1、 Causes

1. The light is too weak: the light is very important for its growth. If there is no sunlight or too little to meet the growth, the branches will become thin and the leaves will turn yellow. If you let it go, the plant will gradually weaken until it dies

2. Improper watering: the amount of watering is not adjusted according to different seasons. Although its drought resistance is not very strong, too much watering will lead to ponding in the basin soil, the roots can't breathe, and the upper leaves can't be spared. Forgetting to water for a long time will also lead to this phenomenon

3. The temperature is too low: in late autumn, the temperature fluctuates. If it is placed outside or suffered from a cold wind near the window, the temperature difference between the front and back is relatively large, which may also be caused

4. Improper fertilization: in hot summer and cold winter, the plant has entered the dormancy stage. Continued fertilization will damage the root system and then affect the leaves

2、 Solution

1. The newborn seedlings shall be placed in half shade, and the light shall be supplemented after growing up to ensure that the contact time exceeds 8 hours

2. Increase or decrease the water volume in time according to the situation, and then apply it separately according to different seasons. Once a day in spring and autumn, once a day in the morning and evening in summer, and less in winter

3. Keep warm from autumn

4. During the growth period, nutrients should be applied reasonably, and the dormancy period needs to be stopped
