In winter, why do the leaves of indoor ornamental iron trees turn yellow? What can be remedied?

The yellowing of the leaves of the iron tree may be caused by the unsuitable pH of the soil, and the iron tree prefers weakly acidic soil. Plants need sufficient light to photosynthesize during the growth process, producing chlorophyll, and leaves will also turn yellow if there is not enough light. Cultivate iron trees to avoid excessive watering and stagnant water, and do not overdo it when fertilizing.

It is estimated that there is a lack of sunlight, and there may be insufficient air circulation in your home, in fact, the iron tree can be placed on the balcony, as long as it does not freeze, it is not afraid of cold.

Causes of yellowing of the new leaves of the iron tree:

1.Insufficient light, iron tree in the growth of new leaves must be maintained by the sun, only the leaves hardened and then placed in the semi-shade to appreciate, if there is no good light conditions during the growth period, it will not grow as expected.

2.Fertilizer is insufficient, nitrogen fertilizer is the main fertilizer when growing new leaves, fertilization is applied frequently, once every half month, it can be applied in holes, and liquid fertilizer can be used to irrigate the potting soil.

3.Soil alkalization, need to use ferrous sulfate solution 500 times to water the potting soil, once a week, several times in a row, can improve the color of the leaves.

4.Pests and diseases, pay attention to check whether there are insects on the leaves, such as red spiders, scale insects, etc. It can be eliminated by spraying air oil essence and laundry detergent solution. If the leaves have yellow spots and yellow spots, garlic liquid or carbendazim can be sprayed for sterilization.

5.The potting soil is too wet, although the iron tree needs a lot of water in the new leaf growth period, but it can not be wet for a long time, otherwise the root system is prone to hypoxia, resulting in poor growth, and the leaves are yellowed or rigid enough to bury a few iron nails in the pot Pay attention to prevent the compaction of the potting soil Loosen the soil on the surface Otherwise, how much water you water or how much fertilizer you apply is useless

When the leaves of the iron tree are yellow, the plant should be moved into the sunny place of ventilation for maintenance, and the plant should be kept in a ventilated sunny place every day, and the nutrients are insufficient, and a very dilute compound fertilizer aqueous solution should be released in a timely manner.

Iron tree is a sun-loving green plant, if the light given during the maintenance period is not enough, or the plant is placed in the shade for long-term maintenance, it will cause the leaves to become soft and yellow, so how to remedy the yellowing of the leaves of the iron tree, at this time, it is necessary to cut off the yellowing in time, move it into the ventilation of the sunny place for maintenance, and give enough sunlight every day, but the strong light should be moderately shaded.

Iron tree likes to grow and develop in the soil with abundant fertilizer, if the fertilizer is less at ordinary times, it will cause the plant to lack nutrients, and the leaves are very prone to yellowing.

Iron tree is a tropical rainforest plant, more suitable for warm conditions, if the temperature of the growing environment is very low, it is easy to produce frost damage, the leaves will slowly turn yellow and fall off, then the plant should be moved into the greenhouse for cultivation, when the temperature is less than 10 when covered with a layer of agricultural mulch, or manual heating treatment.

Iron trees need enough water during the growth period, but can not cause excessive wet and cold bonsai soil resulting in serious water storage, rhizomes will be inhaled and blocked, and the leaves will slowly turn yellow, at this time to stop watering, take out the rhizomes and cut off the root rot, pay attention to ventilation after re-cultivation, and watering to ensure that it is best to see dry and wet.

When the iron tree suffers from red spiders, bud worms, brown spot and other injuries, there will be many black patches on the leaves, and finally they will gradually turn yellow and burst out.

Alkalinized soil may be caused by high alkali content, which can cause yellowing of leaves. It can also be because of too much watering, too much watering can lead to a lack of oxygen in the roots. Too little watering and too much drought are also a cause of yellowing of the leaves.

The yellowing of the leaves may be due to a lack of nutrients in the soil, such as Zn, P, etc., or it may be suddenly too dry and have no water absorption. The remedy is that you can properly fertilize and water.

