What to do if the yellow leaves fall off the leaves in the moon season, and how to remedy the yellow

Yuejihua has the reputation of "the queen of flowers", is one of the top ten famous flowers in China, there are many varieties, blooming in all seasons, it is a very ornamental flower, the flowers are fragrant when flowering, so it has won the favor of many people. Flowers like a warm and moist growth environment, like light, suitable for planting in loose and fertile and rich in organic matter in the slightly acidic soil, many flower farmers in the process of breeding the moon, there will be leaf yellowing and wilting phenomenon, then from the water conditions, light conditions, temperature control, fertilizer management and pest control and other aspects to analyze the causes and solutions of this phenomenon.

1.Moisture conditions.

When watering the moon flowers, you should control the amount of watering, and you can only water after the potting soil dries up, if you water too much, it will cause the leaves of the moon flowers to turn yellow and wilt, and you only need to reduce the amount of watering and watering frequency appropriately to solve this phenomenon.

2.Lighting conditions.

Moon flower is a light-loving plant, it is best to maintain 4-5 hours of light every day, insufficient light will lead to the phenomenon of yellowing and wilting of leaves, and the solution to this problem only needs to increase light.

3.Temperature control.

The moon flower is suitable for growing in a warm and humid environment, and the indoor temperature should be controlled at 20 -25 when breeding, and the temperature is too high or too low will affect the growth and development of the plant, resulting in yellowing and wilting of the leaves. To solve this phenomenon, it is necessary to provide shade in the summer and control the indoor temperature in the winter when the temperature is too low.

4.Fertilizer management.

In the growth process of the flowers, we should follow the principle of thin fertilizer and frequent application, too much fertilizer will not only not promote the growth of the flowers, but will burn the roots of the plant because of the excessive use of fertilizer, resulting in yellowing and wilting of the leaves, to solve this problem only need to control the amount of fertilizer.

5.Pest control.

When the moon flower is attacked by pests such as red spider and scale insects, the leaves will turn yellow and wilt, and in order to solve this phenomenon, it is necessary to spray with an appropriate amount of insecticides.

1. Regulate the soil.

The moon flower prefers slightly acidic soil, and it is watered with tap water for a long time, and the root system is affected after the soil is alkalized, which will make the leaves of the moon season yellow and wither and fall off. If it is caused by soil alkalinization, it is necessary to cut off the dead leaves and water the ferrous sulfate solution for the monthly season. Ferrous sulfate solution can regulate the acidity and alkalinity of the soil, which is conducive to the growth of the monthly root system.

2. Replenish water.

Yueji needs to have sufficient water during the growth period, and the Yueji is in a state of water shortage for a long time, and the lack of water will make the leaves wilt and yellow. If there is a lack of water in the moon, you need to water the moonseason in time to replenish water for the leaves. During the summer period, it should be noted that when the air is drier, it is necessary to spray the leaves with water 1 3 times a day to moisturize.

3. Reduce light.

During the growth period, under strong light, the flowers and leaves will be burned by the scorching sun, which will make the flowers and leaves wither and yellow. If it is caused by too much light, it is necessary to reduce the leaves with severe sunburn and move the leaves to a cool and ventilated location for maintenance. During the summer months, you can avoid the bright midday light and fill in the light when the light is weak.

4. Reasonable fertilization.

Sufficient fertilizer is required before the growth period, and the lack of nitrogen fertilizer in the early growth period will cause the leaves to appear yellow, dry up and fall off. If there is a lack of nitrogen fertilizer in the monthly season, it is necessary to supplement the fertilizer in time, and thin fertilizer needs to be applied frequently during the growth period. Nitrogen fertilizer can promote the growth of branches and leaves, and also facilitate the formation of chlorophyll.

1. If you are infected with black spot disease in the moon season, you should prune off all the residual branches and rotten leaves to leave healthy plants;

2. Potted plants should be placed at a distance to enhance ventilation and avoid bacterial infection between each other;

3. Clean all the fallen leaves to create a clean and pollution-free environment and reduce the risk of germs;

4. During the treatment period of the moon season, watering only watering potting soil does not spray leaves, reducing air humidity, because sprinkling water mist may also cause infectious bacteria;

5. Spray leaves can be disinfected and sterilized with chemicals, such as carbendazim, zebze, flusilazole, etc.;

6. In order to promote the new growth of the moon season and enhance the resistance of the moon season, you can fertilize it, use the flower meet microbial nutrient solution, the moon season liquid fertilizer, pure organic cane sugar molasses fermentation, dilute with water and water around the root system and pot soil, which can promote the flowering of the long leaves of the moon season.

There are many different types of yellow leaves, pathological yellow leaves, physiological yellow leaves, and fat deficiency yellow leaves.

The condition of yellow leaves and defoliation of moon flowers may be caused by soil compaction, so it is necessary to loosen the soil regularly during the growth process of moon flowers to avoid soil compaction. The yellow leaves of the moon flower may also be caused by overwatering, so it needs to be transferred to a ventilated and cool place for maintenance to speed up the evaporation of water. It can also be caused by an attack of pests and diseases, in which case it is necessary to spray insecticides on the leaves**.

The condition of yellow leaves and defoliation in the monthly season may be caused by soil compaction, so it is necessary to mix humus, pastoral soil and gravel into loose and breathable soil during the breeding season. In addition, it is necessary to loosen the soil regularly during the growth process of the moon season to ensure that the roots of the moon season have good aeration.

