Green leaves, why do their leaves turn yellow? what's the reason?

The main results are as follows: 1. too much watering, the basin soil is too wet for a long time, resulting in lack of oxygen in the soil, causing some fibrous roots to rot, hindering normal respiration and absorption of water and nutrients, causing leaves to turn yellow and fall off. After the injury, the young leaves turn pale yellow, and then the old leaves gradually turn yellow. watering should be controlled immediately, fertilization should be suspended, and the soil should be often loosened to make the soil well ventilated.

2. First of all, it may be due to excessive watering leading to long-term waterlogging of the soil, resulting in lack of oxygen in the roots and yellowing of leaves. Secondly, it may be due to the long-term lack of water in the roots of green-leaf plants, resulting in yellowing of leaves.

It turns out that there are many natural pigments in the leaves of plants, such as chlorophyll, lutein, anthocyanins and carotene. The color of the leaves is caused by the content and proportion of these pigments.

4. There are many reasons for the yellowing of green pineapple leaves, such as improper watering, unbalanced light and improper fertilization. After the discovery, cut off the yellowed leaves in time, and then trim half of the new buds, and control the amount of water in the maintenance process, give it appropriate sunlight, and fertilize reasonably.

5. Due to the long-term lack of sunlight, the leaves do not have enough light, and the plants cannot form chlorophyll, which leads to the yellowing of the leaves. We just need to move the plants to the place where the sun shines directly. To sum up, there are certain reasons for the yellowing of plant leaves. It is necessary to find the right medicine for the disease, so that more luxuriant plants can be planted.

What if the leaves of Phalaenopsis turn yellow?

The light is too strong. The yellowing of the leaves is likely to be caused by excessive light. Solution: cut off the yellow leaves in time, and then cover the strong light for the plant to ensure that it has the right amount of scattered light, so that it can return to normal. The temperature is uncomfortable.

First, the light is too strong, sunburn leaves will be exposed for a long time, to reduce the exposure time, reduce the light intensity, will slowly recover. Second, the lack of moisture, it likes the humid environment, the environment or soil is too dry, it is easy to have drought and yellow, to replenish water.

When it is found that the leaves of Phalaenopsis are yellow, first take off the yellow leaves, and then check whether the water moss of Phalaenopsis has rotted, and if there is any decay, update it.

The reason and treatment method for the yellowing of Phalaenopsis leaves are: the light is strong: Phalaenopsis likes to grow in semi-shady astigmatism and cannot stand strong light. If it is accidentally exposed to strong light, it may cause sunburn and yellowing of the leaves.

Strong light exposure is suitable for Phalaenopsis to grow in a semi-shady astigmatism environment. If it is kept in a sunny environment for a long time, the leaves will wither and yellowing after being exposed to strong light. When the situation is serious, the whole plant will die.

The cause of yellowing of green apple leaves and its solution

1. Lack of light: green pineapple needs the right amount of light for photosynthesis. If there is not enough light, the leaves will turn yellow. The solution is to put the green pineapple where there is scattered light to avoid direct sunlight. Too much or too little watering: green pineapple likes a wet environment, but too much watering may cause root asphyxiation, and too little watering can lead to lack of water in the leaves.

2. Green pineapple likes a slightly cool environment and is not resistant to the sun. If you are exposed to direct light for a long time during culture, the leaves will be sunburned if the light is too strong, resulting in yellow leaves. If it is caused by this situation, it is necessary to shade the light as soon as possible, move the green pineapple to a semi-overcast, well-ventilated environment, and spray water around frequently, so that it will slowly recover.

3. Lack of moisture and withering at the edge of the leaf. If there is not enough water in the green apple soil, it will cause the leaves to become withered and yellow, and the leaves will fall off. Therefore, it is necessary to pour enough water on the green apple at this time. If there is too much water, the leaves will be dark yellow.

4, improper lighting: green pineapple generally grows in a cool environment, if you put it in the strong sun for a long time, it will easily lead to leaf shrinkage, and then yellowing and falling off. However, putting it in a cold and closed environment is not good for the growth of green pineapple, the green leaves will lack chlorophyll and the color will turn yellow.

What is the reason why the leaves turn yellow?

The old leaves are normal and the young leaves are yellow and dry, usually due to the lack of some key nutrients or diseases. Here are the possible reasons: nitrogen deficiency: plants need a lot of nitrogen to grow. If there is not enough nitrogen in the soil, it will make the young leaves yellow and dry.

Lack of light: green pineapple needs the right amount of light for photosynthesis. If there is not enough light, the leaves will turn yellow. The solution is to put the green pineapple where there is scattered light to avoid direct sunlight. Too much or too little watering: green pineapple likes a wet environment, but too much watering may cause root asphyxiation, and too little watering can lead to lack of water in the leaves.

The reasons for the yellowing of leaves are: lack of light, lack of nitrogen fertilizer, lack of phosphorus fertilizer, lack of potassium fertilizer, lack of iron and other factors. Lack of light if the plant does not see light for a long time, then the leaves of the whole plant will turn yellow, weak and fall off. Solution: put the plants in a sunny place until they are restored.

Why do the leaves turn yellow?

The tender leaves on the top of too many flowers are yellowish, the old leaves are gradually yellowing, and the new shoots are shrinking. This is due to long rain or too much watering, too wet in the basin, lack of oxygen in the soil, and root rot. The soil should be loosened often, watering should be controlled and heavy rain should be avoided.

The temperature is not right. If the room temperature is too low in winter, if the evergreen flowers and trees introduced from the south are slightly frozen, the leaves will turn yellow. If the room temperature is too high, the plant transpiration is too high, and the root water and nutrients are insufficient, the leaves will turn yellow. The room temperature should be adjusted in time according to the situation. 1 damage caused by diseases and insects.

Lack of light: green pineapple needs the right amount of light for photosynthesis. If there is not enough light, the leaves will turn yellow. The solution is to put the green pineapple where there is scattered light to avoid direct sunlight. Too much or too little watering: green pineapple likes a wet environment, but too much watering may cause root asphyxiation, and too little watering can lead to lack of water in the leaves.

The temperature is not right. If the room temperature is too low in winter, the flowers are often vulnerable to cold damage, which leads to the yellowing of the leaves and death in severe cases. If the room temperature is too high, the transpiration of the plant is too high, and the root water and nutrients are in short supply, the leaves will turn yellow. Please pay attention to adjust the room temperature in time. (11) the soil is sour.

The sunshine time in autumn gradually shortens, and the temperature drops with it, and the decrease in light weakens the photosynthesis of leaves, so leaves produce very little chlorophyll under photosynthesis, and nutrients will be transported through branches to tree trunks and roots for storage in preparation for the winter.

In autumn, because the temperature is low and the air is dry, the soil water is lost, and the leaves will fall, giving nutrients to the plants, allowing trees to survive on a small amount of nutrients.
