The fertilization of banyan tree needs to 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. There is not enough light. The banyan tree grows well in the environment with sufficient light, and the leaf color is greener if it can shade 30-50% of the sun in summer, but it is best not to shade when the temperature is below 32 ℃ to prevent the leaves from falling off.

4. Caused by pests. The main pests that lead to defoliation of banyan trees are red spiders and shell insects, although there are also "thrips". This kind of insect only rolls leaves to absorb juice, which is less harmful than the above two kinds, and thrips are easy to control and can only 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.
