The banyan tree likes the environment with plenty of sunshine, good ventilation and humid air, which mainly grows in southern China and Southeast Asia. Here are the reasons why the banyan tree lost its leaves.

1. Improper watering: the banyan tree must adhere to the principle of not drying and watering thoroughly. The drying here means that the surface of the basin soil is dry, not thoroughly. Of course, even if it is dry, it will not cause great damage to the banyan tree in a short time, because the leaves of the banyan tree are thick and small, and have a certain degree of drought resistance.

2. Improper fertilization: the fertilization of banyan trees should be carried out by applying thin fertilizer frequently to avoid the application of high concentration chemical fertilizer or unfermented mature organic fertilizer, otherwise it will cause fertilizer damage, the light ones will lose their leaves and the heavy ones will die.

3. Lack of light: the banyan tree grows well in the environment with sufficient light, and it grows well indoors for a long time (such as being kept indoors for more than half a month in summer), poor ventilation, lack of light, long-term non-drying of basin soil, lack of air in the soil and rotten roots, resulting in fallen leaves.

4. Improper soil change: if the soil is changed in the peak growing season, due to the damage to the roots of trees, the upward transmission of nutrients is inhibited, and lack of supply will lead to defoliation. It should be noted that some unscrupulous merchants will change land at will regardless of the consequences in order to increase their appearance before sale.

5, temperature reason: if the summer high temperature period can shade 30-50%, the leaf color is more green, but when the temperature is lower than 32 ℃, it is best not to shade, lest the leaves fall off. The weather begins to warm up in spring, but the cold wind in early spring is dry and piercing, so if you put a winter banyan tree indoors, it will become very delicate, especially for banyan trees cultivated indoors with higher temperatures, if they come out of the room too early to resist the cold wind. Leaves will fall as soon as the wind blows.

6. Insect pests: red spiders and shell insects are the main pests that cause defoliation in banyan trees. Although there are also "thrips", this insect only rolls leaves to absorb juice, which is less harmful than the above two kinds, and thrips are easy to control. Only curly leaves can be removed and destroyed. The individual red spider is relatively small, and the general harmful part is the back of the leaf, which is caused by poor ventilation and dry air. The whole plant can be washed with water and sprayed with special mites, such as mites, acaroid mites and so on. The harmful parts of shell insects are mainly stems and petioles, with different size and color, round and oval in shape, and generally do not move, but they are harmful and need to be prevented and treated in time. They can be wiped clean with a toothbrush or dishcloth, or 0.2% solution of detergent and essential oil can be sprayed, or pesticides such as methamphetamidophos are sprayed with good results.

If in the growing period, there are a small amount of yellow leaves, shedding, is a normal metabolic process.
