Why do the leaves of my anthurium turn yellow and fall off

The appearance of yellow leaves, depending on the characteristics of its occurrence, has the following situations:

One is water yellow. Caused by over-frequent watering, it is characterized by no obvious change in old leaves and yellowing of young leaves; This should be done with immediate water control;

The second is dry yellow. Caused by lack of water and drought, it is characterized by the first yellow leaves from the bottom up, if the lack of water for a long time, the whole plant will be yellow, and even die, should be watered in time;

The third is fat yellow. Caused by excessive fertilization or high concentration; It is characterized by thick, shiny, and uneven young leaves; Fertilizer, cultivation and watering should be controlled;

Fourth, hungry yellow. It is caused by insufficient fertilizer, low fertilizer concentration, and long fertilization interval; It is characterized by the first yellow of young leaves and young stems, and if you do not fertilize in time after seeing this phenomenon, it will also cause the whole plant yellow leaves or even die; For flowers lacking fertilizer, avoid applying a large amount of thick fertilizer at one time, so as not to cause root burning;

Fifth, iron deficiency yellow leaves. Due to the great change of soil fertility conditions, the phenomenon of yellow leaves often occurs in greenhouses, which is characterized by obvious young leaves, light old leaves, yellow mesophyll, green leaf veins, and the formation of a typical network. It can be solved by applying ferrous sulfate aqueous solution, and the method is: 7 parts of cake fertilizer, 5 parts of ferrous sulfate, and 200 parts of water are prepared into multiple liquid water.

There are the following ways to solve the yellowing of anthurium leaves:

1. The leaves turn yellow due to their own growth reasons: this is a normal phenomenon of plant metabolism, as long as the yellow leaves are cut off, and then the inside of the pot can be cleaned;

2. Yellowing of leaves due to bacterial infection: mix garlic juice or buy special drugs** to solve this problem;

3. Yellowing of leaves due to overwatering: Overwatering will reduce the chlorophyll density of the leaves, which will also cause the color of the leaves to become lighter or even yellow.

Anthurium is a tropical plant, there are certain requirements for light, temperature, humidity, and watering and fertilization are very careful, if improper maintenance will cause the anthurium leaves to turn yellow, affecting the ornamental effect.

The best growth temperature of anthurium is between 20 and 30 degrees, if the temperature is relatively low, it will cause the leaves to turn yellow, especially if the temperature is too low, it will cause frostbite to the leaves, and the leaves may be frostbitten, so special attention should be paid to controlling the temperature when maintaining the anthurium, and if the anthurium can be moved indoors in winter.

Excessive watering will also lead to yellow leaves, although anthurium is a tropical plant, but too much watering will lead to water accumulation in the potting soil, anthurium rotten roots, root rot is not easy to detect, the manifestation is that the leaves gradually turn yellow. If not watered enough, it can also cause the anthurium leaves to turn yellow. Therefore, watering should be moderate, and watering until the soil is slightly moist.

Anthurium also needs to be supplemented with nutrients in time during the growth period, if the nutrition can not keep up, it will also cause the leaves to turn yellow, especially after flowering, to supplement fertilizer in time, to avoid giving too much thick fertilizer, to avoid fertilizer injury, if you accidentally fertilize too much will also cause the leaves to yellow, so pay attention to the concentration and frequency of fertilization.

You can use water-soluble fertilizer or organic fertilizer, and it is best to choose a fertilizer that is better absorbedNo matter how much fertilizer is applied, if the plant is not well absorbed, it is also a white ride, Zhulu Qingpai Green Leaf King is a plant nutrient solution, containing nitrogen, potassium and phosphorus, to ensure sufficient nutrition, and it is also a direct injection type that is very easy to use, and the atomization design allows the plant to better absorb.

We maintain it indoors, there is often the phenomenon of water accumulation in the potting soil, after the accumulation of water, the plant will rot the roots, and the nutrients will not reach the leaf part after the root rots, and the leaf yellowing will occur, at this time we can take the plant off the pot, look at the growth state of the roots, if there are not many rotten places, you can cut off the rotten part slightly, put it in a ventilated and cool place and wait for the pot soil to dry in the water; If the rotten part of the roots is more serious, the roots of the plant should be re-pruned in time, disinfected after changing the soil, and then replanted, waiting for the plant to recover on its own.

