Fugui Zhu is about to get sick, and the leaves are a little spotted, how should he save it?

Then you need to remove these diseased leaves, and give the bamboo enough water to contain fertilizer.

You can cut off the yellow leaves, in fact, there will be rotten roots at this time, and you have to cut off all the rotten roots. You can change the water every 3 5 days, so that the bamboo will grow greener and greener.

The cause of this phenomenon is most likely an infection with pathogenic bacteria. The disease is usually transmitted through the wound and can be exacerbated in humid conditions. In Guangdong, the frequency of the disease is highest from May to September, because the climate temperature is relatively high during this time, and the humidity in the air is also very high, and in the summer, typhoons and showers hit the wounds, and then let the disease spread quickly.

The disease begins with brown spots and causes the edges of the leaves to be yellow. After infection, its markings will be nearly round, the middle of the leaf will appear gray, and the edge of the leaf will be black-brown. If the environment is too humid, the lesions on its leaves will also grow black particles.

1.If you have several bamboos and their leaves are relatively luxuriant, it is best to breed them separately and not too densely. Place them in a well-ventilated area with bright scattered light.

2.In the early stage of the disease, you can choose to use 3000 times of gram bacteria powder containing 42 percent, or 1000 times of hydroxymycin containing 88 percent, or 800 times of copper ammonia containing 25 percent. Spray these potions on the diseased leaves two or three times a week.

3.If it is already severe, then cut off the leaves that have been contaminated with the germ.

"Chinese bamboo culture, up and down 5,000 years, clothing, food, housing and transportation, everywhere bamboo connected", bamboo has become a fashion and a trend at present. Looking at its verdant and upright, light posture, and standing proudly in the wind and snow, it gives people the impression of a "gentleman" who is indomitable and graceful. Fugui bamboo, because of its meaning of "flowers bloom rich, bamboo report peace", 365 days a year verdant green, maintenance is very simple and attract people's attention, every family will plant a pot, pray for good wishes.

But in the process of maintenance, many novices have encountered such a problem, the newly bought rich bamboo is green and lush, put it in the water for a short time, the branches and leaves appear yellow, withered, and some even appear black spots, the roots are infected and blackened, I don't know what's going on? Let's share with you where the problem is and how to deal with it, only 3 ways to solve the problem.

Symptoms <>

Gray-brown lesions appear at the tips or margins of the leaves, the lesions are irregular or semicircular, **gray-white, the edges are dark brown, with yellow halos on the outside, and small black spots scattered on them; The leaves at the base of the seedling stem are yellowed, and the inside of the stem turns red; After picking bamboo, the head becomes soft and rotten, and the foot buds are not pumped or the buds are uneven.

Causes.

Because the newly purchased Fugui bamboo does not have long roots, the plant nutrients are not enough, and yellow leaves will occur. The leaf spot fungus is mainly infected by wounds, and the disease is serious under humid conditions, and the yellow leaves will dry up when exposed to intense direct sunlight. If you don't see light in the shade for a long time, the new leaves will be tender and yellow, and the leaves will be dull.

Measures to address.

1. Choose carefully, choose fresh bamboo that is robust and well-organized, does not carry germs, and has not been rained.

2. The incision should be disinfected in time, and the incision under the seedlings can be soaked for 24 hours with 3000 times of 42% gram bacteria powder or 1000 times of 88% hydrated sulfin.

3. Prevent the plant from being too dense, accept sunlight in a timely manner, keep ventilation, and add nutrients to promote rooting. Rusty iron nails that are not usually used at home or ferrous sulfate purchased in florists can increase iron, promote the growth of Fugui bamboo, and prevent the above diseases.

It can be controlled by watering, turning the soil, spraying insect repellent, spraying pesticides, spraying nutrient solution and fertilizing.

Be sure to spray pesticides in time, but also to properly strengthen ventilation, do not plant too dense, to ensure that the sun is sufficient.

Through the correct management methods, as well as regular fertilization and watering, to understand the prevention and control methods of diseases, pay attention to the prevention and control skills.

Abundant bamboo leaves are not yellow, but covered with small spots, which is how experienced people are treated, and the most common problem with abundant bamboo is that the leaves turn yellow, because the lack of water or light can cause problems with the leaf area. Therefore, some friends always think that rich bamboo is easy to raise, which is actually wrong.

Rich bamboo is just more tenacious in survivability, but the rich bamboo leaves you raise are not good, so you can't say that you take good care of it. Therefore, no matter what kind of plants you raise, you should have a snack. Fuzhu is not a kind of bamboo, which is also a mistake that many people are prone to make, and the two families are different.

However, in appearance, Fugui bamboo is indeed very similar to that bamboo, with very convex joints, but the size of the leaves is larger than that of bamboo leaves, and they are not as graceful and clear as bamboo leaves.

