1、 Lack of moisture

Lotus leaf is an aquatic plant, which cannot be separated from water. If it is short of water during its growth, it will turn yellow leaves, so it should be watered in time. No matter in which growth stage, the soil should be moist. Water can be poured into the basin soil of breeding as soon as possible, so that the leaves will recover their color soon

2、 Lack of nutrients

Its yellow leaves are largely due to lack of nutrients. During the growth period, more nutrients are consumed, so it is necessary to supplement fertilizer in time. If you don't apply fertilizer for a long time, the root system can't absorb the proper nutrients and can't provide them to the leaves, and it will turn yellow slowly. The compound fertilizer solution should be applied every other month in the peak growth season, or the rotten rice washing water can also be used to meet the demand

3、 Lack of light

Its growth is inseparable from light. If it is placed in the dark for a long time, the leaves cannot carry out photosynthesis, and it will turn yellow slowly over time. Move to a place with astigmatism. When the temperature is high, just block the light in time. It is recommended to put it in the outdoor astigmatism place, with good ventilation environment, which is more conducive to its recovery

4、 Infectious disease

If the environment provided during management is not suitable, such as poor ventilation and lack of light, it is easy to be infected with yellowing disease, and the leaves will turn yellow. The maintenance methods shall be changed in time, more ventilation shall be provided and management shall be strengthened. We should also dispose of the diseased leaves as soon as possible and spray chemicals to prevent and control the disease
