As the saying goes, flowers and trees are divided into seven parts and three parts, which is an important flower cultivation experience. By cutting off unnecessary acrobatics, pests and diseases, or properly treating branches, it can save nutrients, reduce consumption, ensure the centralized supply of needed branches and leaves, or promote flowering, so as to achieve the goal of more flowers and more fruits. But also can adjust the tree potential, make the branches of flowers and trees evenly distributed, control excessive growth, and ensure the neat and beautiful shape of flowers and trees. In addition, pruning can also make flowers and trees reach the ideal height and thickness, reduce the occurrence of pests and diseases, and help improve the survival rate of flowers and trees. There are many ways to trim. The following are some commonly used pruning methods: (l) Short cutting: that is, cutting off a part of branches, generally cutting off 1/3-3/4 at the front of branches, in order to prevent the branches from elongation, and at the same time promote the sprouting of the cut axillary buds, ensure the growth of more lateral branches, expand the periphery of the crown, increase the flowering parts, make the crown evenly distributed, and make the plants deformed and plump. It is also beneficial to increase the number of flowering points and ensure that plants bloom and bear more fruits. (2) Thinning: When plants are flourishing, cut off overlapping branches, inward branches, pests and diseases branches, overgrown branches and aging branches, and cut off leaves damaged by pests and diseases or leaves that are too dense. The purpose is to improve the ventilation and light transmission conditions of plants, reduce the occurrence of pests and diseases, be conducive to the healthy and robust growth of plants, and adjust the tree shape to make it clear, tidy and beautiful. Thinning won't leave a stump like cutting corners. Thinning is trimmed by the base, leaving no residual piles. For foliage flowers with markings and mosaic, if the green branches grow stronger than those with markings and mosaic, the green branches should be pruned in time to prevent the green branches and leaves from covering the branches with markings and mosaic, and keep the characteristics of the original varieties: pay attention to conifers not to defoliate. (3) Picking the heart: also known as removing the tip and topping, picking the terminal bud of the tender shoot directly with your fingers, breaking its top advantage and promoting the germination of its lower axillary bud, so as to achieve the purpose of inhibiting the overgrowth of branches, promoting the multi-branch of plants, forming multi-flowered heads and beautiful plant shapes. Such as four-season begonia, a bunch of red flowers, lotus flowers, Bali Snow, Murraya Murraya, Admiralty and so on. , all need to be plucked. (4) Bud wiping: the axillary buds and twigs of the flowers are erased to save nutrients and ensure sufficient supply of main nutrients. (5) Leaf removal: To make flowers more beautiful, yellow leaves, residual leaves, diseased leaves and leaves covering flowers and fruits are removed. (6) thinning flowers and covering fruits. Therefore, too dense flowers and fruits should be thinned, because the flowers left behind may not always bear fruit, so the flowers left behind should be 2-3 times the expected number of fruits, and then the excess young fruits should be thinned after the fruits are set. Potted flowers, such as camellia, tend to form too many buds. In order to make them look better, they can be thinned appropriately. Dewatering buds should be carried out as soon as possible to avoid excessive consumption of nutrients by redundant buds. Generally, we should do it when we can distinguish flower buds from leaf buds. Break off the extra buds and leave 1-2 flowers on each twig. Potted flowers ready to harvest seeds in water should be picked off in time after opening to avoid consuming nutrients. (7) Hairdressing: large flowers such as rubber tree, Liriodendron chinense, and king's generation of pink leaves are too tall to be cultivated indoors and need to be shaved.
