What should I do if the leaves of the moon flower are yellow, withered and fall off?

What should I do if the leaves of the moon flower are yellow, withered and fall off?

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 use trim small molecule organic carbon for the month. Small molecule organic carbon 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.

The leaves of the moon flower are yellowed and withered and fall off, and the yellowed leaves need to be cut off to save nutrients for the moon season. If it is caused by soil alkalinization, you can water ferrous sulfate solution to Yueji, if it is caused by insufficient water and fertilizer, you need to replenish water and Bika water-soluble fertilizer in time. If it is caused by too much sunlight, move the moon season to a cool and ventilated location for maintenance.

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 yellowing of the leaves may be caused by lack of water and excessive water accumulation, so you can adjust the water and dispose of the rotten roots. It may also be caused by improper fertilization, and should adhere to the diligent application of thin fertilizer, avoid applying raw fertilizer, and water and dilute it in time when fertilizing a lot. It may also be caused by a lack of sunlight, so it should be kept in a sunny place to fully see the light to promote nutrient accumulation.

Or it may be caused by pests and diseases, pay attention to maintaining ventilation, pruning branches and leaves, and spraying pesticides** treatment.

1. Improper watering.

A large number of yellow leaves and leaf loss may be caused by improper watering. Water is needed during the normal growth period of the month, and if it is not watered for a long time, it will lead to drought and lack of water in the soil, causing the leaves to wither yellow, dry out and fall off. If you water too much, the roots will not be able to absorb it all, and water will form in the roots, so that you will not be able to breathe normally, and the leaves will turn yellow.

The water should be adjusted well and the rotten roots should be disposed of.

2. Improper fertilization.

Fertilization will also affect the leaves, if a high concentration of fertilizer is applied, there is no rotted raw fertilizer, or too much fertilizer, it will lead to excess nutrients, causing root burning, resulting in yellow leaves and leaf loss. It is best to insist on thin fertilizer and frequent fertilization, apply thin fertilizer to the roots, and avoid applying raw fertilizer, and water and dilute in time when fertilizing a lot.

3. Lack of sunlight.

If the long-term light is insufficient, normal photosynthesis will be limited, affecting the synthesis and accumulation of nutrients, which will cause the plant to weaken and lose leaves and turn yellow. Keep the moon flowers in the sunny place to fully see the light and promote the accumulation of nutrients.

Starting from the two aspects of dehydration and poor ventilation, we will teach you to water properly, prune and thin branches in time, strengthen ventilation, and avoid the phenomenon of yellow leaves in the month.

The flower buds of the moon season turn yellow and cause them to fall off naturally, and they fall off when you touch them, what is going on?

Causes of yellowing and wilting of the leaves of the moonflowers:

1. Sun exposure.

Reason: Although Yueji likes sunlight, if it is just planted and has not fully adapted to the environment, it has been exposed to strong light in the summer of high temperature, which will cause the Yueji plant to be unadaptable, resulting in the leaves being burned and yellowing, causing the leaves to be yellow and dry.

Solution: For the newly planted plants, don't be in a hurry to see the bright light, you can contact the astigmatism first, and gradually increase the sunlight after adaptation.

Second, the water is rotten roots.

Reason: If the frequency and amount of water are not well controlled when watering the flowers, it may lead to a large amount of water accumulation in the soil, causing root rot, so that the whole growth will be affected, resulting in yellowing and dry leaves.

Solution: Give the flowers reasonable watering, if you water too much, you need to loosen the soil and drain the stagnant water.

3. Improper fertilization.

Reason: If the long-term fertilization is insufficient, it will lead to a lack of nutrients and cause the leaves to turn yellow. If raw or thick fertilizer is applied, it will also cause fertilizer damage in the moon season and cause yellowing of leaves.

Solution: Fertilize according to the growth needs of the flowers, but apply thin fertilizer, and water in time to wash after fertilizer damage.

4. Infection with pests and diseases.

Reason: Pests and diseases in the moon flowers will also lead to yellow leaves and dry leaves.

Solution: Take preventive measures and take measures in time after they appear.

Yellowing and wilting of the leaves of the moon flowers is a fungal disease, improper watering, pest infestation, and lack of nutrients.

1. Fungal diseases

During the growing season, the flowers may suffer from fungal infections and become ill. At this point, yellow spots appear on its leaves, and they gradually spread, eventually turning the entire leaf yellow.

2. Improper watering

Seasonal flowers are more sensitive to moisture, no matter how little or too much watering. If you water too much, it may cause various diseases, and there is also a risk of root rot. If you water too little, the plants will dry up and wilt because they don't get enough water.

3. Pest infestation

There are many pests that affect the growth of peanuts, such as stinging moths, scale insects, aphids, etc. Some pests feed on its leaves, while others suck the sap of the plant, which can cause the plant to lack nutrients and cause the leaves to turn yellow.

Fourth, lack of nutrients

The growth of plants not only needs nitrogen, phosphorus and potassium, but also various trace elements, if the nutrients in the potting soil are lacking, the plant will also have yellow leaves, and according to the lack of nutrients, the performance of yellow leaves is not the same.

Introduction to the moon flowers

Known as the queen of flowers, also known as "moon moon red", it is an evergreen, semi-evergreen low shrub that blooms in all seasons Generally red or pink, occasionally white and yellow, can be used as an ornamental plant, can also be used as a medicinal plant, also known as the moon season.

