What if the leaves of Prunus mume turn yellow and fall off?

Prunus przewalskii, also known as Iron Begonia, is a trailing shrub plant with many branches. Tiger thorn plum is highly ornamental, and it is more common in shopping malls and parks all over our country. And the roots, stems and leaves of Prunus angustifolia have certain medicinal value and are loved by many people. However, when planting thorn plum, the leaves often turn yellow and fall off. So what should I do if the leaves of Prunus mume turn yellow and fall off? Let's take a look at it.

1. Drainage root trimming

Before dealing with the yellowing and shedding of the leaves of Prunus mume, we must first understand what causes it. If there is stagnant water in the soil caused by too much watering or rain, it will lead to rotten roots in the roots of Prunus mume, leading to yellowing and shedding of leaves and so on. So if it is caused by this reason, then the whole plant should be taken out in time, the roots should be examined and the rotten roots should be cut off. It is then sterilized in carbendazim and then dried and planted in dry and clean soil. At ordinary times, we should also pay attention to do a good job of drainage, give priority to prevention to avoid stagnant water in the soil.

2. Strengthen ventilation

The yellowing and shedding of Prunus mume leaves may also be caused by poor air circulation. Because the air circulation is poor, it will lead to a decrease in indoor oxygen content and poor air quality. Thus, it affects the respiration of the leaves, inhibits the growth of the leaves, and leads to the yellowing and shedding of the leaves. Therefore, we should pay attention to maintain a culture environment with good permeability and strengthen ventilation management. If the temperature is too low, then ventilation should be based on the premise of heat preservation. It should be done at noon when the temperature is slightly higher to prevent frostbite caused by blowing cold air into the plant.

3. Temperature control

Temperature is also one of the main reasons for the yellowing and shedding of the leaves of Prunus mume. The tiger thorn plum likes to grow in a warm environment, and its cold resistance is very poor. If the temperature is too low, it will cause frostbite of the plant, yellowing and shedding of the leaves if it is light, and death of the plant if it is heavy. Therefore, we should pay attention to control the temperature, especially in winter, to do a good job of cold protection and heat preservation. The lowest temperature can not be lower than zero degrees, but in winter, thorn plum will enter the dormant period, dormant leaves are also normal.

4. Lighting management

Light is also very important for the growth of Prunus mume. Especially for the leaf development of Prunus angustifolia, Prunus przewalskii is a kind of plant with long sunshine. If the light is not enough, it will cause poor growth, affect the photosynthesis of leaves and reduce the accumulation of photosynthetic matter, resulting in yellowing and shedding of leaves. Therefore, we should pay attention to the tiger plum in a place with sufficient light for maintenance, but we should pay attention to proper shading in summer to avoid excessive light causing burns to the leaves. In spring and autumn, the plants can be exposed to all-day sunshine to ensure the normal growth of tiger prickly plum.

The above is a brief introduction to how to change and fall off the leaves of Prunus mume. That's all for today's introduction. This article is for reference only. I hope it can be helpful to everyone.
