What to do when the leaves turn yellow in the face of good luck? 7 reasons and treatment methods

What to do when the leaves turn yellow? 1. Change the soil

There are more saline-alkali in basin soil, and the leaves of Hongyun will gradually lose green and turn yellow.

How to deal with it?

In family cultivation, peat soil can be mixed with 2 parts of peat soil and 1 part of fine sand to prepare culture soil. Generally, the soil bought from the flower market is suitable for plant growth. When you add soil to it later, you should pay attention to the soil quality.

2. Control the accumulation of water

At the head of good luck, the soil has been too wet for a long time, even stagnant water, causing some fibrous roots to rot. At the head of good luck, the new leaves turn yellow, while the old ones are normal.

How to deal with it?

Drain the stagnant water from the basin in time. If Hongyun is in an environment where the soil is too wet for a long time, the plant can be removed from the pot and the soil can be dried and replanted. After normal watering, the leaves will gradually return to green.

3. Increase sufficient light

The location has been short of sunshine for a long time, so the old and new leaves will also turn yellow.

How to deal with it?

Put good luck on the balcony or windowsill where there is plenty of sunshine, appropriate, gradually increase the light.

4. The temperature of culture environment is stable.

In winter or summer, move the plant indoors near the doors and windows, and between the doors, the leaves turn yellow.

If the indoor temperature is too low in winter, 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.

How to deal with it?

The highest temperature can not be higher than 30 ℃, high temperature is disadvantageous to its growth, and its growth slows down. However, if the temperature is kept at 10 ℃ for a long time, the leaves or bracts will turn red and white. Yellowing occurs because the temperature is too low, antifreeze can be sprayed, and the temperature can be raised appropriately. If the temperature is too high, ventilation and cooling in time, it will be gradually improved.

5. Increase environmental humidity

The air is too dry due to insufficient humidity. The leaf tip is dry and yellowing, or the leaf edge is scorched, or the leaf has scorched spots, edge curling and other phenomena.

How to deal with it?

According to the growing season, properly increase the air humidity and often spray water to the leaves and the surrounding environment. Keep the plant away from the air outlet of heating and air conditioning as far as possible in winter.

6. Move to an environment free of pollution

At the head of good luck, it was attacked by external smoke, poison gas, or radiation, and the old leaves and new leaves turned yellow gradually.

How to deal with it?

Hongyun does not absorb radiation at first. If you put the plant next to the air conditioner or the TV set, too much radiation will cause the leaves to turn yellow. Remind flower friends not to put good luck in these places. If you put it now, you should move it to a hollow and fresh balcony or other well-ventilated location as soon as possible.

Cut off the yellowing leaves

The growth of new leaves at the head of Hong Yun, or the gradual yellowing and wilting of leaves after flowering is a normal metabolic phenomenon. Occasionally the leaves turn yellow, the other leaves are fresh and tender yellowish green, and the flowers grow well.

How to deal with it?

Just cut off the withered and yellow leaves to ensure daily maintenance.

8. Pest disease control

In the environment where the temperature or humidity is too high and the ventilation is poor, diseases and insect pests are easy to occur. In good luck, the leaves show signs of yellowing or curling.

How to deal with it?

Chemical control and strengthen cultivation management, should be often ventilated and transparent, watering should be appropriate, a good degree can be controlled, a small amount of water can be added to the blade tube, and it can be used as a supplement when watering too little.

8. Supplement adequate nutrition an and appropriate amount of nitrogen fertilizer

Symptom 1: the basic leaves are aging and falling off, the plants are uniform light green to yellowish green, and the leaves become smaller.

B, appropriate supplement of phosphate fertilizer

Symptom 2: the leaf margin of the old leaf at the base is yellow, the petiole is purplish red, the leaf is hard and smaller, and the plant is short.

C. Supplement potash fertilizer appropriately.

Symptom 3: yellow between the veins of the old leaves at the base, while the young leaves of the plant are small and the leaves are light green or red.

D, appropriate amount of calcium fertilizer supplement

Symptom 4: the tip of the tender leaf turns yellow and hooks, and then dies inward from the leaf tip and leaf edge, and in severe cases, the stem top fester and necrosis.

E, appropriate amount of magnesium fertilizer

Symptom 5: the old leaves turn yellow along the veins, and the veins remain green.

F, appropriate amount of sulfur fertilizer supplement

Symptom 6: the veins of the apical tender leaves are yellowish green and the leaves are red or purple.

