The branches of the bonsai bonsai will inevitably be damaged, and even affect the shape of the pruning. Effective measures can be taken to restore the wounded branches or restore the original state. As long as the branches are not completely broken, even if only about half of the branches of the bark are connected, it may be saved. The specific method of recovery is to first carefully align the fractured strands of the broken strands, and then take a relatively straight, medium-sized fine iron wire that exceeds the length of the fracture, bind one end of the wire to the broken end that is connected to the mother, and bind the other end. In the well-arranged branches (if the broken branches are curved branches, the wire should be bent to adapt to the extent of the fault). After the ligating and positioning, according to the proportion of moss 3 points, 7 points of the mud with a diluted solution of vitamin b12 mix and apply in the anastomosis. Always apply water to maintain humidity and place it in a cool, ventilated place. If the damaged branch is a minor injury, which does not interfere with the growth of this branch and does not affect the overall shaper, it can be allowed to heal naturally. It can also be directly wrapped with hemp rope. Different tree species, different degrees of damage, the healing period is also different. After 1 to 3 months of maintenance, after the wounds of the broken branch are basically healed, the bonsai of the tree stump can be moved to the original place. After normal cultivation, it can be removed and coated after half a year.
