The leaves of the iron tree are yellow, what should I do?

Iron trees have strong adaptability, strong nature, relatively few pests and diseases, and extensive management. Yellowing at the base of your iron tree leaves may be related to management. Iron tree is a sun-loving plant, and it is best to place it in an environment with sufficient light and can tolerate a semi-shady environment, but it should not be placed in the shade for a long time.

Watering is best to alternate dry and wet, potting soil is not dry, do not water, be sure to water thoroughly when watering. When the temperature is high in summer, it is required to water more frequently, and if the temperature is lower than 15 in winter, it is necessary to maintain a certain dry state, and it can be watered thoroughly when it is dry. Iron tree fertilization mostly starts in spring when the temperature rises, and nitrogen fertilizer is mainly used to meet the demand.

Try not to fertilize during the high temperature in summer and the low temperature in winter. It is best to add some phosphorus and potassium fertilizer in autumn to improve antibodies and facilitate overwintering. In addition, most of the leaves of the iron tree only retain the annual leaves, and all the old leaves are cut off, and the leaves will not be beautiful after many years.

Note that sufficient light conditions are required during the new leaf growth period (mostly in May and July every year), and fertilizer and water should also keep up. If the light is insufficient, the leaves will grow and become long and thin, losing their due ornamental value. If there is only a small part of the yellow on the leaves, you can cut off the yellow leaves, and then cut them all when the new leaves grow after the temperature rises next year.

1. Insufficient light causes yellowing of leaves.

In the process of growing, plants need sufficient sunlight for photosynthesis, which produces the nutrients that the plants themselves need. If you put the iron tree indoors in a dark place, the leaves will turn yellow due to insufficient light. Therefore, it is necessary to move the iron tree to the balcony where the light can be seen in time, and adjust the orientation of the plant in time during the maintenance process, so that the plant will not grow in the sunny direction due to uneven light.

2. Improper watering causes yellowing of leaves.

The iron tree prefers a warm and moist growing environment, and although it likes to be moist when it is slippery in hail, it is not tolerant of waterlogging. When some flower friends water it, they water it too often, resulting in water accumulation in the roots, causing root rot, and then yellowing of the leaves, and another reason is the lack of water, which will also cause its leaves to turn yellow. The best way is to use the watering principle of seeing dry and wet, observe that the surface of the potting soil is dry, and there are signs of whitening, and water it thoroughly at one time, but there should be no stagnant water at the roots, and then put it in a ventilated environment for maintenance.

3. Improper fertilization causes yellowing of leaves.

Iron tree is a perennial plant, it will continue to absorb nutrients in the soil in the process of growth, so a long time will cause its soil nutrients to be insufficient, at this time, it is necessary to fertilize it in time, but when fertilizing, remember to apply thin fertilizer frequently, do not apply thick fertilizer, thick fertilizer will also cause the phenomenon of burning roots and yellow leaves.

1. The yellowing of the leaves of the iron tree is caused by a variety of reasons, among which the yellowing is one of the most common reasons, the so-called yellowing is too much watering for the iron tree, the most obvious manifestation is that the old leaves of the iron tree do not have the symptoms of yellowing, but the young leaves are all yellow, at this time, as long as the amount of watering is controlled in time, the yellowed leaves can be turned back to green.

2. Lack of water is also an important reason for the yellowing of the leaves of the iron tree, because of the lack of water to make the leaves of the iron tree yellow, it will start to change color from the old leaves of the iron tree, if the lack of water is too often, all the leaves will turn yellow. If you don't water it in time, the iron tree will eventually die due to lack of water, and the best remedy is to water the iron tree quietly.

3. Excessive or too little fertilization is also an important reason for the yellowing of iron leaves, when the amount of fertilizer is too much, its young leaves will become EF and the symptoms of unevenness, this shed should be rented in time to control fertilizer and watering and cultivating, only in this way can the excess fertilizer be precipitated to make the iron leaves green again. When there is a shortage of fertilizer, the young leaves of the iron tree will also turn yellow, and as long as the top dressing is in time, the color of the leaves can be changed.

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.

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.

Reason: It 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 slow down.

Solution: 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 time per day. If the leaves have hardened, they can be cured in the form of half-day.

Reason: The more common reason for its leaves to turn yellow is that they are overwatered, although they like to be moist, but once the water is accumulated, it is easy to cause the root system to rot, and the leaves will turn yellow.

Solution: 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.

Reason: It doesn't need much fertilizer to grow, but that doesn't mean it doesn't need to be fertilized. 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.

Solution: If the above situation is very easy to solve, just need to properly fertilize. 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.