There are three natural varieties, and the modern moon season flower types are diverse, with single petals and double petals, as well as beautiful flower patterns such as high heart curls; Its colors are bright and rich, not only red, pink, yellow, white and other monochrome, but also mixed color, silver edge and other varieties; Most varieties are aromatic. There are many varieties of Yueji, there are nearly 10,000 species in the world, and there are more than 1,000 species in China.

The natural flowering period is from April to September, and the flowers are large, from the inside to the outside, showing a divergent type, with a strong aroma, which can be widely used in horticultural cultivation and cut flowers. The adaptability of the moon season is strong, cold hardy, drought resistance, regardless of ground planting, potted plants can be, suitable for beautifying the courtyard, decorating the garden, arranging flower beds, with planting hedges, flower stands, easy to cultivate in the moon season, can be used as cut flowers, used to make bouquets and various flower baskets, the flowers of the moon season can extract essence, and can be used in medicine.

It also has good antifungal and synergistic anti-drug-resistant fungal activity. Red cut flowers have become one of the must-have gifts for lovers and have become the subject of love poems.

China is one of the origins of Yueji. The moon season flower is beautiful and beautiful, the posture is diverse, it often blooms at four times, it is deeply loved by people, there are 52 cities in China that selected it as the city flower, and in May 1985, the moon season was rated as the fifth of China's top ten famous flowers.

1.If you overwater, it will make the leaves of the flowers yellow, if the situation is not serious, you only need to water less to return to normal.

2.It is best to maintain more than 4-5 hours of light time, if the light time is not sufficient, it will cause the leaves to turn yellow. Just basking in the sun will solve it.

3.The air is not circulated, that is, the dry and stuffy environment can easily make the leaves yellow in the moon season. Therefore, it is necessary to maintain the flow of air and filial piety.

4.Moon flower is a kind of warm, not easy to expose to the sun, the temperature is too high or too low will also make its leaves yellowing of the present teasing elephant, in summer should be properly bright finger shade, reduce the temperature.

5.There are a lot of flower friends who want to make the flowers grow better, so they will fertilize more, in fact, too much fertilization will cause the phenomenon of burning roots, and then the leaves will also turn yellow.

6.When the moon flower is attacked by pests such as red spider and scale insect, it will also cause the leaves to turn yellow, and regular spraying is required for prevention.

There are several reasons and improvement measures:

1. Overwatering: The watering of the seedlings should be when the soil is dry, if the watering is excessive, it will make the leaves of the flowers yellow, if the situation is not serious, reduce the amount of watering.

2. Light: The moon flowers like light, and should be maintained for more than 4 to 5 hours of light time, if the light time is not sufficient, it will cause the leaves to turn yellow. Proper sun exposure is sufficient.

3. Poor air circulation: The dry and stuffy environment is easy to make the leaves yellow in the moon season. Ventilation should be done promptly.

4. Temperature: The moon season flowers like to warm and noisy, not easy to be exposed to the sun, the temperature is too high or too low will cause the leaves to turn yellow.

5. Fertilization: over.

If the leaves are just yellowing and falling off, it is normal physiological metabolism, don't worry, just remove the yellow leaves. However, if there are other symptoms, it may be caused by pests and diseases.

1. Growth habit: Although the climate and soil requirements are not strict, it is more suitable for loose, fertile, rich in organic matter, slightly acidic and well-drained loam. Sex prefers a warm, sunny and well-ventilated environment.

The optimum temperature for most varieties is 15-26 during the day and 10-15 at night. In winter, when the temperature is below 5, it enters dormancy. Some varieties can withstand low temperatures of -15 and high temperatures of 35; When the temperature lasts above 30 in summer, it enters semi-dormancy, and the plant grows poorly, although it can also give birth to buds, but the flowers have few small petals, the color is dull and dull, and it loses its ornamental value.

2. Pest control:

1) Red spider: The 1500-fold dilution of Gram mite has the best effect on the control of red spider, and the effect can last for more than ten days, but the disadvantage is that it cannot kill mite eggs.

Specific operation: first use the mite, the dilution factor can be slightly higher than the theoretical parameters, a week later, and then use the mite, the dilution ratio is also slightly increased, after two weeks, this cycle again, so that you can basically say goodbye to the mites. For the sake of thoroughness, it is better to prevent and treat it once a month in the future.

2) Powdery mildew:

At the beginning of the disease, the leaves appear to be floating with uneven powdery powder. In the middle period, the area gradually increases; In the later stage, the white powder is thickened, velvety, covered with compound leaves, and soon, the leaf becomes soft and distorted, and the petiole droops and becomes hair-like.

Protection methods: carbendazim, chlorothalonil, methyl trol, etc. are given in turns every 7 days. It can basically prevent the occurrence of disease.

**Method: German Cuibei, Italy Essabao, collection of broad-spectrum fungicides to irrigate roots, once every 5 days, half a month**. ** At the time, especially serious leaves and branches, resolutely cut off, wrap them in plastic bags, and throw them in the trash.

Prevention and control of diseases (3) bacterial infection: Do not cut the leaves are gone, there is no photosynthesis, and the root system will be black.

Prune off the yellow, withered leaves of the flowers. Pour an appropriate amount of water to keep the potting soil moist, and the ambient temperature needs to be controlled at about 20 <>

1.Moisture conditionsWhen 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 conditionsMoon 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 controlThe 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.