The appearance of yellow leaves at the roots of the moon season may also be caused by overwatering. If water accumulates in the soil, the roots of the moon season will not be able to breathe properly, and the yellow leaves will fall off. Therefore, it is necessary to reduce the frequency of watering in the maintenance of the month, and can wait until the soil is dry before proper watering and moisturizing, and the demand for water in the winter season is low, and watering can be stopped.

If there is a yellow leaf loss in the monthly season, it may also be infected with pests and diseases. At this time, it is necessary to spray insecticide on the leaves of the moon season to kill the pests on the surface of the moon season. In addition, it is also necessary to prune off the dead and diseased branches on the moon season to reduce the loss of nutrients and improve the air permeability of the moon season, thereby reducing the probability of disease.

If too much fertilization will cause the roots of the moon season to be burned, if the fertilizer is too little, it can not meet the nutrient needs of the moon season, so in the process of maintaining the moon season, you can sow a rotten organic fertilizer every 1 month to supplement nutrition, so that the moon season can grow and develop healthily.

Causes and solutions for yellow leaf loss in the moon season:

1. Disease invasion: After being attacked by powdery mildew and leaf spot, the leaves will not only turn yellow, but also fall off. Attention should be paid to spraying the agent in a timely manner and insisting on the use of the drug.

2. The environment is hot: If the plant is in a dark and stuffy environment for a long time, its growth state will deteriorate, and the leaves will fall off after a long time. And it is also easy to breed germs, so it is necessary to strengthen the ventilation of the breeding environment.

Causes of yellowing of leaves:

1. Improper watering: If you water the moon season too much, its roots will rot if it is soaked in water, and then its leaves will turn yellow and dull. Dehydration will also cause the leaves to turn yellow, and the edges of the leaves will dry out.

It is necessary to water reasonably, do not have excess water in the pot, and should not be too dry, and try to maintain a slightly moist state.

2. Unreasonable fertilization: When fertilizing, if you use fertilizer that has not been decomposed or fertilizer with too high concentration, its roots will be burned, and its leaves will turn yellow. When applying fertilizer, it is necessary to cook the fertilizer, and the concentration of the fertilizer should be low, and it is best to dilute it before use.

Some of the problems of yellow leaves are caused by improper breeding, and some of them are natural metabolic phenomena.

1. Metabolic yellow leaves in the monthly season.

Metabolic yellow leaves are characterized by occasional yellowing of old leaves. In early spring, when the moon season germinates, the temperature is often very unstable, high and low, so the moon season grows very slowly, these leaves experience unstable temperature, coupled with the rapid growth of the spring season, the bottom of these old leaves, receive little sunlight, poor ventilation, it is easy to yellow and fall off, this is a natural metabolic phenomenon, do not worry. As long as the yellow leaves are cleaned up in time, you can do it.

2. Watering too many yellow leaves.

The most feared of the yellow leaves of the moon season flowers is the yellow water, once the excessive watering causes the dull roots and yellow leaves, it is more difficult to do. The moon flower is a neutral flower, neither too wet nor too dry, watering must be dry and watered thoroughly, see dry and wet.

If there is more watering and the root phenomenon occurs, there will be a large area of yellow leaves, and some old leaves and new leaves may produce yellow leaves, which is mainly judged by checking the humidity of the potting soil.

3. Too arid yellow leaves.

Yellow leaves will also appear if the moon flowers are too dry, and the yellow leaves caused by drought are mainly manifested as a large number of old leaves at the bottom of the yellow and falling off, and at the same time, the potting soil will be found to be very dry. For the yellow leaves that appear in drought, as long as the yellow leaves are cleaned up in time and the water is slow.

4. Infectious diseases (black spot disease).

If the moon season is not properly maintained, it is easy to get black spot disease, and black spot disease will also cause a large number of yellow leaves to appear in the moon season. The main manifestation of black spot is the appearance of black or brown spots on the leaves, which are accompanied by yellowing and shedding of the leaves in severe cases. The leaves that fall from the month of infection with black spot disease must be cleaned up, and they also need to be sprayed with fungicides such as mancozeb, carbendazim, and mycloconazole**.

The methods of defoliation treatment of yellow leaves in the monthly season are: controlling the amount of water, providing light, controlling insect pests, scientific fertilization, and loosening the soil.

1. Control the amount of water.

At this time, it is necessary to loosen the soil with a shovel, put the plants in a ventilated place, and let the water flow out quickly when maintaining the moon flowers.

2. Provide light.

In the process of cultivating the moon season, it should be provided with 6 hours of light time every day, and the summer is used to shade the moon flowers.

3. Pest control.

The yellow leaves may be due to insect infestation, so the plants need to be moved to an open area and sprayed with a diluted carbendazim solution to prevent the pests on the flowers from continuing to breed.

4. Scientific fertilization destroys the calendar.

When cultivating moon flowers, you can not apply fertilizer with too high concentration, you must dilute it with water and then water, and the fertilizer must be rotted, do not apply raw fertilizer, otherwise the branches and leaves of the moon flowers will wither yellow.

5. Loose soil.

If the soil is compacted and the roots are not breathable, it will also cause the yellowing of the leaves, and in severe cases, it will also cause the death of the plant. At this time, the soil needs to be loosened.

The yellow leaves fall off in the moon season, learn to prune correctly, the branches are luxuriant, and the flowers burst into pots.