Anthurium plants can not stand the burning under the refraction of sunlight for a long time, and will produce yellow spots, so the plants should be semi-shaded in time, or taken into a bright place indoors, and only need to give appropriate scattered light.

Observe the growth environment of your own anthurium, if it is in a dark corner, it is because there is no light to produce yellow leaves, to replenish the light in time, you can take it to the window or balcony.

Apply raw fertilizer or the amount of fertilizer is too large and too concentrated, it is necessary to dilute it with water in time, and discharge the excess fertilizer through irrigation, if it cannot be discharged, it is necessary to change the soil and replant.

Anthurium fertilizer deficiency will also cause yellow leaves, to add rotted liquid fertilizer or replace nutrient soil as soon as possible, usually pay attention to thin fertilizer when maintaining, do not be too thick.

If the plant is left in a place with little light or shade for a long time, it will stunt and its leaves will turn yellow, and it will not bloom and no new leaves will grow. At this time, we need to put it in a sunny place, such as a balcony or yard. But if the sun is too strong in summer, it is still necessary to do some shade treatment.

Improper temperature is likely to cause its leaves to turn yellow, especially in winter, because if the temperature is too low, the leaves will turn yellow, but if the temperature in the house is too high in winter, the evaporation of water will be faster, and the lack of water in the roots will also cause its leaves to turn yellow. Therefore, we must ensure that the indoor temperature in winter is in a relatively stable state, not too high and not too low.

Improper watering or fertiliser can cause it to turn yellow. If the water is not properly watered, it is necessary to water properly, pay attention to the water can not be too much, not too often, and there can be no stagnant water in the pot, otherwise it is likely to cause it to yellow leaves due to rotten roots. If too much or too little fertilizer is applied, its leaves will also turn yellow.

If you fertilize too much, don't fertilize anymore and water the pot; If there is too little fertilization, it is necessary to fertilize in the right amount, and the right amount of trace elements can be added to the fertilizer.

1. Light. 2. Temperature.

3. Humidity. 4. Moisture.

1.Light: Anthurium is a semi-shade-tolerant plant that can be placed on a sunny south balcony in winter and in a place with bright scattered light in the home in other seasons.

In the case of outdoor farming, the Xi'an area needs this shade from April to September to avoid direct sunlight, otherwise it will cause solar burns. At the same time, it should also be avoided in a place that is too shady, otherwise it will affect the flowering of anthurium, which is also the cause of yellowing of leaves.

2.Temperature: Anthurium cultivation has high temperature requirements, too low or too high will cause the leaves of Anthurium to turn yellow.

The most suitable temperature of anthurium is about 18 to 30 degrees, and the highest temperature cannot exceed 35 degrees, when the temperature is lower than 15 degrees, the Buddha flame bud of anthurium is not easy to form. Home farming, as long as the room temperature is not lower than 10 degrees, it can be made not to be affected by colding.

3.Humidity: Next, let's talk about the humidity of anthurium farming, anthurium has aerial roots, and can absorb moisture in the air through aerial roots to maintain its own growth, so air humidity is very important for anthurium.

The most suitable air humidity is 70 to 80 percent, the lowest should not be less than 50 percent, in the winter indoor breeding air is too dry, the anthurium will appear yellow, the edges curl and other phenomena. Therefore, we should ensure the humidity of the indoor air, but we should pay attention to the humidity when the temperature is relatively low, and the humidity should not be too high.

4.Moisture: In the process of breeding, the water should be dry and wet, and in winter, it is necessary to reduce the watering of the potting soil appropriately and keep the potting soil moist.

If there are yellow leaves in the anthurium, after ruling out the above problems, it is necessary to consider whether it is because of too much watering that causes water in the pot, resulting in rotten roots. We want to be able to remove the water in time and put it in a well-ventilated environment.

Anthurium is a plant with very high ornamental value, its flowers are unique, there are Buddha flame inflorescences, the color is bright and gorgeous, the fiery red flowers set off the turquoise leaves, it looks very good-looking, but the improper maintenance of the anthurium will also appear leaves yellowing, rotten roots, etc., what to do if the anthurium leaves are yellow? Let's take a look at the seven reasons and solutions pointed out by experts:

Causes of yellowing of anthurium leaves1Metabolism.

