The reason why the leaves of the moon season start to yellow from the tip of the leaf and the yellow

1. Improper watering.

The young leaves are dull and dark yellow, the old leaves do not change obviously, the branches are thin and yellow-green, and the growth of new shoots is abnormally atrophied, which indicates excessive watering. Yellow is manifested as dry and withered leaf tips or edges, and old leaves wither and fall off from the bottom upwards, while the growth of new leaves is relatively normal, indicating a lack of water in the month.

Solution: Overwatering, depot the flowers in a ventilated and cool place, and wait for the soil to dry before putting them back into the pot. When watering in the future, pay attention to the watering principle of "do not dry and do not water, and watering will be watered thoroughly".

2. Nutrient problems.

Nitrogen fertilizer promotes leaf growth, phosphorus fertilizer promotes flowering, and lack of fertilizer in the month can lead to malnutrition and disease. Or the use of unrotted fertilizer, resulting in root burning.

Solution: Apply well-rotted organic fertilizer, such as chicken manure, cow manure, cake fertilizer, etc.; Due to the lack of nutrients in the small pot, the large pot is immediately replaced and filled with nutrient soil. Do not apply unrotted organic fertilizer and large doses of chemical fertilizer, so as not to cause the plant to burn the roots and wilt and die.

3. Viral yellow leaves.

The moon season has been attacked by the virus, and the leaves will not stretch and the leaves will be yellow.

Solution: Spray solvents such as virus grams and gram poison dew in time for prevention and control, and pay attention to comprehensive maintenance and management in the future to ensure the health and growth of plants.

4. Potting soil problem.

Potting soil compaction leads to poor soil permeability, and plant roots have difficulty breathing, which affects plant growth.

Solution: Insert more than a dozen holes in the pot with bamboo skewers to ensure that the roots are breathable.

5. Poor ventilation.

In the environment of insufficient ventilation and stuffy air, it will also make the leaves of the moon flowers yellow and yellow spots.

Solution: Therefore, it is necessary to put the moon flowers in an environment with good air circulation and ventilation to breed.

The yellowing of the tips of the leaves in the moon season is not the cause of fertilizer, it is the lack of it, don't make a mistake!

The water is big! Ventilation is not good.

The yellow leaves at the bottom of the moon flower may be caused by soil conditions, water and fertilizer application, light and pests and diseases, etc., the growth of the moon flower can not be in a long-term humid environment, generally the plant should be placed in a ventilated environment to grow normally, when the yellow leaf phenomenon occurs, the cause should be found according to the specific situation, and then make timely treatment.

If the watering is too much water accumulates in the soil, the plant can not absorb it, which will lead to root rot for a long time, which will lead to yellowing of the leaves at the bottom of the flowering plant, so it should be watered properly, and the next watering should be carried out after the soil is completely dry.

2. Poor ventilation

When the plant grows too densely, without timely pruning, the ventilation performance between the leaves will deteriorate, and some leaves are also prone to yellowing when growing in a humid environment for a long time, so the plants should be properly pruned, keep the leaf distance, and at the same time place the plants in a ventilated environment for maintenance.

3. Insufficient light

Seasonal flowers should not grow in strong sunlight, but the necessary light is also important for the plant. Light can provide the plant with the conditions needed for photosynthesis, if it grows in a low-light environment for a long time, the plant cannot photosynthesize normally, and the surface of the plant leaves will turn green.

4. Pest and disease infestation

General fungal diseases and spider mites are the most susceptible to the invasion of the moon flower, pay attention to observe whether there are small dots on the surface of the leaves of the moon flower, and it is red, purple or brown, so that the end of the month is infected with fungal disease, to cut off the infected leaves of the moon flower in time, and keep the soil has good drainage.

The yellowing of the leaves from top to bottom may be caused by soil compaction, which needs to be replaced in time to plant with strong loose ability, and the roots can be irrigated with orange peel water, which can maintain acidic conditions, and if there is a lack of nutrients, a small amount of nitrogen fertilizer can be applied, and if aphid diseases occur, they can be used with soapy water**.

The solution to the yellowing of the leaves from the bottom up.

1. Replace the potting soil.

If there is a problem of potting soil in the breeding process, it will lead to yellowing of the leaves from the bottom to the top, so at this time, it is necessary to choose the flower soil with strong loose ability to re-plant, and a layer of cinder can be spread on the bottom of the pot before planting, so that the ventilation capacity of the pot can be increased during the breeding process.

2. Maintain acidic conditions.

The yellowing of the leaves from top to bottom may be caused by excessive soil alkalinity, at this time it is best to use orange peel water for watering, which can maintain the acidic conditions of the soil, but watering should not be too frequent, and it can be watered about 2 times a week to avoid the phenomenon of rotten roots.

