintain beauty.

Sweet-scented osmanthus bonsai mainly rely on picking buds and hearts to control super-long branches and maintain their original appearance. The dormant period can be shrunk, but the growing period should not be shrunk. Strong cutting is carried out during the dormant period to remove all kinds of taboo branches.

The pruning of sweet-scented osmanthus bonsai depends on the tree, and the large frame is set according to the posture of the tree, and the other tillers, overdense branches, overgrown branches, cross branches and diseased branches are removed to make it ventilated and transparent. For those who are strong in tree strength and weak in tree strength, the upper branch can be cut short by 1 × 3 to make the whole tree strong, and at the same time, the wound can be protected by applying healing and anticorrosive film at the pruning mouth.
