What should I do if the leaves of Phalaenopsis are yellow, is it because I use too much fertilizer?

It may be that the fertilizer is used too much, or it may be that the temperature is not suitable and the sunshine is lacking, so the fertilizer should be applied appropriately, put it in a suitable place, and there should be a certain amount of sunshine, so that he can raise it very well.

Possibly yes, I think you can cut off the yellowed part of the Phalaenopsis leaves, and you have to replace a pot.

There are many reasons why Phalaenopsis leaves turn yellow: if it is caused by too much fertilizer, you should stop fertilizing and pour a large amount of water into the pot to dissolve the fertilizer accumulated in the soil in the water and drain it with the water. If it is caused by lack of water, it is necessary to add some water to the flower soil for the plants to absorb.

Phalaenopsis is noble and beautiful, known as the queen of orchid, and its ornamental value is very high. Moreover, the leaves of phalaenopsis can purify the air, so many flower friends will raise a phalaenopsis at home. In the process of breeding, sometimes the leaves of Phalaenopsis will turn yellow, which is mainly due to the following reasons, and the following is a detailed introduction to the reasons for the yellowing of Phalaenopsis leaves.

1.Lack of water. Phalaenopsis prefers a humid environment, and the air humidity should be maintained at about 70 even in winter when the flower buds are grown, and above 50 during flowering.

When there is a lack of water, the plant will not be accompanied by other symptoms except for the yellowing of the leaves. At this time, you can cut off the yellow leaves and replenish water in time, and usually water according to the principle of dry watering.

2.The light is too strong.

In yellowed plants, the yellowing of the leaves is generally yellow-green on the top part of the leaves on the sunny side, and the lower and backlit leaves are normal. At this time, the light intensity should be reduced, and the yellowed leaves should not be cut off, and they will slowly recover after reducing the light curing.

3.Root rot.

When the roots of the plant rot, the leaves will droop, yellow, and dry up, which is generally due to root rot. At this time, it is recommended to change the soil, and when changing the soil, the rotten roots are cut and erected. The main cause of root rot is excessive watering and excessive fertilization, and the amount of watering and fertilization should be controlled.

4.Pest.

When beetles, aphids, red spiders, etc. appear on the plant, the plant will also have yellow leaves, and insecticides can be purchased to kill it.

Summary. Once the leaves of the potted phalaenopsis kept at home are found to be yellow, it is necessary to pay attention to whether the leaves have become soft and whether the leaves have rotted? If only the leaves at the bottom of the plant slowly turn yellow and dry, and they start to turn yellow from the tip of the leaf and gradually wither, this is the normal aging of the leaves.

Once the leaves of the potted phalaenopsis kept at home are found to be yellow, it is necessary to pay attention to whether the leaves have become soft and whether the leaves have rotted? If only the leaves at the bottom of the plant slowly turn yellow and dry, but only if the tip of the leaf slips and begins to turn yellow and gradually wither, this is the normal aging of the leaves.

It can grow normally.

It can grow normally.

1. Normal yellow leaves are only with the same belt, that is to say, if the leaves at the bottom of the Phalaenopsis plant are normal yellow, the leaves are in a dry yellow state, and only one piece of mountain fiber old leaves is yellow, that is the metabolism of the reed, which only needs to wait for the leaves to wither, and break off the residual leaves in time.

2. In addition, if the water is too watered, the water moss is still waterlogged, or the unsuitable base crack is used for planting, the environment is too hot and humid or the fungus breeds, etc., will cause the leaves to turn yellow and rot. Waiting.

It may be caused by improper maintenance after transplanting, and there is also a condition caused by the normal metabolism of phalaenopsis. The top of the phalaenopsis orchid is normal with new leaves, but the lower leaves of the plant begin to turn yellow, which is caused by normal metabolism.

Treatment: Normal maintenance is sufficient, metabolic defoliation does not affect the growth of the whole plant, and new leaves will grow in the future.

What should I do if Phalaenopsis leaves turn yellow and soft?

1. Temperature control.

The optimum growth temperature of Phalaenopsis is 15 28, it is not tolerant to high temperature and severe cold, when the environment in which Phalaenopsis grows is greater than 32 and less than 5, its growth will be affected, therefore, more attention must be paid in summer and winter to ensure that it grows in the right environment.

