Causes of whitish leaves of the iron tree How to remedy it

1. Lack of sunlight.

Reason: Under the exposure of sunlight, the chlorophyll in the leaves of the iron tree can play a role, making the leaves green and shiny. If it is kept in a low-light place for a long time, it is not exposed to sunlight, and photosynthesis cannot be carried out, which may cause the leaves to turn white.

Solution: The normal growth period should be kept in a well-lit place, if there is a lack of sunlight, you can gradually increase the sunlight, and you must not move directly to strong sunlight.

Second, the soil is alkaline.

Reason: Soil is the basic factor of growth, if the soil in the growing environment has been alkaline, so that the plant can not adapt, hinder normal growth, and will also cause the leaves to turn white.

Solution: You can put a little acidic substance into the soil, such as vinegar, or directly replace it with new acidic soil.

Iron trees have white spots on their leaves, and there is a high possibility of encountering pests and diseases, and scale insects are common. Scale insects are insects that feed on the leaf tissues of iron trees with their stinging and sucking mouthparts, which not only plunder a large amount of plant sap, destroy the leaf tissues, and cause tissue discoloration and death.

The remediation depends on whether it is a germ or a pest. It is a bacterium that can be purchased for fungicide use, if it is a white worm, you press to see if there is red blood, if there is, it may be an ash scale, and now the main drug is snail ethyl ester.

1.Auxiliary lighting:

Reason: This is a relatively light-loving plant, especially in the early stage of growth, if the light is insufficient, it is easy to cause new leaves to turn yellow, dry up, and the growth rate will be slowed down.

Treatment: It should be moved to a place with good light, and it is best to carry out all-light maintenance in the early stage of growth, with no less than 6 hours of light a day. If the leaves have hardened, they can be maintained in a half-sun way.

2.Overwatering:

The leaves of the iron tree turn yellow and dry out, probably due to overwatering, which has formed a large amount of standing water in the soil. Iron trees like moisture, but can not tolerate moisture, watering to the right amount, once watered too much, will cause the roots to breathe, the appearance of rotten roots, resulting in yellow, dry leaves.

Countermeasures: In daily life, the watering of iron trees should insist on seeing dry and wet, once there is too much water, stop watering in time, maintain ventilation, and promote water evaporation. If the water is very serious, the iron tree can be taken out of the original pot and directly changed the pot and soil.

3.Proper fertilization:

Causes: If the iron tree is not fertilized enough for a long time, it will cause nutrient deficiency, such as the lack of iron stress tolerance elements, the leaves will turn yellow and dry.

Countermeasures: In the usual growth period, it is necessary to insist on thin fertilizer and frequent application, supplement the nutrients needed for growth, and supplement accordingly after determining the lack of certain nutrients.

There can be a variety of causes of bleaching of iron tree leaves, and here are some possible causes and solutions:

1.Lack of light: Iron trees need plenty of bright indirect light to maintain the bright green color of their leaves. If the tree does not receive enough light, the leaves may turn white. Move the plant to a location with better light and make sure it receives the right amount of sunlight.

2.Lack of nutrients: Iron trees may lack certain nutrients from the state, causing the leaves to turn white. This can be due to a lack of nutrients in the soil or overwatering leading to nutrient erosion. Apply fertilizer at the right time and make sure to water it correctly according to the needs of your plants.

3.Excessive sun exposure: Iron trees are sensitive to strong sunlight radiation. Excessive sun exposure may cause the leaves to turn white. Move plants to a location that is protected from direct sunlight and provide proper shade.

4.Pest and disease problems: Certain pests and diseases, such as aphids, powdery mildew, etc., may affect the leaf health of iron trees, causing them to turn white. Check if the plant is infested with pests and diseases, and if so, treat it with appropriate control measures.

5.Ambient temperature is too high: Iron trees are sensitive to high temperatures and dry environments. If the ambient temperature is too high or the air is too dry, it can cause the leaves to turn white. Make sure that the environment in which the plants grow is at the right temperature and that proper humidity is provided.

For specific reasons, you can carefully observe the growth environment and leaf changes of the iron tree, and then take corresponding measures to deal with the problem. If the problem persists or the cause cannot be identified, it is best to consult a professional horticulturist or plant pathologist for more specific help and advice.

