What s wrong with the rotten roots of the yellow leaves of the orchid. Orchid leaves turn yellow and

Too much watering, orchids like shade, like dryness, can't water too much. Hope.

One of the reasons for the rotten roots of orchids: environmental discomfort.

Lack of light: orchids due to different varieties, the required sunlight conditions, light time is different, but fundamentally adhere to more than 4 hours, the lack of light or dim light, the photosynthesis of orchid plants is weak, and the potting soil is not simply dry after sprinkling, and the water will stay in the pot for a long time, which affects the growth of the root system and constitutes the situation of rotten roots.

Not ventilated may be too ventilated: without ventilation, the Chinese environment for raising flowers is hot, the sprinkling is not simple to dry, and the transpiration of the plant is also weakened; If there is too much ventilation, the water in the pot will be dried quickly, and if the water is not replenished in time, the water stored in the roots will gradually run out, and the roots will gradually dry out.

Humidity is not good: Orchids like a humid environment, and the growth of roots also needs to fluctuate humidity and temperature, too dry or too hot will cause orchids to rot their roots.

Therefore, improve the growth environment of orchids, ensure proper humidity, temperature, and ventilation, assuming that orchids continue to rot roots and grow poorly, most of the reasons are still because the environment is too monotonous, especially in winter, and the humidity is lacking, so we should pay attention to the control of ventilation, light and humidity.

The second reason for the rotten roots of orchids:

The time and method of sprinkling water are not the same as the time and method of sprinkling orchids should change with the dry and wet conditions of the potting soil and the temperature of the four seasons. Therefore, it is best to sprinkle water in the morning in summer, and by the next day the water will drip and the potting soil will not be too wet. Secondly, the sprinkling should observe the growth of the plant, if the growth is not good, the sprinkling method and the amount of sprinkling should be changed in time.

If the temperature is too low (below 10 degrees) or too high (above 30 degrees), do not sprinkle water, which will simply cause the orchid plant to rot due to frostbite or steaming.

The third reason for the rotten roots of orchids: improper fertilization.

Orchids are fleshy roots, and the roots store a small amount of water, and there is no way to absorb high concentrations of fertilizer, especially in the case of root trauma, the roots will suffer from fertilizer damage and constitute rotten roots. Therefore, when fertilizing, thin fertilizer should be applied frequently. In addition, when trying fermented inorganic fertilizer or long-acting fertilizer, do not be too close to the roots to prevent root rot.

The fourth reason for the rotten roots of orchids: sickness.

In this case, we only pay attention to the prevention and control of pests and diseases, and ignore the existence of rotten roots.

1. Watering. Excessive watering leads to water accumulation in the pot, which is a mistake that flower friends are easy to make, once the water in the pot its root system will not be able to have a better breath and absorption of nutrients to provide to the leaves, then the plant will appear leaves yellow. Workaround:

You should choose a flower pot with good ventilation and drainage, so that the potting soil is not dry, and it is okay to water it thoroughly.

2. Air drying.

Dry air causes orchids to lack water and yellowing leaves, due to a long time of not getting more watering or often too busy to remember to water the orchid, which will also cause the orchid to lack water and cause the leaves to turn yellow.

The reasons why orchid leaves turn yellow and break off from the roots are as follows:Reason 1: If it is a plant that has just been bought, then it is likely that there will be some growth problems with the orchid due to transportation.

Reason 2: If you put an orchid in a place where the air is not well circulated, and when you water it, there is a lot of water, it is prone to soft rot, and the main symptoms are from the leaves to the roots to become dry.

Reason 3: Orchids are plants that are more afraid of waterlogging. Orchids are also prone to this problem if they are exposed to excessively humid and waterlogged soil for a long time.

1. Control watering: After the orchid leaves turn yellow, you need to wait for the soil surface to dry before watering to avoid stagnant water in the soil. 2. Apply thin fertilizer:

Orchids are not tolerant of thick fertilizers and need to apply thin liquid fertilizers every other month. 3. Suitable light: move the orchid to the scattered light to avoid it from being directly exposed by strong light, so that the yellow leaves of the orchid turn green.

The solution of orchid yellow leaves.

