1、 Plant water shortage

1. Reason: in the growth process of Lysimachia christinae, water is very important. If there is a long-term lack of water, the leaves of Lysimachia christinae will turn yellow

2. Treatment method: at this time, water should be supplemented in time. Do not use too much force when watering. You can water slowly around the edge of the flowerpot to make the water diffuse gradually and the soil humidity will be more uniform

2、 Improper ventilation

1. Reason: if Lysimachia christinae is in a sealed environment for a long time, improper ventilation and poor air fluidity, the leaves of Lysimachia christinae will turn yellow

2. Treatment method: improve the ventilation environment. If the outdoor temperature is appropriate, it can be moved to a place with good outdoor ventilation or placed on the balcony

3、 The temperature is too low

1. Reason: if there is yellowing of Lysimachia christinae in winter, it is likely that the root of Lysimachia christinae has been frostbitten, resulting in the emergence of yellow leaves

2. Treatment method: the plant should be transferred to a warm room, and the temperature should be controlled between 16-24 ℃. After a period of relaxation, the leaves will gradually improve