Reason: The leaves of the iron tree are likely to turn yellow with too much watering, although it likes a moist growth environment, but it is more afraid of waterlogging, and too much water will cause root rot, and the leaves will turn yellow.

Treatment: At this time, it is necessary to water sparingly, and the principle of seeing dry and wet should be maintained, and the cultivation soil must be dried before watering, and the leaves will turn green after a period of water control.

Reason: Its demand for nutrients is very low, but it also needs to be fertilized properly, and if you don't fertilize for a long time, it will cause the leaves to turn yellow due to lack of nutrients.

Treatment method: Supplement some fertilizer for the plant as soon as possible, but not a large amount of fertilizer at one time, otherwise there will be a situation of burning roots, and fertilizer should be gradually increased.

Reason: The plant is suitable for growing in sunny and warm places, especially during its growing season, when the leaves will turn yellow if they do not see sunlight for a long time.

Solution: Immediately move the bonsai to a sunny place to receive as much light as possible, but shade should be taken in the hot summer.

Summary. Pro, apply nitrogen, phosphorus and potassium compound fertilizer every half month during the growth period of iron trees, and supplement phosphorus, potassium fertilizer and iron fertilizer in an appropriate amount. To promote the dark green and shiny color of iron leaves, an appropriate ferrous sulfate solution can be added to the fertilizer.

Note that the concentration of fertilizer should not be too high each time, and dilute it with water before fertilizing.

In order to make the leaves of the iron tree green, it is necessary to maintain sufficient light first, which is conducive to photosynthesis and allows the branches and leaves to grow luxuriantly. When the sun is too strong in summer, it should be placed in a cool and ventilated place to avoid dry leaves caused by sun exposure.

What happened to the iron tree's leaves turning gray and then drying.

Hello, too much watering of the iron tree will cause dry leaves, so every watering should be done in the principle of rather dry than wet. Too much or too little fertilizer can easily cause dry leaves, so it is necessary to apply regular and quantitative fertilizer during the growth period, mainly with Yousong nitrogen, phosphorus and potassium compound fertilizer Qingkai. Long-term lack of light or direct sunlight will lead to dry leaves.

Therefore, it is necessary to get enough sunlight every day and avoid sun exposure.

Dear, the properties of the iron tree are not moisture and drought tolerant, and if you water too much, it will lead to dry leaves. Therefore, in the process of watering the iron tree, you should not be overly diligent in the canopy, and if you plant it outdoors, you can do it without watering and picking, and if you do it indoors, you can do the principle of dry rather than wet. It is best to do each watering on a sunny day and spray the foliar water appropriately.

Pro, apply nitrogen, phosphorus and potassium compound fertilizer every half month during the growth period of iron trees, and supplement phosphorus, potassium fertilizer and iron fertilizer in an appropriate amount. To promote the dark green and shiny color of iron leaves, an appropriate ferrous sulfate solution can be added to the fertilizer. Note that the concentration of fertilizer should not be too high each time, and dilute it with water before fertilizing.

In order to make the leaves of the iron tree green, first of all, it is necessary to maintain sufficient light, which can facilitate photosynthesis and make the branches and leaves grow luxuriantly. When the light is too strong in summer, it should be placed in a cool and ventilated position, so as to avoid the phenomenon of dry attack on the tomb leaves caused by exposure to the sun.

1. Too little watering.

One of the most common causes is too little watering, as too much water will cause the new leaves to not absorb enough water, resulting in a large number of new leaves turning yellow. At this time, the yellowed and wilted leaves need to be pruned off, choose reasonable watering to solve this problem, it is best to choose watering once a day in the morning to ensure that the soil is moist. The time will improve after a week.

2. Overwatering.

Overwatering can also cause the leaves to turn yellow, which is caused by stagnant water. Often, the roots will rot to a certain extent. This one is more troublesome.

It is necessary to dig out a part of the soil appropriately, choose to fill it with dry soil, so as to absorb a certain amount of water, and put some desiccant in the special area appropriately, so as to reduce the moisture. This recovery will take a little longer, usually a month to slowly regain growth.

