First: clean

Because it has been destroyed by nature, many germs will be attached, and some will be eroded by germs, so it must be cleaned when used. For the purpose of sterilization, it is necessary to add an appropriate amount of insecticide when cleaning, but the concentration should not be too high, otherwise it will affect the color of the dried relic, thus affecting the appreciation value of the bonsai.

Second: drying

After cleaning, it should be dried in the sun, but it should not be exposed to the sun for a long time, otherwise it will burn the branches and affect the color of the dried relic. The purpose of drying is to evaporate all the water in the branches. If the branches are wet, it will breed or attract all kinds of germs, slowly corrode the branches and even affect the growth of other plants. Therefore, it is necessary to dry it often, especially in the south. Due to the humid climate in the south, long-term humidity of branches is easy to breed germs.

Third: management

Dead branches will rot slowly because they have no vitality, so it is necessary to coat or spray relevant preservatives in the daily management process. In addition, in order to avoid the infiltration of water, you can paint some special oil on the branches, water the bonsai and expose it to the sun.
