1、 Causes of occurrence

1. It may be caused by incorrect water irrigation, so it needs to keep the humidity in the basin between 50% and 70%. Usually, it needs to supplement water once a week, and it needs to spray more water in hot weather

2. It is very sensitive to light. Too little sunlight will make the plant grow disorderly and the leaves wilt. Too much light will make the leaves of the plant dry, sharp and scorched, which will make it sag

3. The amount of fertilizer should not be too small or controlled. Too much will burn the root of the plant, thus damaging the growth of the plant. Too little will lead to its lack of nutrient supply and poor leaf growth

4. The temperature should not be too low. After it is lower than 5 degrees, its growth is in a semi dormant state. If it is lower than zero degrees, the whole plant will be damaged by freezing

2、 Solutions

1. Its illumination time should be kept at least 6 hours of sun irradiation every day, and there is no visible stimulating light irradiation

2. Add water appropriately. If the soil is dry, do not water it, so as not to cause water stains in the loam and rot the roots of the plant

3. Its growth temperature is kept between 5 and 25 degrees, so it will grow well. When the temperature is relatively high in summer, spray more water on it to help it cool down

4. The use of fertilizer does not need to be too diligent. Generally speaking, it is OK to apply fertilizer once every 30 days when the seedlings are growing. Do not apply it to the leaves. Fertilization can be stopped in summer and winter, because the growth is relatively slow at this time
