Bonsai with stones can be divided into two types: water-attached stones and dry-attached stones. Loose stones, such as water-absorbing stones and sand stones, are mostly used to attach water stones and make holes where trees need to be planted. Most of the newly formed trees are used. First, introduce the roots into the cave, fill the cave with broken mud, compact the soil and roots with bamboo poles, spray the soil and stones through with a watering can, and then put them in a shallow basin and a cool place. Spray water on the stone trees every day to keep the humidity. After the tree sprouts, it can see the sunrise and gradually adapt to the sunshine.
Dry sticking stone method is to use hard stones, such as Yingde stone (various textures), to embed tree roots in artificial crevices (see figure), use Fujian tea, elm, gypsophila paniculata and other tree species with long roots to pick leaves, clean up the soil at the roots, introduce the tree roots into the crevices according to the texture of the stones, and then tie them up with iron wires. In order to prevent the roots from being damaged, you can first pad the sawdust covered with rubber to make the roots closer to the crevices, then put the stone tree on the basin soil and bury the fine roots of the tree in the human soil. The initial curing method is like plastering stone, but don't let the west oblique sunlight shine directly on the root system of stone crevices, so as to avoid burning the root system after the stone absorbs heat.
Generally speaking, banyan trees should be used as bonsai for bouldering.
Plants can't be changed after being stuck on stones, so you must think carefully before making them, and choose the right stones and trees with the right shapes.
