After fertilization, frozen woody medicinal plants are generally weak, and the roots of frostbite's tree body are poor in water absorption and fertilizer absorption. Therefore, after rooting, woody medicinal herbs should be topdressed and fertilized. Attention should be paid to light application, thin application, and multiple application. Promote thick new shoots, help restore the tree vigor, fertilization with nitrogen, phosphorus, potassium-based fertilizer. It is advisable to use foliar spray fertilizers after the occurrence of new shoots. Pest-freezing is likely to cause damage and defoliation of branches, resulting in bare branches. In the future, more serious pests and diseases, such as resinous diseases and sun cracking diseases, will easily occur. Therefore, it is necessary to promptly prevent diseases and treat diseases after freezing. The prevention and treatment of diseases can use Bordeaux mixture, carbendazim and other agents, and can control insect pests such as dichlorvos and trichlorfon.

Pruning frozen leaves is a kind of self-protection measures for the resistance of woody medicinal trees to resist freezing damage. Through defoliation, the abnormal loss of water can be reduced, and the trees can be prevented from dying due to excessive water loss. Post-frozen defoliation will delay germination, so be sure to cut off dead branches and diseased shoots as soon as possible after the buds have emerged and can distinguish between dead and dead shoots. Keep as much as possible the remaining branches and remaining leaves. It is also difficult to distinguish between live and dead shoots. Can be divided into trims. The amount of pruning should be light, the cut should be smooth, and large cuts should be disinfected with 75% alcohol or 0.1% potassium permanganate and wrapped with a thin film.
