Why are crab claw orchid leaves dark green? Crab claw orchid leaves are not green why

The leaves of the crab claw orchid are not green because the environment is too different from the ideal environment, such as insufficient nutrients, too little humidity, cold current invasion, soil compaction, pests and diseases, etc., the pot soil is too dry There are two important elements worth noting, the crab claw orchid will experience a period of dormancy after the belt, the plant stops growing, and at this time too much watering, resulting in the potting soil is damp, the leaves are yellow, and they become not green.

In spring and summer, the sun is strong, and if you don't shade it when you care outdoors, the leaves will not turn green. Crab claw orchid leaves are not green treatment method:

1. Reasonable fertilization, crab claw orchid has little demand for fertilizer, and imitation jujube needs to be supplemented with fertilizer in time when it enters the budding stage to promote the normal differentiation of flower buds. When there is a shortage of fertilizer, go directly to buy potassium dihydrogen phosphate, directly water it with water, and remember that the concentration should be low.

2. Control the amount of water, watering should be controlled, not too often watering, and watering if the surface of the potting soil is dry. In winter, water according to the potting soil, only dry and not wet.

3. The humidity is moderate, and the indoor maintenance of crab claw orchid should not make the plant too close to the air outlet of the warm Daqing gas sheet or the air conditioner, otherwise the foliar water will evaporate quickly, the leaves will be dehydrated, and gradually the whole plant will wilt and turn yellow.

4. Pest control, the main pests of crab claw orchid are red spiders and scale insects, once found, remove the leaves in time and spray them with drugs.

Crab claw orchids generally suffer from diseases. Generally, the types of crab claw orchid diseases include rot disease, anthracnose and leaf blight. The impact on crab claw orchid is still relatively large, so let's talk about the types of these diseases and solutions.

Enumerate: 1: Rotting disease.

It usually occurs in the roots of crab claw orchids, and in the early stage of the disease, it will produce brownish-green yellow spots, which are irregular. Later, in the later stage, the lesions will turn dark brown, and if they are sunken, the tissues under the skin will decay and dry, and there will be black granularities. Prevention and control methods:

The amount of water should not be too large at a time, nor should it be too diligent, otherwise it is easy to produce these diseases. In the early stage of the disease, it should be prevented, and it is necessary to spray zebsen zinc to avoid further infection.

2: Leaf spot. It usually starts at the edge of the leaf, and at the beginning of the disease is gray spots, then expands to a dark brown color, and finally these spots slowly dry up and mildew spots appear.

Solution: Once infected with the disease, these diseased leaves should be cut off in time, so as to reduce the source of infection, and prevention and control should be carried out in the early stage of the disease, such as the use of some drugs, the general drug can choose 800 times the liquid pentachloronitrobenzene fungicide, or directly apply the drug to the leaves of the crab claw orchid.

3: The so-called rust, rust spot, the incidence of the disease and the above symptoms are similar, generally will not have an impact on the roots, the control measures are to cut off the diseased leaves, do not cut off the diseased leaves. If you want to use drugs, it is generally recommended that these two drugs, methyl tobuzin or carbendazim, are generally diluted 800 times.

However, it is also necessary to pay attention to the frequency when spraying, generally spraying once in the early stage of the disease, and keep spraying once every 5-7 days. Usually just 2-3 sprays in a row are fine.

Extended information: It is an epiphytic succulent plant of the cactus family, shrub-like, with overhanging stems, multi-branched and thornless, old stems lignified, and young stems flattened; bright green or slightly purple, truncated at the apex, flowers solitary at the top of the branches, symmetrical on both sides; calyx apex separated; Corolla several rounds, stamens numerous, berry pear-shaped.

1. The leaves of crab claw orchid are very small, mainly because there is no timely repotting and pruning during the growth period, because the branches are too long and too dense, resulting in malnutrition, so the leaves are small and yellow. Crab claw orchid likes fertilizer, and the flowering period is as long as 4 months, into the autumn to change the pot of crab claw orchid, appropriate fertilizer, the growth period to timely thin off too long, too dense branches, each branch to retain 4-6 leaves on it, timely pruning to promote the differentiation of side buds, flowering period can bloom more. For all potted plants, autumn is a time to overcome malnutrition during the summer dormancy and prepare for winter.

