The root of banyan tree grows poorly, the number of roots is small, and the growth is biased. It can be repaired by grafting; When the size of the root is uneven, the thicker root can be grafted. In short, all imperfections can be made up by filling the root

Root filling method of banyan

Time

It is generally carried out in plum rain season, and the temperature and humidity are relatively appropriate. After grafting, it can promote the growth of roots

Select the location of the patch

According to the shape of the plant, select the position to be filled with roots. Use a sharp knife to gradually go deep into the wood layer along the surface of the bark at this position, and cut a hole of about 2 cm in the shape of a tongue to ensure the smooth section

Cut root

Cut the roots from the well-growing banyan tree. The color, thickness and length are generally 15 ~ 20 cm long according to the needs of root filling. Cut the roots into wedges, and the section is equivalent to the shape of the root filling position

Root filling

Align the root with the filling position, wrap it with 1cm plastic film, bury the other end of the root in the soil, and then pour water through it. After that, keep the soil moist and soon survive

Precautions

Don't fertilize

Put an end to the application of all external nutrients during root filling to prevent root rot. After root patching, put the plant in a cool place with sufficient scattered light and pay attention to ventilation. Do not touch the root patch to avoid loose interface and affect wound healing

Strength of root patching

The diameter of the root patch is generally about 0.5 ~ 1 cm. If the diameter of the root is large, the wound is difficult to heal. In addition, when cutting the interface, it can not be too deep, which not only makes binding difficult and difficult to seal, but also reduces the survival rate of root filling
