What if the leaves of the latest Milan flowers turn yellow?

Milan is a flower native to southern Asia, which is now distributed in tropical areas all over the world. In China, it is mainly distributed in subtropical areas such as Yunnan, Liangguang and Fujian. If family farming is concerned, it is usually cultivated in pots. Many people will encounter the problem of yellowing Milan leaves when raising Milan. below, the pro-agricultural network will introduce to you how to do the yellowing leaves of Milan flowers.

If we want to understand the treatment of Milan leaves after yellowing, we must first understand the causes of Milan leaves yellowing. Here, the pro-agriculture network introduces you to five points, involving temperature, ventilation, soil, light and watering. They are all related to daily maintenance. Let's take a look at them in detail.

1. Low temperature

If Milan's leaves turn yellow in winter, then the first thing to consider is whether it is the effect of low temperature, which is the most common cause of Milan's yellowing. 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.

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.

Second, improper watering

Milan is a wet plant, but if it is not changed for a long time, the nutrients in the soil will be reduced, and the air permeability will also be weakened. after watering, the roots will be in a wet state for a long time, and respiration will be suppressed. it will lead to rotting roots, resulting in yellowing and shedding of leaves. If the root is found to be necrotic, you should stop watering immediately. If the pot soil is already very wet, you can take Milan off the pot and replant it.

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.

Third, lack of light

The growth of Milan needs sufficient light, and if there is not enough light, it will lead to less nutrients produced by photosynthesis, so that the leaves will yellowing and fall off. If the lack of light in Milan leads to the defoliation of the yellow leaves, we have to move Milan to the sun immediately and rotate the direction every month to let Milan receive light evenly, so that the yellow leaves will gradually recover.

IV. Soil alkalinity

Milan needs slightly acidic soil to cultivate, the soil in the south of China is more in line with the growth of Milan, but in the north, the soil is alkaline, if it is used to cultivate Milan, it will cause the leaves to turn yellow. The simplest solution is to change the pH of the soil. Alum fertilizer and 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. Poor ventilation

Most plants need to grow in an environment with good air quality and good ventilation, and if Milan grows in places where the air is not convective for a long time, it is also prone to yellowing leaves. If family farming, we should pay attention to more windows and ventilation, and cut off the overdense branches and long branches in time to ensure good lighting and ventilation.

These are the reasons and solutions for the yellowing of Milan leaves introduced by the pro-agricultural network, hoping to bring some help to you. When Milan blossoms, it has a pleasant fragrance and can be placed in the living room or study at home, pleasing to the eye and refreshing.
