What causes the yellowing of the leaves of anthurium?

In the process of raising anthurium, many people will make the leaves of anthurium slowly yellow. Probably because of the number of times you water, too often. Anthurium is exposed to sunlight at a relatively low temperature.

The environment in which anthurium is cultivated is not humid enough. Lack of timely fertilization leads to malnutrition in anthurium. All of these causes lead to the appearance of yellowing.

First of all, we must have a clear understanding that the suitable growth temperature of anthurium is generally controlled at about 20 or 30 degrees. If the temperature of the anthurium is too low, too high is not conducive to the growth of the anthurium. If the temperature is too low, it will cause the leaves of the anthurium to slowly wither and turn yellow.

And if it is a few degrees below zero, anthurium can also get frostbitten. And the environment where the anthurium is located, try to stay away from air conditioners, heaters, water heaters, radiators and other places, otherwise the leaves will also turn yellow. <>

The most common phenomenon that causes the leaves of Anthurium to turn yellow is to water too often. Because many people are afraid of the lack of water in anthurium, they water it frequently. If you have too much water, not only will you not be able to replenish nutrients, but you may also have rotten roots.

In this way, the yellowing of anthurium leaves is also a natural occurrence. So before watering the anthurium, be sure to check the moisture of the soil. If the soil is really dry, then at this time, water it in moderation.

But if it is wet all the time, then there is no need to water it at this time. <>

Anthurium itself prefers a humid environment, if the anthurium is in a dry environment, lack of moisture, will also cause the leaves of the anthurium to turn yellow. Therefore, it is important to control the humidity environment in which the anthurium is located, and it is best to put a humidifier next to it. Special attention should also be paid to fertilization.

It is necessary to control the concentration of fertilizer, and do not apply fertilizer frequently. The soil for cultivating anthurium must be sufficiently fertilized, and it must have good light transmission and drainage performance. Only in such an environment can anthurium thrive.

It may be due to the lack of fertilizer in the soil, lack of nutrients and cause yellowing of leaves, or long-term exposure to the sun, which will also cause yellowing of leaves, and if there is no watering for a long time, it will also cause yellowing of leaves due to lack of water.

The yellowing of the leaves of the anthurium is due to insufficient light conditions, not regular watering and fertilization, resulting in malnutrition, insufficient soil and poor drainage of the pots.

The yellowing of the leaves of Anthurium may be due to insufficient light and effective photosynthesis, poor soil air permeability, or excessive alkalinity of the soil.

The yellowing of the leaves of anthurium is usually due to insufficient light, and the leaves cannot carry out enough photosynthesis to synthesize more nutrients, and they will turn yellow, and even fall off in severe cases. The sudden drop in temperature will also cause the leaves of the anthurium to turn yellow, in which case the temperature needs to be adjusted to 15 or more. If it is because of the unreasonable use of water and fertilizer, you can change the watering to water every three days, and apply thin fertilizer frequently.

1. Enhance lighting.

If the anthurium is kept in a dark place for a long time, the leaves of the anthurium will not be able to photosynthesize. The plant itself is stunted, and the leaves will gradually turn yellow, and there will even be no flowering and no leaves.

In this case, you need to put the plants in a sunny place, move them to the yard or balcony, and if the light is too strong in summer, you also need proper shade to avoid the plants being burned.

2. Maintain temperature.

Usually in the case of a sudden drop in temperature, the leaves of the anthurium will be frostbitten, and the leaves will gradually turn yellow, and even fall off at the slightest touch.

When maintaining anthurium in winter, it is necessary to keep the surrounding temperature not lower than 10, and try to keep it above 15, and being in a relatively stable state is conducive to the growth of anthurium.

3. Control water and fertilizer.

Improper watering or fertilization is the most likely cause of anthurium yellow leaves, for example, if the water is too little and the fertilizer is too strong, the leaves of the plant will turn yellow, and the plant will remind us to do something to deal with it.

Watering too little to properly replenish water, watering every three days is good, fertilization should be in line with the principle of thin fertilizer diligent, you can mix the water-soluble fertilizer in water, along with the fertilization work.

It may be that the watering is relatively small, the temperature is too high, the sunlight is directly on the leaves, the soil is not rich in nutrients, and the soil is not good in air permeability and water absorption, so it will cause the anthurium leaves to turn yellow.

It may be that the method of maintaining it is wrong, watering should not be too much, not too little, the light should not be too dark, and the temperature should be moderate.

1.The temperature is relatively low.

The best growing 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 lower than 15 degrees, the anthurium will stop growing, and below 7 degrees, the leaves may be frostbitten. In addition, it is also necessary to avoid placing anthurium next to air conditioners or heaters, and not next to some radiators, otherwise it will cause anthurium yellow leaves.

2.Overwatering.

Yellow leaves This is one of the most common reasons for the yellowing of the leaves of the anthurium, the anthurium can keep the potting soil slightly moist in spring and summer, but it does not mean that the soil can be often moist, and the potting soil can not be waterlogged, too much water will lead to the lack of nutrients in the roots of the anthurium, which will lead to root rot, and the root rot is not visible, and the condition it shows is that the leaves continue to turn yellow. If the roots are rotten, the rotten part should be cut off in time, soaked in the sterilization solution, and transplanted with new potting soil.

3.Air dry.

This condition can also easily cause the leaves of the anthurium to turn yellow, because the anthurium itself grows in the rainforest and prefers a high humidity environment, and if the air is dry, it will cause the leaves to dry yellow. In this case, you must add some water to the anthurium in time, in addition, you can spray water around, which can increase the humidity of the environment, and you can also open a humidifier next to it, which can improve the environment well and avoid the red spider infection of the anthurium.

4.Nutrient insufficiency.

Cause the leaf yellow this situation is caused by the usual neglect of care, anthurium in the growth period slowly rise, but also occasionally supplement nutrients, especially after flowering, can be in spring, summer and autumn, once a month to supplement water-soluble fertilizer, you can also give some organic fertilizer water, to avoid giving too much thick fertilizer, do not fertilize too often, the concentration of fertilization is the usual 1 4, to avoid too thick fertilization caused by fertilizer injury, if you accidentally fertilize too much resulting in leaf yellow, you should timely rinse the pot soil with a large amount of water, Timely dilution of soil fertility.

5.The soil quality is too poor, and the anthurium itself has a relatively small demand for fertilizer, so it is not necessary to plant it with some particularly fertile soil, but at least it is necessary to ensure that there is appropriate humus in the soil, and the drainage of the potting soil should be good, so that these anthuriums can grow healthier and remain green all the time. If the potting soil is particularly poor, it is not supplemented with fertilizer for more than half a year, especially after flowering.

Every two years or so, you can change the potting soil to ensure that the soil is loose and breathable, the best soil for cultivating anthurium is to use some peat soil or humus, with some pine bark and perlite, and you can add some slow-acting organic granular fertilizer at the bottom.
