Generally speaking, bonsai can be changed in spring and autumn every year. Generally, spring is from late February to late April, and autumn is from mid-June to 10.

Effect of changing soil and pots for bonsai

The reason for changing soil and pots in the process of bonsai planting is that plants grow in limited pot soil. After a certain number of years, the fertility is exhausted, the soil layer is hardened, the roots are densely covered, and new roots are difficult to grow. It is necessary to change a larger pot and fill it with new soil to ensure the normal growth of bonsai.

When changing soil and pots for bonsai, we should ensure a certain humidity, the air humidity should be very high, and the temperature should be about 25 degrees. In this climatic condition, the roots of bonsai can be completely exposed to the air when changing soil and pots.

When changing soil and pots for bonsai, water should be stopped for a week first, and then the plants should be taken out of the old pots, taking care not to hurt the roots of the plants.

Step 2 prepare the soil

It is best to use dry mud or river mud instead of bonsai. Before changing pots, prepare dry mud or river mud, which can be divided into coarse, medium and fine. Coarse mud is as big as a thumb. The drain hole is padded with curved tiles, and coarse mud is put at the bottom of the pot to facilitate drainage and ventilation.

3. Planting

Before planting, we should cut off some aging fibrous roots, then put the bonsai in a proper position in the pot, put slightly fine soil around the root of the stump, then cover the surface of the pot with coarse soil, compact the soil, and spray water twice with a watering can.

Maintenance of bonsai after soil replacement

After changing the soil, you need to pay taxes every day and sprinkle water once in the morning and evening. Sprinkle water on rainy days, but don't get wet. Smaller flowerpots can be covered with wet cloth to prevent water transpiration.

Step 2 apply fertilizer
