Can be placed in the bathroom, windowsill and other narrow space, its slender, beautiful branches and leaves can effectively absorb the formaldehyde released by curtains, and fully purify the air.

Culture method of Phnom Penh Cymbidium

Phnom Penh is a kind of Cymbidium, the planting method is the same as other Cymbidium, generally speaking, Phnom Penh has strong adaptability, luxuriant growth and easy cultivation.

1. Temperature. Cultivate indoors in winter, the temperature should not be lower than 5 degrees.

2. Light. Phnom Penh orchids are extremely sensitive to light. Shading should be carried out in summer and autumn, not in direct sunlight. 50% of the sun can be shaded in spring, or cultured in half-shade, and more light can be seen in autumn. Through observation, it can be found that the light is insufficient, the leaf color is light and sometimes even yellowish green; the light is too strong, and the leaves are yellow.

3. Watering. Appropriate watering during the formation period to keep the basin soil moist. Watering should be controlled in winter. At ordinary times, we should pay attention to the cleaning of the leaf surface and often spray water to the leaf surface.

4. Fertilization. Thin fertilizer is applied every half a month or so in the growing season. Nitrogen fertilizer should be controlled for mosaic varieties.

5. Placement. Hanging orchid can be hung, will have a different flavor, the height is suitable for human eyes or slightly higher, too high is inconvenient to water. When applying fertilizer, it should be removed from the hanging basket, and the leaves should be sprayed and washed carefully after fertilization.

Daily maintenance of Phnom Penh hanging orchids

1. Phnom Penh hanging orchids prefer a semi-overcast environment. If the sun is direct and the air is dry, it is most likely to cause leaf tip scorch. Therefore, the hanging orchid must be placed in a cool and ventilated place, especially to pay attention to often spraying water to the leaf surface to increase environmental humidity.

2. Phnom Penh orchids like to be wet, but if too much watering or poor drainage of basin soil will lead to withered leaves and bananas due to rotten roots. Improper watering and fertilization will also cause the leaves to dry up.

3. Phnom Penh hanging orchids like fertilizer. If there is not enough fertilizer and water, the color of the leaves will become lighter and the leaf tips will be scorched. But do not apply too much fertilizer.

4. We must pay attention to frost injury in winter. Freezing damage occurs when the ambient temperature is below 4 degrees Celsius.

Phnom Penh hanging orchid is a kind of hanging orchid, the planting method is the same as other hanging orchids. Cymbidium, Liliaceae, perennial evergreen herbs. The leaves are broad linear, light green, born on short stems and have large cylindrical fleshy roots. Racemes 30-60 cm long, curved and drooping, with white florets; often produce clusters of rooted plantlets formed by plant buds on flower stems, which is very interesting. It grows fast and is easy to cultivate. It can be cultivated and appreciated all the year round in a brighter room. It is one of the most suitable kinds to be suspended or placed on the top of the cupboard or flower rack. The common cultivated varieties are as follows: the leaves of Phnom Penh are golden, the center of the leaves are yellow longitudinal stripes, the edges of the leaves are white, and the center of the leaves are white longitudinal stripes. Temperature: like warm environment, strong adaptability; the lowest overwintering temperature is about 10 ℃. Light: like bright light, avoid direct sunlight in summer, shading about 50%, no shading in winter. Moisture: there is sufficient water in the perennial basin soil, but it has a certain ability to resist drought; avoid stagnant water in the basin. Air humidity: water is often sprayed around plants and leaves during dry seasons and high temperatures in summer. Change the basin: you can change the basin in spring as needed. Propagation: Cymbidium can be propagated by cutting, ramet, sowing and other methods. Cutting and ramet propagation can be carried out at any time from spring to autumn. Cymbidium has strong adaptability and high survival rate, so it is generally easy to reproduce. When cutting, as long as the stolon with new buds is inserted into the soil in 10 cm, it can take root in about a week, transplant in a pot in about 20 days, and keep it in the shade after pouring water. When ramets, the plant of Cymbidium can be lifted out of the pot, the old soil and rotten roots can be removed, and the old root can be cut open, so that there are three stems on the split plant, and then transplanted and cultured respectively. The clustered stems and leaves on the stolon of Cymbidium can also be cut (in fact, it is a new plant larva, with leaves on the top and air roots on the bottom), and can be planted directly in the flowerpot. The seed propagation of Cymbidium can be carried out in March every year. Because its seed grain is not big, after sowing the seed, the covering soil above should not be thick, generally 0.5 cm. Under the condition of 15 ℃, the seeds can germinate in about 2 weeks, and then transplant and culture after the seedlings take shape. This kind of plant with gray leaves likes to live in a constant temperature. The hanging orchid that is placed in the narrow space such as bathroom, windowsill or shelf is very eye-catching, its slender and graceful branches and leaves can effectively absorb formaldehyde released by curtains and even tampon paper, and fully purify the air. The hanging orchid naturally drooping branches and leaves are very beautiful, when the branches are luxuriant, it will occasionally turn slightly. And it's not complicated to take care of it.

