What s the matter with the yellowing of osmanthus leaves?

<> osmanthus leaves are yellow, probably because too much water was poured into the soil when raising it, causing it to be waterlogged. At this point, you need to move it to a well-ventilated location, dry its flower soil, and control the watering until it recovers. It may also be because of too much fertilization, which causes its root system to be burned out.

At this time, a large amount of water should be poured into the soil to wash away the remaining fertilizer. Dry the soil again and wait for it to recover.

Cultivation methods and precautions of osmanthus trees;

1. Soil: Osmanthus trees are suitable for growing in loose and fertile soil, and can be mixed with humus, garden soil, sandy soil and cake fertilizer, with a ratio of 2:3:3:2. This not only has a certain amount of nutrients, but also has good drainage.

2. Light: The osmanthus tree likes light, so it should be placed in a sunny place to receive sufficient light. However, in summer, it is necessary to provide proper shade and avoid strong light exposure. Seeing more light before flowering is conducive to the differentiation of flower buds.

3. Watering: Osmanthus trees are more sensitive to water, and generally replenish water in time after the soil surface is dry, and watering should be done thoroughly, but try not to have water at the roots.

4. Fertilization: Osmanthus trees need to be supplemented with fertilizer during the growth period, and liquid fertilizer is generally applied once every half a month, so that it can grow better. In addition, apply a little potassium dihydrogen phosphate fertilizer before and after flowering to replenish it with nutrients.

Precautions: When cultivating osmanthus trees, the branches of the osmanthus trees should be pruned regularly, and the old branches, dead branches and weak branches should be cut off; In addition, if you plant in the north, you should pay attention to keeping warm during the winter, you can hand in antifreeze water before winter, and then wrap the trunk with newspaper.

The yellowing of osmanthus leaves may be caused by not watering for a long time during maintenance. At this time, it is necessary to pour some water on it and increase the number of times it is watered during subsequent maintenance to help it replenish water. It can also be caused by too much fertilization.

At this time, the plant should be depotted, pruned off the roots burned by the fertilizer, and then planted in the new soil with no residual fertilizer, and slowly maintained until it recovers. The tips of the leaves of the osmanthus tree begin to turn yellow, which may be affected by the disease. If the environment is not conducive to growth, it may cause osmanthus diseases, such as brown spot, leaf blight, blight, anthracnose, etc., after being infected with the disease, it will invade the leaves, causing the leaf tip to turn yellow first.

Solution: Use sterilized scissors to cut off the diseased leaves on the osmanthus tree to prevent the bacteria from spreading to other branches and leaves, put them in a place with better ventilation conditions, spray fungicidal drugs on the osmanthus tree, spray two or three times in a row, and completely remove the germs. Reason:

If you don't water for a long time, or if you water too much, it will cause the leaf tips to turn yellow.

Solution: When there is a shortage of water, it is necessary to water and supply it in time, control the water in time when there is a lot of water, discharge the stagnant water, and dispose of the rotten roots. Reason: The development of osmanthus trees is inseparable from nutrition, if there is a lack of nutrients or fertilizer damage, it will cause the leaves to wither and yellow.

Solution: Attention should be paid to reasonable topdressing for growth, and nutrients should be balanced and comprehensive. Once fertilizer damage occurs, it needs to be diluted by watering in time.

The yellowing of osmanthus leaves needs to be countermeasures for the cause: if it is caused by an inappropriate temperature, it should be given an appropriate temperature; If it is too much watering, it is necessary to reduce watering, and the soil is not dry and watered; If it is less fertilizer or too much fertilizer, it is necessary to fertilize reasonably; If the soil quality is not suitable, it is necessary to change the soil quality appropriately.

1. Appropriate temperature.

15-28 is the most suitable temperature for the growth of osmanthus flowers, the temperature is too high in summer, if it is not cooled or still exposed to the sun, it is easy to turn yellow. Winter temperatures that are too low and not properly insulated can also cause its leaves to turn yellow. Therefore, when raising osmanthus flowers, you should pay attention to cooling down in summer, you can put it in a cooler place, and you should pay attention to keeping warm in winter, and you can move it indoors.

2. Reasonable watering.

This kind of flower is not resistant to waterlogging, once the water is too much, it is easy to cause its rotten roots, and the rotten roots will have yellow leaves. Therefore, when planting this plant, it is necessary to choose loose soil with good drainage, in addition, the daily watering should not be too frequent, not too much at one time, and watering after the potting soil is dry.

