The tips of the leaves of bonsai cogstalph are black and dry

The blackening of the tips of the leaves of bonsai coggylum and dry hair may be due to the following reasons:

1.Improper water management: Cochinus has a high need for water, and if the potting soil is too dry or too wet, it can cause the tips of the leaves to turn black and dry. Therefore, it is necessary to keep the potting soil moist and pay attention to the ventilation of the environment.

2.Insufficient nutrients: Cochleus bonsai needs sufficient nutrients to maintain normal growth, and if there are not enough nutrients in the soil, it will cause the tips of the leaves to turn black and dry. It is necessary to fertilize regularly and supplement the corresponding nutrients according to the growth stage and needs of Coggy.

3.Pest and disease infestation: Cochinus can be attacked by pests and diseases, such as leaf curl, which is a common disease that causes the leaves to curl, turn yellow, and dry up. Timely detection and control measures such as spraying pesticides or selecting disease-resistant varieties need to be detected and taken in a timely manner.

In view of the above reasons, corresponding measures can be taken to improve and **. At the same time, paying attention to reasonable water and nutrient management in the maintenance process and keeping the environment well ventilated will help prevent and improve the problem of black and dry hair at the tip of the leaves of Coxagulus.

The reasons are: 1. There is too little water in the bonsai of Cocoon, so it is necessary to water the pot immediately and strengthen the environmental ventilation, which can improve the blackening and dry hair.

2. If the nutrients are insufficient, it is necessary to supplement the corresponding fertilizer according to the position of the black leaves, or you can directly use compound fertilizer.

There are only several reasons for the drooping leaves of Coghu.

Excessive watering and rotting roots.

The main cause of leaf drooping is water loss, which mainly includes root rot caused by overwatering, and then leaf drooping. When watering coxagulus, there is a very important point, that is, the soil should not accumulate water. Basically, when watering the coggy, watering should be done thoroughly, but it is strictly forbidden to accumulate water, the soil is watered for a long time, too wet will lead to root rot, water can not be absorbed, it is easy to produce leaf drooping.

The rotten roots of Coxaculus can be treated, disinfected with disinfectants such as chlorothalonil, replanted with new soil, and then watered to avoid root rot again.

Soil compaction. There is another condition that can also cause water loss in coggy, which is soil compaction. Because soil compaction will reduce the ability of water to penetrate, the water will not be absorbed by the roots, which will cause the leaves to lose water and then droop.

Therefore, when choosing the soil, it is best to choose loose and breathable soil, properly loosen the soil during the breeding of Coghu, and add the microbial agent of the sea to make the roots grow normally and have good permeability and drainage ability.

See less light. When cultivating coggy, it is necessary to maintain suitable light, if the exposure to light is too little, it will make its branches and leaves grow weak, the leaves are larger, and the phenomenon of drooping. This phenomenon is mainly to prune it, cut off a section of the long branches, keep the main stem at 30cm, and then keep it with sufficient light, but avoid direct sunlight.

Summary. First of all, you should check the soil moisture of the coggywood to make sure that the soil remains moist. If the ground is too dry, you should add moisture to it and check the soil moisture frequently to make sure the soil is moist.

Secondly, good ventilation helps the growth of cochinese. If it is cultivated in a humid environment, you can put it in a ventilated environment to make it smell more. Finally, make sure that the coggylum is exposed to effective light and has enough sunlight, especially in the morning and evening, to ensure normal growth.

If it is cultivated in a humid environment, you can put it in a doudou finch environment to make it smell more. Finally, make sure that the coggylum is exposed to effective light and has enough sunlight, especially in the morning and evening, to ensure normal growth. Bright pin segment.

There's glue-like slimy on the page, what's the reason.

Sprouts that have just been sent.

foliage. The slimy sprout leaves may be caused by the bite of a bright insect in the wild. Sometimes pests will bite the buds and leaves on the leaves, leaf axils and stems, and the leaves will be sticky mixed with the pest's glue.

In order to prevent pests, the control can be strengthened in the room where the cocoon is cultivated, so that the outdoor pests are kept away from the coxagulus.

I grow it indoors.

Can sunlight shine through?

Cochines can be grown indoors. It is a drought-resistant, heat-tolerant tree that is suitable for indoor planting, and can be planted indoors in pots, which can make your living space more vibrant and welcoming. When potting plants, it should be noted that the soil should be kept moist but not stagnant; During the growing season, it should be watered irregularly, and humus or manure should be used to fertilize it.

Regularly clean the indoor tanks, bury them to remove particulates and parasites, and erect sap to prevent them from invading the trees. In addition, the nutrient soil and air should be replaced regularly to keep the air fresh and create a comfortable growing environment.