1. Adjust the watering

The yellow leaves of the orchid may be caused by improper watering, because it likes a moist environment, but is afraid of waterlogging, so if it is watered too much and causes water accumulation, or too little watering to dry the potting soil, it is easy to cause its leaves to turn yellow. At this time, the watering should be adjusted according to the situation, increasing the watering if it is dry, and draining and drying the roots in time if there is stagnant water.

2. Dilute fertilizer

Orchids do not need a lot of fertilizer, and too much fertilizer or heavy fertilizer can burn the rhizome of the orchid and cause its leaves to turn yellow. When this happens, the orchid should be watered the next day to dilute the fertilizer in the soil and drain it from the hole in the bottom of the pot with the excess fertilizer.

3. Adjust the lighting

Orchids have strict requirements for light, and cannot be exposed to strong direct light, nor can they lack light, otherwise the leaves will turn yellow. After the leaves are yellow, you need to adjust the light intensity and light time, early spring and winter can allow it to receive full sunlight, and the rest of the time it is placed in a well-ventilated area to receive scattered light and avoid direct sunlight.

Through our introduction, I believe you have a deeper understanding of how to make orchid yellow leaves.

1. Shade: After the leaves of orchids turn yellow, they need to be moved to a ventilated and ventilated place of scattered light. 2. Fertilization:

Potassium dihydrogen phosphate or nitrogen fertilizer is applied to orchids once a month to turn their yellow leaves green. 3. Watering: Orchids are not tolerant to stagnant water, so they need to wait for the soil surface to dry before watering.

4. Pruning: Cut off the yellow leaves of the orchid, and then spray it with fungicide.

1. Temperature and sunlight

Orchid leaves are yellow, but can grow normally, a large reason is excessive light, orchids are suitable for growth in 10-25 degrees. At this time, just move the orchid to a cool and dark place. Orchids prefer a semi-shady environment, except for early spring and winter, where they can grow in the sun, they should be placed in a cool place with scattered light at other times, avoiding direct sunlight.

2. Fertilizer application

When the orchid leaves turn yellow and the new shoots are smaller, it is a lack of fertilizer and excessive light, so it should be fertilized twice, and nitrogen fertilizer can be diluted with water. Orchid fertilization is best to use the special fertilizer of orchids, too much fertilization shows that the old leaves and branches turn yellow and fall off, the new leaves are thick but uneven and not stretched, especially in the hot season, too much fertilization can easily lead to orchids being burned.

3. Water volume control

The old leaves turn yellow and fall off quickly, which may be due to overwatering, at this time, you should check the drainage of the soil and whether the roots of the plant are rotten, and change the soil or prune the roots in time. If not watered for a long time, the new leaves will look normal in color, but the old leaves will gradually dry up and fall off.

4. Pest and disease poisoning

Orchid pests and diseases are generally relatively few, so we should pay attention to distinguishing them. Melasma on the leaves is caused by heat in the roots. There are irregular macula on the leaves, which are caused by a virus.

There are small yellow spots on the leaves, which are caused by beetles, and corresponding measures should be taken at this time, spraying pesticides or manual control.

5. Environmentally

At this time, the orchid should be transferred to a place with a suitable temperature and soft light, increase ventilation, orchids like moisture, maintain appropriate air humidity, control watering and normal maintenance, and the orchid can slowly return to normal after a period of time.

Orchid yellow leaves may be caused by long-term lack of water, need to replenish water in time, if the planting soil is too compact, it is best to choose loose and breathable soil for planting, check whether the root system is rotten, prune the rotten root system, summer breeding needs to move it into a semi-shaded environment, and at the same time can not be applied thick fertilizer.

1. Moist curing

Orchid is a plant that likes a humid environment, if it is not watered for a long time in the breeding process, resulting in a shortage of water, there will be a phenomenon of yellow leaves, at this time it is necessary to water in time, but there can be no phenomenon of water accumulation, keep the soil moist, in the summer season, you also need to spray clean water, improve the humidity environment.

2. Replace the soil

At this time, it is best to replace the old soil, choose loose and breathable humus or sandy soil for cultivation, check whether the root system is rotten in the process of changing the soil, and prune in time.

