Generally speaking, spring is the season when most flowers change pots. How to change the pot, and what problems should be paid attention to in the process? Share it with everyone.

How to change pots 0 1 for flower bonsai? The biggest fear of changing pots is to hurt the roots and affect plant growth. So, stop watering before you decide to change pots. When the soil in the flowerpot is dry, dig along the flowerpot to separate the plants from the flowerpot.

Shake off the plants that have been taken out a few times, or peel off the topsoil of some roots by hand to check the growth of plant roots.

If the root system is found to be too long, aging and rotten, it should be pruned.

In addition, on the same old root, if the fine roots grow too densely, they can also be cut off, so that the nutrients absorbed by the plants can be provided for the growth of the upper part of the plants instead of being absorbed by excessive root growth.

02. Soak the plants trimmed with carbendazim in water for about 10 minute, which can disinfect the roots and help the damaged roots recover (if the roots have not been trimmed, this step can be ignored).

03. First, pour one third of the soil into the basin, put the plants in the middle and straighten them; Then slowly return the soil, and compact the soil at the same time, which is beneficial to the close combination of roots and soil and the later growth. Note: Be sure to straighten the plants, and don't be too violent in the process of compacting the soil, so as not to damage the roots.

04. When backfilling, don't fill all the pots. You need to reserve a few centimeters for later growth management such as watering and fertilization. As for the number of centimeters reserved, it depends on the size of the basin. Generally speaking, 3~5 cm is enough.

Finally, pour enough water and change pots (if there is rooting powder, add some rooting powder to the water and stir it evenly, which is beneficial to the rapid recovery of root growth).

Several problems that should be paid attention to in the process of changing pots. First of all, the root system is the key to the growth of any flower. The root system is responsible for absorbing nutrients and transporting them to all parts of the plant for growth.

Generally speaking, unless the root system is seriously damaged, the soil of the root system will be stripped off when changing pots, otherwise the original soil should be brought when changing pots to avoid the bare root system.

Second, the choice of container for changing pots, both new pots and old pots can be used. The size of the container also needs to be determined according to the size of the plant, not the bigger the pot, the better.

Third, changing pots without changing soil is basically equal to changing in vain.

This is because the old potted soil, in the process of plant growth, the nutrients in the soil will be absorbed by plants, leading to the decline of fertility, or because of excessive application of chemical fertilizers, leading to soil hardening and other problems.

The choice of new soil is best decided according to the variety of flowers you plant. For example, cactus, a plant that likes sandy loam, can never be planted on clay loam with poor water permeability and difficult drainage.

In addition, if farmyard manure is added to the new soil, it should be made half a month in advance to prevent the farmyard manure from fermenting and decomposing to generate heat, which will cause the harm of burning seedlings. It is best to expose the new soil in the sun for a few days to kill the eggs and germs in the soil.

In reality, some friends may find that flowers grow well without changing flowerpots. As a result, the leaves of the flowers began to wither and turn yellow after changing pots.

In fact, a common reason for this situation is that seedlings are not delayed, which is a key step after changing pots.

Because plants grow in a new environment, they need an adaptation stage. During this period, the ability to absorb water and fertilizer is weak, and the nutrients absorbed by the roots are insufficient to support the growth of the upper part of the plant.

The practice of delaying seedlings: the plants after changing pots should not be placed in strong sunlight, but in a ventilated and cool place. After about a week, the plants can adapt to the new soil and grow again, and then they can be placed in the original planting place.

In addition, if the leaves on the top of the pot-changing plants grow too luxuriantly, they need to be trimmed to reduce the nutrient consumption of the plants.

5. After changing pots, water should be poured for the first time, and then according to the degree of dryness and wetness of the soil, water should be poured after the soil is dry, instead of every day.

Plants that have just changed pots are not suitable for topdressing. My personal suggestion is that when considering changing pots, farm manure and soil should be added one month in advance, and the sandwich method should be used as the bottom, which is enough to meet the needs of plants after changing pots in the first two to three months. Then topdressing, there will be no obesity problem.

Write at the end: different flowers have different dormancy period, vigorous growth period and flowering period. Try not to change pots during the vigorous growth or flowering period.

Should choose in the germination stage, or early growth stage, at this time, the demand for water and fertilizer is not high, nutrient consumption is not big, and changing pots is not easy to affect its normal growth.

Moreover, it is not necessary to change pots every year, and it needs to be decided according to different flower patterns and different growth conditions.
