How to repot a miniature bonsai? Detailed correct method and steps
Repotting a bonsai is mainly done to improve the growing space for the plant's roots, so that the roots do not develop problems due to limited space, and after repotting new nutrients can be added, thereby better promoting plant growth. Not only do ordinary bonsai need regular repotting, even the seemingly very delicate miniature bonsai also need timely repotting. For plants with strong adaptability and sprouting ability that grow quickly, repotting is generally done once every 1-2 years; for relatively slow-growing deciduous bonsai that have already taken shape, repotting is generally maintained at once every 3-5 years.
Bonsai repotting work is generally chosen to be carried out in spring, and this is also true even for miniature bonsai. This is because most bonsai generally require relatively mild temperatures in spring and autumn, and at least repotting in a suitable climate environment often causes much less harm to the plant, so after transplanting it is easier for the plant to establish itself and survive, and to resume normal growth. So, how do you repot a miniature bonsai? Today, the editor will share with you the repotting process for miniature bonsai.
1. Preparatory work
First we need to prepare the tools and materials needed for the repotting work, mainly including the miniature bonsai, a shallow pot, scissors, wire pliers, metal wire, binding wire, scissors, soil, chopsticks, etc. Only when the preparatory work is sufficiently thorough can you be calm and at ease during the specific operation. In short, we need to prepare in advance all the tools and materials that will be used.
2. Treating the new pot
First, the selected new flower pot needs to have multiple drainage holes at the bottom, then line the inside of the pot bottom with a layer of wire mesh, then pass the metal wire through the drainage holes and the wire mesh, and then secure the wire mesh at the pot bottom. But the size of the metal wire needs to be flexibly chosen according to the size of the flower pot, the tree roots, and the drainage holes. You can first bend the metal wire into a U shape and pass it through the wire mesh and the largest drainage hole at the pot bottom, then pull the two ends of the metal wire that extend outside the pot bottom outward in opposite directions until the wire mesh at the pot bottom can be secured. Finally, inside the pot, use a section of metal wire to pass through the wire mesh so as to secure the bonsai tree later.
3. Removing from the pot and clearing soil
In order to make it easier to remove the plant from the pot and avoid causing too much damage to the roots of the bonsai tree, the original author suggests using chopsticks to gently tap off the old soil adhering to the tree roots after removing it from the pot. But it is not necessary to scrape off all the soil; you only need to poke off the outer layer of soil, because retaining some necessary old soil can allow the plant to establish itself faster and survive better. Then cut off the excessively long lower portions of the roots. This mainly means cutting off the old, weak, fine roots at the lower end; of course, if there are thick, long roots that hinder potting, they also need to be shortened as well.
4. Potting process
First pour part of a granular medium such as akadama soil into the new pot, then plant the bonsai tree into the new pot according to factors such as the tree's form and personal preference. Then cover with a layer of potting soil, and tighten and secure the protruding metal wire with wire pliers. This is because securing the bonsai tree tightly often allows the soil and roots to come into fuller contact, which is more conducive to the plant establishing itself and surviving after repotting. Finally, use chopsticks to gently tamp the potting soil to avoid creating too many gaps in the pot.
5. Cleaning up debris
After completing the repotting work, we also need to promptly clean up the soil and debris scattered on the pot rim and outer wall, so that the bonsai looks neater and more attractive. At the same time, note that whether repotting or potting for the first time, it is often necessary to develop good cleanup habits and do the finishing work well. Do not, just because the earlier work was done well, end up leaving some unnecessary flaws at the end.
At this point, the repotting work for the miniature bonsai is completely finished. But it can be seen that the repotting process for miniature bonsai is also largely the same as for ordinary bonsai; the key is to handle the details well and operate carefully and cautiously. After all, miniature bonsai are much more delicate than ordinary bonsai, relatively more difficult to handle, and because the selected tree form is small, the root system is relatively weaker, so extra caution is needed during the repotting process.
