1、 Factors causing

1. The supply of water is inappropriate. It has high requirements for water, so it can't be watered too much or too little. Because too much will cause the root of the plant to be blocked by water and cannot grow, and too little will make it have no water to absorb, so it will dry up and die

2. Diseases and pests will attack the leaves and other places of the plant, and some will directly absorb plant nutrients, making it grow poorly and the leaves fall down

3. The temperature in spring is still relatively low and not very warm, especially in early spring, so we need to pay attention

2、 Remedial measures

1. If there is too much water, you need to take it out of the basin, cut off the damaged parts of the root system and clean it with water, and then apply some medicine to the wound to help it recover. After drying it, it can be replanted

2. If pests are found on the plant, it is necessary to spray the disease location in time to eliminate the insects, and then move it to a place with wind and light for growth

3. It can't stand a certain cold, so it needs to be moved to a warm place for growth. Although it's spring, the temperature is still relatively low, so it needs to be kept warm
