Causes and treatment methods of yellow leaves of purple magnolia

Magnolia Magnolia, also known as Magnolia, Magnolia, etc., is a unique flower plant in China. It is widely distributed in the south of China, and its ornamental value is relatively high, and it also has a certain effect. Therefore, there are still many people planting purple magnolia, but when planting purple magnolia, the leaves often turn yellow. So what is the reason for the yellow leaves of purple magnolia? What are we going to do? Let's take a look at it.

1. The growth of root system is blocked.

The hindrance of root growth of Magnolia is the main reason for yellow leaves. The waterlogging tolerance of Magnolia is very poor, if there is stagnant water in the soil, it will seriously affect the root growth. It leads to the lack of nutrition and water absorption of Magnolia, and the lack of nutrition in leaves, which leads to yellow leaves. Therefore, we should pay attention to control the water content in the soil, if it produces stagnant water, it should be discharged in time, and then reduce the amount of water, so that it can be restored as soon as possible. Control the number of watering and the amount of water, watering about 4 times in the whole growing period of Magnolia.

2. Poor drainage performance

Poor drainage performance is the main cause of soil stagnant water, in the soil with good drainage and irrigation, the general stagnant water phenomenon is relatively less. On the contrary, if the drainage capacity is not good, it is easy to appear the false appearance of lack of water in the soil, resulting in too much watering, resulting in poor growth and yellow leaves. Therefore, if it is potted purple magnolia, then we must check the drainage and irrigation performance of the basin soil, if the drainage and irrigation is poor, then we should change the soil in time. The soil is mainly sandy, and there should be drainage holes at the bottom of the flowerpot to improve the drainage capacity of the flowerpot.

3. Lack of light

Light is very important for the growth of Magnolia. Magnolia likes to grow in an environment with plenty of light. If it is exposed to low light for a long time, it will affect the photosynthesis of Magnolia, resulting in gradual chlorosis of leaves and gradual appearance of yellow leaves. Therefore, when we plant purple magnolia, we should pay attention to improve the light time and intensity. To provide sufficient light for purple magnolia, we must not let purple magnolia in a dark environment, affecting the growth of purple magnolia.

4. Diseases and insect pests

Diseases and insect pests are also one of the main causes of purple magnolia yellow leaves. Diseases and insect pests will harm the leaves of Magnolia magnolia, inhibit the growth of leaves, resulting in unable to absorb sufficient nutrients, resulting in yellow leaf phenomenon, and serious diseases and insect pests will lead to plant death. If there are diseases and insect pests, then it is necessary to timely check what diseases and insect pests are, and prescribe the right medicine to prevent the spread of the disease. And they should have some knowledge of pest protection and do a good job of prevention.