3. Correct fertilization.

If less fertilizer will lead to the yellow leaves of this plant, so we should apply fertilizer reasonably during its growth period, and the water-soluble fertilizer and compound fertilizer of fertile leaf amino acids can be, but it should be noted that the concentration applied should not be too large. In addition, we should change the pot and soil in time to ensure that the potting soil is not compacted and there are enough nutrients in the soil. It is worth noting that you can't be in a hurry when fertilizing, too much fertilizer or too much concentration at one time is not conducive to its growth, and even will cause it to burn roots and yellow leaves.

Fourth, change the soil quality.

Comparatively, it prefers acidic soils. If the soil is alkaline or alkalized, the leaves of this plant may turn yellow. To keep the soil acidic, you can add a little ferrous sulfate or leftover beer when watering, and also pay attention to the fact that the ferrous sulfate solution and beer should be diluted, and the concentration should not be too high.

Most of the reasons for the dry and yellowing of the leaves of the osmanthus tree areMoisture, light, temperature, air circulation, nutrientsHere are five reasons.

If the leaves of the osmanthus tree turn yellow because there is too much water, the amount of water should be controlled, and the soil should not be dried and watered. If it's not enough light, give it 6 to 8 hours a day. If the temperature is not right, adjust it to 14-28.

If the air is not circulating, put it in the air circulation. If there is a lack of nutrients, fertilizer should be supplemented in time.

Osmanthus tree planting method:

1. It is not possible to have more water or less water.

The soil in which the laurel tree is planted must have good ventilation holes, and it is very afraid of too much water. For the maintenance of osmanthus, it is best that the soil is not dry and not watered, and every time you water it must be watered thoroughly. If you water too much, the roots of the laurel tree will turn black and rot, and the tips of the leaves will be brittle and wilted, and then the whole leaf will gradually wither and turn yellow and wither.

Second, the irradiation of light is very important.

3. The suitable temperature grows high.

1. Laurel trees should be placed in a sunny room in winter, so that they can not only spend the winter safely, but also survive the dormant period steadily, and the temperature is best controlled at 5 to 8, otherwise it will lead to the early germination period of buds and leaves, and there will be a series of bad effects.

2. The most suitable temperature for growth should be 25 to 30, and the flowering period is in the crisp autumn, and it is best to control the temperature at 15 to 20, which will lead to the postponement of the flowering period, and above this temperature, the flowering period will be advanced and the flowering period will be shortened.

Fourth, air circulation does not get sick.

The unobstructed air of the laurel tree not only increases the humidity around the potted plant, but also circulates all the bacteria near the leaves, making it less susceptible to bacterial infection.

Fifth, to obtain nutrients tree strong.

The osmanthus tree is also a delicate plant, and a moment of negligence may make it sick, so we can provide it with a decaying propagation fertilizer or potassium fertilizer, such as a water-soluble fertilizer with high potassium macroelements, so that the osmanthus tree can gradually improve its immunity and thrive.

The Chinese mean osmanthus as "noble", "beautiful", "auspicious", "friendly", "loyal man" and "unyielding", "immortal friend" and "cyclamen"; Yu Guizhi is an "outstanding person" and "official career"; Europe and the United States are "glorious" and "honorable". The fragrance of osmanthus is pleasant, it is often seen outdoors in the park, and it is also a very good choice to raise a pot of osmanthus at home, but the problem of yellowing of the leaves will still appear, how should it be dealt with?

1. Soil compaction makes the leaves yellow

Osmanthus prefers a loose soil environment with strong air permeability and slightly acidic pH, and if the soil is compacted, it will affect the growth and the leaves will turn yellow.

Usual maintenance can be watered with fermented rice washing water to neutralize the pH.

2. Normal metabolism makes the leaves yellow

If it's just a few yellow leaves, and it's close to the roots, don't worry too much. That is the normal metabolism of osmanthus, as long as the yellow leaves are modified.

3. Improper fertilization makes the leaves yellow

Osmanthus fertilization is mainly based on phosphorus and potassium fertilizer, followed by other nutrients. The purpose is to make the branches grow thicker and bloom better. However, if the fertilizer is not used properly, it will cause the leaves to turn yellow and burn the roots.

The nutrient solution of Bamboo Green Green Leaf King is mainly aimed at domestic ornamental leaf flowers and plants, with good effect, containing a variety of nutrients, and direct spraying does not need to be diluted, spraying on the leaf surface can also be absorbed, in a certain treasure, a certain duoduo.

