Goldfish hanging orchid leaves yellow, black, withered how to do

Goldfish hanging orchid is loved by many people with its unique and lovely shape, but many flower friends encounter the problem of goldfish hanging orchid leaf yellow. In fact, the key to this problem lies in the lack of understanding of the habits of goldfish hanging orchid. Below we summarize what can lead to goldfish hanging orchid leaves yellow, black, flower friends can understand one by one.

Goldfish hanging orchid leaves yellow and black reasons 1. Goldfish hanging orchid leaves yellow: light

The light condition is good, give goldfish hanging orchid enough light. Goldfish orchids like to grow in a semi-shady environment, but too good light will affect its growth, mainly showing that the leaves become dim, and have a tendency to turn yellow, and eventually wither and blacken.

2. Goldfish hanging orchid leaf yellow: watering

Often watered for fear of lack of water. Although goldfish hanging orchid likes the environment with high humidity, if there is water in the basin, it may cause the leaves to turn yellow. in this case, the yellowing color of the leaves is the kind of bright yellow, which looks very fresh.

3. Goldfish hanging orchid leaf yellow: temperature

If the ambient temperature is too low or too high, the best growth temperature is 18 ℃-22 ℃. If the temperature lasts more than 30 ℃, the leaves will fall off. High temperature in summer, goldfish orchid growth is very slow or almost stopped growing, at this time should take appropriate shading measures, in order to make its growth exuberant, not defoliation. When the temperature is below 10 ℃ for two consecutive days, the leaves begin to turn yellow and dry until they fall off with the slightest vibration.

4. Goldfish hanging orchid leaf yellow: insect pest

For example, there are small particles of soil at the bottom of the goldfish orchid basin, which may be ants in the soil, because the root fluid of the goldfish orchid is sweet and cool, and it may also be that there are some ants in the soil itself. It is recommended to find a flowerpot to replant, and then remove the whole mother flower with the soil, then rinse the original soil gently in a basin or bucket filled with water, be careful not to hurt the root and beard, and finally choose another flowerpot to reload it. Rescheduling is for insurance, and it is estimated that changing soil and transplanting will solve the problem you raised.

5. Goldfish hanging orchid leaf yellow: caused by discomfort of moving basin

If the pots are moved during the flowering period, the leaf tips may be withered and yellow, and the flowers will decay faster. As long as the yellow is particularly serious off, as usual maintenance, pay attention to shade and keep the leaves moist.

What about goldfish hanging orchid leaf yellow?

1. Environment: it is best in a semi-shaded environment with bright astigmatism, and it is best to feel a little wet.

2. Soil: although goldfish orchid is not strict with the soil, it is best to have a well-drained and fertile soil.

3. Watering: do not spray water on the leaves, especially when the light is good. At ordinary times, the soil can keep the tide properly, there is no need for stagnant water, it does not matter that the basin soil is dry at all.

Culture method of goldfish Cymbidium

Goldfish hanging orchid, also known as goldfish flower, kangaroo orchid, kangaroo flower and so on, is a very lovely and lively plant. Indeed, the goldfish hanging orchid is dense, with many lovely and tender leaves is a very beautiful plant. Goldfish hanging orchid is not only a very good indoor hanging foliage plants, but also has the role of absorbing formaldehyde to purify the air, very practical. So how to raise goldfish orchids.

Culture method of goldfish Cymbidium

1. Goldfish orchid soil should choose loose soil, with a good drainage effect of sandy soil, he is the soil can not contain calcareous, suddenly it is best to be acidic, which is conducive to the growth of goldfish orchid.

two。 Goldfish hanging orchids like warm, moist and semi-shady, not resistant to drought living environment, summer should pay attention to avoid sunlight, winter should pay attention to heat preservation and placed in a ventilated place.

3. Goldfish hanging orchid has higher requirements for fertilizer and water, and it is easy to yellowing leaves when there is not enough fertilizer and water. The phenomenon of aging. Organic fertilizer should be applied once a week or ten days apart, but different organic fertilizers should be selected according to different varieties.