2. Crab claw orchid is an epiphytic succulent plant, the branches are composed of leaves, and its own root system is not developed, so the crown width of crab claw orchid should not be too large, and large potted plants need to be grafted with cactus plants! Like the one below, the branches are too long and too dense! The branches are too long and too dense, which is not conducive to growth and ventilation, and the leaves will become smaller and smaller, and the flower buds will be few.

The crab claw orchid leaves are red, what's going on? Will it affect flowering? Or is there something missing?

Crab claw orchid is a cactus family, belongs to epiphytes, potted plants do not need too large pots, the soil should be permeable to water and breathable, otherwise it is easy to accumulate water and rot roots, the flowering period of crab claw orchid is about 10 months - February of the next year, the flowering period should not be moved often as much as possible, environmental changes will affect flowering.

It is necessary to replenish fertilizer and water in time after each flower failure to promote its renewal and rejuvenation. Sudden exposure to the sun should be prevented. Watering in time to ensure water supply.

In other words, this time is the time when the crab claw orchid blooms? Therefore, the bulge on your top should be the small bone of the crab claw orchid. This aunt will bloom in a while.

Summary. The flowers of the crab claw orchid are usually white or light yellow, but its leaves are dark green. As a result, the contrast between the green leaves and the white pale yellow flowers of the crab claw orchid makes it a beautiful houseplant.

The knicky flowers of the crab claw sedan orchid are usually white or light yellow, but its leaves are dark green. As a result, the contrast between the green leaves and the white pale yellow flowers of the crab claw orchid makes it a beautiful houseplant for the Closed Acre.

I'm sorry I don't understand, but can you elaborate on that?

The leaves of the crab claw orchid are usually dark green, and the flowers may be red, pink, white, purple, yellow, etc. Because the flowers of the crab claw orchid have a unique shape and the leaves are fat like crab claws, it is named "crab claw orchid". It should be noted that the crab claw orchid has a short flowering period, but the flowers are very beautiful, and it is known as the "queen" of orchids.

Reason: Crab claw orchid needs proper watering and fertilization during the maintenance process, once you do not pay attention to the good dosage, it will lead to root rot, affect the delivery function, water and nutrients are difficult to supply, and the leaves will cause redness.

Solution: Pay attention to control watering and fertilization, dig out the plants to check the roots, cut off the rotten roots, and replant and maintain.

Reason: If the soil is not changed for a long time, the soil will be alkaline, and the growth of the plant will be affected, resulting in red leaves.

Solution: If you find that the soil is not right, you need to replace the soil in time and replace it with loose acidic soil.

Cause: If the leaves turn red in winter, it is likely that you have suffered frostbite.

Solution: Pay attention to keep warm in winter, not too cold, and the surrounding growth temperature is best kept at about 10 degrees.

Reason: If it is kept in a place with strong light, it will cause the leaves to turn red under the sun burn, not only the exposure to the sun, but also the redness of the leaves in a dark state if the sun is not seen for a long time.

Solution: It is necessary to control the light in maintenance, see the light in time when the sun is lacking, and take shading measures when the light is too strong.

Reason: Long-term non-fertilization can also lead to nutrient loss, especially the lack of phosphate fertilizer, which will cause the leaves to turn red.

Solution: It is necessary to supplement phosphate fertilizer in time according to the needs of growth to meet the demand for nutrients.

Redness of the leaves of the crab claw orchid is not a normal phenomenon, it may be due to rot in the roots of the plant, or because the soil is alkaline, or it may be due to a lack of water.

This is not normal, from which it can be seen that there is a shortage of water, there are pests and diseases, the leaves are dry, the watering is too little, and there is a drought.

The causes of redness of the leaves of crab claw orchids are: rotten roots and unsuitable soil.

1. Root rot

Crab claw orchid is a plant of the cactus family, in the process of maintenance, if too much watering leads to water accumulation in the root system, the roots will rot, water and maintenance can not be transported to the aboveground parts, the plant lacks nutrients, and the leaves will be red. The amount of watering should be controlled, and if the root system is already rotten, the rotten root should be cut off and repotted.