If you find that the leaves of the anthurium are yellow, you should pay attention to the condition of other leaves, if the leaves are bright yellow-green, and the flowers are growing well, it means that new leaves are growing, and it is normal for old leaves to turn yellow and fall.

Causes of yellowing of anthurium leaves2The soil is not comfortable.

In most areas of the north, the medium and water contain more salt and alkali, and due to the lack of soluble iron that the plant needs to absorb, the leaves will gradually lose green and turn yellow. Solution: Use oxalic acid and other treatment media and watering water.

Analysis of the causes of yellowing of anthurium leaves.

Causes of yellowing of anthurium leaves3Overwatering.

The new leaves of Anthurium are yellow, and the old leaves are normal, which is generally due to excessive watering and too frequent watering, which will cause the medium in the pot to be too wet for a long time, and even accumulate water, resulting in the rot of some fibrous roots, hindering normal respiration and absorption of nutrients, causing the leaves to gradually turn yellow and fall off. Solution: Water normally.

Causes of yellowing of anthurium leaves4Air dry.

In winter, when the indoor flower air is too dry, the leaf tips are often dry and yellow, or the leaf edges are scorched, or the leaves are scorched and the edges are curled. Solution: According to the growth characteristics of anthurium, increase the air humidity appropriately.

Causes of yellowing of anthurium leaves5Excessive shading.

If the anthurium is left in a shaded place or a place with insufficient light for a long time, it will cause weak growth, and the leaves will be thin and yellow, and there will be no or very little flowering. Solution: According to the growth characteristics of anthurium, increase the light intensity appropriately.

Anthurium leaves are yellowish.

Causes of yellowing of anthurium leaves6The temperature is not suitable.

In winter, if the indoor temperature is too low, the leaves will turn yellow; If the room temperature is too high, the plant will be overtranspiration, and the root water and nutrients will be insufficient, which will also make the leaves yellow. Solution: Keep the temperature of the spike in the greenhouse relatively stable.

Causes of yellowing of anthurium leaves7Uneven fertilization.

Lack of fertilization, or not changing pots and soil for a long time, the lack of nutrients such as nitrogen in the soil leads to thin branches and leaves, thin and yellow leaves. In addition, excessive fertilization will also cause new leaves to be hypertrophied, uneven, and at the same time the old leaves are dry and sharp, scorched and fall off, at this time, the people should immediately stop fertilization, increase watering, and remove part of the old soil, replace it with new cultivation soil, and carry out normal management.

What to do if anthurium leaves turn yellow? Now everyone knows it, the cultivation of anthurium is still relatively simple, even if there are yellow leaves, etc., as long as we observe carefully, we can find out what causes it, and take targeted measures to solve it naturally, raising a beautiful pot of anthurium. The reasons for the yellowing of anthurium leaves and their solutions are shared with you here, for more information, please pay attention to the flower column of Ailianshuo Flower Network.

<>1. Environmental mutation leads to yellowing of anthurium leaves: environmental mutations include soil discomfort, and most areas in the north contain more salt and alkali in the medium and water, and the leaves will gradually lose green and turn yellow due to the lack of soluble iron that the plant needs to absorb in the medium. Workaround:

Oxalic acid and other treatment media and watering water are used.

2. Excessive watering leads to yellowing of anthurium leaves (water yellow): too much watering and too frequent will cause the medium in the pot to be too wet for a long time, and even accumulate water, resulting in the rot of some fibrous roots, hindering normal respiration and absorption of nutrients, and causing the leaves to gradually turn yellow and fall off. Solution: Water normally.

3. Long-term lack of water leads to yellowing of anthurium leaves: Long-term lack of water will reduce the rate of photosynthesis and cause the leaves to turn yellow and dry. Solution: Immediately pour an appropriate amount of water.

4. Dry air leads to yellowing of anthurium leaves: When the indoor air is too dry in winter, the leaf tips are often dried and yellow, or the leaf edge is scorched, or the leaves are scorched, and the edges are curled. Workaround:

According to the growth characteristics of anthurium, increase the air humidity appropriately.

5. Insufficient sunlight causes yellowing of anthurium leaves (lack of light yellow): If Anthurium is placed in a shade or a place with insufficient light for a long time, it will lead to weak growth sensitivity, thin and yellow leaves, no flowering or little flowering. Workaround:

According to the growth characteristics of anthurium, increase the light intensity appropriately.