Although the vitality of all kinds of hanging orchids is very tenacious, they will still encounter all kinds of problems in the cultivation of hanging orchids, such as watering, lighting, disease prevention and so on. If the hanging orchid is handled properly, it will grow healthy and luxuriant, and if it is not handled or mishandled, it will inevitably have a negative impact on the cultivation of the hanging orchid. So how to keep the orchid? The editor has more than half a year's experience in hanging orchid culture, coupled with the collection and integration of knowledge points from all parties to the culture of hanging orchid, especially to provide owners with the knowledge of hanging orchid culture methods, types, matters needing attention, and the role of hanging orchid culture, in the hope that it can help and support the majority of owners. First, the living habits of hanging orchid, commonly known as hanging basin grass, originated in Africa, is now cultivated all over the world, and Europeans call it spider grass or aircraft grass. The most important feature of Cymbidium is that the mature plants will grow new stems from time to time, and the new stems will grow into small plants. it likes the warm, humid and semi-shady growth environment, and is suitable for long-term indoor cultivation. The flowers and colors of hanging orchids are mainly white, with several flowers in a cluster, which looks clear and pleasant and has high ornamental value.

There are many kinds of hanging orchids, such as hanging orchids, purple orchids, flower orchids, gold leaf orchids, silver-edged hanging orchids and so on. Among them, the stem of the orchid is indistinguishable from the leaf, the leaf is drooping, the leaf is dark green, it blossoms in June and July every year, and the flowers are yellowish and white; the purple orchid is also called Cymbidium, the main vein of the leaf is purple, the branch is nodular, each node leaves, the leaf is thick and glossy, all drooping, blooming from June to October every year, and the flower color is pink. Flower orchid branches into a vine, branches and leaves drooping, the leaf is like a peach-shaped, the edge of the leaf has a golden pattern, and through the center of the vein, the back of the leaf is purple and gives off light; Phnom Penh has yellow lines around the leaves on the green leaves, which look especially good-looking; on the green leaves of the silver-edged Cymbidium, it is more bright and distinctive. In addition, there are golden orchids, silver orchids, broad-leaf orchids, middle spot orchids and so on. Third, the cultivation method of hanging orchid actually does not take too much thought, in the daily maintenance, the main thing is to water regularly to prevent it from being accidentally hurt, but the difficulty lies in persisting in paying attention to it and not forgetting to ignore it for a long time. Here, the Tuba rabbit editor mainly from the hanging orchid breeding process, need to pay attention to or there may be problems in 9 aspects to decompose the breeding method of hanging orchid. 1. Suitable lighting: the hanging orchid likes the semi-shady environment, and the hanging orchid is very sensitive to the light. if the summer and autumn sunlight is direct, the leaves will wither and yellow, or even the whole plant will die, so it should be kept in a cool and ventilated place, and pay attention to maintaining the humidity of the environment. At most, you can only see some oblique light sooner or later. In winter, because the sun is not strong, we can let the orchid accept some direct sunlight properly. 2. Culture temperature: Cymbidium prefers warm and humid climate and is not resistant to severe cold and heat. The optimum growth temperature of Cymbidium is 15 ℃ 25 degrees Celsius, and the room temperature in winter should not be lower than 5 degrees Celsius. Avoid strong light in high temperature season, need to keep shade sparse, low temperature and cool time should see more sunlight, in order to keep the leaf color bright. In Guangdong Province, China, the temperature in spring, summer and autumn is suitable for the growth of Cymbidium, but attention should be paid to cold prevention and heat preservation when the temperature in winter is lower than 7 degrees Celsius.