G, supplement appropriate amount of iron fertilizer

Symptom 7: the old leaves are green, the new leaves turn yellow, but the veins remain green, and the leaves become more and more yellow.

Stop fertilizing and increase watering

Symptoms: excessive fertilization showed dry tip and scorched yellow shedding of old leaves, and thick and uneven new leaves.

What if the leaves turn yellow and curl (causes and solutions) when good luck is rotten?

When it comes to good luck, everyone must be very familiar with it, because there are many people who grow good luck in their shops, companies or homes, not only because it has a very beautiful appearance, but also because its name sounds particularly auspicious. has an excellent moral. However, some flower friends responded that the good luck of breeding for a period of time led to the phenomenon of yellow and curly leaves, which was very ugly. How to deal with it like this?

What to do about the yellowing and curling of the leaves at the head of good luck (causes and solutions)

1. The temperature is too high or too low

Hongyun lives in a warm and humid environment. The suitable temperature for growth is 21-28 ℃ during the day and 18-21 ℃ at night. The highest temperature can not exceed 35 ℃. High temperature is disadvantageous to the growth of Hongyundang, but in the environment of 10 ℃ for a long time, it is also easy to cause plant growth retardation, leaf or bract turning red, white discoloration and so on. At this time, antifreeze and cold protection agents should be sprayed to prevent the plant from dying as the temperature continues to drop.

2. Overwatering or insufficient watering

Although Hongyun likes the moist environment, it can keep the basin soil moist on weekdays, and it is generally not watered on rainy days. It is best to use dried water for family care rather than directly watering it with tap water. Hongyun is a flower that can enjoy both flowers and leaves. It is best to spray water on the leaves once a day to remove dust and make the leaves bright. at the same time, it is also conducive to photosynthesis and promote the healthy growth of plants.

If watered too much, the basin soil will be too wet for a long time, which will cause lack of oxygen in the soil and eventually lead to rotting roots. Because it hinders the normal respiration and the absorption of water and nutrients, it will cause the leaves to turn yellow and fall off. After the injury, the young leaves become light yellow, and then the old leaves gradually turn yellow. in this case, watering should be controlled immediately, fertilization should be suspended, and the soil should be often loosened to make the soil well ventilated.

3. Improper prevention and control of diseases and insect pests

Good luck in the temperature or humidity is too high, poor ventilation in the environment, prone to disease and insect damage, at this time, the leaves are also prone to yellowing or curling signs. However, if the concentration of pesticides is too high in the prevention and control of diseases and insect pests, or it is polluted by toxic gases in the atmosphere, or cold water is suddenly irrigated when the temperature is high, it is easy to cause the leaf tip or leaf surface to turn yellow and scorch, or even the whole plant to die. Therefore, we should pay attention to the rational use of pesticides and try to eliminate air pollution sources.

What if the good luck is rotten?

1. Watering problem

Reason: this plant likes a slightly humid environment, but that doesn't mean the more water, the better. If the root of the plant is soaked in the soil with very high moisture for a long time, it is likely to cause root rot, and then on the outside, the leaves turn yellow or fall. In the long run, the whole plant may die.

Solution: if this is the case, we need to adjust the watering. Generally speaking, in the peak season of its growth, watering it once a week is enough. In addition, water can not be poured directly on the soil, but should be drenched from the top down, allowing the water to slowly go deep into the soil. Of course, the amount of water at a single time should not be too much.

2. Fertilization

Reason: rotten roots may also be caused by topdressing, which is too thick.

Solution: when we are topdressing, we need to adjust according to the temperature. If the temperature is high, it is not suitable to proceed.

How often is it watered in the face of good luck?

Watering does not need to be very frequent, although it likes to be wet, but we must pay attention to it. Generally speaking, we should water it in the morning, not in the middle of the night, especially in winter. Usually, we should water it once a week, because this is tantamount to waiting until all the water is dry.

We need to do it every day in summer to make the air less boring and to prevent leaves and branches from withering. Because the temperature is relatively high and muggy at this time, it is easy to scorch at this time. You can't water too much in winter, usually with an interval of ten or fifteen days.

The watering method of good luck

We pay attention to the part of watering, generally speaking, it is correct to pour it into the leaf cup. Because it likes to be wet, so we need to keep enough moisture in it. In addition, the soil needs to be kept moist.