Treatment method: control the temperature of phalaenopsis growth, in the hot summer can apply a layer of sunscreen or spray water on the surrounding ground to reduce the temperature, if necessary, you can place phalaenopsis in the air-conditioned room, as long as you pay attention to the tuyere do not face the phalaenopsis, do not turn on the air conditioning to pay attention to proper ventilation, in winter, phalaenopsis can be placed in a warm place, when the sun is mild in the morning in winter, you can give the phalaenopsis proper light to achieve the purpose of increasing the temperature required for growth.

2. Water and fertilizer control.

The new shoots of Phalaenopsis are reduced at the top, the young leaves are pale yellow, and the old leaves gradually turn yellow, which is caused by the lack of oxygen in the soil and the rot of some roots.

Treatment: Control water use and stop fertilization. The new leaves of the phalaenopsis grow thick and luxuriant, but the surface of the leaves is uneven, which is caused by over-fertilization.

Treatment method: Fertilizer should be stopped immediately, watered properly, several small plants can be transplanted into pots, excess fertilizer is consumed, and then the plants are taken out for pots and cultured.

3. Light control.

Phalaenopsis prefers semi-shaded, astigmatism environments, and strong light or long-term exposure to dark conditions will affect the photosynthesis of Phalaenopsis orchids, making the leaves yellow and soft.

Treatment: Usually pay attention to the astigmatism of Phalaenopsis orchid, pay attention to avoid direct strong light.

4. Pest control.

Insects, such as spider mites and scale insects, can also cause the yellow and soft leaves of Phalaenopsis orchids, so you should pay attention to maintaining air circulation (regular ventilation is conducive to reducing the occurrence of pests and diseases), clean up dead branches and rotten leaves, and observe the surrounding environment to ensure that the growing environment is clean.

Treatment: You can gently clean the leaves with a soft brush or spray insecticide + trime amino acid foliar fertilizer to remove insects.

Treatment: Normal maintenance is sufficient, metabolic defoliation does not affect the growth of the whole plant, and new leaves will grow in the future.

1.Increasing humidity Phalaenopsis has requirements not only for the humidity of the substrate but also for the humidity of the air during the growth period. If you are in a dry climate and low humidity for a long time, it is easy to cause the leaves to turn yellow. In this case, it is necessary to spray water frequently.

2.Blocking out strong light Phalaenopsis prefers semi-shady environments and is afraid of direct light. If you keep it in direct sunlight for a long time, the plant will be damaged.

3.Reasonable temperature control The growth of phalaenopsis has high temperature requirements, does not like high temperatures, and has poor cold tolerance.

4.Timely topdressing Phalaenopsis needs more nutrients during the growth period and needs to be topdressed in time.

The meaning is better, such as: Hong (red) luck head, fortune tree, peace tree, longevity flower, rich bamboo, junzi orchid, peony, sun god, bowl lotus, welcome pine; It is easier to raise, such as: hydrangea, black adamantium, cactus, ground roots, winter coral, cactus, cactus, aloe vera, weeping pot grass, spider plant, chrysanthemum, mimosa, etc.; Potted plants such as:

Rubber tree, plum blossom, apple, orange, pear, lychee, cherry, jujube, fig, osmanthus, monk fruit, passion fruit, elm, elm, etc.; It can be seen and used in medicine, such as: honeysuckle, daylily, wheat winter, indigo root, saffron, mint, ginseng, Polygonum multiflori, mandala flower, Boluohui and so on.

There are a lot of such as phalaenopsis, daisies, dahlias, hibiscus, evergreen, privet, heather, spring flowers, cypresses, cedars, etc., including a variety of grasses, a lot of indispensable varieties of landscaping, which has stimulated the large-scale formation of the industrial chain of special nutrient soil, special fertilizer, special medicine and so on. It is best to choose two points for the time of medication.

1. If it is necessary to ventilate in the shed, either two hours before the vent or two hours after the vent;

2. Look at the weather forecast, and take medication one or two days before encountering sudden changes in weather and temperature.

Before taking the medicine, be sure to wash the medicine pot first, if it is time to use the medicine but encounter cloudy days, you can add 50 grams of potassium nitrate when using the medicine to increase the recovery effect of the disease.

How to raise Phalaenopsis orchids, keep this trick in mind, the roots are strong and the leaves bloom more!

Reason: If the Phalaenopsis grows in an environment where strong light is exposed, its leaves will be sunburned, and it will not only turn yellow but also become very soft.

Solution: The yellow leaves should be cut off in time, and then placed in the shade for about a week, and the leaves will recover. When maintaining it, it should be kept in a well-lit but not strong place.

Reason: The plant is suitable for growing in a slightly humid environment, and it is very afraid of waterlogging. If you water too much or too often, it will cause stagnant water, and the leaves will turn yellow when the roots of the plant rot.