Some friends, their rich bamboo does not have yellow leaves, but has yellow spots. But in fact, the existence of yellow dots shows that if you don't deal with it, it will still be yellow after a while. What is the macula?

Some friends speculate that it is not enough fertilizer or watering, but in fact, it is more likely that they are suffering from some kind of disease. If your plant has problems in the middle of the year, late summer, or early fall, it is likely to be infected by pathogens because the air is very humid and the bacteria have the right conditions to survive and cause damage to the plant.

At this time, do not use the remedy of yellow leaves - watering to solve the problem, because the air is too humid to cause the problem, and no further watering will not aggravate the condition. At this time, it is necessary to control the amount of watering, and to bring home the abundant bamboo on rainy days, even if it is not lifted outdoors, try to stay away from the window. Such lesions are not only yellow, but may also be brown, so as soon as there are spots with yellow-brown color, it may be the problem mentioned above, and on closer inspection of the leaves, we will find that the edges of the leaves are not particularly correct in color.

At this time, first of all, it is necessary to have sufficient astigmatism every day, not directly emitting light, and secondly, in order to prevent and control diseases, dilute it with bacterial liquid and spray it on the leaves with yellow spots, and be careful not to pour it into the soil.

Appropriate amount of renovated soil, sufficient water, fertilizer must be sufficient, temperature should be appropriate, spraying drugs, insect repellent sterilization and disinfection.

To ventilate the rich bamboo more, bask in more sunlight, usually you can water a little less, apply some fertilizer appropriately, and usually take more scissors to prune.

This problem can be solved by spraying pesticides, spraying insecticides, turning the soil, spraying nutrient solution and watering

Summary. Dear Hello Your question is: what happens to the yellow spots on the leaves of Fugui bamboo as follows:

First, the newly bought Fugui bamboo leaves are yellow, mainly because the Fugui bamboo has not yet grown roots, there are no roots, of course the nutrition can not keep up, it must be yellow, and the nutrient solution is also in vain. Countermeasures: Wait patiently for about 1 month, touch the pole, as long as the pole is still hard, as long as the yellow leaves are cut off, soaked in a clear glass bottle, and the leaves will grow soon.

Second, the breeding season is not right. Countermeasures: The most suitable bottle cutting time for water cultivation is from April to September, because this period is the easiest time to take root and survive.

Fugui bamboo is more cold-resistant, the more suitable growth temperature is 20-28, can withstand 2-3 low temperatures, the temperature is too low to find a way to heat up.

Thirdly, water quality, water spoilage or tap water aquaculture will cause the leaves to turn yellow. Clever strategy: cool boiled water or pure water is the best to breed rich bamboo.

Fourth, the light is too dark, Fugui bamboo can not get enough sunlight, photosynthesis can not be carried out, chlorophyll can not be formed, resulting in yellowing of leaves. Countermeasure: Move the rich bamboo filial piety god brother to a balcony and other places with good light, but try to avoid direct sunlight.

Fifth, the light is too strong, and the Fugui bamboo is placed under strong light for a long time, and the strong light irradiation causes the leaves to turn yellow. Countermeasures: Move the rich bamboo to a place with good light such as a balcony, but try to avoid direct sunlight.

In summer, it can be transplanted indoors, and it can grow healthily in the general light.

It is a very good foliage plant and is also very popular. If we raise a plant, then the main thing we care about is its leaves, including the shape and color of the leaves. Therefore, if the color of the leaf becomes black, which affects its ornamentation, then it will definitely bother us.

So, what causes its leaves to turn black? What can we do to prevent this?

1. Water quality problems

1) Cause: The most likely cause of the blackened leaves is a problem with the watering. Specifically, if the water is alkaline, it may affect its absorption of nutrients, causing its leaves to appear black.

2) Solution: It is best to water the plants with water, and it is also possible to mix some aqueous solution of compound fertilizer in it.

2. Disease problems

1) Cause: There is a disease that can cause the leaves of plants to turn black, called "brown spot disease", or "black spot disease". It is caused by a fungus and is relatively common.

In general, blackening begins on the lower leaves. At the beginning of the disease, some small black-brown dots appear on the surface of the leaves. As the disease progresses, the dots join together to become a large piece and darkens in color.

This disease can occur throughout the year, and it is the most serious in summer, and the harm is relatively large.

2) Solution: First of all, we have to cut off the diseased leaves and concentrate on them. In addition, you can spray some chlorothalonil solution.

Also, when the temperature is high and the humidity is high, try not to use flower fertilizer containing N. At this time, it is best to apply hail and carefully use phosphorus and potassium fertilizer set by a source of socks.

3. Watering problems

1) Cause: If you overwater, it can also cause this phenomenon. The roots will be the first to suffer and become rotten. Then, it will manifest itself in the leaf area, which may turn black.

2) Solution: Adjust the watering. Wait until the potting soil is dry before watering. If it is not dry, you can not water it for the time being. Also, when pouring, try not to splash on the leaves.
