Those trees in nature, because of perennial rain erosion, have exposed their roots close to the surface and have a unique desolate and quaint charm. In the process of making bonsai, everyone will also expose the roots of bonsai through some techniques, which are collectively called "lifting the roots".

The exposed heel is the face of a bonsai. Bonsai can have one viewing surface or two or more viewing surfaces. Generally speaking, the viewing surface should be regarded as the sunny surface, so that the phototaxis of plants can be used to make it more in line with people's aesthetic habits.

After the organic matter in the basin soil is completely absorbed, the basin soil will become alkaline and harden easily. Turning pots and changing soil can increase the nutrients in the soil, make the soil more loose and breathable, and be beneficial to the growth of trees.

Matters needing attention in bonsai planting

1. The roots of many tree species grow too fast. The roots are coiled around the bottom of the flowerpot and no longer contact with the soil. Some roots begin to age gradually, which affects normal absorption. At this time, if we don't change pots and soil, plants will decline and the growth of stumps will be affected.

2. When turning pots and changing soil, you can also combine flat roots to bend and shape the roots of the stumps with long growth, so that the roots are gradually exposed. This technical treatment is also very important in turning over the pot and changing the soil, and it is also an important reason for turning over the pot.
