If it is due to the blackening of the leaves and falling off after changing the pot, it means that the operation was wrong during the repotting or the watering was wrong after the repotting!
Try not to remove too much original soil when changing pots, and not too deep when planting!
After changing the pot, you should water thoroughly, and the second watering must be carried out after the potting soil is dry, don't be too diligent!
Do not fertilize the roots of the potting soil in the short term!
It can be placed in sufficient light, no need to shade, and the current temperature and light are still very suitable for its growth!
If its stems don't turn black, it won't die even if all the leaves fall off, so don't worry!
You can see where the problem is, and then you can improve it.

1. The temperature is too low: in winter, move the banyan tree to an indoor temperature higher than 5 degrees. 2. Improper lighting:
Place the banyan tree in a well-lit environment and take shade measures in the summer. 3. Overwatering: Water the soil surface completely dry before watering to avoid waterlogging.
4. Soil discomfort: replace loose and fertile sandy loam every 1-2 years.
Why does the banyan tree lose its leaves.
1. The temperature is too low.
Banyan trees are suitable for growing in a warm environment, when breeding banyan trees, if the ambient temperature is lower than 0 degrees, it will cause the plant to be frostbitten, which will make the banyan tree drop branches and leaves, and the banyan tree needs to be moved to a temperature higher than 5 degrees indoors before winter to maintain the normal growth of the plant.
2. Improper lighting:
Banyan trees like light, but not tolerant of strong direct light, when breeding banyan trees, if the light is too strong, it will cause the plant to be burned and lose leaves, if the light is insufficient, it will make the banyan tree unable to carry out full photosynthesis, it is best to place the banyan tree in a sunny place, and do a good job of shading measures for it in summer.
3. Overwatering.
Banyan trees will lose their leaves in too humid environments, when breeding banyan trees, you need to control the frequency of watering, it is best to water after the soil surface is dry, keep the soil slightly moist, and after watering too much, you need to move the banyan tree to a ventilated and dry environment immediately.
4. Soil discomfort.
When cultivating banyan trees, if you do not replace the potting soil for a long time, it will lead to soil compaction and stiffness, so that the root system of the banyan tree does not breathe well and lose leaves, you need to change the potting soil for the banyan tree every 1-2 years, and when changing the soil, you need to cut off all the rotten and blackened roots of the plant.

Banyan leaf loss is generally a problem of less light, and the most suitable growth environment for banyan trees is humid, warm, and full sun.
Hydroponics are not suitable for exposure to the sun, so you can put it in a brighter place by the window, and it is best to bask in the sun in the morning and evening. If the temperature is high, new shoots can grow in half a month and 20 days.

1. Caused by insufficient light.
Banyan bonsai has lost leaves, most of which are caused by the position of the bonsai and the lack of light. If you put the bonsai in a low-light indoor location, it will generally start to fall off leaves in about 10 days, and the longer you place it, the more serious the leaf loss will be.
Solution: Move the banyan bonsai to the balcony or outdoor environment with sufficient sunlight in time, because the banyan tree likes light, except during the high temperature in summer, the better the light it will grow, the more dense it will grow.
2. Caused by poor ventilation.
Good sunlight and poor ventilation will also cause banyan bonsai to lose leaves, which many flower friends tend to ignore. I thought it would be enough to put it in a brightly lit place, but ventilation is also very important.
Solution: Move the banyan bonsai to a well-ventilated environment, and keep it as close as possible and ventilated.
3. Caused by low-temperature frostbite.
Banyan trees are not very cold-tolerant, if they are still kept outdoors in winter, once the temperature is lower than 0, it is easy to cause the banyan tree to freeze and fall leaves, accompanied by blackening of leaves.
Solution: Once the temperature is lower than 5, it is necessary to keep the banyan tree cold, and the auspicious code that is easy to move will be moved to a sunny and ventilated position indoors, and the inconvenient to move needs to be kept warm with plastic film or other insulation equipment. Although about 0 does not freeze to death, no matter how low the temperature is and long-term freezing, it is easy to cause the death of the plant.

Reason: If the plant is in a state of water shortage for a long time, its branches will lack water, so it will become very dry, so it will fall off when it touches it.
Solution: It should be watered in time, and after the water is fully replenished, the leaves will become firm, so as to effectively alleviate the phenomenon of leaf dropping.
Second, the lack of light reason: if the breeding position is not good, in the case of not seeing the sun, the plant will appear weak to hit him, and it is easy to fall leaves.
Solution: Change the breeding position in time, move it to the sun as soon as possible, and it will not occur under sunny conditions.
Reason: When the temperature is not suitable for growth, the leaves will fall off at the touch, which is a self-protection mechanism of the plant itself.
Solution: It needs to adjust the ambient temperature of its growth, and if the temperature is too high, it should be moved to a cooler place for breeding. If the temperature is too low in winter, it is necessary to move it to indoor breeding in time.

<> reason: Although the banyan tree likes sunlight, long-term exposure to the sun is still relatively unfavorable to its growth, which can easily lead to leaf loss.
Solution: The leaves caused by exposure to the sun are mostly in summer, and the leaves are still green. Proper shade of the bonsai is needed to avoid prolonged exposure to the sun, as well as ventilation and cooling, which can also improve leaf loss.
Causes: Leaf loss caused by moisture problems is relatively common, whether it is too much watering or underwatering is not suitable, so the remedies are not the same.
Solution: Check the dryness and wetness of the soil first. If the soil is too dry and the leaves fall off when touched, it may be caused by a lack of moisture.
In this case, it is necessary to rehydrate the potted plants until the soil surface is moist, and if there is standing water, drain it. If the soil is moist and the leaves fall off a lot, it is possible that the previous water has caused the rotten roots, so it is necessary to check the roots as soon as possible, treat the rotten roots, and then change the soil and replant. In addition, it is necessary to pay attention to the watering principle of the banyan tree, so that it is not dry and not watered, and watered thoroughly.
The soil can be moist, but it can't accumulate water, and it's okay to dry it out a bit.
Causes: Over-fertilization can lead to burns of the roots, leading to defoliation and even plant death.
Choose well-ventilated soil, which can have a certain amount of humus. At the same time, check the condition of the roots and prune them properly. Water in time after planting to observe the situation.
Reason: Frequent movement of the banyan tree is sometimes not a good thing, and environmental changes can cause defoliation.
Solution: After placing the potted plant in a shaded and ventilated place, reduce the movement of it to ensure that it can receive a certain amount of light.
The name of each series of door and window profiles is named according to the width of the door and window frames, not according to the thickness of the profile. For example, the 80 series profile proposed by the landlord is 80 for the width of the door and window frame.