The above three points should be paid special attention to, as long as the right medicine can get rid of the distress of yellowing of osmanthus leaves.

What should I do if the leaves of the osmanthus tree are dry and yellow? First of all, it is necessary to determine the cause of yellowing, and then come to ** according to the situation after finding the cause.

The yellow leaves of osmanthus leaves and the wilting of the leaf tips may be due to the strong light, the plants are sunburned, and the strong light in summer must be blocked in time, and water must be sprayed frequently. It may also be that the temperature is too high, and the water in the leaves evaporates too quickly in a high temperature environment, which can also easily lead to yellowing of the leaves.

Strengthen ventilation when the temperature is high, and spray water frequently to cool down. It may also be infected with diseases, common leaf spot, cut off the diseased leaves in time after being found, and spray drugs. In addition, improper watering is also prone to this situation, and it is necessary to provide water reasonably.

Although the osmanthus loves the light, it is afraid of the scorching summer sun. If you don't block the strong light in time in summer, long-term exposure to the sun will cause sunburn to the leaves, and the leaves will turn yellow and the tips of the leaves will dry up. To shade as soon as possible, the ground planting can be set up with a shade net, and the potted plants can be moved to a semi-shaded and ventilated place.

Osmanthus prefers a warm environment, with temperatures between 18 and 28 degrees Celsius at its best. It has limited resistance to high temperatures. If it is exposed to high temperature for a long time, the water of the leaves will evaporate too quickly, and the leaves will easily turn yellow or even dry out.

In this case, ventilation should be strengthened, and water should be sprayed frequently to help it cool down.

The original slag of the yellowing of the leaves of the osmanthus tree is as follows:

1. Watering problems, the soil of osmanthus should have good air permeability, and be afraid of waterlogging. It is best not to dry and not water, and water thoroughly every time. Afraid of waterlogging and waterlogging, if it is harmed by waterlogging, the root system will be black and rotten, the leaf tip will be scorched and withered, and then the whole leaf will wither and fall off, which will lead to the death of the whole plant;

2. For light problems, it is appropriate to arrange the degree and duration of seeing light of osmanthus;

3. For the problem of humidity, in the environment of rising temperature or dryness, the method of shading and spraying is used as much as possible to improve the environmental humidity. Generally speaking, it is the tip of the old leaves, as long as the humidity is increased by more than 60%, it can be improved.

4. Temperature problem, the most suitable growth temperature is 15 to 28 degrees Celsius, low or high temperature may cause problems;

5. For ventilation problems, it is necessary to increase ventilation in a timely manner. It is suitable for planting in a ventilated and light-transmitting place, prefers a clean and ventilated environment, and is not resistant to smoke and dust;

6. For fertilization problems, potassium fertilizer and humus fertilizer should be increased to improve the width of its beam or its own disease resistance energy;

7. Bacterial problem, brown spot disease, in the early stage of the disease, there are small yellow spots on the leaves, which gradually expand into nearly round spots, brown spot disease generally occurs from April to October, and the old leaves are more susceptible than the young leaves.

The reason for the yellowing of osmanthus leaves is temperature, light, water and fertilizer.

1. Temperature reasons

The most suitable temperature for the growth of the osmanthus tree is 15 to 25 degrees, and if the temperature exceeds 30 degrees, then its leaves may turn yellow. At this time, it is best to put it in a cooler and more ventilated place to cut off those dry and yellow leaves. In addition, in winter, it is necessary to do proper warming.

2. Lighting reasons

Although the osmanthus tree prefers sunlight, but the sun is too strong, for example, in the summer it is best to put it in a cooler place, or do a good job of shading, otherwise its leaves will turn yellow if the sun is exposed for too long.

3. Water and fertilizer reasons

When watering the osmanthus tree, you must pay attention to the appropriate amount, whether it is too much or too little, it will make its leaves yellow. Generally, it is watered after the potting soil is dry, and in addition to normal watering in summer, you can also use a watering can to spray some water on its leaves to keep it moist.

In terms of fertilizer, it is about once a month to use fertilizer, and you can use diluted organic fertilizer, which is more natural and easy to absorb. In addition, add some nitrogen, if the nitrogen is deficient, its leaves will turn yellow. Also pay attention to iron, which is also very important for the growth of osmanthus trees, although the amount does not need to be too much, but the lack of leaves will turn yellow.