The yellowing of the leaves of the iron tree may be caused by the alkaline soil, and an appropriate amount of ferrous sulfate solution can be added to the soil to alleviate it. It may also be caused by a lack of light, in which case the iron tree can be moved to a bright place for maintenance. It can also be caused by overwatering, so stop watering and move the iron tree to a ventilated place for maintenance to speed up the evaporation of water.

The yellowing of iron leaves may be caused by soil discomfort. Iron trees are suitable for growing in a weakly acidic soil environment, if the soil of iron trees is alkaline, it is easy to make iron trees grow poorly, at this time, you can water an appropriate amount of diluted ferrous sulfate solution into the soil to alleviate it.

Iron tree needs sufficient light to synthesize chlorophyll during the growth process, if the iron tree is placed in a shady environment for a long time to maintain, it is easy to cause the iron tree to be unable to photosynthesize, and the leaves are yellow, at this time, the iron tree can be transferred to a bright place for maintenance, and the leaves of the iron tree can be restored to green after a period of time.

Iron trees are somewhat drought tolerant and require less water during their growth. If the soil is waterlogged due to overwatering during the farming process, it will cause the roots of the iron tree to rot, which in turn will cause the leaves to turn yellow. At this time, it is necessary to drain the stagnant water from the soil as soon as possible and transfer it to a ventilated place for maintenance to speed up the evaporation of water.

Iron tree in the growth process of the demand for nutrients is larger, in the fertilization of the iron tree, the fertilizer concentration should not be too large, so as not to burn the roots of the iron tree, resulting in the yellowing of the leaves, if the fertilization is too much, you need to water a lot of water in the pot, wash away the excess fertilizer in the soil, when the situation is serious, you need to change the soil again and then plant.

1. Iron deficiency will cause leaf yellow, and ferrous sulfate can be sprayed to treat iron deficiency according to the time of use.

2. Caused by over-watering, it is characterized by no obvious change in the old leaves and yellowing of the young leaves; Water should be controlled immediately.

3. Due to lack of water and drought, it is characterized by the first yellow leaves from the bottom up, if the lack of plum file water for a little longer, the whole plant will be yellow leaves, and even die, so it should be watered in time.

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

5. Noise 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 a time, so as not to cause root burning.

6. For leaf yellow caused by diseases, such as leaf blight, you can use Duoyinling or Tobuzin to spray the whole plant according to the instructions for use or the usage taught by the boss.

1.Plants lack nitrogen, the old leaves first begin to turn yellow, and then gradually turn yellow from the bottom up, timely supplement urea, ammonium bicarbonate, ammonium sulfate and other nitrogen fertilizers from the roots or leaves, or import high-nitrogen water-soluble fertilizers, you can promote the leaves to turn green.

2.Crops lack phosphorus, the whole plant will turn dark green, and no luster, the leaves will also turn yellow, timely supplement of superphosphate and other phosphorus fertilizers, can promote the leaf to restore luster.

3.Crops, fruit trees, vegetables and flowers are deficient in potassium, the leaves will be uneven, and the edges of the leaves may also turn yellow and withered.

4.Plant iron deficiency, young leaves and old leaves at the same time yellowing, young leaves of the mesophyll yellow, leaf veins green, the formation of a network of yellow leaves, generally watered ferrous sulfate, but the concentration should not be too large, can be applied in stages, to avoid burning roots.

5.Crops lack calcium, young leaves turn yellow and curl, can be applied to crushed egg shells or Ribery Yanwo imported chelated calcium and magnesium fertilizer to reduce the harm.

6.Plants are deficient in magnesium, the leaves turn green and yellow, and finally dry up and die, and calcium, magnesium, phosphorus, and magnesium sulfate fertilizers are applied in time.

7.Crops are deficient in sulfur, leaf veins are yellow, and ammonium sulfate is applied in time to promote the leaves to turn green.

8.In strong alkaline soils, yellowing of leaves will also occur, and acidic fertilizers such as rice washing water and ferrous sulfate can be applied to change the soil environment.

