The anthurium leaves and flowers are all black, and the leaves are falling, as if the fire is burnin

One symptom is that on the leaves and flowers, watery spots can be seen on the back of the leaves and flowers in the early stage, and brown spots appear on the leaf margins in the later stage, accompanied by yellow halos. The other is when the bacterial infection begins on the stem and rapidly spreads to the entire plant through the microtubule bundles. In the early stage, it can be found that the color of the new leaves is dull, which is due to the microtubule bundle being blocked by bacteria, which hinders the flow of water and nutrients in the body, so that the leaf color is dull and the leaves are yellow, and the infection of this type will cause the peduncle and leaves to fall off from the plant in a short period of time, and the growth point will quickly decay and have a concentrated outflow of bacteria.

There is no specific drug for bacterial diseases, and the main focus is on prevention

Strengthen the control of the temperature of the greenhouse (the ideal breeding condition for bacteria is about 30 degrees Celsius), the hygienic environment, and the flow of personnel and work tools in the production area. Try not to use nitrogen fertilizer with high NH4 state in plant growth. Go to a place or isolate the diseased strain!

Leaf blight nematode disease is caused by nematode infection of the genus Slippery Blade Nematode, which mainly infects roots and leaves. The disease is characterized by the formation of necrotic spots or brown spots along the veins, the roots are swollen, and finally the whole leaf is dried up. The prevention and control methods are mainly to strengthen the quarantine of seedlings, select strong seedlings, and do a good job in the disinfection of cultivation substrates.

Take it out of the soil and wash the roots separately from the soil. Take a clean container with water and raise it, and change the water once every three days (don't use nutrient solution).

Remember to cut the blackened flowers, the withered leaves, and the rotten roots.

To tell you the truth, I feel that there is no help.

Anthurium leaves withered and wilted? Don't do that anymore, it will lead to direct death.

In general, if you want to keep the anthurium leaves alive, you can also cut off the black flowers and cut off the withered leaves. After cutting off some of the bad substances on it, the anthurium leaves can choose to regenerate, and they can also grow very luxuriantly. Don't forget to water the anthurium leaves, otherwise it will turn black and yellow.

There is a lot of fertilizer needed to breed this plant, and you have to top dressing from time to time.

Anthurium leaves are black, as long as proper maintenance, can still survive, you can change a new pot, change some new soil, to choose the right fertilizer, to ensure the depth and air permeability of the soil.

Yes, at this time, it is likely that there is a lot of watering and fertilization, and it is necessary to change the plant to a pot, and proper watering and fertilization can make it come alive.

I can live. Because the anthurium leaves are black, it does not mean that it is dead, it may be caused by lack of water, so it can still survive.

1. The first situation is that the old leaves and the new leaves, if the leaves are yellow at the same time, the main reason is because of the lack of light for a long time. Solution: Increase the lighting appropriately.

2. The second situation is that the old leaves are yellow, the main reason is that there is a long-term lack of water or watering is not watered thoroughly, which will occur. Solution: Water thoroughly every time.

3. The third situation is that if the new leaves are yellow, but the old leaves are normal, it means that the amount of watering is too large, or there is a lack of fertilizer. The solution: control watering, or top dressing.

Specific prevention measures:

First of all, cut off the yellowing leaves, put them in a cool place, and wait for the water to dry out, and then water, don't rush to fertilize. There may be two situations, one is that the air humidity is too small, that is, too dry; Another situation is the lack of trace mineral elements.

In fact, it is to control the temperature and humidity, bask in the sun in the morning and evening, and apply fertilizer appropriately.

When the anthurium leaves are yellow, dry and rotten, it may also be caused by bacteria, and the garlic juice solution, vinegar solution or carbendazim, chlorothalonil 800-1000 times liquid and other fungicides can be sprayed for prevention and control.

Indoor maintenance of anthurium should be managed in a semi-shaded, moist and warm environment, and the temperature should be between 20-25 and not higher than 33, otherwise it is easy to have uncomfortable symptoms; The air humidity must be between 75-90%, and the leaves below 50% are prone to scorched edges and dry up. You can also refer to: the solution to the yellowing and blackening of anthurium leaves.

Is it sunburned? This flower is afraid of the sun and dries. Spray some water mist on the leaves frequently to increase the humidity, and it will recover quickly.

