1、 Increase temperature

1. Reason: Rieger Begonia is a typical tropical flower, which likes to grow and bloom in a warm and hot environment. If it is placed in a place with too low temperature for a long time when it is about to bloom or has already bloomed, it will lead to the problem of falling buds and flowers

2. Treatment method: at this time, we need to help it raise the temperature and control the ambient temperature above 10 ℃. In this way, the problem will be improved after breeding for a period of time

2、 Increase humidity

1. Reason: too dry environment and insufficient humidity are also the reasons for its buds and flowers. Because it prefers humidity, it cannot maintain a good growth state in a dry environment

2. Treatment method: at this time, use a watering can to spray water around it, or place a humidifier around it to improve the humidity of the air

3、 Excessive watering

1. Reason: when curing it, you can't water it too much. Otherwise, the water it cannot absorb in time will stay in the soil and soak its roots. If the root system has problems, it means that the supply of water and nutrients has problems. Without the support of water and nutrients, plants will naturally fall buds and flowers

2. Treatment: dig out the plants from the old soil and cut off the rotten roots. Then plant it in new soil with strong drainage capacity, control the water for a period of time, and wait for it to recover