When watering, we can not use tap water, if only tap water, then it will be used in the sun for a few days, watering should start from the top. When it is dormant in winter, it needs to control moisture and can be changed to sprinkle water on its leaves.

When watering, we should also note that we can't just pour it into the basin, it should be taken in the order from top to bottom, so that the absorption will be better, and if there is no water in the cup, its leaves will easily turn yellow.

As mentioned above, as we all know, in addition to the beautiful and generous flowers, the green and smooth leaves are also beautiful and fresh. If the leaves are yellow and curly, it will have a great impact on the appearance of the whole pot of flowers, so if the leaves turn yellow, we should find out the reason in time and solve it immediately.

What are the reasons for the yellowing of leaves at the head of good luck? What if the leaves turn yellow when good luck turns?

Hongyudou is a common herb, it is a kind of evergreen plant all the year round. Deeply loved by many flower friends. Many flower lovers have also had the experience of great luck in breeding. So, do you know the reason for the yellowing of leaves in the process of breeding? Today, the editor will introduce it to you in detail.

1. The temperature is too high or too low

Hongyun prefers the warm and humid environment. The suitable growth temperature is 21-28 ℃ during the day and 18-21 ℃ at night. The highest temperature can not exceed 35 ℃. High temperature is disadvantageous to growth, but long-term exposure to 10 ℃ can also cause plant growth retardation, redness of leaves or bracts, discoloration of whitening and so on. It should be sprayed with "New High Lipid membrane" floating liquid and other anti-freezing and anti-cold agents, in case the temperature continues to drop and cause plant death.

2. Overwatering or insufficient watering

Hongyun likes the wet environment at first, just keep the basin soil moist on weekdays, and generally do not water it on rainy days. When family farming, it is best to use dried water, not directly irrigated with tap water. Pineapple is a flower that can enjoy both flowers and leaves. It is best to spray water on the leaves once a day to remove dust and make the leaves bright. At the same time, it is also conducive to photosynthesis and promote the healthy growth of plants. Watering too much, the basin soil is too wet for a long time, resulting in lack of oxygen in the soil, causing part of the 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.

3. Improper fertilization

The flowering period of Hongyun is in winter, and sufficient fertilizer is required during flowering. Thin organic liquid fertilizers such as bean cake and sesame sauce dregs are usually applied every two weeks (with a suitable concentration of 20%). Soya bean soaking solution or fermented rice washing water can also be used. When fertilization is insufficient, there will be a lack of nitrogen and other nutrients in the basin, resulting in thin branches and leaves, thin and yellow leaves. It is necessary to pour the pot in time and gradually apply rarefied mature liquid fertilizer or compound flower fertilizer into new loose and fertile culture soil. If the fertilizer is too much, the new leaves will be thick and uneven, and the old leaves will fall off. At this time, we should immediately stop fertilization, increase the amount of water, make fertilizer flow out of the drainage hole at the bottom of the basin, or immediately pour the basin, rinse the mound with water and then plant it again into the basin.

4. The illumination is not up to standard

To make the leaves bright and blossom regularly, light is very important. In winter, there should be at least 4 to 5 hours of direct sunlight every day. In case of cloudy and rainy days, lights can be used to increase the light. In summer, the seedling pot should be placed in the shade, and indoor cultivation can also be set up as a shade net.

5. Soil quality

Good luck is suitable for the growth of loose, fertile and humus soil. In family cultivation, peat soil can be mixed with 2 parts of peat soil and 1 part of fine sand to prepare culture soil. Generally, the soil bought from the flower market is suitable for plant growth. When you add soil to it later, you should pay attention to the soil quality.

6. Improper prevention and control of diseases and insect pests

Good luck in the temperature or humidity is too high, poor ventilation in the environment, prone to disease and insect damage, at this time, the leaves are also prone to yellowing or curling signs. However, if the concentration of pesticides is too high in the prevention and control of diseases and insect pests, or it is polluted by toxic gases in the atmosphere, or cold water is suddenly irrigated when the temperature is high, it is easy to cause the leaf tip or leaf surface to turn yellow and scorch, or even the whole plant to die. Therefore, we should pay attention to the rational use of pesticides and try to eliminate air pollution sources.

7. The position is not suitable.

The head flower of Hongyun tries to avoid putting it next to the air conditioner or the TV set. Excessive radiation may also cause pathological changes in its leaves.
