What is the operation procedure of bonsai repotting? What should I pay attention to?

Depot the bonsai, the potting soil should not be too wet or too dry, need to remove part of the old soil, replace it with new soil, do not touch the roots when removing the soil, find rotten roots, be sure to cut off, but also properly prune the branches and leaves of the bonsai.

If it's an extra-large pot, you'll need more than one person to assist. First of all, it is necessary to loosen the soil, so that there is a gap between the pot soil and the pot wall, and you can also use objects to hit the pot wall to separate the pot wall from the pot soil, tie the plant rhizome with a rope, and several people pull out the plant and change the soil.

To put newspaper on the ground (this can be omitted if it is outdoors), put the pot upside down on the newspaper, and then use a leather hammer to hit the wall of the pot, you need to pay attention to the strength here, and at the same time use a slender shovel to reach into the place where the soil and the wall of the pot are afraid to touch to dig out the soil, and finally pull out the plant and change the soil.

<>1, repotting and soil can generally be selected in 2-4 months (in the south in 2-3 months, in the north 3-4 months), a few days before the repotting of the soil is not watered, and then change after the pot soil is half dry, because the pot soil is too wet, the viscosity between the pot wall and the soil is too large is not conducive to the overall detachment of the soil ball, and too dry will affect the growth of plants. 2. First draw a circle with an iron nail (as deep as possible) near the soil on the ridge pot wall, so as to facilitate the overall detachment of the soil ball, the soil ball shows that the root system has been spread around the pot wall, and the nutrients in the original pot soil have been absorbed by the plants.

3. After the soil ball is taken out, the soil ball can be gently broken, and the root system can be slowly and thoroughly peeled off the old soil ball; It can also be rinsed with water to make all the roots come out; Then carefully look at the state of the roots, and remove the old roots and bad **. Then the transverse branches, weak branches and overlapping branches on the inner surface of the plant are also cut off, and the functions of pruning the branches are: first, to reduce the transpiration of the leaves to facilitate the recovery of the root system of the plant as soon as possible; Second, the canopy of the plant that has grown for many years also needs to be trimmed.

4. If the branches are potted directly without pruning, the plant may fall to adapt to the damaged root system (or do not germinate new branches for a long time), which is called the "potting stage". Before the pot, the water outlet at the bottom of the basin can be stacked with two tiles (the "in" zigzag tile is good), which is done in order to: first, keep the water outlet unobstructed and prevent water rotting roots to the greatest extent; The second is to increase the air exchange in the potting soil, which facilitates the respiration of the root system and provides the air for the plants to maintain the optimal growth state.

5. After the tiles are stacked at the outlet, you can spread a layer of organic fertilizer soil (or nutrient soil (or nutrient soil) at the bottom of the pot (depending on the size of the pot), put the pruned plants in the middle of the pot, and leave a gap of 2-3 cm between the plants and the pot. Fill the reserved void with organic fertilizer soil (or nutrient soil), and if the fill is too full, at least 2-3 cm must be reserved to facilitate watering and water storage.

8. After completing the above procedures, water enough root water at one time, and the potted soil will be completed.

Bonsai soil change pot time.

Generally speaking, bonsai can be changed in spring and autumn every year, generally from late February to late April in spring, and from mid-October to mid-November in autumn. Absolutely.

Bonsai for soil and pots.

The reason for bonsai planting is that the plant grows in the limited potting soil, and after a certain period of time, the fertility is exhausted, the soil layer is erected and destroyed, the root system is dense, and it is difficult for new roots to grow. Therefore, it is necessary to change a larger pot and install new soil to ensure the normal growth of the potted scenery. When changing the soil and potting of bonsai, a certain humidity should be ensured.

The air humidity should be very high, and the temperature should be around 25 degrees. In this climate, bonsai can completely expose the roots to the air when changing soil and pots.

Bonsai soil exchange method.

1.When removing the bonsai and changing the soil and repotting, you need to stop the water for a week, and then remove the plant from the old pot, taking care not to hurt the roots of the plant. 2.

Soil bonsai replacement is best done with dry mud or river mud. Before changing pots, prepare dry mud or river mud, which are divided into three types: coarse, medium and fine. Thick thumb as big.

The drainage hole is cushioned with curved tiles, and the bottom of the basin is cushioned with coarse-grained soil to facilitate drainage and ventilation. 3.Before planting, you need to cut off some of the aging fibrous roots, then place the bonsai in the appropriate place in the pot, spread slightly finer soil around the roots of the stump, cover the pot with coarse soil, compact the soil, and then spray the water twice with a watering can.

Bonsai is maintained after soil change.

1.After watering the bonsai and changing the soil, you need to pay taxes every day. Sprinkle water once in the morning and once in the evening.

You can also sprinkle water on rainy days, but don't get wet. Smaller pots can be covered with a damp cloth to prevent water transpiration. 2.

After fertilizing the bonsai and changing the soil, because it is spring, it is the season when the bonsai begins to grow rapidly, so it is necessary to fertilize in time, apply n, p, and k particles in the potting soil, cover the soil, and sprinkle water the next day. 3.After pruning the bonsai and changing the soil, tidy up the roots of the plants.

Roots that are too thick and too long should be cut off, which can promote the bonsai to grow some better roots and increase the number of roots. 4.After changing the soil, the bonsai should be kept indoors for maintenance.

It should be placed indoors in a place with strong light. Use lights at night, increase lighting time, and pay attention to timely ventilation.

A few points to pay attention to when changing soil:

1. Plants basically begin to sprout after Arbor Day, and it is best to change pots at this time.

2. Pay attention to protect the roots when changing the soil, and start knocking on the edge of the pot with a small shovel to loosen and separate the root system and the pot.

3. Turn the pot and the plant upside down and knock the pot at a place where a high jujube can collide, and the plant will fall down along with the mound due to inertia.

4. Change to a large pot, and then water it thoroughly, and the stool eggplant is conducive to rooting.
