Crab claw orchid leaves have leaf curling phenomenon, can be sprayed yellow leaves over and over gre

The crab claw orchid appears thin and yellow leaves, and the leaves are immediately restored to green and fat with a simple "three moves".

Learn to water the crab claw orchid in this way, the leaves are full and the flowers will not stop.

Give the crab claw orchid some "urine" to drink, the leaves are thick and oily, and they are tall and erect.

Crab claw orchid is a cactus plant native to the Brazilian rainforest. Because it grows epiphysically on large tree trunks or in dark, moist stone crevices in its native area, it needs shaded, moist environmental conditions for growth and development. It is a short-day plant that requires 8 to 10 hours of sunshine per day.

During the annual growth of crab claw orchid, there are two short dormant periods (one in the hottest summer and one in early spring after flowering) and two vigorous growth periods (one in mid-to-late May and one in early to mid-October). During the autumn growth season, attention should be paid to placing the potted crab claw orchid in the sunny window to let it fully receive the sun. It is best to build a plastic film shed in the corner of the balcony sheltered from the wind and sun, when the sun shines on the plastic shed, a microclimate is formed in the shed, which can ensure sufficient air humidity and is conducive to the growth of crab claw orchid.

On the other hand, the film shed can increase the temperature and keep warm, and it is generally about 5 higher than the room at night. If there is sun, the temperature is 5 10 times warmer than outside. In the cold winter wax moon, waste cotton tires or blankets can be used to cover the plastic shed in the evening, and they can be lifted at sunrise the next day.

In this way, the temperature can be kept at about 15 20 during the day and not lower than 5 8 at night, which is conducive to its growth.

The yellow leaves of crab claw orchid may be caused by too much light. At this time, cut off all its yellow leaves, and then move it to a semi-shady place to slow down and wait for it to recover. It can also be caused by insufficient fertilization.

At this point, apply some thin fertilizer to it, and increase the frequency of subsequent fertilization, changing to top dressing every 1-2 months. It can also be caused by overwatering. At this time, it is necessary to depot it, cut off the rotten roots and yellow leaves, and then plant it in the soil that is not easy to accumulate water for maintenance.

First, the sun is too strong

1. Reason: Crab claw orchid likes to grow in a well-lit bush environment, but it is not resistant to direct strong light. If it is placed in a place with direct sunlight, its leaves may turn yellow due to strong sunlight.

2. Treatment method: Usually put it in a position with sufficient scattered light to raise. If the leaves are yellowed, you need to cut off the yellow leaves with scissors, and then move it to a semi-shaded place to wait for it to recover.

Second, insufficient fertilization

1. Reason: It is a very fertilizer-loving flower, and it should be topdressed in time when maintaining. If it is not fertilized for a long time during the long season, its leaves may turn yellow due to lack of nutrients.

2. Treatment method: prepare some compound fertilizer, dilute it with water and pour it into the flower soil. After that, increase the frequency of fertilization and change to top dressing 1-2 times a month to provide it with nutrients.

3. Overwatering

1. Reason: It likes to grow in a slightly humid environment, but it is not suitable for growing in too wet soil for a long time. If it is overwatered, it may cause waterlogging of its roots, which in turn will cause it to have yellow leaves.

2. Treatment method: first dig out the shirt from the original flower soil, and use scissors to cut off the roots that have turned black and rotten and the leaves that have turned yellow. Then prepare some new soil that is not easy to accumulate water, plant the plants in it, and put them in a ventilated place for maintenance.

Autumn and winter is the time when the crab claw orchid grows buds, and the leaves of the crab claw orchid are soft and curly at this time, which is nothing more than the low ambient temperature and the root system! Because crab claw orchid is a greenhouse flower, it is not tolerant to severe cold, and it is an epiphyte of the cactus family, its own root system is not developed, and water accumulation and fertilizer damage are easy to cause root problems, and then the leaves are soft and curled.

What's the deal with the soft and curly leaves of the crab claw orchid?

1. The ambient temperature is low

Crab claw orchid is not cold-tolerant, and the flowering period needs an ambient temperature of about 15 to continue flowering, and the ambient temperature is low, and the temperature difference is too large, which is particularly easy to fall off the flower buds, and will also be accompanied by leaf shriveling, leaf curling and even leaf redness. In autumn and winter, when the local ambient temperature is lower than about 10, it is recommended that you move the crab claw orchid to a warm indoor astigmatism environment for maintenance.