3. The soil is alkaline.

If the cultivation period is not properly maintained, the soil will be alkaline, and the iron tree needs to be cultivated in slightly acidic soil. Therefore, it is not difficult to improve the acidity and alkalinity. Choose to use ferrous sulfate solution 500 times liquid watering, generally once a week, after a month basically the soil will be slightly acidic.

You can use a test strip to measure it.

4. Too much fertilization.

Excessive fertilization is not a good thing for many plants, which will lead to root burning. Iron trees are no exception, and if you fertilize too much, they will burn their roots. This one is also tricky.

Some soil needs to be dug out properly so that the soil fertility does not continue to be as high. Proper watering to dilute the filled soil can be poor, so that the fertility will not be so high at all. Gradually, the leaves will not continue to turn yellow.

5. Insufficient fertility.

If you don't fertilize for a long time, it will also cause special leaves to turn yellow, which is caused by insufficient fertility. In particular, if the soil is compacted, it is more likely to cause the leaves to turn yellow. Proper loosening of the soil is required, followed by fertilization, preferably with a diluted fertilizer, which avoids too high fertility.

You can do a small amount of fertilizer once a week to improve it, and then you can apply fertilizer on time at regular intervals.

6. Insufficient light.

The Iron Tree has a need for light. If there is not enough light, the leaves will turn yellow. Therefore, it is necessary to ensure sufficient light, because the leaves are yellowed due to the lack of sunlight for a long time, and the iron tree at this time is actually relatively fragile.

You can start by properly irradiating the morning sunlight to improve, and when there is some improvement, gradually extend the irradiation time to improve thoroughly. In the later stage of maintenance, ensure proper sunlight.

7. Normal old leaves.

After the iron tree grows to a certain stage, there will be some old leaves yellow, which writes the old yellow leaves, choose to prune them off, so as to promote the growth of new leaves, after pruning, you can properly irradiate a certain amount of sunlight, so that the pruned wound can better heal and grow. It is important to note that after pruning, do not water the trimmed part.

There are many reasons for the yellowing of iron leaves, if the soil is alkaline, it can be watered with ferrous sulfate solution; If it is caused by unsuitable light, it needs to be repaired and shaded in time; If it is caused by unsuitable watering, it is necessary to ensure that it is watered once in the morning and evening in summer, and once in 10 days in winter; If it is caused by improper use of fertilizer, it needs to be fertilized scientifically and thinly applied frequently.

1. Acidic solution.

Reason: The growth of the iron slag tree requires a slightly acidic environment, and if the soil is alkaline, it will cause the leaves of the plant to turn yellow.

Solution: You can choose to water and spray weak acidic substances such as 500 times ferrous sulfate aqueous solution, once a week, and after watering several times, you can gradually see the effect.

2. Sufficient light.

Lack of light will lead to insufficient nutrients during the growth period, and the leaves will shrivel and turn yellow.

Solution: When the sun is shining, irradiate the plant under scattered light, and do not grow in semi-shade or full shade all the time.

3. Proper watering.

Reason: Too much or not enough watering can lead to yellowing of leaves, if too much watering, it will lead to hypoxic rot of the root system, stiffening and yellowing caused by poor growth; If the hypothesis is not enough, the plant will turn yellow from the bottom up, from old to new, due to lack of water.

Solution: The amount of water should be controlled when watering, and the lack of water in summer should be once in the morning and evening, and once in about 10 days in winter.

4. Scientific fertilization.

Causes: Applying too much or too little fertilizer can cause yellowing of the leaves.

Solution: When fertilizing, the concentration should be lower, and the thin fertilizer should be applied more, if the concentration is too high or the fertilization is too frequent, then the fertilizer should be controlled and watered in time; If the number of fertilization is small, when the young leaves begin to turn yellow, pay attention to fertilizer, but do not apply thick fertilizer.

5. Prevention and control of pests and diseases.

Causes: Pests and diseases such as spider mites, scale insects, yellow spots and yellow spots on leaves can also cause yellowing of the leaves of the plant.

Solution: Remove the diseased leaves, and then spray them in time with carbendazim and other agents to sterilize.