3. Top dressing nitrogen fertilizer.

The yellowing of the leaves may also be caused by the lack of fertilization for a long time, and a large number of nutrients in the leaves are missing, so a small amount of Trim granule compound fertilizer needs to be applied at this time, and the fertilization can be diluted by watering, which can promote the absorption of nutrients by the roots, and the potting soil needs to be replaced once for 1 2 years of monthly growth.

4. Insect pests.

If the moon season is poorly ventilated for a long time, the plant is susceptible to aphid disease, you can spray the plant with soapy water, which can effectively kill the aphids, and it is best to place it in a ventilated environment during the usual breeding, and the air mobility can be strengthened to prevent the production of aphids.

In the newly potted month, the leaves are yellow, what causes it.

Hello, I have helped you find the result; The yellowing of the leaf veins of the moon flower is caused by the following reasons<>

1: Too much water or lack of water: Moonflowers have a high need for water, but excessive or lack of water can cause yellowing of leaves and veins.

If it is caused by too much water clustering, the frequency and amount of watering can be appropriately reduced. If it is caused by a lack of water, it should be watered promptly and the soil should be kept moist. 2：

Lack of nutrients: Lack of nutrients can be supplemented by fertilization. Generally speaking, top dressing is required once a month during the growth of the moonflowers, using fertilizers rich in medium to high nitrogen, low phosphorus and high potassium, such as compound fertilizer or bone meal.

3: Pest and disease infestation: common pests and diseases of moon flowers include black spot, aphid, powdery mildew, etc.

If you find pests or diseases, you can go to the plant store to buy pesticides for spraying**. 4: External environmental impact:

Changes in the external environment, such as insufficient sunlight, overly cold or hot temperatures, and poor air circulation, may cause yellowing of the leaves and veins of the moonflowers. Proper light and ventilation should be provided, while maintaining a suitable temperature. 5：

Soil quality varies: The soil for the moonflower should be fertile, well-drained, acidic or neutral soil. If the soil pH is too high or too low, or the soil is barren, it will also cause the leaves and veins to turn yellow.

Soil testing can be carried out to supplement the required nutrients and adjust the pH to meet the growth needs of the old moon flower<>

1. The branches and leaves are too dense.

Judgment basis: The branches and leaves in the figure grow too densely, and a small number of leaves turn yellow evenly, which is caused by the lack of pruning and the poor ventilation of the branches and leaves.

Solution: This situation is not a big problem, pick off the yellow leaves, and then prune the dense branches and leaves.

2. The water is large. Judgment basis: In the figure, the leaves of the moon season begin to turn yellow from the leaf veins, which is a typical symptom of the roots of the water big stuffiness. As for the root cause of stuffy roots, it may be that the potting soil is not breathable, or it may be too much watering and poor ventilation, which depends on the specific maintenance situation.

Solution: Put this pot in a well-ventilated and sunny place, let the soil dry as soon as possible, and pay attention to less watering in the later maintenance.

3. Fertilizer damage. Judgment basis: In the month above, a large number of leaves suddenly turned yellow uniformly, and according to the description of the flower friend, this situation appeared after fertilization, which is most likely caused by improper fertilization.

Solution: pour a large amount of water in time to dilute the fertilizer to alleviate the pesticide damage; Or directly use sodium fenitol to alleviate fertilizer damage.

4. Insect pests, more typical are red spiders.

Judging basis: The leaves of the moon season are dense yellow-white patches, look closely at the spider webs, look at the back of the leaves with red, black or white dots crawling, this is the red (white) spider harm Zhao Zhao. Spider mites are a particularly difficult insect pest, difficult to control and easy to reverse.

They will hide on the back of the leaves to suck the sap, causing the leaves to turn yellow, fall off when touched, and in severe cases, they will pull the wire and form a net, and eventually the whole plant will die.

Solution: Cut off the yellowed branches and leaves, then spray the front and back of the leaves with 1 ml of linazine resin mixed with 1 liter of water. In addition to spraying, special attention should be paid to the ventilation of the maintenance environment, which is more likely to occur in poorly ventilated environments.

5. The disease is more typical of black spot disease.

Judgment basis: In the picture, the leaves turn yellow and there are black spots on the leaves, and the leaves fall off when they are touched, which is black spot disease. Black spot disease is a very common disease in the moon season, which can cause yellow leaves, fallen leaves, and even light rods, and in severe cases, lead to death in the moon season.

