The reason for the yellowing of sunflower leaves

Soil discomfort

Indoor potted sunflower should choose acidic soil, the acidity of the soil is not enough, which will affect the absorption function of the root system and cause the leaves to turn yellow.

Loose-tailed sunflower is suitable for sandy loam cultivation, if the potted soil is too sticky, it will cause part of the root system to rot at the end, then the leaves begin to yellowing, and the plant grows poorly or even dies.

Improper transplantation

Transplanting upper pot is an important step for families to plant sunflower, and improper operation will lead to yellowing of plant leaves. When potting, it is necessary to remove the outer part of the root system, but the outer root system is the main root system of root respiration. if it is damaged by improper operation, the plant nutrition supply can not be supplied, and the plant will gradually gaunt and die. And the sign of death is that the leaves turn yellow and droop.

Too much watering

Loose-tailed sunflower is higher, and the nutrients needed by leaves depend on root transport. Proper watering can quickly absorb the roots and keep the leaves green, but if the basin soil is too wet, it will affect the root respiration, affect the root water absorption, and directly cause the leaves to yellowing.

Too little watering

It is no good to water too much or too little. Sunflower needs sufficient water during its growth. When the basin soil is dry for a long time, because the growth of the plant does not get enough water, the leaves will begin to turn yellow and wither.

Humidity is too low

The growth of loose-tailed sunflower needs higher air humidity, and when the air is too dry, the leaves will slowly turn yellow. Water should be sprayed on the leaf surface and the surrounding environment 3 or 4 times a day throughout the growth period to increase air humidity. However, watering should be stopped after dormancy (after winter).

The temperature is too low

Loose-tailed sunflower likes to be warm, and it is necessary to do a good job of heat preservation and anti-freezing in winter. generally, about 10 ℃ can survive the winter safely. if the temperature is too low, the plant suffers frost injury, the leaves turn yellow and the leaf tip dries up, which leads to root damage and affects the growth of the coming year.

The light is too strong

The growth of sunflower needs plenty of sunlight, but it needs proper shade from May to September. During this period, excessive light can easily lead to plant leaf burns, which is what we often call sunburn. The leaves appear yellow spots and become scorched and yellowed. Over time, the whole plant will wilt. So in summer, the plants should be kept under shade sheds or big trees to avoid direct sunlight.

Pest infection

Leaf mites and shell insects are relatively common pests in loose-tailed sunflower. When leaf mites or shell insects grow in the leaves of loose-tailed sunflower, pests cause damage to plants, and loose-tailed sunflower will begin to turn yellow. If you do not take measures such as spraying, loose-tailed sunflower will die slowly.

The yellowing of loose-tailed sunflower leaves is a common problem in potted sunflower planting. there are many reasons for the problem, and the solutions are also different, but all we need is our careful care.

The effect of loose-tailed sunflower on household environment the cause of yellowing of loose-tailed sunflower leaves

Loose-tailed sunflower, also known as yellow coconut, is an evergreen shrub or small tree. Because of its shade tolerance and beautiful plant shape, it is often used as a garden or indoor plant in South China for ornamental purposes. Loose-tailed sunflower not only has high ornamental value, but also can purify indoor air and increase indoor moderation. Today and together to understand the role of sunflower on the home environment and the reasons for the yellowing of sunflower leaves.

The effect of Sunflower on Home Environment

After home decoration, there will be varying degrees of indoor pollution. In general, the effect of cleaning air pollution can be achieved by opening windows for ventilation and the use of green plants. Different green plants have their unique role in removing pollutants. They absorb these pollutants as nutrients and release fresh oxygen.

Sunflower is a small palm plant with strong shade tolerance. Put loose tail sunflower in the home, can effectively remove benzene, trichloroethylene, formaldehyde and other volatile harmful substances in the air. Loose-tailed sunflower, like dripping Guanyin, has the function of evaporating moisture. If you plant a loose-tailed sunflower at home, it can keep the indoor humidity at 40%-60%, especially in winter, when the indoor humidity is low, it can effectively improve indoor humidity.

Causes of yellowing of loose-tailed sunflower leaves and its solution

Loose-tailed sunflower is one of the most popular varieties of potted plants in the home, with slender leaves and beautiful plant type, but the leaves of loose-tailed sunflower sometimes turn yellow. Today, I would like to introduce to you the reasons for the yellowing of loose-tailed sunflower leaves.

Causes and solutions of yellowing of loose-tailed sunflower leaves:

1. Soil discomfort: indoor potted sunflower should choose acidic soil, the acidity of the soil is not enough, which will affect the absorption function of the root system and cause the leaves to turn yellow.

2. Improper transplant: transplanting the upper plate is a thing that needs to be done in potted sunflower planting. Dig out the plant on the pot and remove part of the peripheral root system, and the outer fine root is the main root system that plays an absorptive role. After this part of the root system is injured, it is easy to lead to problems in nutrition supply, making the plant gradually haggard and die. It is a sign that the leaves turn yellow and droop.

3. Overwatering: overwatering is also one of the reasons for the yellowing of sunflower leaves. It does not mean that if there is water in the basin soil, the plant can absorb and utilize it. When the basin soil is too wet, it affects the respiration of the plant root, thus affecting the root system's absorption of water, and causes the plant leaves to turn yellow.

4. Too little watering: too much watering is not good, neither is too little watering. Sunflower needs sufficient water during its growth period. When the basin soil is dry for a long time, because the growth of the plant does not get enough water, the leaves will begin to turn yellow and wither.

5, humidity is too low: loose-tailed sunflower likes higher air humidity, when the air is too dry, it will cause the leaves to slowly turn yellow. Water should be sprayed on the leaf surface and the surrounding environment 3 or 4 times a day throughout the growth period to increase air humidity. But stop watering after dormancy.

6, the temperature is too low: loose-tailed sunflower likes warmth, need to do a good job of heat preservation and antifreeze in winter, generally about 10 ℃ can be relatively safe to survive the winter, if the temperature is too low, the leaves will yellowing, leaf tip dry, and lead to root damage, affecting the growth of the coming year.

7. The sun is too strong: loose-tailed sunflower likes the semi-overcast environment from May to September. When the sun shines directly, there will be some phenomena such as leaf yellowing, focal tip, focal edge and so on. During this period, it should be placed under a shade or under a big tree to avoid direct sunlight.

8. Excessive fertilization: excessive fertilization will cause the reverse osmosis of plant root cells and make the plant lose water. If the degree is light, it will lead to the focal tip and edge of the leaf, and in serious cases, it will cause rotten root death.

9. Sticky weight of potted soil: loose-tailed sunflower is suitable for planting in sandy loam. If the potted soil is too sticky and heavy, it will cause part of the root system to rot at the top, then the leaves begin to turn yellow, and the plants grow poorly or even die.

10. Pest infection: leaf mites and shell insects are relatively common pests in loose-tailed sunflower. When leaf mites or shell insects grow in the leaves of loose-tailed sunflower, insect pests cause damage to plants, and loose-tailed sunflower will begin to turn yellow. If you do not take measures such as spraying, loose-tailed sunflower will die slowly.

The yellowing of loose-tailed sunflower leaves is a common problem in potted sunflower planting. there are many reasons for the problem, and the solutions are also different, but all we need is our careful care. This is the reason for the yellowing of loose-tailed sunflower leaves and its solutions. I hope it can be helpful to everyone.
