Making of Black Pine Bonsai

1, in the mining to expand the mining surface, pay attention to as much as possible with soil. Because black pine grows in hillside gravel soil, soil is less, and winter weather is dry, soil moisture is less viscous, so when digging, try to protect the root soil as much as possible. Because the root soil is rich in root mold, it is black pine symbiotic bacteria, which is very conducive to the growth of roots. After digging, plastic bags should be used to make simple bandages in time to prevent soil loss during handling for transplantation.

2. Pay attention to protecting the root system of black pine when digging. Start digging at a place a little farther away from pine trees. First, hollow out the surrounding soil. Keep some main roots as much as possible. Cut off the roots smoothly and cut off the rotten roots. Try to avoid damaging the root system. Especially the side roots, fibrous roots and root systems of black pine tied in sand are weak, so they should be kept as long as possible, especially when digging.

3. The black pine dug back should be buried in time, the sooner the better. A long time will cause the root to lose water and dry up, affecting survival. In order to prevent the root buried too deep, can take high planting, shallow planting, and then add soil from the top cover, no conditions in the field to cultivate in time on the pot.

4. The upper basin of black pine is very important. Before cultivation, first cushion the basin bottom with gravel and tiles to facilitate ventilation and drainage, and then fill the surrounding area with soil. The soil gap is too large, easy to cause frozen roots, pot covered with straw curtain to freeze. It is best to use the original soil on the mountain, or to use the mixed soil prepared from coarse yellow sand, coal ash and yellow mud, with a ratio of 0.5:0.25:0.25. After the pot should be repaired in time, too many branches and leaves will affect the root system water shortage, consuming a lot of water and nutrients.
