For Cymbidium, many flower friends should be no stranger, it is a very precious variety of orchids, with large flowers and bright colors, often potted indoors. However, in the process of cultivating Cymbidium, many people encounter yellowing leaves. So, what if the leaves of Cymbidium turn yellow? In this regard, the editor summed up 6 reasons, let's go and have a look!

First, the leaves of Cymbidium turn yellow, look for the cause.

In daily life, there are many people who raise Cymbidium, but when beginners raise it, they often do not follow the cultivation method of Cymbidium, so they often encounter the situation that the leaves turn yellow, which seriously affects the ornamental ability. what about the yellow leaves of Cymbidium? In this regard, the editor summed up the six reasons for the yellowing of Cymbidium leaves, let's go and have a look!

Second, the causes and solutions of the yellowing of Cymbidium leaves.

1. Environmental mutation

In fact, there are many reasons for the yellowing of Cymbidium leaves, but environmental factors are the first thing to consider. The reason for this is that many flower friends buy Cymbidium from the Internet, which can easily lead to a large geographical span, Cymbidium can not adapt for a while, resulting in leaf yellow symptoms.

Solution: at this time, you can communicate with the shop owner to understand the growth environment before the purchase of Cymbidium, and then we can change it to the same environment at home. Then slowly change until fully adapted to the current environment, after a period of time, Cymbidium will return to health.

2. Too much watering

Cymbidium likes the moist environment, so we should water it frequently. But Cymbidium has fleshy roots and can store water, so it is more drought-tolerant. Once too much watering, it is easy to lead to stagnant water at the bottom of the basin, affecting the air permeability of the root system, causing rotten roots, and the end result is that the leaves gradually turn yellow.

Solution: reduce watering, move the flowerpot to a ventilated sunny place, and let the water evaporate quickly. After the Cymbidium is restored, the watering should be dry and wet, and the interval of watering should be flexibly controlled according to the room temperature. There is a detailed introduction on how to water Cymbidium, so I won't say much here.

3. Excessive fertilization

Cymbidium likes fertilizer, but once it is fertilized too much, it can cause fertilizer damage and cause the leaves to turn yellow. in addition, when potted Cymbidium is bought in the florist, some businesses add some flower soil to the pot, and when we buy it back, the organic matter in some flower soil will ferment and release heat energy, burn the roots, and rot the roots, causing the leaves of Cymbidium to turn yellow and even die.

Solution: when fertilizing too much, properly watering and diluting; if it is a newly bought potted plant, it is recommended to check the flower pot soil carefully to ensure that the flowers grow healthily.

4. The temperature is too low

Cymbidium likes a warm environment, although it is more hardy, but the temperature is too low for it to bear. Especially in the north, it needs to be maintained indoors in winter. if it is attacked by air-conditioning, it will also cause the leaves to turn yellow.

Solution: if the leaves of Cymbidium are yellowed by air conditioning, the situation is generally not serious. You only need to cut off the yellowed leaves, slowly recuperate and recover after a period of time.

5. The humidity is too low

Cymbidium has higher requirements for air humidity. If the indoor air humidity is low and the temperature is on the high side, the yellow leaf scorched edge phenomenon is easy to occur. In addition, the leaves of Cymbidium are easily yellowed when they are blown by cold or hot air near the air conditioner.

Solution: spray water on the leaves every day to increase air humidity; if the leaves are yellow caused by air conditioning, just remove the plant and cut off the yellow leaves.

6. Lack of light

In addition to the above, the reason for the yellowing of Cymbidium leaves may also be that the light is too weak. It is understood that Cymbidium likes light, but avoids bright light, once it is placed in the shade of the room for a long time, it will cause some diseases of its poor growth, which will lead to the emergence of leaf yellow.

Solution: when raising Cymbidium indoors, it is best to put it on the balcony or a place with plenty of light, and we should also pay attention to whether the flowers adapt to the small environment of this location.

Generally speaking, Cymbidium is easy to raise, but because many flower friends are novice, it is inevitable to have the symptom of leaf yellow. However, after reading the full text, I believe you have a bottom in your mind. If there is a Ye Huang problem, you can follow the above method.

What about the yellowing leaves of Cymbidium grandiflora? the culture method of Cymbidium

Cymbidium is very popular because of its wide variety, large flowers, bright colors, delicate fragrance and elegance. However, many people do not know much about the culture of Cymbidium, so there are some problems in breeding. Next, I will tell you what to do when the leaves of Cymbidium turn yellow, as well as the breeding methods of Cymbidium.

What if the leaves of Cymbidium turn yellow?

1. The light is too poor

Cymbidium likes light but is afraid of strong light, generally, scattered light is better, too weak light will also cause its poor growth and some diseases, such as yellow leaves. In general, indoor appreciation is based on the indoor location to determine the location of flowers. When installing Cymbidium, we should pay attention to whether the location is suitable for the growth of Cymbidium, which will not have direct light, but also can provide enough astigmatism.

2. Improper watering

Although Cymbidium likes to be wet, because of its strong moisturizing ability of pot medium and fleshy roots, it is suggested that it should not be watered too often, otherwise too much watering will cause root rot and leaves yellowing. Cymbidium can be watered with clear water close to room temperature, and the interval of watering can be controlled according to room temperature. Water slowly and slowly, do not pour.

