The essence of Chimonanthus praecox bonsai lies in pruning, because its branches grow vigorously, especially in the roots and neck, and it is easy to grow lush side branches. Chimonanthus praecox is resistant to pruning and easy to shape. Even if it is not carefully pruned, it can still grow rich branches. Most of the branches that grew in that year can grow buds, especially the shorter branches grow the most flowers.
Usually, after bloom is finished, it can be pruned. It is necessary to remove the branches that are too dense and sick, and cut off the upper parts of the branches of that year, leaving only the base with buds. After the new branches grow leaves, they should be pitted so that the flower branches can grow short and strong, and the whole plant can grow more evenly. Pruning is best to grow in spring and stop in summer. If pruning is carried out in inappropriate seasons, many useless branches will grow, which will disperse the nutrition of flower buds and affect the quality of flowering.
The shape of Chimonanthus praecox after pruning is quite different from that of ground planting and potted plants. Among them, Chimonanthus praecox planted on the ground is very strong. If left to grow naturally, many messy branches will grow, which will not only affect flowering, but also affect the overall shape. Therefore, it is necessary to adopt the method of solitary cultivation, that is, after planting, choose the strongest branch to plant alone, and all other branches are cut off, and it can grow to one to two meters high in less than one year. In the meantime, we will continue to prune and reshape. Once other branches and buds are produced in the roots, we will immediately cut them off, so that in about three or four years, we can grow into a wintersweet tree with a height of four or five meters.
Potted Chimonanthus praecox, after repeated pruning and shaping, can eventually become a landscape pile with strange shape. Before the landscape pile was put into the pot, only the thickest trunk was left, and other branches were cut off from the base, leaving only three upward lateral branches, and the trunk was also truncated so that flower buds could grow on these three branches in the future.
In the future, the flower branches should be shortened in time every year, and other over-dense side branches should be trimmed at the same time, so that the vigorous and ancient image can be gradually presented. At this time, various forms can be created simply through artistic modeling. Pruning should also be carried out when flowering in winter, and all the dry, dead and overgrown branches should be removed, so that wintersweet can bloom more and more beautiful flowers.
Pruning during the vigorous growth period of Chimonanthus praecox should also be done well, and the residual flowers and weak buds left behind should be wiped off. Pruning in this period is very important to the modeling of Chimonanthus praecox bonsai, which is related to the morphological presentation in the late flowering period.
