What about the yellowing of the leaves of the latest yellow magnolia

Magnolia is a kind of evergreen flower with strong growth ability and is a very popular potted plant. At present, the planting area of Cymbidium is relatively wide, but there are often a lot of problems in the process of planting, resulting in the decrease of ornamental value. Among them, the yellowing of leaves is more common, so what should be done about the yellowing of yellow leaves? Let's take a look at it with the editor.

1. Rational fertilization

Improper fertilization is the most important problem leading to the yellowing of yellow orchid leaves, and we should follow the principle of applying more and less fertilizer. When fertilizing, we should pay attention to control the concentration, not too concentrated, so as to prevent the excessive concentration of fertilizer from burning the roots of the plant, resulting in obstruction of nutrient absorption, yellowing of leaves and other bad phenomena. And we should also pay attention to the location of fertilization, not too close to the root, to prevent the root directly touching fertilizer, otherwise it will also affect the growth of the root. Finally, we should be careful not to think that what bad phenomenon occurs in Huang Xilan is that it is a lack of nutrition and apply fertilizer casually, which is counterproductive.

2. Rational watering

Water also has a great effect on the growth of Cymbidium, and it is also the main reason for the yellowing of the leaves. If the soil is too dry and leads to insufficient water, it will inhibit the growth of Cymbidium, while too much water will affect the respiration of the roots and cause the leaves to turn yellow. Therefore, in the process of planting, we should pay attention to watering, pay attention to soil water content, such as the production of stagnant water should be timely drainage. In summer and other high temperature environment, it needs to be watered once a day to increase humidity and lower temperature.

3. Pruning in time

Pruning is also essential when planting yellow magnolia. If it is not pruned properly, the branches and leaves of Cymbidium will be too luxuriant, although the appearance may not be affected, but it is too crowded, the permeability is reduced, and the yellow leaves start from the inside and gradually spread to the outer leaves. Therefore, we can not only look at the surface, but also take the branches and leaves apart to observe the growth of the internal leaves. If yellow leaves are found, they should be cut off in time, and then pruned properly to improve permeability and enhance the ornamental value of the plant.

4. Pest control

Huang Yilan is often harmed by some diseases and insect pests, resulting in yellowing leaves. Among them, brown spot is the main disease that leads to the yellowing of yellow orchid leaves. after the occurrence of brown spot, the leaf appears yellowing and wilting in the foreground and gradually withered in the later stage. Therefore, we also need to do a good job in the prevention and control of diseases and insect pests, and often observe the growth of Magnolia. When the phenomenon of yellow leaves is found, remove the diseased leaves in time to prevent transmission, and then find out the cause. If it is brown spot, it should be properly sprayed with Dysen zinc and other chemicals for prevention and control.

The above is a brief introduction to the yellowing of the leaves of Huang Xilan. The harm caused by the yellowing of yellow leaves is very great, which will seriously reduce the ornamental value of Cymbidium.