There are many reasons why leaves turn black:

1. Big rotten roots: After taking the flowers out of the pot, you can see that the roots are very watery, and many roots are rotten and black. Cut off the rotten roots and repot them.

2. Insufficient water: The pot is very dry, and the leaves first shrank and then turn black. Hydrate and irrigate roots.

3. Fertilizer damage: There is too much fertilizer accumulation in the pot, and the root system can be seen to rot after potting, and the roots have obvious yellow, and then blacken. Wash the roots with clean water and repot.

4. Insect pests, with good root systems, are leaves shriveled and blackened, and there are dense small black spots on the back of the leaves. It is mainly caused by pests of stinging and sucking mouthparts, mainly leaf mites (red spiders), thrips, ash scales, etc. Clear the bite of the leaves, then spray insecticide, if it is an ash scale, you can first spray a certain amount of laundry detergent water, before spraying insecticide.

5. Diseases, the main diseases of anthurium are that leaf blight (leaf blight) is mainly caused by water problems.

Anthurium anthurium, formerly known as anthurium andraeanum (scientific name: anthurium andraeanum) Araceae, genus Anthurium andraeanum.

Perennial evergreen herbaceous flowers. The flowers are unique, there are Buddha flame inflorescences, the color is bright and gorgeous, the colors are rich, each flower has a long flowering period, the color of the flowers changes greatly, the inflorescence withers from the bracts to the flowers, and the color undergoes a series of changes, from the beginning of the beige to milky white, and finally becomes green, and becomes yellow before withering. Leaf-shaped bracts, common bracts are red, pink, white, etc., which have great ornamental value.

It can be propagated by sowing and dividing. The flower language of Anthurium is to show great ambition and enthusiasm.

Watering too diligently, the cultivation substrate of anthurium is generally peat, the ability to retain fertilizer and water is strong, but it is not easy to absorb water after drying, so it should be watered thoroughly when it is slightly wet, not watered after drying, the amount of fertilizer can not be too large, light fertilizer is applied frequently, too much fertilizer is applied black, wilted, and the plant dies. The maintenance environment is better in semi-shade, but Anthurium is particularly light-loving, so it is necessary to turn the growth direction frequently to keep the plant shape beautiful.

The leaves are yellow and dry, and the flowers wither for the following reasons:

1. Sunburn (in the yellow part of Figure 1).

2. Disease (brown part of Rongtu).

3. Lack of fertilizer (yellow leaves).

4. Lack of water (old flowers wither into a tendency to burn yellow).

Countermeasures: 1. Do not get direct sunlight. Indoor maintenance is best.

2. This disease is not contagious. Non-proliferation. But it affects the aesthetics. Wait for the new leaves to grow, and then remove them.

3. Increase the amount of fertilizer.

4.Master the correct watering method, find 1 pot of water, and put the anthurium into the basin to self-suck.

If the leaves of Anthurium are found to be yellow when cultivated at home, then most of them are caused by improper maintenance, and the reasons should be analyzed, and then targeted to improve the soil quality, stop watering, supplement light, increase temperature, etc., so that the plant can slowly recover its health.

Hello, my anthurium grows black when it grows new leaves, dies, and does not bloom, what should I do.

The leaves of Anthurium are dry and dry, and there are many of them, which are caused by four conditions. First, the strong light burns, can only accept astigmatism, when the light is too strong, you must block the scorching sun in time, and move to a ventilated, astigmatism good environment. Second, if you are infected with a disease, you need to cut off the diseased leaves as soon as possible and spray them with drugs to sterilize and disinfect.

The third is improper fertilization, high fertilizer concentration, and burns the leaves. It is necessary to rinse the fertilizer with clean water. Fourth, there is too much watering and roots.

Drain water as soon as possible and enhance ventilation.

1. There are many reasons why the tip of the anthurium leaves is scorched, if it is caused by the normal metabolism of the old leaves, the old leaves can be cut off, and the fallen old leaves can be picked up and removed in time.

2. If it is caused by strong light burning leaves, you can avoid light in summer and move to a cool place after burning.

3. If it is caused by disease, the diseased leaves can be removed, ventilation can be maintained, and pesticides can be sprayed symptomatically.

4. If the fertilization is too concentrated, the fertilization should be suspended first, and then a large amount of water should be poured to dilute it.
