Reason: if the living environment has some changes and the temperature drops suddenly, it will make the plant unbearable, damage its capillary root and make the leaves grow yellow. Too hot and sultry temperature will also have an impact on it.
Solution: pay attention to the change of weather. If the temperature drops greatly, it should be moved to the room for maintenance and placed in a place with good light. If the temperature around becomes higher, put it in a well ventilated place, promote the air circulation, reduce the temperature of the plant
Cause: it is not resistant to humidity and can't stand water logging. If the water is not applied according to the growth condition of the plant, excessive watering will lead to water accumulation in the basin soil, the root system can't bear it, and cause the leaves to turn yellow, which will fall off and rot in serious cases.
Solution: put the basin soil in a ventilated place, speed up the evaporation of water and reduce the degree of water logging. After moderate irrigation plant, frequency according to season and climate change and specific determination.
Cause: the application of fertilizer exceeds the actual demand, causing fertilizer damage, limiting the growth of plants, leaves appear yellow and fall
Solution: according to different conditions of plant growth, the dosage should be less and the concentration should not be too high. If it causes fertilizer damage, it needs to be watered and discharged.