3. Excessive fertilization

Huilan flowering is not suitable for watering, otherwise the flowering period will be shortened, improper use of fertilizer will also appear fertilizer damage, resulting in yellowing leaves, suitable for watering fertilizer after flowering.

4. The temperature is too low

Although Cymbidium is more hardy, it is unbearable at lower temperatures. It will cause damage to leaves or flowers, and the leaves will slowly turn yellow. There are victims of this type, can only cut off the yellowed leaves of Cymbidium, slowly recuperate, but generally not fatal.

5. Environmental discomfort

Cymbidium is a kind of flower that likes high air humidity. If the indoor air humidity is low and the temperature is on the high side, the yellow leaf scorched edge phenomenon is easy to occur. You can spray water several times a day to increase the humidity of the small environment. In addition, there may be air conditioning blowing directly or close to the heating and other prone to dry small environment, but also extremely prone to coke edge yellow leaves. When this phenomenon occurs, you only need to adjust it. But the leaves are yellow and can only be cut off.

6. Improper transplantation

Cymbidium sold in the market will be replaced with more beautiful and noble porcelain pots, but in the process of changing pots, because the flowerpots are larger, some businessmen add some flower soil to the pots, but some flower soils are not rotten. To be changed to the pot after the sale to the organic fermentation to release heat, the damage to the flowers, the root system is burned, the root rot phenomenon, resulting in yellow leaves or death of the plant. Therefore, when choosing Cymbidium, we should carefully examine the soil of the flower pot to ensure that the flowers grow healthily.

Culture methods of Cymbidium

1. Soil: Cymbidium requires loose, ventilated and well-drained cultivation substrate, which can be planted with rotten leaf soil or mixed cultivation with moss, charcoal, fern root, charcoal, bark, broken bricks and so on. It is not suitable to use ordinary culture soil and culture soil for planting Chinese orchids. Poorly ventilated and drained soil can lead to root rot.

2. Watering: Cymbidium likes higher air humidity. In spring, summer and autumn, while giving sufficient water to the roots, the leaves should be sprayed frequently. However, during the short dormancy period after flowering in early spring, Cymbidium must be watered less and more watering only when the new buds grow larger and new roots.

3. Sunshine: the growth of Cymbidium needs sufficient scattered light, shading net should be used to shade about 50% in summer and autumn, and open shading net to accept direct light on cloudy days or when the sun is soft in winter and spring. However, during the flowering period, the orchid plant should be placed in a place with weak light so that it can blossom brightly.

4. Temperature: warm in winter and cool in summer, and the suitable temperature for growth is 10 ℃ to 25 ℃. The suitable temperature at night is about 10 ℃, especially when the temperature is above 5 ℃ during flowering, and the flowering period can be prolonged by more than 3 months when the temperature is below 15 ℃.

5. Fertilization: during the growth period, thin fertilizer should be applied frequently, and thin chemical fertilizer or compound fertilizer can be applied. If more bone meal and mature bean cake fertilizer are applied, the flowers will be larger and more. Liquid fertilizer should be diluted at 1 ∶ 1000 and applied once every 10 days. Sufficient fertilizer should be applied before flowering, and no fertilizer should be applied during flowering and midsummer.

6. Insect pests: Cymbidium is vulnerable to diseases and insect pests if the cultivation environment is bad. Common diseases include Fusarium disease, black rot, soft rot, anthracnose, gray mold, white silk disease, etc., so it is necessary to spray fungicide every half a month to prevent the occurrence of diseases, and special attention should be paid to the cleaning of environmental sanitation, water sources, plant materials and utensils.

7. Pruning: the pseudobulm of Cymbidium generally contains more than 4 leaf buds. In order not to disperse nutrition, the new buds and their growing points must be removed thoroughly. This operation should start from the end of the flowering period, pick buds once a month and stop before the new flowering period, so as to concentrate nutrition, strengthen the mother corm and make the flowers bloom bigger and more.

The above are the reasons and solutions for the yellowing of the leaves of Cymbidium, as well as the breeding methods of Cymbidium. I hope it can help you. Please pay attention to more household knowledge.

What to do if the leaves of Cymbidium turn yellow? the culture method of Cymbidium

Although Cymbidium likes to be moist, because of its strong moisturizing ability of potted plants, its root system is fleshy, more resistant to mild cold and more resistant to cold. Therefore, it is recommended not to water too much, watering only needs clear water close to room temperature, there is no need to irrigate fertilizer during flowering, and fertilizer will be applied after flowering, otherwise the flowering period will be shortened and improper use of fertilizer will lead to fertilizer damage. Can be controlled according to the room temperature watering interval days, watering time to slowly carry out slow watering, not too impatient.

2. There are perishable organic matter in pot substrate.

Now the big flower cymbidium sold on the market will be replaced with more beautiful and noble porcelain pots, but because in the process of changing pots, the flowerpots are relatively large, some businesses will add some flower soil to the flowerpots, but not all flower soils are mature, when organic fermentation releases heat energy when organic matter is sold in the pot, and causes certain damage to flowers. The root system of Cymbidium was burned, and the rotting root gradually appeared, which would cause the plant to turn yellow or wither and die. It is suggested that it is best to carefully observe the potted soil of flowers, so as to ensure the healthy growth of flowers.