3. Reduce light

Orchid is a semi-shaded plant, if it is irradiated with strong light for a long time, there will be yellow leaves, especially in summer, the light is too strong, it is best to move it into a cool and ventilated environment for maintenance, and so the leaves gradually return to normal, move it to the astigmatism place to breed.

4. Proper fertilization

If the orchid is not fertilized properly, the phenomenon of fertilizer damage will also lead to the yellowing of the leaves, do not apply fertilizer that is not rotten or has a relatively high concentration, otherwise it needs to be diluted with a large amount of water, if the soil is replaced, the root system will be cleaned with water and then re-cultivated.

Summary. Your question relates to the disease of orchids. Depending on what you described, the yellowing of the roots of the orchid's leaves may be due to malnutrition or a specific disease.

Please consider checking the roots of the orchid and the soil for any abnormalities such as viruses, fungi or other insect viruses. In addition, you can try to buy some special nutrients for orchids to supplement their nutritional deficiencies to restore their normal growth state.

This is a pot of little prodigy orchids, and the roots of the leaves have recently turned black and broken, what is the cause of this?

Orchids are a high-end and elegant flower that is widely loved for its elegant and fresh bonsai effect and colorful varieties. However, in the process of orchid maintenance, there are often some problems, such as the yellowing of the roots of the orchid leaves, which will have a negative impact on the growth of orchids if they are not treated in time.

First, let's take a look at why the roots of orchid leaves turn yellow and break off at the touch. Usually, this condition is caused by an attack on the roots of orchid leaves by a fungus or insect infestation. The roots of the orchid are the key parts of the whole orchid growth, if the roots are attacked by germs or insect pests, it will cause the orchid to not absorb enough water and nutrients, resulting in the phenomenon that the roots of the orchid leaves are yellow and broken when touched.

In view of the problem of yellowing of the roots of orchid leaves, we need to take effective measures to carry out **. First of all, we should strengthen the management of the growth environment of orchids, ensure that the growth environment is kept moist and ventilated, and avoid too wet, too dry and other conditions that are not conducive to the growth of orchids. Secondly, we need to spray fungicides and insecticides in time to ensure the health of orchid roots.

Finally, we need to provide the orchid with enough nutrients and water so that it can resume growth quickly.

In short, the yellowing of the roots of orchid leaves is a typical orchid growth problem, which requires us to take effective measures to carry out **. Only by maintaining a suitable growth environment, eliminating germs and pests in time, and providing sufficient nutrients and water for orchids, can we make orchids grow healthily and show their unique beauty.

The growth of orchids needs sufficient and clear light, and if it is not exposed to the sun, the water will evaporate slowly, and its roots will not be able to breathe, and the roots will rot. If you overwater an orchid for a long time, water will accumulate in the potting soil, which will cause its roots to rot.

Causes of orchid root rot.

1. Insufficient light:The growth of orchids needs sufficient light, if the light is not enough for a long time, it will affect its photosynthesis, and it will not be exposed to sunlight, the water will evaporate slowly, and its roots will not be able to breathe, and there will be rotten roots.

2. Overwatering:If you don't control the amount of watering well and overwater the orchid for a long time, water will accumulate in the potting soil, which will cause its roots to rot.

3. Excessive fertilization:If too much fertilizer is applied during the growth period of the orchid, its roots will not be able to absorb all the fertilizer, and it will be damaged, resulting in root rot.

Orchid rotten root treatment.

1. First of all, when raising the key attack, we can let the orchid receive no less than 4 hours of light every day, but we should pay attention not to expose to the sun, and we can also properly strengthen ventilation to let the water in the soil evaporate as soon as possible.

2. When we find that the roots are rotten, we should immediately stop or reduce watering the orchid, wait for the potting soil to become dry before watering, and stop watering when the temperature is too low.

3. Of course, if the root has been found to have rotten roots in the maintenance process, we need to appropriately reduce the amount of fertilizer, avoid getting close to the roots of the orchid when applying organic fertilizer, and increase the number of watering if you accidentally fertilize too much, dilute the excess nutrients with water, so that the fertilizer can be discharged faster.

Prevent root rot in orchids.

When planting orchids, you can add ceramite, stones and other particles to humus and peaty soil to increase the permeability and drainage of the soil.
