Matters needing attention in the latest field excavation of red nan tree stump

There are more than 20 species of Chinese Photinia. Its classification is mainly based on leaf type, leaf color, leaf arrangement differences. Different leaf types and leaf colors have different growth conditions and habits. After more than ten years of observation, we found that the ability of Chinese Photinia grown at low altitude was stronger than that at high altitude; the ability of dark leaves was stronger than that of light leaves; the ability of small leaves was stronger than that of large leaves; and the ability of sharp leaves was stronger than that of round leaves.

Some friends just started potted failure, the reason often lies in stump digging or improper primary embryo culture. A pot of good red nan bonsai must pay attention to the protection and maintenance of roots and branches from the beginning of digging piles. If you buy it on the market, you must choose piles with healthy branches (new branches have enough length) and bright skin color. Generally speaking, it is easy to see the advantages and disadvantages of stumps that have been down for more than 4 years. Therefore, it is very important to ask about the age of the mountain before buying.

Phoebe evergreen four seasons, rest period is not obvious, Phoebe adequate nutrition, regeneration ability, in addition to summer, spring and autumn can be dug, before and after the Qing Dynasty is the best. When digging stumps in the wild, pay attention to the following points:

1. Because red nan likes sun, ideal stumps can often be found in barren hills and barren land where it grows in the lee of the sun, mountain roads, cliffs, etc.

2. To dig stumps in the wild, we should choose those old and peculiar, tortuous and root-hanging old piles. The red nan is mostly clustered, and the root blocks are strange. It can be modeled as root instead of dry pile.

3. The red nan can be dug without soil balls. If there is water on the mountain after excavation, the roots of the stumps can be soaked in water. When going down the mountain, the stumps can be wrapped in plastic and transported back. For larger stumps, the roots can be made into fake soil balls with field mud, and then wrapped in plastic and transported back.

4. Treatment of stumps. Cut off the injured roots after digging back the stumps, and saw them off at one time according to the requirements of bonsai at the bottom. But pay attention to the upper branches to stay more than 5cm, because the red nan generally germinates at the lower 5cm of the saw cut. After shaping and pruning, place the stump roots in mud mixed with rooting powder before planting.

5. Tree blank cultivation. Planting sub-planting and potted two kinds, red nan soil requirements are not high, sand loess, vegetable garden soil, pond mud are OK. Nurturing stage, especially in the early stage, must be deeply planted, that is, buried to the root 10cm-15cm above, every morning, middle and evening to spray water on the branches, with shade net to block sunlight, generally about a month can sprout. When the base of the new bud and the leaves turn dark green, it proves that the stump has sprouted new roots, and then the light can be gradually strengthened.