Solution: This is to tilt the potting soil to let the stagnant water run out, and loosen the soil properly, and then put it in a place with good air circulation. The amount of water should be controlled for daily watering, and attention should be paid to sheltering during the rainy season.

Reason: Usually the amount of fertilizer applied to it is too large, the root system of the plant can not absorb it, there may be fertilizer damage, the root system can not deliver nutrients normally after being burned, and the leaves will also turn yellow.

Solution: It is necessary to stop fertilizing immediately and water properly to speed up fertilizer loss. If the situation is more serious, it is best to replace it with new nutrient soil and replant it.

Precautions: 1 Excessive watering: Friends who cultivate phalaenopsis are always worried about the lack of water in Phalaenopsis, regardless of whether the cultivation medium is dry or not, watering every day, resulting in serious root rot.

2. The temperature is too low: Usually the time when the phalaenopsis flowering plants are on the market in early spring, and after buying home, they are generally placed in the living room and other places to enjoy, although the day temperature in these places is enough, but the night temperature is slightly too low. On the other hand, most professionally cultivated orchids are in well-equipped greenhouses, and the temperature and humidity at home are slightly insufficient, so that the growth of the plants tends to weaken day by day.

Therefore, sometimes no matter how well maintained the orchid is, there are still times when the orchid does not bloom.

3. Excessive fertilization: apply fertilizer when there is fertilizer, and do not pay attention to the concentration, thinking that it will grow faster after fertilization. It should be noted that phalaenopsis should be applied with thin fertilizer, which should be used in small amounts and many times. Remember that "tonic" should not be excessive, otherwise it will backfire.

4. Small plants and large pots: I think that using large pots can give Phalaenopsis a relaxed environment and sufficient materials. After its practical large pot, the aquatic plants are not easy to dry, and it should be known that Phalaenopsis likes to ventilate, and the ventilation is comfortable.

5 Flower dry bag: most of the Phalaenopsis is now urged to come out, after leaving the base, it is easy to have a dry bag problem after the environment changes, at this time do not think that it is dry, do not water more, but increase the humidity in the room, control the temperature in the room, the temperature can not be too high. When buying flowers, try to choose thick petals.

6.Phalaenopsis is mostly cultivated in the base greenhouse, after the family potted phalaenopsis is bought and raised, it should be as far as possible and the environment of the base greenhouse cultivation is not too different, the temperature is 20-25 degrees, more ventilation, and it is best to increase the indoor humidity in winter.

Orchid is very simple, first sterilize the flower pot and orchid before the pot, prepare orchid soil, small stones and soft matter ratio 6:4, then plant, and then pour the disinfectant water into the planted orchid pot, put it in a ventilated, cool and short-day environment, water once every two days on a hot day, water once every four days in winter, and spray water once with a watering can in the morning and evening in summer. Put it in the room in winter.

It is disinfected once every half a month and changed once every two years. Chlorothalonil is used for disinfection, and everything is available in general pharmacies, as long as it is used for disinfection, mixed with water. Personal experience.

Please understand any inappropriateness.

Rotten roots are generally blistered at the roots, and new leaves indicate that the plant is still alive, you can dig out the whole flower, cut off the rotten roots, dry it a little, and replant it, be sure to ensure that the potting soil is well drained and does not accumulate water.

It is also necessary to pay attention to the growth environment of phalaenopsis:

Phalaenopsis prefers high temperature, high humidity, and ventilated environments; It is not resistant to waterlogging, semi-shady environment, avoid direct sunlight, avoid stagnant water, be afraid of cold, and the suitable temperature for growth is 22 28, and the overwintering temperature is not less than 15.

Artificial light supplementation is beneficial to leaf temperature, microclimate, and seedling growth, and can reduce plant loss. Its features are as follows:

1 Seedling growth in the hole tray: promote rapid growth and reduce the loss of orchid plants.

2 Growth Stage: Promote rapid growth and better development.

3. Flowering stage: It is helpful for the development of flower stalks and flower buds, reduces flower bud loss and increases quality. In winter, phalaenopsis requires at least 12 to 14 hours of light with a light volume of 3500 to 4000 lux, making it suitable for the use of artificial light sources.

Using too much light in sunny weather will cause the leaves to turn red, resulting in growth arrest. In addition, the orchid strain is maintained with a dark period of at least 8 hours to determine the absorption of carbon dioxide.

Don't worry about the dry root system of phalaenopsis, maintain it like this, new roots will pop up wildly, and flowers will burst into pots!