Hello dear, <>

What is the reason for the blackening of the leaf edges of the coggylum, the answer is as follows: The reasons for the blackening of the leaf edges of the coxagulus may be as follows:1

Lack of light: Cochinus needs plenty of sunlight, and if it is not lit, it may cause the edges of the leaves to turn black. Please ensure that you receive at least 6 hours of sunlight per day.

2.Lack of moisture: Cochinus prefers a moist environment, and a lack of moisture can cause the edges of the leaves to turn black.

Make sure the soil is moist but don't overwater it to avoid root rot. 3.Pests and diseases:

Cochinus can be affected by pests and diseases, which can cause the edges of the leaves to turn black. Please check the coggylum regularly, and if you find any pests and diseases, you should take measures to prevent and control them in time. 4.

Nutrient deficiencies: Cochines need adequate nutrients, and if they are undernutrient, they may cause the edges of the leaves to turn black. Please fertilize the cochcoon regularly and choose a fertilizer suitable for the growth of the coggy.

Hello, to make the leaves of the cochleus bonsai red, there are several ways:1Control Lighting:

Cochinus likes full sunlight, but too much sunlight will cause the leaves to turn yellow, so it is necessary to control the light time and intensity to allow it to grow in the right light. 2.Moisture control:

Coggywood prefers a moist environment, but overwatering can cause root rot and side fissures affecting leaf growth. Therefore, it is necessary to control the amount and frequency of watering to keep the soil at a moderate humidity. 3.

Fertilization: Cogsculin needs adequate nutrients to grow healthily, so it should be fertilized regularly. Fertilizers containing trace elements such as iron, zinc, and magnesium can be used, which can promote the reddening of leaves.

4.Control temperature: Coggylum prefers a warm environment, but excessive heat or cold can affect leaf growth.

Therefore, it is necessary to control the temperature in the room and let it grow at the right temperature for the grinding and enlightenment. In short, to make the leaves of Coxagus bonsai red, it is necessary to control factors such as light, moisture, fertilizer and temperature, so that it can grow in a suitable environment.

Fungal Fungal Fusarium However, the blight of coggy generally shows dehydration wilting, and then the yellow leaves fall off, which is consistent with the symptoms of fungal blight.

It is caused by Verticillium dahlia in the sub-sapiens of the semi-known fungus, the Filospora and the Filospora fungi, and has similarities with the blight, as a soil-borne pathogen, it mainly invades through the roots of seedlings, and can also invade through wounds, and spreads to all parts of the plant through the ducts, resulting in obstacles in the absorption and transportation of plant water and minerals, so that the host plant appears wilted and weakened, resulting in a large number of yellow leaves and defoliation of Cog. japonicus, and finally the whole plant dies. The speed and severity of the disease are closely related to the number of pathogens distributed around the root system, and soil moisture and nitrogen fertilizer excess will aggravate the infection and severity of the disease.

There are many reasons for the yellow leaves of Cochinus. It may be due to too much moisture, and it is necessary to drain the stagnant water immediately and strengthen the ventilation of the environment. It may be due to the lack of nutrients, and the corresponding fertilizer needs to be supplemented according to the position of the yellow leaves, or compound fertilizer can be used directly.

It may be due to blight, and it is necessary to spray a mixture of decorator, Wokang and Lu'an.

Cause. There are two main reasons for leaves to turn yellow, one is improper fertilization, one is improper watering, and of course there are some other factors, but these two are the most basic and important reasons for leaves to turn yellow.

Resolution. Improper fertilization:

Let's start with the reasons for improper fertilization. The dependence on fertilizers is relatively high. If the long-term fertilization is insufficient, it will cause no nutrients to be absorbed by the plant, and the leaves will turn yellow; However, if there is too much fertilizer, it can hurt its roots and cause the leaves to turn yellow.

Improper fertilization can also affect its flowering or disappearance of the finger keys. Therefore, daily fertilization must be made according to the manual of fertilizer to make a reasonable ratio. Also, don't see that there is a problem with the plant and think that it lacks nutrients and can be fertilized blindly.

Improper watering: During cultivation, if the leaves wilt, it is a sign of lack of water. At this time, they should be watered in time and placed in a semi-cool place for maintenance.

They will recover slowly, but if not watered in time, the leaves will turn yellow over time. When watering, it is necessary to control the amount of water and do not accumulate water, which will make the soil lose its air permeability, affect the health of the plant, and the leaves will turn yellow. In the summer, watering can be done once a day, at 10 p.m.

If it is dry the next morning, you can water it properly.
