How to remedy the dry leaves of the iron tree? Can the iron tree survive when its leaves are yellow

If the plant is seriously deficient in iron, the leaves will also become dry or yellow, and the ferrous sulfate needs to be diluted and irrigated around the soil, and the iron trunk leaves may be caused by burns and poor ventilation, which need to be adjusted in time.

Causes of iron trunk leaves.

1. Improper moisture.

What is going on with the trunk leaves of the iron tree in the breeding process, it may be caused by excessive watering, the iron tree is not resistant to waterlogging, if it is too much watering every day, it is easy to appear yellow, so the daily watering can be in accordance with the principle of seeing dry and wet, and the growing season can be watered once every 2 3 days.

2. Iron deficiency. If the iron tree lacks iron, the leaves will also dry and turn soybeans, at this time, it is necessary to supplement ferrous sulfate, dilute it with water and water it around the soil, which can supplement iron for the plant and improve the yellowing and drying of the leaves. Usually, it can also be appropriately applied with water-soluble fertilizer to supplement nutrients.

3. Burns. Iron tree in the summer breeding is easy to appear leaf drying phenomenon, which is caused by leaf burns, need to timely shade and sun protection, appropriate spraying of water, improve air humidity, maintenance of a period of time iron tree leaves will gradually restore vitality.

4. Poor ventilation.

If the iron tree is closed indoors, the leaves will also become dry and yellow, which is caused by poor ventilation, at this time it can be placed outdoors with good ventilation, if the windows are often opened for ventilation, keep the smooth air, can improve the phenomenon of the iron tree leaves drying out.

The leaves of the iron tree are dry, and if they are not watered for a long time, the plants will dry up due to lack of water, so you need to water the plants to keep the soil moist. If the nutrients in the soil are not keeping up, then it needs to be fertilized immediately, either with a thin fertilizer.

It may be that it has not been watered for a long time and has dried up, so you need to water the plant to make the soil moist. If the nutrients in the soil can't keep up, then you need to fertilize it immediately, you can apply some thin fertilizer, you can't apply a lot of thick fertilizer in order to replenish nutrients as soon as possible, you should apply it gradually.

Iron TreeThe leaves are yellow, withered, and still alive.

Cut off the dead leaves and put them in a semi-shaded place to keep the soil moist and wait for the fifth lunar month.

New leaves will grow again. Iron tree is a iron-loving plant, and the culture soil is prepared.

When a small amount of iron filings can be infiltrated, or the iron filings are buried in the basin in early spring, the iron will gradually penetrate and be absorbed, and 05% ferrous sulfate.

Replenish iron to make the leaves firm and green. Repotting is carried out before budding in early spring, and generally after 2 to 3 years, the seedlings are slightly larger, and then they are planted in large pots.

The tree prefers warm and humid climates, loves sunlight, and is 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, lack of light.

As a result, the leaves are slender and the leaves turn green. If it is inconvenient to move outside, it should also be placed indoors in a window where light can be seen.

The growth environment of the iron tree:

Likes light, slightly tolerant of semi-shade. It likes warmth and is not very cold-tolerant, and when planted in the open field in Shanghai, warm measures such as straw bandaging are taken in winter. Prefers fertile, moist and slightly acidic soils, but can also tolerate drought. Plants that grow slowly and are more than 10 years old can flower.

Cycads grow slowly, have a lifespan of more than 200 years, and can extract a new round of leaves from the top of the stem every year.

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 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.

The remedies for yellowing and drying up the leaves of the iron tree are as follows:

1. The iron tree likes light, and needs sufficient light in the early stage of growth, otherwise it will cause the iron tree to yellow, wilt, and grow slowly, so it is necessary to cultivate the iron tree in a sunny place to ensure at least 6 hours of light a day, and if the leaf hardening occurs, the illumination can be appropriately reduced.

2. Correct watering In the growth period of new leaves of iron trees, it is necessary to replenish enough water, but do not let the potting soil be moist for a long time, otherwise the root system is prone to hypoxia, resulting in poor plant growth, and then yellowing of leaves. The lack of water can also cause the leaves to turn yellow, which is characterized by the yellowing of the leaves from the bottom up, and the old leaves turn yellow first, and if they are not watered in time, the leaves will turn yellow or even die.

3. Spraying insecticide pests is also one of the reasons for the yellowing of iron tree leaves, carefully observe whether there are red spiders, scale insects, etc. on the leaves, and spray pesticides in time to prevent them. When yellow spots appear on the leaves, carbendazim can be used to sterilize.

Iron tree meaning and symbolism

The origin of the iron tree is from central to southern China, Japan, India and Indonesia, and the more common varieties are South China cycads, Hainan cycads, Yunnan cycads, Taiwan cycads, grate cycads, Sichuan cycads and fork-leaf cycads.

The life span of the iron tree is very long, and it is generally possible to bloom after 10 years, so the iron tree has the meaning of longevity, perseverance, luck, wealth and auspiciousness and strength.
