It may be that the plant suffers from algal spot, when Milan is infected with algal spot, it is necessary to remove the diseased leaves in time, and move the plant to a well-ventilated and sunny location for maintenance, or it may be that powdery mildew causes white spots on the leaves of the plant, you can use a rag dipped in white vinegar, gently wipe the leaves, and then put the plant in a ventilated and sunny position to dry.
Milanese seedlings are more shade-tolerant when they are young, and prefer sunlight when they grow up; Prefer warm, humid climates and are afraid of cold; It is suitable for growing in fertile, loose, humus-rich slightly acidic sandy soils. Milan is very sensitive to low temperatures, and a short period of sub-zero temperatures can cause plant death.
Precautions for planting in Milan2. Light: Milan should be properly shaded in the seedling stage, and it should be fully exposed to light when it grows up, usually planted in the sun, and can be placed on the balcony if it is raised, so that it can fully receive light.

There is a layer of wax on the outside of this scale insect to protect them, and it is difficult for the agent to penetrate into it, and it is difficult to prevent and control. They attach to leaves and branches to suck the sap of plants, resulting in poor flower growth and a less ornamental appearance of flowers.
So how to control scale insects? There are more insects in the picture, which are more serious, and can be controlled according to the following methods:
Mix 500 parts alcohol with water, then use it to rinse the branches and leaves;
2. Rinse with water after 10 minutes;
3. Finally, use 1 ml of Qianbaiji Ruili mixed with 500 ml of water, spray on the branches and leaves, spray until the water drops, and then pour the remaining liquid medicine into the soil.
Do the above every 5-7 days, 3 times in a row, and the scale worm will die.
The above is this time, flower friends have other questions, you can send a private message in the background, and Qianbaiji will do its best to answer for you.

The white spots on the leaves of Milan are pathogens that produce spore-borne infections. Therefore, the diseased branches and leaves should be cut off as soon as possible, and it is best to burn them. Avoid the residue of germs, which can lead to secondary **.
The main cause of algal spot disease is poor ventilation. It is most likely to occur in Milan where indoor farming occurs, so it is necessary to strengthen air circulation. The first is to change the growing environment and place it on the balcony or windowsill to avoid being too close to other plants.
The second is to prune the branches and leaves that are too dense to ensure that the inside is well ventilated. At the same time, dampness is also the key to the parasitism of germs, so it is necessary to loosen the soil properly, or put desiccant in the room to reduce the humidity.
In the early stage of the appearance of vitiligo, it can be treated with Bordeaux liquid or stone sulfur mixture. Drug spraying has certain limitations, generally only spraying to see the white patches, but there are some transmission of tiny germs that cannot be seen. If the condition is severe, it will only treat the symptoms but not the root cause, and it will be a second time.
When watering, care should be taken not to let the soil get too moist, which can cause the growth of germs. At the same time, fertilization should also be balanced, and organic fertilizer can effectively improve the disease resistance of plants. Don't be biased in applying phosphate fertilizers, focusing only on its flowering and neglecting its health.

1. Prune off diseased leaves.
White spots on Milan leaves are a pathogen that can produce spore-borne infections. Therefore, diseased branches and leaves should be cut off as soon as possible, preferably by burning. Avoid residual germs that can lead to secondary **.
2. Ventilation and humidity reduction.
The main cause of algal spot disease is poor ventilation. Indoor farming is most likely to occur in Milan, so it is necessary to strengthen air circulation. 1. Change the growth environment, put it on the balcony or windowsill, and avoid getting too close to other plants.
Secondly, prune the branches and foliage that are too dense to ensure good internal ventilation. At the same time, humidity is also the key to pathogen parasitism. It is necessary to loosen the soil properly or put desiccant in the room to reduce the humidity.
Stove envy. 3. Drug prevention and treatment.
In the early stage of vitiligo, Bordeaux liquid or stone sulfur mixture can be used for prevention and control. Drug spraying has certain limitations. Generally, it can only be sprayed on the white patches that are seen, but some of the tiny germs that spread cannot be seen. If the condition is severe, it will only treat the symptoms but not the root cause, and it will be ** again.
Fourth, water and fertilizer control.
Be careful not to let the soil get too wet when watering, as this will cause the growth of germs. At the same time, fertilization should be balanced, and organic fertilizer can have a hidden effect to improve the disease resistance of plants. Don't apply phosphate fertilizer, only focus on its flowering, but ignore its health.
