The hibiscus's pruning should be carried out after flowering. The trees can be trimmed into arbors or pruned into bushes. However, regardless of the type of tree, the dead branches, weak branches and inner lychees must be trimmed to ensure that there is a crown inside. Good ventilation and light transmission. The large wounds caused by pruning should be closed in time with the “wound-proof and anti-corrosion film†to prevent dry cracking, pests and diseases, and to protect the rapid growth of callus. Every winter in the winter, planting some ripe organic fertilizer around the plants, timely watering and soil sealing after fertilizing, strong tree vigor and enhanced resistance. The insulation and antifreeze work must be carried out: the tree trunks and branches of the hibiscus being sprayed with the protective agent “General Tree Guard†should be insulated to quickly form a protective film, and the film-forming substance protects the twigs of Hibiscus syriacus from wintering to avoid freezing injury; , To prevent the reproduction and infection of pathogens, kill overwinter eggs of insects such as aphids, red spiders, and shield bugs. Through insulation, antifreeze and sterilization, it provides a good environment for the safe wintering of Hibiscus syriacus.