The hanging orchid blossoms beautifully. 3. Watering: the hanging orchid likes water, because its fleshy root has developed water storage tissue and strong drought resistance, but it needs more water during the peak growth period from March to September, so it should be watered and sprayed frequently to increase humidity and keep the basin soil completely moist. During the dormant period in winter, the basin soil can be watered after it is dry at a depth of about one centimeter. It should be noted that if the soil is too dry, it will cause the leaves to fade temporarily, although the primary color will be restored after rewatering, but the leaf tip may turn brown permanently. Water should also be sprayed on the branches and leaves around noon and in the evening. 4. Fertilization: Cymbidium is a more fertilizer-tolerant plant. If there is not enough fertilizer and water, it is easy for the scorched head to age, and the leaves turn yellow and lose its ornamental value. For those who have begun to grow small plants, you can apply nitrogen-based topdressing every half a month. If the orchid grows well, it can be done without fertilization. 5. Soil: the cultivation of Cymbidium is suitable for easy and fertile sandy loam, which requires that the soil contains humus and strong permeability. Potted plants can use rotten leaf soil or peat soil, garden soil and river sand mixed with a small amount of base fertilizer as the substrate. After changing the basin, we should pay attention to the re-preparation of new soil. 6. Change soil and change basin: Cymbidium culture generally changes the basin once in 2-3 years, but in specific maintenance, in order to seek luxuriant stems and leaves, soil and basin can be changed in March every year. 7. Pest control: Cymbidium culture is generally not easy to occur diseases and insect pests. The occurrence of the disease is generally caused by stagnant water in the basin soil and poor ventilation, so it should be prevented and treated in time. 8. Pruning: in the aspect of pruning, the yellow leaves should be cut off at any time at ordinary times, and the basin can be turned once every March to cut off the old root, rotten root and excess fibrous root. The old leaves of Cymbidium can be cut off in the first and middle of May, which will promote the germination of more new leaves and small Cymbidium.

Click to view Phnom Penh hanging orchid culture method 9, hydroponic culture: hanging orchid culture can also be hydroponic, to carry out hydroponic culture, you can first pot hanging orchid out of the pot, wash the soil with water, cut off the old leaves, old roots, placed in hydroponic utensils, and then pour clean water. Be careful not to have too much water, just to the root and stem. In order to grow vigorously, you can drop a few drops of nutrient solution into the water. Wide-mouth glass bottles, glasses and other containers can be used for utensils. The water in the container can be changed every few days, or some water can be added. Fourth, how to cause the leaves of Cymbidium to turn yellow? the reasons and solutions are as follows: 1. If there is too much fertilization, which exceeds the requirement of the plant, you should stop fertilizing, irrigate more water, or turn over the pot to clean the root and replace the new soil. 2. The soil has not been turned over for a long time, resulting in the depletion of all kinds of nutrients in the basin soil and the lack of nutrients in the plant, so it should be replaced with fertile loam in time. 3. Due to the lack of light and the decrease of chlorophyll, the work of seeing light should be strengthened. 4. it is the poor air permeability and water permeability of the basin soil, which makes it difficult for the root system to breathe, so the soil should be loosened in time. 5. it has not been watered for a long time, and the root of the orchid has lost water, so it should be watered once to keep the basin soil warm and moist. Fifth, the role of hanging orchids has a very strong function of absorbing toxic gases, if the general room raised 1-2 pots of hanging orchids, the poisonous gases in the air can be absorbed. According to scientific analysis, the orchid can absorb 95% of the carbon monoxide and 85% of the formaldehyde in the air. Therefore, the hanging orchid is not only an excellent hanging leaf plant in the room, but also a good indoor air purification flower, so it has the laudatory name of "green purifier". VI. Propagation of Cymbidium

Beautiful hanging orchids can be propagated by ramets, and can be carried out in other seasons except that the winter temperature is too low to be suitable for ramet. When potted for 2 to 3 years, the dense potted seedlings can be removed from the old culture soil and divided into two to several clumps, which can be potted into new plants. In addition, Cymbidium can also be propagated by the small plants on the walking stem. During the growing season, the small plants on the stems can be cut and planted in the culture soil or water, and then transplanted to the basin after the small plants grow roots to become a new bonsai of Cymbidium. Seventh, the flower language of the hanging orchid is "helpless and hopeful". This has something to do with its growth habits, usually do not need how to manage, will not give people a big surprise, but it is helpless to always pay attention to, and always tenaciously grow very well, which can always bring hope to people. There is also a legend about the flower talk of Diao Lan. It is said that once upon a time there was an examiner who was jealous of talented people. In order to make his godson go to high school, he tried to hold down a talented man named Lin Dexiang. However, when correcting Lin Dexiang's paper, the emperor happened to take a private visit, and the examiner hurriedly hid the paper in the orchid on his desk, but he did not know that the emperor inadvertently learned the truth while watching the brilliant blooming orchids, so he dismissed the examiner from his post. Soon after, the examiner died because of Yu Huaihuan, and the stems and leaves of the potted orchids did not straighten up again, slowly evolving into today's hanging orchids. The above is the whole content of this article, owners in the breeding process of hanging orchids, if they can breed in accordance with the above requirements, do not want to raise your hanging orchids well, on the one hand, your method is in place, on the other hand, because the vitality of hanging orchids is really tenacious, I hope that owners can breed luxuriant and beautiful hanging orchids with the support of the service of Tuba rabbits. What if the leaves of the orchid turn yellow? How to raise orchid leaves after yellowing? What if the leaves of the orchid turn yellow? How to raise orchid leaves after yellowing? Cymbidium is a perennial evergreen perennial herbaceous flower with various forms, strong shade tolerance and easy management. It is often used to hang potted plants for indoor decoration or garden setting. Hanging orchids like the humid environment, always keep the basin soil moist, adequate watering in summer, and spray water on the branches and leaves around noon and in the evening to prevent the leaves from drying up. There is often much dust in the room, such as more dust on the orchid, which not only affects its growth, but also damages the freshness and freshness of the branches and leaves, so we should often spray and wash the branches and leaves to keep them bright and beautiful. However, what should be done if the leaves turn yellow in the process of growth?