4. In order to make the leaves more luxuriant, the soil should be changed every three months to ensure that there is enough space and nutrients for the reproduction and growth of goldfish orchids.

The culture method of hydroponic hanging orchid. Can Phnom Penh orchid be hydroponically cultured?

Plant information: Phnom Penh Cymbidium, recorded in the Liliaceae, belongs to Cymbidium. It is named because its leaf growth center is white and the edge is green, which is most suitable for home hanging appreciation. And the orchid is an evergreen plant, which is more suitable for indoor planting and becomes the best flower and plant on the top of the flower rack and indoor cabinet. So can Phnom Penh hanging orchids be hydroponically cultivated? What are the details of the culture methods of hydroponic orchids?

[morphological characteristics of Phnom Penh]

Phnom Penh's leaves are relatively broad, the color is tender green, more epiphytic on the short stem, and the leaves are fertile, succulent plants, the edge is green, the center of the leaves is white, unique, irregular growth, mostly curved and drooping.

Phnom Penh Cymbidium is a flowering plant, the inflorescence is small, the raceme can reach more than 30 cm, solitary, the flower color is white, and the florescence enters earlier and grows faster. Phnom Penh Cymbidium has the ability of reproduction, can grow small plants on the flower stem, can be natural, artificial transplant, the best way is water culture, strong ornamental value.

Benefits of hydroponics

Cymbidium, as a breeding plant, has strong viability, and the best way is hydroponic culture. This kind of cultivation way, the daily care is simple, but also can increase the ornamental, but also can raise goldfish inside, strengthen the indoor life atmosphere. Hydroponic Cymbidium has faster growth rate, stronger adaptability to season and climate, and faster reproduction speed, and this kind of culture method can put all its rhizomes, grass leaves and so on into medicine, and the plant value is stronger.

Hydroponic step

1. Container selection: water culture Phnom Penh hanging orchid, can choose double-layer glassware, can excess dregs impurities, utensils have a unique design of sagging bottle, to meet the Phnom Penh hanging orchid root sagging growth trend.

two。 Plant selection: Phnom Penh Cymbidium is mostly propagated by flowers, so we can adopt the method of split propagation, directly lift the roots out of the soil, wash them with clean water, clean the residual roots, old roots and rotten roots, prune the old leaves, diseased leaves and yellow leaves, etc., and then directly reserve 6-9 robust leaves for transplantation.

3. Planting on the basin: according to the different selection of utensils, planting and selecting double-layer glass bottles, you can hang down the roots of Phnom Penh hanging orchids through a plastic sieve, and then put them on the stone rice, while the lower bottles can add clear water and flower nutrient solution, and then put them directly in a cool place.

4. Maintenance and management: hydroponic Phnom Penh orchids need to be changed every 2-3 days during the survival period, while directly from soil culture to water cups, the watering times can be reduced. When changing water, the rotten root appears in the root, so it needs to be cut off and disinfected. When the root growth is more than 3 cm, an appropriate amount of nutrient solution can be added.

5. Fertilization: hydroponic Phnom Penh orchid, the survival period can be limited to once every three days, directly dilute the smooth nutrition, spray on the branches and leaves.

1. Soil cultivation: take soil as the cultivation method of Phnom Penh orchid, which has strong adaptability and is more resistant to drought, but the soil generally chooses sandy soil with certain drainage performance, loose and fertile.

two。 Watering: Phnom Penh hanging orchids grow, like semi-shady places, therefore, it is necessary to maintain the habit of "watering as soon as you dry". In the growth period, you need to water more appropriately, but avoid the formation of stagnant water in utensils, while in winter, you need to control the number of watering. Daily care, take spray watering, clean and take care of the page every day to avoid dust accumulation.

3. Lighting: Phnom Penh hanging delicate growth, avoid sunlight, but need to control the appropriate light in order to ensure healthy survival. In spring and autumn, direct exposure to the hot sun should be avoided, and astigmatism in the morning and evening can be chosen in summer. For the growth of Phnom Penh orchid, the leaves and roots will be brighter and more fertile in low light environment, and the light time can be increased appropriately in winter to avoid frostbite.