2. Soil discomfort

The soil suitable for the growth of crab claw orchid is loose and fertile, and the acidic soil with good air permeability will lead to alkaline soil if the soil is not changed for a long time, and the plant growth will be affected, and the leaf color will be red. At this time, you can replace the soil in time, or add some lemonade when watering, and mix some acidic rotten leaves when fertilizing.

Conservation method of crab claw orchid

1. Scientific watering

The leaves of crab claw orchid have a certain water storage capacity, can tolerate drought but not waterlogging, during the maintenance and management period, the amount of watering is controlled according to the growing season, watering every 3 days in spring and autumn, the water evaporates quickly at high temperature in summer, watering every morning and evening, and the growth is slow in winter, watering every 10-15 days.

2. Lighting conditions

Crab claw orchid is a short-day succulent plant, like to grow in a warm environment, ensure no less than 8 hours of light every day, so that the leaves can fully photosynthesize, accumulate nutrients while also controlling the flowering time, shade and sun protection in summer.

3. Regularly change soil

Crab claw orchid has higher requirements for soil, and the potting soil needs to be replaced once in March every spring, and the well-rotted cake fertilizer is added with humus, garden soil, and river sand, and the nutrient soil is fully mixed and prepared, and a layer of fine sand is laid at the bottom of the pot to increase water permeability.

Redness of leaves of crab claw orchid is relatively common, and too much light, drought, too low temperature, and too large temperature difference will cause redness of leaves

As long as the redness of crab claw orchid is not too bad, and the maintenance is improved in time, the problem is not big, and it can quickly turn red to green. Some grafted crab claw orchid leaves are red, which should be noticed, which may lead to the death of the whole plant. The most feared thing about the redness of the grafted crab claw orchid leaves is that there is a problem with the grafted position or the rootstock is rotten, which will also lead to the redness of the leaves and the death of the whole plant severely.

The problem of grafting position refers to the poor connection between the scion and the rootstock, the connection part is relatively small, and the nutrient water is insufficient, resulting in the loss of water and nutrient and redness of the leaves, the growth rate is very slow, the leaves are thin and weak, and it is not easy to flower. If the grafting site does not heal well and the leaves are red, it can be re-grafted. If the rootstock is rotten roots, it is necessary to prune the roots after depotting, sterilize and repot.

Cultivation method of crab claw orchid:

Crab claw orchid is a flower that needs water and generally blooms in autumn and winter, so you should pay attention to watering in autumn and winter, and water more during the flowering period to replenish water. The temperature of the growing environment of crab claw orchid needs to be kept at about 20, when the temperature is too low, it will affect the opening of the plant flowers below 10°, and if the temperature is too high, the growth of the plant will be stagnant, so you can put the plant indoors in summer.

The remedies for redness of crab claw orchid leaves are as follows:

1. Root rot.

Reason: Crab claw orchid needs proper watering and fertilization when maintaining, once you do not pay attention to the dosage, it will cause the root rot of crab claw orchid, affect the transportation function, water and nutrients are difficult to supply, and the leaves will turn red. Method:

Pay attention to controlling watering and fertilization, dig out the roots of the plant to check it, remove the rotten roots, and replant and maintain it.

2. The soil is alkaline.

Reason: If the soil is not changed for a long time, the soil will be alkaline, and the growth of the plant will be affected, resulting in the leaves turning red. Method: It is necessary to replace the soil in time and replace it with loose acidic soil.

3. The temperature is low.

Reason: If the leaves turn red in winter, it is likely to be frostbite. Method: In winter, you should pay attention to keep warm, do not overcool, and the temperature of the surrounding growth is best kept at about 10 degrees.

4. Inappropriate lighting.

Reason: If it grows in a place with strong light, exposure to the sun will make the leaves red, not only because of sun exposure, not being exposed to the sun for a long time, and being in a shady environment, will also cause the leaves to turn red. Method:

When maintaining, it is necessary to control the light, see the light in time when the sun is lacking, and take shading measures when the light is too strong.

5. Nutritional deficiencies.

Prolonged absence of fertilization can also lead to nutrient loss, especially phosphorus deficiency, which can lead to red leaves. According to the growth needs, phosphorus fertilizer should be applied in time to meet the nutrient demand.
