For bonsai creators, in order to pursue the highest ornamental value and artistic effect, they often do everything possible to make bonsai trees grow better and have more beautiful shapes. Among them, it is more common to thicken the branches of bonsai trees. Obviously, for many bonsai trees, the thicker branches become more ornamental. So, how can bonsai trees become thicker?
Under normal circumstances, the growth rate of bonsai trees is accelerated to shorten the time for the branches of the trees to thicken. The growth process of bonsai trees is actually a process of accumulation of nutrients. Accelerating the growth of bonsai trees is usually achieved by supplementing nutrients and increasing nutrients.
Topping is mainly to remove the growing points on the top of the tree in time. Through topping and topping, not only can the growth height of the trees be controlled and the purpose of dwarfing can be achieved, but also the path of nutrient transmission can be changed so that a large number of nutrients will accumulate at the bottom of the top branches, so as to achieve the purpose of thickening the branches of the trees.
In addition to increasing nutrients to thicken the branches of bonsai trees, we can also stimulate plant growth by applying plant growth hormones. Commonly used plant hormones include chlormequat, paclobutrazol, trunk thickening liquid, etc. After reasonable application, it can not only inhibit the growth of trees but also achieve the purpose of thickening branches.
Local trauma to the tree is an important means to promote the thickening of bonsai trees, mainly through artificial trauma to promote the differentiation of the cambium of the tree and then make the branches thicker. After the tree is injured, the cambium will accelerate the differentiation to allow the wound to heal quickly. The process of thickening branches is actually the process of differentiation of the cambium to form phloem and lignification. Therefore, we often see that after a tree is injured, a relatively large tree tumour will form on the wound site for a long time, which is similar to the scar formed after a human body injury.
Multiple strains of binding
Sometimes, we plant multiple trees in a flowerpot, and in order to achieve the effect of thickening, we can tightly tie multiple trees together and let them grow close to each other. After a period of time, we peeled off the bark of the parts of the trees that were close to each other and then continued to tie them together. Over time, multiple trees will grow tightly together, like a thicker tree. The principle of thickening trees is similar to grafting.
