Why do the leaves of the iron tree turn yellow?

Causes of yellowing of iron leaves:

1 The yellowing of some old leaves may be caused by uneven drying and wetting of the potting soil;

2. Due to the damage of scale insects, the damaged part of the leaves is yellow, and the diseased leaves should be cut off in time;

3. The whole plant is yellow, the potting soil is too dry or caused by serious diseases;

4 The use of raw fertilizer that is not well rotted or the application of too much fertilizer can also cause the roots to burn the leaves.

Iron Tree Planting Method:

First, the iron tree likes to be cultivated in acidic soil, and the fertilization can be applied with vanadium fertilizer water, or some rusty iron can be put in the soil, or the special fertilizer for the iron tree can be purchased in the flower market to use, which can make the iron tree leaves dark green and shiny, and improve the ornamental value.

Second, watering should be dry and wet. Iron trees like to be dry and avoid wet, and the potting soil is too wet for a long time, which will cause yellow leaves and rotten roots. In spring and summer, water once a morning and spray the leaves with a watering can to keep the leaves fresh and green. After autumn, it can be watered once in 3 to 5 days.

Third, the iron tree likes warm and humid climates, likes sunlight, and is also shade-tolerant. The growth is relatively slow, and the summer should avoid the scorching sun, otherwise it is easy to cause the phenomenon of scorched leaves and yellow leaves of iron trees. Iron trees should not be placed indoors for too long, as lack of light will cause weak leaves and loss of green.

It should be caused by the lack of fertilizer, and it is best to add organic fertilizer.

No, it grows a new round of leaves every year, and the old leaves turn yellow. In the south, two rounds of new leaves can be grown in a year, and only one round of new leaves can be grown in a year in the north.

1. Lack of sunlight.

The normal growth of iron trees is inseparable from sunlight, and if there is no sunlight, natural photosynthesis cannot be carried out smoothly, which will cause the leaves to lose green and yellow. Iron trees can be kept in a sunny place to maintain sufficient sunlight to promote the normal progress of photosynthesis and make the leaves green.

Second, the soil is unsuitable.

Iron trees prefer to grow in slightly acidic sandy soils, if the soil is alkaline or the soil is compacted and impermeable, it may cause poor growth and yellowing of leaves. It can be replaced with loose, breathable acidic soil, and if the soil is alkaline, it can be diluted with ferrous sulfate and watered.

3. Improper watering.

Improper watering can also cause yellowing of the leaves when growing and cultivating. Whether it's a lack of water, dry soil, or overwatering, stagnant water and stuffy roots can cause yellow leaves. If the watering is too little, you can immediately water to replenish the water to soak the soil, and if you water too much, you can control the watering so that the stagnant water in the soil is discharged.

Fourth, improper fertilization.

If the fertilizer is insufficient, it may lead to iron deficiency yellow leaves of iron trees. If the fertilizer is too much and too thick, it may accumulate fertilizer and cause root rot, which will cause yellow leaves. If it is determined that there is a lack of fertilizer, you can apply fertilizer in time to ensure good nutrients.

If you apply too much fertilizer, you should stop fertilizing and dilute it with watering.

5. Pests and diseases.

It is infected with pests and diseases that will cause yellow leaves, and it should be sprayed in time.

The yellowing of the leaves of the iron tree may be caused by a lack of light, so the iron tree can be moved to a bright environment for maintenance. It can also be caused by overwatering, so it is necessary to drain the water from the soil in time and transfer it to a ventilated environment for maintenance. It may also be caused by a lack of nutrients, so when maintaining iron trees, it is necessary to apply diluted liquid fertilizer every 1 week to supplement nutrients.

The reason why the iron tree turns yellow.

Iron trees are suitable for growing in a sunny environment, and need sufficient light during the growth period, and the lack of light will cause the iron tree to appear yellow, dry up, and slow down the growth rate. At this time, the iron tree needs to be moved to a bright place for maintenance, and given more than 6 hours of light, so that the iron tree can grow vigorously.

Iron trees are suitable for growing in humid environments, but they are less tolerant of waterlogging. When watering the iron tree daily, make sure that the soil is in a slightly moist state. Overwatering can easily produce stagnant water, which can lead to rot of the root system of iron trees.

The leaves will also turn yellow, so it is necessary to drain the water in the soil in time, and transfer the iron tree to a ventilated environment for maintenance, and in severe cases, it is necessary to repot.

Iron tree in the growth period of fertilizer demand is low, if not fertilized for a long time, will lead to iron tree leaves and rhizome lack of nutrients, and will appear yellowing, so in the breeding of iron tree, need to apply diluted liquid fertilizer every 1 week to supplement nutrition, so that the iron tree can grow vigorously.

Iron tree is suitable for growing in fertile and moist slightly acidic soil, if the soil is alkaline, it will cause iron tree to appear yellow, dry condition, at this time can be mixed into the soil to add an appropriate amount of ferrous sulfate solution to adjust the pH of the soil, so that the iron tree can resume growth as soon as possible.

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.