Step / method fertilizing too much, exceeding the requirement of the plant. At the beginning, the leaves were shiny and uneven, the roots rotted and the leaves were yellow. Should stop fertilizing, irrigate more water, or turn the pot to clean the root and replace the new soil.

I haven't turned the basin and changed the soil for a long time. The various nutrient elements in the basin soil have been exhausted, the three elements of nitrogen, phosphorus and potassium have not been replenished in time, the plant is lack of nutrients, and the leaves are yellow and thin. Fertile loam and fertile water should be replaced in time.

Although the orchid is a semi-negative flower, at least four hours of astigmatism should be seen every day, otherwise the chlorophyll will decrease and the leaves will turn yellow.

The permeability and water permeability of basin soil are poor. The long-term accumulation of water in the basin soil makes it difficult for the root system to breathe, which leads to the yellowing of the leaves. The soil should be loosened and moisture should be controlled in time. Fifth, it is impervious to water for a long time. The roots of Cymbidium lose water, and the lower old leaves turn yellow. It should be watered thoroughly to keep the basin soil warm and moist.

Matters needing attention to grasp the four main points of like shade, often spraying water, fertilizing frequently, and often changing pots, it is believed that it is easy to breed beautiful hanging orchids.

How to raise the orchid well

Phnom Penh Cymbidium culture method: temperature: Phnom Penh Cymbidium likes a warm environment, strong adaptability; the lowest overwintering temperature is about 10 ℃. Light: like bright light, avoid direct sunlight in summer, shading about 50%, no shading in winter. Moisture: there is sufficient water in the perennial basin soil, but it has a certain ability to resist drought; avoid stagnant water in the basin. Air humidity: water is often sprayed around the plant and leaves of Phnom Penh during the dry season and high temperature in summer. Change the basin: you can change the basin in spring as needed. Propagation: Phnom Penh Cymbidium can be propagated by cutting, ramet, sowing and other methods. Cutting and ramet propagation can be carried out at any time from spring to autumn. Cymbidium has strong adaptability and high survival rate, so it is generally easy to reproduce. When cutting, as long as take the stolon with new buds 5-10 cm into the soil, about a week can take root, about 20 days can be transplanted on the pot, poured water to keep in the shade. When ramets, the plant of Cymbidium can be lifted out of the pot, the old soil and rotten roots can be removed, and the old root can be cut open, so that there are three stems on the split plant, and then transplanted and cultured respectively. The clustered stems and leaves on the stolon of Cymbidium can also be cut (in fact, it is a new plant larva, with leaves on the top and air roots on the bottom), and can be planted directly in the flowerpot. The seed propagation of Cymbidium can be carried out in March every year. Because its seed grain is not big, after sowing the seed, the covering soil above should not be thick, generally 0.5 cm. Under the condition of 15 ℃, the seeds can germinate in about 2 weeks, and then transplant and culture after the seedlings take shape. Cymbidium is a perennial evergreen perennial herbaceous flower with various forms, strong shade tolerance and easy management. It is often used to hang potted plants for indoor decoration or garden setting. Its management should grasp the following points: first, temperature control. Cymbidium prefers warm and humid climate and is not resistant to cold. It grows fastest at 20 / 24 ℃ and stops growing at more than 30 ℃. The leaves are easy to turn yellow and dry tip. Second, light adjustment. Outdoor cultivation in summer should pay attention to shade, so as not to make the light too strong, otherwise sunburn can easily occur. Third, the regulation of water and fertilizer. Spring and autumn growth season, watering should be adequate, basin soil should always keep moist, and often spray branches and leaves with water close to room temperature, to prevent dry tip, but not stagnant water. Fourth, trim and change the basin. As the plant grows, the old leaves at the base should be cut frequently in order to maintain a good plant shape. Fifth, pest control. The dense plant clusters of Cymbidium are poorly ventilated and vulnerable to scale insects, so prevention should be given priority to. Phnom Penh has strong adaptability and high