The beauty of banyan tree bonsai lies in the roots, stems, branches and leaves. If the shape of the stems and branches is very complete, but the roots appear thin and weak, the roots are defective, the number of roots is small, the roots are offset, and the roots are uneven. , It will affect the overall appearance. At this time, the root method can be used to make up for it to make the roots more perfect.
Filling the roots can be done by inverted cutting, preferably during the rainy season. Choose the place to fill the roots and use a sharp grafting knife along the cortex of the trunk to gradually deepen into the xylem. Cut a cut about 2 cm in length to form a tongue-like shape with a smooth cut surface. Cut the roots of the banyan tree. The color and thickness of the roots should meet the requirements of replenishment. The cut length should be appropriate, about 1520 cm or longer. The root end is cut into a wedge shape, the size and length of the wedge surface are equivalent to that of the tongue-shaped cut surface, and then connected. The joint should be aligned with the cambium to be dried on at least one side, and then tightly tied with a 1 cm wide plastic strip to wrap the joint. The other end of the root can be directly buried in the pot soil for compaction, and water is poured once. Pay attention to watering, keep the soil moist, and it will be alive soon.
Do not fertilize within 1 month after rooting to prevent root rot. Keep the rooted bonsai in a cool, well-lit place, but pay attention to shading when it is hot and strong, and do not touch the roots to prevent the roots from loosening and affecting wound healing.
Generally, the root diameter of 0.51 cm is more suitable when filling the root. If the root diameter is too large, the joint scar will be large and it is difficult to heal. The cutting interface should not be peeled too deeply or too deeply, otherwise it will be difficult to bind, not easy to seal, and the survival rate will be low.
