What are the reasons for the yellowing of Lysimachia nummularia leaves?
Lysimachia nummularia (creeping Jenny) is a plant in the Primulaceae family, widely distributed in China. Because of its high ornamental value, it is very popular as a potted plant. It also has various medicinal effects, such as clearing heat and detoxifying, promoting diuresis and expelling stones. Therefore, quite a lot of people grow it now, and when growing it, the leaves of Lysimachia nummularia often turn yellow. So what causes the leaves of Lysimachia nummularia to change color? Let's take a look below!

1. Inappropriate lighting
Although the growth of Lysimachia nummularia has a certain demand for light, it is generally mainly indirect light. If the growing light is insufficient, it will affect the photosynthesis of Lysimachia nummularia, leading to a decrease in leaf chlorophyll, thus causing poor growth and the appearance of yellow leaves. But if it is exposed to strong direct light for a long time, it will scorch the leaves and also cause yellowing. Therefore, we should pay attention to maintaining a suitable light environment and provide sufficient scattered light. In summer, attention should be paid to shading work to prevent direct sunlight on the leaves.
2. Improper watering
Lysimachia nummularia needs a large amount of water during growth, and it also prefers to grow in a relatively humid environment. Therefore, when growing Lysimachia nummularia, we should pay attention to watering well. If the soil is too dry and the water is insufficient, the leaves of Lysimachia nummularia will wilt and turn yellow due to lack of water. But we should also pay attention to controlling the amount of watering. If too much water is given and causes waterlogging in the soil, then the roots of Lysimachia nummularia will also suffer from root rot due to too much water, causing the roots to rot and be unable to absorb water and nutrients, thereby affecting the growth of Lysimachia nummularia. So we should water reasonably according to the actual situation, and each watering should soak through to ensure the normal growth of Lysimachia nummularia.
3. Insufficient nutrients
The growth of Lysimachia nummularia consumes a large amount of nutrients, so when growing Lysimachia nummularia, fertilizing is also indispensable. If fertilizer is not applied in time and the soil is too poor, then Lysimachia nummularia will show various adverse phenomena such as leaf drop and yellow leaves due to a lack of nutrients needed for growth. Therefore, we should apply fertilizer reasonably according to the growth condition of Lysimachia nummularia, providing balanced and sufficient nutrients. At the same time, we should still control the amount of fertilizer applied, and not apply too much, to avoid excessive fertilizer and too much heat causing fertilizer damage and root burn to Lysimachia nummularia, which will also cause yellow leaves.
4. Poor ventilation
Poor ventilation is also a main reason for the yellowing of Lysimachia nummularia leaves. When growing Lysimachia nummularia, we should create a growth environment with good air permeability. If the air circulation is too poor, it is easy to cause oxygen deficiency and affect the respiration of Lysimachia nummularia. Moreover, poor air quality will also increase temperature and humidity accordingly, which is also very unfavorable to the growth of Lysimachia nummularia and very easily causes yellow leaves. Therefore, we must pay attention to the growing environment of Lysimachia nummularia, maintain good ventilation, and avoid yellowing of leaves caused by poor ventilation.
The above is a brief introduction to the reasons for the yellowing of Lysimachia nummularia leaves. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
