1、 Excessive watering

1. Reason: if you pour a lot of water on the swallow's paw when raising it, it may lead to the problem of rotten roots. After its roots decay, the speed of absorbing water and nutrients will be reduced. If the leaves get less water and nutrients, they may turn yellow and fall off

2. Treatment measures: at this time, take the plant out of the flower pot first, and cut off all rotten roots with scissors. Then, it should be planted in new soil with good drainage capacity, and the water should be properly controlled to prevent it from rotting again

2、 Temperature discomfort

1. Reason: if it is kept in too cold or too hot environment for a long time, it will also grow poorly and lose its leaves

2. Treatment measures: at this time, change the temperature of its surrounding environment and keep it between 15-32 ℃. In winter, we should pay attention to keeping warm, and in summer, we should pay attention to shading and cooling

3、 Forget fertilization

1. Reason: when the swallow's paw is in the growth period, it is generally topdressing once every 10 days. If it is planted in poor soil without nutrients and forgets to apply fertilizer, it may also lose its leaves due to lack of nutrients

2. Treatment measures: at this time, it is necessary to appropriately increase the frequency of fertilization to supplement nutrients for it. When applying fertilizer, it is recommended to apply liquid fertilizer, because such fertilizer is easier to be absorbed by the plant