Solution: Cut off the yellowed leaves first, and then use benzpyrazole spray for control, 1 capsule mixed with 500ml of water, spray on the front and back of the leaves, and spray until the branches and leaves drip water. Spraying once every 5-7 days, spraying 3 times in a row can curb the spread of the disease, but the leaves that have turned yellow have undergone local tissue necrosis, and there is no way to restore the green color.

1. High temperature exposure.

The leaf tip is dry, and yellow smudge patches appear on the leaf surface after exposure to the sun, mostly due to exposure to the sun and dehydration (first starting from the leaf tip to wither), short-term high temperature sunburn, remember to shade properly, especially in the noon-afternoon period.

2. Normal metabolism digging ruler.

The bottom of the old leaves are yellow, and it is all yellow, it is a normal replacement of old leaves, you can remove the yellow leaves, the upper half of the leaves are normal and fine, if you are worried, you can sprinkle some Aolu 318S fertilizer near the roots.

3. The water is stuffy and the roots are stuffy.

Normal leaves are yellow, the color is irregular, and the pot surface is wet for a long time, which may be watery roots, and usually accompanied by bacterial diseases, such as black spots, powdery mildew, etc. Remember to ventilate and control water properly.

4. Fattening. After fertilization, a large area of leaf tips yellow, there is a burning feeling, is the reason for too much fertilization or fertilizer, you can take out the fertilizer, liquid judgment high body fertilizer can lift the pot, water watering, the fertility in the soil flush out, serious directly change the soil.

5. Yellow leaves of black spot disease.

After rain or watering is not clean, the soil is not clean, there are fungi, it may cause fungal yellow leaves, black spots are one of them, remember to remove the leaves with black spots in time, clean the pot surface, the soil surface near the roots, spray Chibi to inhibit bacteria.

Summary. Hello, the yellowing of the leaves of the newly planted moon flowers is caused by insufficient nutrition. Recommendations:

Top dressing outside the roots. Fertilization in this method is mainly to make up for the lack of nutrients in the soil, so as to solve the problem of lack of fertilizer in the plant, so that the seedlings grow fast and the flowers and fruits grow hypertrophied. Extra-root fertilization is to spray the dilution of fertilizer directly on the leaf surface of the plant with a mist, so that the nutrients can penetrate into the leaf tissues through the leaf epidermal cells and stomata, and then be transported to the whole body of the plant.

It is recommended to use Bayliss moon plants to spray the foliage of the moon flowers regularly, the nutrient absorption is faster and more sufficient, and the leaf spot, leaf blight, stem rot and other diseases of the moon flowers are removed, so that the moon flowers are fully nutritious and no longer yellow and withered leaves, and there is also the effect of promoting flowers and flowers. Regular use of Bayliss moon plant care can also prevent the occurrence of leaf spot, leaf blight and stem rot, and ensure that the leaves are green and the flowers are gorgeous.

Hello, the pure loss and yellowing of the leaves of the newly planted moon flowers are caused by insufficient nutrition. Recommendation: Root topdressing.

Fertilization in this method is mainly to make up for the lack of nutrients in the soil, so as to solve the problem of lack of fertilizer in the plant, so that the seedlings grow fast and the flowers and fruits grow hypertrophied. Extra-root fertilization is to spray the dilution of fertilizer directly on the leaf surface of the plant with a mist, so that the nutrients can penetrate into the leaf tissues through the leaf epidermal cells and stomata, and then be transported to the whole body of the plant. It is recommended to use the Belize Yuechang pants wild plant to spray the leaf surface of the moon flower regularly, the nutrient absorption is faster and more sufficient, and the leaf spot, leaf blight, stem rot and other diseases of the moon flower are removed, so that the moon flower is fully nutritious and no longer yellow and withered leaves, and there is also the effect of promoting flowers and flowers.

Regular use of Baylis moon plant care can also prevent leaf spot, leaf blight, and stem rot from growing, and ensure that the leaves are green and the flowers are gorgeous.

There is also a situation that the water hurts the root in the cause of the yellowing of the new leaves of the moon flower, and the more common one is the water hurts the root. Many of our flower friends have found that the original boring acres of the root of the moon season, after the rescue, the new shoots, the leaves are easy to appear in this tender yellow state, if not timely measures, further development of new leaves will also wither. This is actually because of root damage, resulting in malnutrition, if you do not pay attention to water control when maintaining the cover, the potting soil is still very wet, and the new shoots will gradually wither in the moon season, until the branches are black throughout the month.

In the face of this kind of water root seedlings, what we need to do is to change it to a smaller pot, because the root system of the moon season is rotten, the leaves are gone, and the consumption of water is very small.