2. Rotten roots or grafted rootstock rot with water

Crab claw orchid should avoid stagnant water, which can easily lead to root rot, and after rotten roots, due to the interruption of the normal supply of water and nutrients, the leaves will be shriveled and rolled due to dehydration and excessive consumption, and even aerial roots will grow on the leaf nodes. In the case of rotting rootstocks, the grafted crab claw orchid attached to its growth is the same as the crab claw orchid with rotten roots, which has cut off the water and nutrients, so the symptoms are the same!

3. Excessive fertilization, fertilizer damage and root damage

Autumn is the budding period of crab claw orchid, in order to make crab claw orchid flower more buds and flowers, after autumn, everyone will add some fertilizers to promote flowering, especially the so-called"All-purpose fertilizer"of phosphorus and potassium fertilizers, such as potassium dihydrogen phosphate. Although potassium dihydrogen phosphate does have the effect of promoting flowers and regulating growth, it should not be used excessively, it should be fully diluted before use, and used at a dose of 500-1000 ml of 1 gram mixed with water, and no more than 2 times a month.

4. Insufficient humidity and light conditions

If it is a crab claw orchid maintained in an indoor air-conditioned or heated environment, it is necessary to spray some foliar water on the leaves frequently with a fine spray, which can not only avoid water accumulation but also maintain a suitable temperature. Due to the lack of sunlight, the crab claw orchid cultivated indoors for a long time will also have dull, thinning and curled leaves, and the crab claw orchid can be moved to a bright place or scattered sunlight environment for maintenance, and it can generally return to normal soon.

In fact, it is not difficult to maintain crab claw orchid, the key is to control the temperature and ambient temperature, find the problem first from the root system to find the cause, in addition to excluding the main factor of rotten roots, and then from the environmental temperature and lighting conditions of the breeding environment to find the cause, it is generally not difficult to find the crux of the problem!

Many flower friends of the crab claw orchid flowering period has passed, some flower friends say that after flowering, the crab claw orchid leaves are thin and soft, looks very spiritless, here to share with you a few crab claw orchid breeding tips, timely remedy weak leaves quickly restore growth, leaves quickly restore the state of hypertrophic roots.

Many flower friends of the crab claw orchid flowering period has passed, some flower friends say that after flowering, the crab claw orchid leaves are thin and soft, looks very spiritless, here to share with you a few crab claw orchid breeding tips, timely remedy weak leaves quickly restore growth, leaves quickly restore the state of hypertrophic roots.

1. Check the potting soil and root system

If most of the stem nodes are weak and soft after the crab claw orchid, it is likely that there is a problem with the root system during the maintenance process, such as excessive watering and root rot, at this time it is necessary to check the potting soil, if the potting soil is very wet, it may be rotten roots, you need to depot to check the root system, if the rotten roots are serious, you can choose healthy leaves to re-cutting, if the potting soil is dry and only the leaves on the upper part of the stem nodes are weak, it is likely to be caused by long-term lack of water, and timely hydration can be relieved soon.

2. Cut the blades

Crab claw orchid is generally four to five stem nodes per branch, and the root system transmits nutrients from bottom to top, just enough to meet the needs of its tung growth and flowering, the longer the stem nodes, the more nutrients the plant needs, and the more branches are more, if the nutrients are not timely, it will cause the leaves of the branches to be thin and soft, especially the pregnant buds need to consume a lot of nutrients during the flowering period.

During this period, it has to give all its energy to the flower buds, so the leaves will be weak and soft after flowering, it is recommended to cut off one or two sections of the leaves at the top of the branches, minimize the loss of nutrients, and retain enough nutrients for the remaining stem nodes.

3. Increase fertilizer

Crab claw orchid will have a short dormancy period, and then enter the next season's growth period after the dormant period, you can supplement it with fertilizer twice in time at this time, mainly with nitrogen, phosphorus and potassium nutrients sufficient compound fertilizer, a few grains on the surface of the pot or shallow buried in the soil.

With the later watering fertilizer will be released slowly, for the root system to absorb and utilize the leaves with sufficient fertilizer**, will gradually become fattened and full, want the crab claw orchid to quickly recover its growth, but also to give it enough light, the spring sun is not too strong, just to meet the crab claw orchid's demand for light.

There can be two or three hours of direct light every day, and the leaf photosynthesis can not only accumulate nutrients for the plant, but also play a certain role in promoting the growth of crab claw orchid in the later stage.

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.
