Exposed roots are also called lifting roots, that is, a part of the thick abundant root system on the upper part of the root system is lifted out of the soil surface. The purpose is to show its old and simple, and to expose some roots to reveal the beauty of its posture. The method is as follows:

Upward formulation

Also known as the pot change method, this method is combined with the pot change, the root system is raised and planted year by year, and then part of the soil is washed away with water to gradually expose the upper root system to the soil surface. If necessary, the exposed roots shall be treated according to the requirements of the picture. If the roots are too dense or redundant, they should be deleted, or the distribution of coarse roots should be adjusted appropriately

Shapei method

Plant the trees in a deep basin, fill the lower part with fertile soil and the upper part with river sand, introduce the absorbed roots of the plants into the lower part, and then remove the river sand in the upper part year by year to expose some coarse main side roots, and then move them into an ordinary Basin, and the roots in the upper part will be exposed. The root finishing is the same as above

Jacketed method

This method is applicable to the tiles or other materials around the upper part of the flowerpot if the height of the flowerpot is not enough, such as thin wood and plastic, so as to improve the height of the flowerpot. When planting trees, fill with soil or fill the lower part with river sand. When the tree absorbs the root system and extends to the bottom, gradually remove the upper soil or river sand, and remove tiles and other objects to expose the upper root system. The removal method of Shanghai bonsai is the same

Other methods

Air rooting

Banyan trees and other trees prone to aerial rooting can be artificially induced to take root. The method is to tie a circle with metal wire at the branch to take root, and cut off the channel for plants to transport nutrients downward. Make the nutrients gather here. Then tie a yarn cloth strip outside the metal ring and make it sag to the basin surface. Then put a bowl of clean water on the basin surface, immerse one end of the sand cloth into the clean water, and the water seeps upward to the metal ring through the sand surface, creating an environment with high humidity and promoting the sagging gas to take root. It should also be noted that before the metal ring falls into the cortex, it should be cut off in time to avoid falling into the cortex and affecting the growth and viewing of trees

Root introduction

During the modeling of young trees, the main root shall be cut off to promote the occurrence of lateral roots and extend laterally to adapt to the cultivation in shallow pots. If the root system of a larger tree is thick, the root system can be fixed with metal wire. The shape is determined according to the shape of the basin and planted in a shallow basin. The root system can also be spread horizontally, paved on a long wooden board and planted in the soil together with the wooden board to make the root system stretch horizontally. The root system cultivated by this method can be suitable for planting in a shallow basin only 1 ~ 2 cm deep. Shanghai style bonsai also uses this method

Attached stone

Attaching stones is to attach the roots of trees to the gaps of stones, or penetrate the roots into the caves of stones to form the form of trees holding stones and passing through stones, which is called "attaching stones". Plant materials and stone materials shall be selected during modeling. Plant materials shall have developed lateral roots and slender. The stone should have good shape, certain momentum, good texture and many crevices. Fix the root system of the tree in the gap or bury it in the soil through the cave, and then take the method of lifting the root, and gradually expose the root system of the stone attached part together with the stone to the soil surface. Plant it into an appropriate basin, that is, form a stone attached bonsai
