What s going on with the yellowing of the leaves of the iron tree

The yellowing of the leaves may be in the process of maintenance, the water and fertilizer provided for it is excessive, and the water needs to be strictly controlled, or it may be that the iron tree receives insufficient light in the process of growth, and it needs to be supplemented with light, or it may be that the iron tree has a disease phenomenon, resulting in the contamination of the leaves by pathogens, resulting in the phenomenon of yellowing of the leaves.

The leaves of the iron tree are yellowing and can be cut off. Regardless of the cause of yellowing, the yellow leaves can be cut off, which can save a lot of nutrients and water, and can also avoid infection, which is beneficial to recovery.

However, if you want it to recover completely, you need to find out the cause of the yellow leaves and adjust the maintenance method. If there is a lack of light, more light should be added and moved to a astigmatism environment for maintenance. If the watering is not done properly, the watering method should be adjusted, and it is best to be moist during the growing season. If there is a lack of fertilizer, supplement it as soon as possible.

Causes yellowing of iron tree leaves:

1. Improper moisture.

The common cause of yellowing is water yellowing, because too much watering will cause the young leaves to turn yellow, and the iron tree is not tolerant to waterlogging. It is generally watered once every 2-3 days during the growing season.

2. Unbalanced nutrition.

There is also a kind of yellow leaf is a special yellow leaf produced by the lack of iron element in the plant, generally iron deficiency yellow leaves are new leaves are yellow, and the degree of old leaves is lighter. At this time, it is necessary to supplement some common iron supplementation reagents, such as ferrous sulfate, etc., and dilute it and pour it into the soil. In addition to iron deficiency, plants may also lack other nutrients, which can be supplemented in moderation.

3. Soil is alkaline.

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.

What is going on with the yellowing of the leaves of the iron tree is explained as follows:

The yellowing of the leaves of the iron tree may be due to the excessive amount of water and fertilizer provided for it in the process of maintenance, and the need to strictly control the water, or it may be that the iron tree receives insufficient light in the process of growth, and it needs to be supplemented with light, or it may be that the iron tree has a disease phenomenon, resulting in the contamination of the leaves by pathogens, resulting in the yellowing of the leaves.

Introduction to the Iron Tree Morphology:

The trunk is short, the base is swollen into a disc-like stem, the upper part is gradually narrowed into a cylindrical or ovate-cylindrical, 30 180 cm high, or slightly taller, 10 60 cm in diameter, the lower part is intermittent or branched. The pinnate leaves are 120 250 cm long, or longer, pubescent when young, and the leaf axis is semicircular, nearly round, or triangular in cross-section.

petioles 40 100 cm long, spines on both sides, spines slightly oblique downward, conical, about 3 mm long, straight or slightly curved, between spines in centimeters; Pinnately lobed lobes 40 120 pairs, or more, sparsely arranged in two rows on the leaf axis, the central pinnate lobes about 2 cm apart, lanceolate strips, straight or slightly curved, 25 33 cm long, cm wide.

Thin leathery, slightly thicker margins, slightly recurved downward, tapering at the top, apex tapering, base rounded, several symmetrical on both sides, often not extending downward, midrib raised on both sides, smooth and shiny, dark green above, lighter below.

Iron tree, rightly named cycad.

Yellow leaf causes: 1. Iron deficiency. If the leaves are yellowed due to iron deficiency, alum fertilizer water should be applied, or ferrous sulfate solution should be sprayed.

2. Burns. Summer shade protects from the scorching sun.

3. The soil is too wet. Soil that is too wet causes root rot and leaves turn yellow. Pay attention to watering not dry or watering, not long-term moisture.

4. There are too many leaves and too dense, and the ventilation is not good. You can cut off some of the leaves, and pay attention to the ventilation outside.

Yellowed leaves can be cut off. As long as the rhizome is not dead and a certain amount of ambient humidity is maintained, the iron tree will re-sprout new leaves.
