Measures: If it is because of excessive watering, it needs to be moved to a ventilated place with scattered light to loosen the soil for it, speed up the evaporation of excess water in the basin soil, and make the basin soil dry again. If it is because there is too little watering, it is necessary to appropriately increase the amount of water and increase the frequency of watering. When you see that the surface of the basin soil is dry, water it. Every time you water it, it should be thoroughly watered to wet the soil, but there should be no water accumulation.
2. reasons for adjusting the light: when the light is too strong, it will burn the leaves of the plant and make it fall off easily. Too little light will make it difficult for branches and leaves to carry out normal photosynthesis to synthesize nutrients, and it will easily fall off after a long time.
Measures: If the light is too strong, it needs to be moved to the shade for maintenance first, and then moved to the environment with scattered light for maintenance after it has recovered. If there is too little light, you can move it to a place with plenty of light, and you need to shade it when there is strong light.
3. Reasons for washing the soil: If you don't pay attention to the dosage and apply too much fertilizer during the maintenance process, and the root system of the plant can't absorb so many nutrients in time, a lot of fertilizer will remain in the soil, thus damaging the root system and slowly falling the branches and leaves.
Measures: Wash the soil with plenty of water, dilute the fertility in the soil, let the excess fertilizer flow out of the drainage hole of the flowerpot, and then put it in a cool and ventilated place to make the soil dry again. If the situation is serious, the roots need to be taken out, washed with water, dried, pruned and replanted.
