What to do with the leaves of Milan flowers? the causes and solutions of yellowing leaves of Milan flowers

Milan likes warm and sunny places, its leaves are green and shiny, the flowering period is long, and it has a high ornamental value. Many friends planted a pot at home, but in the process, it is found that it is particularly easy to have yellow leaves and fallen leaves. In view of this problem, the editor introduces you some solutions.

What if Milan loses its leaves?

1. Adhere to the principle of not drying, not watering and "dry and wet". Generally, water should be watered once every two days, and must be watered thoroughly when watering. It is watered once a day in summer and autumn, and every 2-3 days in winter and spring.

2. Adhere to the principle of frequent application of thin fertilizer, apply fertilizer once a month, you can also add an appropriate amount of calcium superphosphate in the fertilizer, so that Milan flowers will grow better.

3. The Milan flower was cultured under bright scattered light.

4. Spraying pesticides regularly and controlling diseases and insect pests every 15-20 days.

The reason for the yellowing of the leaves of Milan

1. Low temperature: if the leaves of Milan turn yellow in winter, we should first consider whether it is the effect of low temperature, which is the most common cause of yellowing in Milan.

Milan likes a warm environment, where frostbite occurs when the overwintering temperature is below 5 ℃, and the initial stage of frostbite is characterized by the gradual yellowing of leaves and shedding. Another point is that the cold wind can make Milan's leaves appear yellow leaves overnight.

2. Improper watering: Milan is a wet plant. If it is not changed for a long time, the nutrients in the soil will be reduced and the air permeability will be weakened. After watering, the root system will be in a wet state for a long time, and the respiration will be restrained. It will lead to rotten roots, resulting in yellowing and shedding of leaves.

3, lack of light: the growth of Milan needs sufficient light, if the light is not enough, it will lead to less nutrients produced by photosynthesis, so the leaves will yellowing and falling off.

4. Soil alkali: Milan needs slightly acidic soil to cultivate. The soil in southern China is more in line with Milan's growth, but in the north, the soil is alkaline. If Milan is cultivated with such soil, it will cause the leaves to turn yellow.

5. Poor ventilation: most plants need to grow in an environment with good air quality and good ventilation. If Milan grows in places where the air is not convective for a long time, it is also prone to yellowing leaves.

The solution of Milano Leaf Yellow

1. It is difficult to save Milan if it is frostbitten or blown by a cold wind, which will affect the flowering of the following year and, in serious cases, lead to plant death, so pay attention to the heat preservation in winter.

2. If the root is found to be necrotic, the watering should be stopped immediately. If the pot soil is already very wet, Milan can be removed from the pot and replanted.

In addition, in the high temperature season, the watering is not timely, the basin soil is too dry for a long time, and the leaves will turn yellow in a short time. At this time, do not water enough water at one time, to step by step, so that the plant slowly recover.

3. If Milan's yellow leaves fall off due to lack of light, we should immediately move Milan to the sun and turn the direction every month so that Milan can receive light evenly, so that the yellow leaves will gradually recover.

4. The simplest solution is to change the pH of the soil. Alum fertilizer water can be applied three or five times a year. Ferrous sulfate and other substances are contained in the fertilizer water, which can not only improve the acidity of the soil, but also improve the soil fertility, which can be said to kill two birds with one stone.

5. Family farming should pay attention to more windows and ventilation at ordinary times, and cut off the overdense branches and long branches in time to ensure good lighting and ventilation.

How to survive the winter in Milan

Milan is not tolerant of low temperature. Generally, during the period from Frosts Descent to the Beginning of Winter, you have to move into the room and put it on the sunny windowsill or desktop. The indoor temperature should be kept at 8 ℃ and 10 ℃, with no less than 5 min. If the temperature is too high, tender shoots will grow, reducing adaptability and cold resistance. Plants should not be close to the stove or hearth, the use of plastic cover can adjust temperature and humidity, but need to cut one or two cracks at the top of the cover, so as not to affect the normal growth of temperature and humidity.

The basin soil should be watered when it is dry, but not fertilized. When the weather changes suddenly and the indoor temperature drops below 5 ℃, special measures should be taken to keep warm, such as moving the potted flowers under the table at night, covering the table with cloth curtains and padding grass curtains to keep warm; you can also cover the pots with plastic bags and remove the cover curtains the next day when the sun comes out and move the potted flowers back to the same place from under the table. Where you put it in Milan, you should not open windows for ventilation, so as not to damage the plants by the cold wind.

Milan is native to the tropics and likes warm places. If the temperature is too low, it may even freeze to death, so the cold winter is a great test for it and needs our more careful care. Otherwise, it won't survive. The above editor introduces the method of overwintering, we can try to make it through the winter smoothly.
