Single-stem method is to cut off the lateral branches from the seedlings, leaving only one main branch in the future. Usually used in dahlia, single chrysanthemum, peony and other flowers with large flowers.
Many stems begin to pick their hearts at seedling stage, which promotes them to form more lateral branches and bloom more flowers. For example, pomegranate can leave 3 ~ 5 lateral branches, and chrysanthemum can leave 5 ~ 7 lateral branches.
Clustered shrubs or bamboos, such as a bunch of red bamboos, Buddha's belly bamboos, Guanyin bamboos, nandina bamboos and canna, are often reshaped. And the density should be commensurate and the height should be appropriate.
Hanging branch type is also called climbing type, which is mostly used for trailing flowers. Erect supports for flowers to climb and grow, such as morning glory, golden lotus, grass radish and so on. , convenient for vertical greening arrangement.
When remodeling flowers and trees, on the one hand, we should conform to the natural growth trend of flowers and trees, and at the same time, we should give full play to their respective characteristics, and carry out artistic processing through modelling technique, so as to combine natural beauty with artificial beauty, thus improving their ornamental value.
Generally speaking, flower modeling can be divided into two categories: natural and plastic. The purpose of natural modeling is to make the branch layout more reasonable and beautiful by pruning and thinning on the basis of maintaining the original plant shape; The modeling method is to make flowers and trees into trees according to people's different hobbies, forcing them to change the natural growth trend and create various plant shapes that people imagine, so even if the branches are distorted, they will not hesitate. For example, stump bonsai often forces the trunk to hang horizontally or downward; For shrubs with thin branches, they can be raised and bent; Climb vines and flowers, set up various forms of scaffolding for artificial induction or weaving beat for traction; For flowers and trees with arched lateral branches, a bare trunk should be artificially cultivated, and then the lateral branches on it should droop; For flowers and trees with weak branching ability, more lateral branches and layers should be promoted by re-cutting.
Before shaping flowers and trees, the plant type should be designed in advance, because a woody potted flower with perfect plant type can't achieve the ideal effect once or twice after growing for many years, and sometimes it takes years or even years of careful cultivation. Therefore, when carrying out plastic pruning every year, we should pay attention to the length of branches and the thinning parts of branches, and don't prune them rashly, otherwise a pruning mistake will cause irreparable losses.
