Why are the yellow leaves when watered after the drought in the monthly season?

Because the roots die. Since the roots cannot absorb after watering, yellow leaves appear.

It is likely that there is a lack of nutrients, and nitrogen and potassium fertilizers should be supplemented in time to promote the growth of plant rhizomes. It is also possible that the plant has a pest or disease, and a plant-specific insect repellent should be used and sprayed evenly on the leaves of the plant.

This is the monthly season black spot disease, a common disease, which occurs all over the country.

Symptomatic leaves, petioles, twigs, and peduncles can all be damaged, but mainly leaves. There are two types of symptoms: one is the initial leaf surface.

Small reddish-brown to purplish-brown dots appear on the face, gradually expanding into round or amorphous dark black lesions, often with yellow halos around the lesions, radial edges, and lesions about 3-15 mm in diameter. In the later stage, small black particles are scattered on the lesions, that is, the meristem bubble disc of the pathogen. Severe.

When the lower leaves of the plant are yellow, the leaves fall early, causing individual branches to die, such as the black spot of the moon season.

The other is brown to dark brown nearly round or irregularly shaped whorled spots on the leaves, on which black mold grows, that is, disease.

Conidia of bacteria. In severe cases, the leaves fall early, affecting growth, such as elm leaf plum black spot disease.

Pattern of onset. Black spot is the main disease in the moon season, which occurs widely and is serious. The fungus is coiled in dead branches or soil with mycelium or conidia.

Wintering in the soil. The infection began in mid to late May of the following year, and the peak of the disease was from July to September. Conidia are spread and expanded by wind, rain or insects.

Great re-infestation. Rain is the main condition for the epidemic of diseases, and the onset of the disease is early and severe in years with early and more rainfall. Low-lying stagnant water, poorly ventilated, light.

Insufficient illumination, improper fertilizer and water are conducive to the onset of the disease.

Prevention and control methods. Choose excellent disease-resistant varieties.

After autumn, remove dead branches and fallen leaves, and burn them in time.

Strengthen cultivation management, pay attention to plastic pruning, ventilation and light.

When new leaves, spray 500-1000 times of 50% carbendazim wettable powder, or 500 times of 75% leukocomidium, or 500 times of 80% zebze, once every 7-10 days, 3-4 times.

According to this description, there is a high possibility of problems with the root system, is it that the soil of the moon season has not been changed? If you haven't changed it, you can consider replacing it, and the soil quality will not be too good. Prune if there are rotten roots.

It may be nitrogen, or it may be root rot or root disease.

1. Too strong light: The yellow leaves will dry up if they are burned by strong light, and they need to be moved to the scattered light. 2. Too little watering

Water 1-2 times every other week to keep the leaves green. 3. Excessive fertilization: pour a large amount of water into the moon season to reduce the fertilizer content in the soil.

4. Soil discomfort: replace loose, breathable and fertile soil for the monthly season.

1. The light is too strong

Yueji is not tolerant to strong direct light, when cultivating Yueji, if the light is too strong, it will cause the plants to be sunburned, which will make the leaves of Yueji dry and yellow, and it is necessary to move Yueji to a ventilated and breathable scattered light, or do a good job of shading measures for the plants to maintain the healthy growth of Yueji.

2. Too little watering

The moon season needs sufficient water in the growth process, when the breeding month, if the watering is too little, it will lead to the lack of water and the branches and leaves are yellow, you need to water 1-2 times every other week to keep the soil moist, and spray water mist to the moon season when the weather is hot to improve air humidity.

3. Excessive fertilization

When breeding the moon season, if the fertilizer is too little or the fertilizer concentration is too large, it will lead to the plant being burned roots, so that the branches and leaves of the moon season wilt and yellow, and it is necessary to water a large amount of water to the moon season to reduce the fertilizer content in the soil.

4. Soil discomfort

The moon season is suitable for growing in loose and breathable and fertile soil, when breeding the moon season, if the soil is stiff, it will cause the leaves of the plant to dry up and yellow, you need to replace the potting soil for the moon season, you can use humus, sand, perlite mixed to make a cultivation medium.

Summary. Dear, hello, moon flower: known as the queen of flowers, also known as "moon and moon red", is an evergreen, semi-evergreen low shrub, blooming 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.

What should I do if the leaves are dry and yellow?

1.Plenty of watering After the leaves are yellow and dry, you can't water too much, otherwise there will be root rot, so as long as you keep the soil moist and properly control the water.

2.Rush to fertilize When the leaves are yellow and dry, you can't rush to fertilize, otherwise it will directly kill the moon season, and you must wait until the moon season resumes growth and the leaf color becomes healthy before fertilizing. And it should be noted that even if the leaves of the seedlings are not yellow, you can't fertilize it in a hurry, you have to raise it for a month first, and then fertilize it when there is no problem.

3.In addition to fertilization, ferrous sulfate can not be used in a hurry, otherwise it will affect the speed of serving pots in the monthly season, and even lead to the death of the monthly season. Learn to maintain it in this way, and the leaves will be green in the moon season, and the longer they grow, the more vigorous they will be.

1. Improper watering.

Moonflower is an excellent ornamental flower, and if the leaves turn yellow and wilt during the growth period, it may be caused by improper watering. Moonflowers need water during the growth period, but they are not waterlogging tolerant and need to be watered in moderation. If you water too much, the leaves will turn yellow after the root system is damaged, and if you don't have enough water, the leaves will also wilt and turn yellow after lack of water.

2. Insufficient fertilizer.

Moonflowers need fertilizer during the growth period, and they need the right amount of fertilization to promote the growth of flowers and leaves. During the maintenance period, the fertilizer is insufficient, and the branches and leaves of the moon flower lack nutrients, and the branches will be weak, the leaves will turn yellow, dry out and wilt. If there is a lack of fertilizer for the moon flowers, it is necessary to apply Bika water-soluble fertilizer, and the number of fertilization should be adjusted in the later stage.

3. The light is too strong.

Moonflowers like light and are suitable for growing in a sunny environment, but they are not tolerant to strong light. During the summer, if the sun is too strong, if you put it outdoors in a sunny place, the flowers will get sunburned. Under strong light, the leaves of the moon flower will become dehydrated, dry, yellow or wilted, and shade needs to be done during the maintenance period.

4. Pest and disease infestation.

The flower is less resistant to disease and is susceptible to pests and diseases during the growth period. Common pests and diseases of moonflower are anthracnose, black spot, scale insects, aphids and red spiders. After the flowers are attacked by diseases and insects, the growth of the flowers will deteriorate, and there will be lesions or eggs on the leaves, and the leaves will curl, dry, yellow and wilt.

There are many causes of dry leaves and yellow leaves, including malnutrition, lack of water, pests and diseases, and environmental factors such as rotten tung trees. First of all, malnutrition is a common cause of yellowing of leaves in the moon, which may be due to the lack of essential nutrients in the soil, such as nitrogen, phosphorus, potassium, etc. Secondly, the lack of water will also cause the leaves to lose water, resulting in the appearance of yellow leaves.

In addition, pests and diseases can also cause damage to the plants, such as leaf mites, powdery mildew, etc., resulting in yellowing of leaves. Finally, environmental factors such as insufficient sunlight and high or low temperatures can also affect the healthy growth of the moon. Therefore, reasonable fertilization, proper watering, pest and disease control, and providing a good growth environment are the keys to maintaining the green leaves of the moon.