4. Humidity: Phnom Penh hanging orchid growth, like the semi-overcast environment, to avoid too low humidity, will cause dry phenomenon, and humidity to maintain about 15 degrees Celsius, winter, the temperature should not be less than 10 degrees Celsius.

5. Fertilization: Phnom Penh orchid, lack of fertilizer and water, easy to cause leaf tip yellowing, wilting and other phenomena, can be fertilized once every half month in its growing season, Phnom Penh orchid fertilization, the best choice is nitrogen fertilizer, avoid direct root fertilization, should be diluted first.

Excessive fertilization

Phnom Penh orchid fertilization, should be diluted, and the dosage should be controlled, and insufficient or excessive fertilization will affect the growth of Phnom Penh orchid, the leaves will appear dry, wrinkled, and the situation is serious, it will directly cause root rot. The yellowing phenomenon of leaf tip is mostly due to excessive fertilization or wrong fertilization methods, so it is necessary to stop fertilization in time, increase watering times, or directly change the soil.

Daily care

Due to the lack of professional knowledge of daily care, such as turning soil errors, not turning the soil for a long time, it will cause consolidation, which will not only directly affect the absorption of nutrients by Phnom Penh orchids, but also cause trouble to the soil turning work in the future, and the leaf tips will turn yellow and reduce the ornamental value. The rule of turning the soil every half a year and changing the soil every two years should be maintained. After the leaf tip appears yellowing, a small amount of alum fertilizer can be sprayed.

Due to excessive and insufficient daily light, it will also cause leaf tip yellowing and direct exposure to the scorching sun for a long time, which will cause the lack of water in the leaves, resulting in the phenomenon of drying up. Or lack of light, resulting in the decrease of chlorophyll, loss of gloss of leaves, yellowing phenomenon. Should keep the light time for about 4 hours a day, but not in the hot sun, long-term cloudy days, the orchid can be placed in the indoor light, such as incandescent lamp.

Basin soil influence

If you choose to use plastic bottles and pull soil for a long time, if you fail to loosen the soil in time, it will affect the air permeability and water permeability of the plant, the bottom soil is moist, the surface is dry, the plant is difficult to absorb nutrients, and after long-term stagnant water is difficult to dry, it will affect the respiration of the root and the leaves turn yellow naturally. At this time, the watering method can be changed, the amount of water can be controlled, and the soil can be loosened properly to keep the basin soil moist.

Step 1: container selection

Taking into account the daily care, container selection, mainly glass, with good transparency, can also be cleaned to observe the growth of the root.

Step 2: configuration of nutrient solution

The initial culture of Cymbidium can prepare its own nutrient solution, mainly adding calcium nitrate, magnesium sulfate, potassium chloride and ferrous phosphate, which are 1.8g, 0.187g, 0.62g and 0.0278g respectively, and dilute it with 1 liter of clean water.

Step 3: Cymbidium plant

Hydroponic Cymbidium can directly select the plants with strong roots from the soil culture, trim the roots, cut off the old roots, diseased roots and fibrous roots, and then clean up the plant shape. After the diseased leaves are removed, clear the soil from the roots of the Qingshui River, and the leaves are mainly leached, but avoid causing leaf damage.

Step 4: colonization

Place the orchid in the prepared glassware and fix it with glass ball, stone rice and other prize roots to avoid wind dumping and affect the cold shape of the plant.

Step 5: manage maintenance

The hydroponic orchid can be placed in a cool place to avoid direct sunlight. The temperature difference can be kept at 21-28 degrees Celsius and can be placed in low light.

Every other week, the nutrient solution can be replaced, and the professional nutrient solution can be purchased directly. At the same time, attention should be paid to the cleanliness of the water body. While changing water and nutrient solution, the root of the orchid can be properly cleaned to avoid soil mixing.
