The reason why the leaves of Artemisia angustifolia turned yellow

Primrose is a kind of Primulaceae plant, which is widely distributed in China. As a kind of potted plant, it is welcomed by many people because of its high ornamental quality. And money grass also has a variety of effects, such as heat-clearing and detoxification, diuresis and stone removal. Therefore, there are still many people who breed it now, and when it comes to farming, the leaves of Artemisia mandshurica often turn yellow. What is the reason for the change in the leaves of Artemisia angustifolia? Let's take a look at it.

1. Light discomfort

Although the growth of Artemisia mandshurica has a certain demand for light, it is generally astigmatism. If the growth of Artemisia angustifolia is not bright enough, it will affect the photosynthesis of Artemisia angustifolia, resulting in the decrease of chlorophyll in leaves, resulting in poor growth and the phenomenon of yellow leaves. However, if it is exposed to strong light for a long time, it will burn the leaves and cause the yellow leaf phenomenon. Therefore, we should pay attention to maintain a suitable lighting environment and provide sufficient scattered light. In summer, we should pay attention to do a good job of shading to prevent the sun from shining directly on the leaves.

2. Improper watering

Artemisia przewalskii needs a lot of water to grow, and it also prefers to grow in a more humid environment. Therefore, when we cultivate Artemisia angustifolia, we should pay attention to do a good job of watering. If the soil is too dry and not enough water, then the leaves of Artemisia angustifolia will wilt due to lack of water. But we should also pay attention to control the amount of watering, if too much watering causes the soil to accumulate water. Then the root of Artemisia angustifolia will also be retted by water, resulting in root rot, unable to absorb water and nutrients, thus affecting the growth of Artemisia angustifolia. Therefore, we should water reasonably according to the actual situation, and water thoroughly every time to ensure the normal growth of Artemisia angustifolia.

3. Lack of nutrition

The growth of Artemisia angustifolia needs to consume a lot of nutrients, so fertilization is also indispensable when raising Artemisia angustifolia. If there is no timely fertilization, the soil is too barren, then the money grass will have fallen leaves, yellow leaves and other bad phenomena because of the lack of nutrients for growth. Therefore, we should according to the growth of Artemisia angustifolia, reasonable topdressing, provide balanced and adequate nutrition. At the same time, it is also necessary to control the amount of topdressing, not to apply too much fertilizer, too much heat to cause money grass fertilizer harm to burn roots, there will also be the phenomenon of yellow leaves.

4. Poor ventilation

Poor ventilation is also a major reason for the yellowing of the leaves of Artemisia angustifolia. In the cultivation of Artemisia angustifolia, we should create a good permeability growth environment for it. If the air flow is poor, it can easily lead to hypoxia and affect the respiration of Artemisia angustifolia. And the air quality is poor, the temperature and humidity will also be improved, which is very disadvantageous to the growth of Artemisia angustifolia, and it is easy to appear yellow leaf phenomenon. Therefore, we must pay attention to the culture environment of Artemisia angustifolia, maintain good ventilation and avoid yellowing leaves caused by poor ventilation.

The above is a brief introduction to the reason why the leaves of Artemisia angustifolia turn yellow. That's all for today's introduction. This article is for reference only. I hope it can help you all.