survival rate, so it is generally easy to reproduce. Phnom Penh can be propagated by cutting, ramet, sowing and other methods. Cutting and branch propagation, Phnom Penh can be maintained at any time from spring to autumn. Phnom Penh always feels that the leaves are soft, the reason may be: 1 the basin soil is too dry, the basin soil is too dry, it is not easy to water, it will be dripping. If the inspection place is really too dry, carry out a sitting basin method to replenish water so that the water can fully soak the basin soil. 2 should pay great attention to spraying leaf water, basin soil wet can not replace the air environment wet, the current climate spray more than twice a day is not much. At this temperature, do not look directly at the sun, but also guard against strong winds. If it is suspended, don't get too close to the wall and don't let other objects touch it. The daily maintenance of the second hanging orchid 1 the hanging orchid likes the semi-shady environment, if the sunlight is direct, coupled with the dry air, it is most likely to cause leaf tip scorch. Therefore, the hanging orchid must be placed in a cool and ventilated place, especially to pay attention to often spraying water to the leaf surface to increase environmental humidity. 2 although the orchid likes to be wet, too much watering or poor drainage of the basin soil will lead to withered leaves and bananas due to rotten roots. Improper watering and fertilization will also cause the leaves to dry up. 3 hanging orchid likes fertilizer, if there is not enough fertilizer and water, the leaf color will become lighter and the leaf tip will be scorched. But do not apply too much fertilizer. (4) attention must be paid to frost injury in winter. Freezing damage occurs when the ambient temperature is below 4 degrees Celsius. Generally speaking, Cymbidium has strong adaptability, luxuriant growth and easy cultivation. 1 the temperature is cultivated indoors in winter, the temperature should not be lower than 5 degrees; 2 the light hanging orchid is very sensitive to light. Shading should be carried out in summer and autumn, not in direct sunlight. 50% of the sun can be shaded in spring, or cultured in half-shade, and more light can be seen in autumn. Through observation, it can be found that the light is insufficient, the leaf color is light and sometimes even yellowish green; the light is too strong, and the leaves are yellow. (3) watering more during the watering period to keep the basin soil moist. Watering should be controlled in winter. At ordinary times, we should pay attention to the cleaning of the leaf surface and often spray water to the leaf surface. (4) rarefied fertilizer is applied every half month or so in the growing season. Nitrogen fertilizer should be controlled for mosaic varieties. 5 put hanging orchid feasible, will have a different flavor, the height is suitable for human eyes or slightly higher, too high is inconvenient to water. When applying fertilizer, it should be removed from the hanging basket, and the leaves should be sprayed and washed carefully after fertilization. Phnom Penh Cymbidium how to maintain Liliaceae, perennial evergreen herbs. The leaves are broad linear, light green, born on short stems and have large cylindrical fleshy roots. Racemes 30-60 cm long, curved and drooping, with white florets; often produce clusters of rooted plantlets formed by plant buds on flower stems, which is very interesting. It grows fast and is easy to cultivate. It can be cultivated and appreciated all the year round in a brighter room. It is one of the most suitable kinds to be suspended or placed on the top of the cupboard or flower rack. The common cultivated varieties are as follows: the leaves of Phnom Penh are golden, the center of the leaves are yellow longitudinal stripes, the edges of the leaves are white, and the center of the leaves are white longitudinal stripes. Temperature: like warm environment, strong adaptability; the lowest overwintering temperature is about 10 ℃. Light: like bright light, avoid direct sunlight in summer, shading about 50%, no shading in winter. Moisture: there is sufficient water in the perennial basin soil, but it has a certain ability to resist drought; avoid stagnant water in the basin. Air humidity: water is often sprayed around plants and leaves during dry seasons and high temperatures in summer. Change the basin: you can change the basin in spring as needed. Propagation: Cymbidium can be propagated by cutting, ramet, sowing and other methods. Cutting and ramet propagation can be carried out at any time from spring to autumn.