9.Overwatering or stagnant water, the young leaves of the plant turn yellow, excessive drought, the old leaves begin to turn yellow, gradually aggravated from the bottom up, and even the whole plant dies, adjusting the soil moisture can be effectively remedied.

10.Too much fertilization or too short interval time will cause fertilizer damage, and the young leaves will be uneven, but the leaves are thick and shiny, and the symptoms can be alleviated by controlling fertilizer watering and cultivating loose soil.

There are several reasons why the leaves of the iron tree turn yellow. Water yellow is a common plant disease, mainly because of too much watering, resulting in the young leaves turning yellow, the old leaves have no obvious characteristics, because the amount of water is immediately controlled to ensure its normal absorption.

Fat yellow, the main reason is because of too much fertilization, the concentration is too high, the main manifestation is that the young leaves are hypertrophied, shiny, and uneven, should control the fertilization, control its water amount, to ensure that its nutrition is normal.

Hungry yellow, on the contrary to the above, because the fertilization is not enough, the concentration is too low, or the fertilization interval is too long, its manifestation is the young leaves, young stems at the first yellow, if not immediately fertilized will lead to the death of flowers, the lack of fertilizer flowers, can not be over-fertilized, so as not to cause root burning.

Drought yellow, because of insufficient watering, drought, its manifestation is from the bottom up of the old leaves first yellow, if the lack of water for too long, will lead to the whole plant leaves yellow, and even death, should be watered in time to ensure its water volume.

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.

Iron tree is a relatively light-loving plant, especially in the early stage of growth, there is less sunlight in winter, 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. It should be moved to a well-lit place, and it is best to maintain it with full light at the beginning of growth, with at least six hours of light per day. If the leaves have hardened, they can be cured in the form of half-day.

The most common reason for the yellowing of the leaves of the iron tree is that it is overwatered, although it likes to be moist, but once the water accumulates, it is easy to cause the root system to rot, and the leaves will turn yellow. Move the potted plants to a well-ventilated place in time to allow the water to evaporate as soon as possible. If the situation is more serious, it should be removed from the pot to dry, and the soil should be replanted after drying.

In the later stage of watering, it is necessary to see dry and wet, and the low temperature in autumn and winter should be controlled.

Iron tree leaves do not need much fertilizer to grow, but that doesn't mean you don't need to fertilize them. If you don't fertilize for a long time, the young leaves and stems will turn yellow, and eventually spread to the whole plant to turn yellow, affecting the ornamentation, and even possibly dying. If the above situation is very easy to solve, only need to properly supplement the water-soluble fertilizer of Fate's amino acids.

However, it should be noted that you should not use excessive or high concentration of fertilizer at one time, otherwise it will burn the roots, and you can apply thin fertilizer frequently.

<> the leaves of the iron tree are yellow in winter, you need to use sharp scissors to cut off the yellowed leaves of the plant, after pruning, you can spray disinfectant on the wound of the iron tree, and put it indoors, and then control the temperature of the environment at about 20 degrees, create a warm environment for the iron tree, and promote the plant to recover as soon as possible.

1. Prune.

Iron trees have yellow leaves in winter and need to be pruned, you can use sharp and disinfectant scissors to cut off the yellowed leaves of the plant, and then spray the iron tree with disinfectant or carbendazim to avoid bacterial infection in the wounds of the plants.

2. Maintenance management.

After the iron tree is pruned, the temperature of the environment can be controlled at about 20 degrees to create a warm and suitable environment for the plant, and then the iron tree is applied with a well-rotted liquid fertilizer every 1-2 weeks to supplement the nutrients for the plant, so that the iron tree can recover as soon as possible.

3. Provide moisture.

When breeding iron trees in winter, it is necessary to reduce the water content of the plant, because the iron hole is afraid of waterlogging, if the soil is waterlogged, it will lead to rotten roots, you can water the iron tree every 10-14 days to keep the soil slightly moist.

4. Illumination strip pick-up judgment.

In winter, it is best to maintain the iron tree in the sun at noon when the light is relatively bright, so that the plant can receive natural light throughout the day for photosynthesis and avoid the phenomenon of wilting of the iron tree.
