How to smelt the white hair of longevity flowers? What is the reason for the white sticky stuff of l

You can use 65% zeb wettable powder, evenly spray on the plant, this disease can be transmitted, so it must be treated as soon as possible after being found, otherwise the affected area will be larger.

Like other succulent flowers, kalanchops contain more water in their bodies and are more resistant to drought, so they do not need to be watered extensively. During the growth period, as long as it is watered every 2 or 3 days, keep the potting soil slightly moist.

When the temperature is low in winter, it is necessary to control watering, if there is too much watering, the drainage is not smooth, and the potting soil is too wet, which can easily lead to root rot.

Longevity flowers. Growing white hair is infected with germs, that is, powdery mildew, which is easy to appear when raised in a poorly ventilated environment. Medications should be used immediately as soon as the disease occurs**.

Use 65% zebsen wettable powder and spray evenly on the plant. The disease can be transmitted, so it must be treated as soon as it is detected, otherwise the area of disease will be larger.

1. If it is the early stage of the disease, only one flower bud is infected, then the infected part can be removed in time.

2. If the whole pot of longevity flowers has been polluted, the situation is already very serious, there is no way to recover, you can only cut off all the buds, and then clean the plants with water, and spray them with fungicide with water after drying.

White, slightly sticky bugs growing on the kalancho flowers may be mealybugs.

It is a type of scale insect that gathers on the stems and leaves of the plant, sucks the sap in it, and hinders the normal growth of the plant. When mealybugs are found, they need to be brushed off the plant with a toothbrush dipped in water. Then prepare some drugs such as flower protector and cocoon to spray the plant for insect control.

Longevity flower maintenance method:

1. Soil requirements.

Longevity flowers have higher requirements for soil, suitable for growing in soft, well-drained soil, and should be replaced with potting soil every 1-2 years to prevent soil compaction, and can be mixed with humus, mud and fine gravel.

2. Sufficient light.

When maintaining longevity flowers, it is necessary to ensure that the light is sufficient, let the plants receive 6-8 hours of light every day, and often rotate the pots and adjust the position of receiving light, so that the longevity flowers can receive sunlight evenly and promote the uniform growth of branches and leaves.

3. Reasonable watering.

In the process of maintenance, the soil should be kept dry, and every time you water it must be watered thoroughly, in addition, when the weather is hot, you can spray water mist around the longevity flower.

4. Prune branches and leaves.

In the peak season of longevity flowers, it is necessary to pluck the tops in time, remove the dense shoots and side branches, and promote the germination of new branches of the plants, and after the longevity flowers wither, the residual flowers should be cut off, so as not to affect the flowering effect in the later stage.

Hello, that's a greasy bug. The reason is that there is no ventilation in the house. Tell you that a trick is particularly useful, mash the garlic, soak it in water and hand it over 1 or 3 times. If it is serious, use the cut garlic clove to wipe it directly, and it will be effective at one time.

Thank you for your question. Thank you so much.

1. High temperature and high humidity: The environment of high temperature and high humidity is easy to breed bacteria, and longevity flowers are easy to suffer from bacteria in such an environment. Therefore, when cultivating longevity flowers, it is necessary to choose an environment with suitable temperature and humidity so that longevity flowers can grow healthily and vigorously.

2. Stuffy and unventilated: The stuffy and unventilated environment is convenient for bacteria to multiply, creating favorable conditions for bacterial reproduction. Therefore, when cultivating longevity flowers, they need to be placed in a well-ventilated and sunny position, so that the plants are healthier.

3. Excessive nitrogen fertilizer: The main role of nitrogen fertilizer is to promote the growth of plant branches and leaves. Therefore, when cultivating longevity flowers, it is necessary to fertilize reasonably and supplement various elements at the same time.

The leaf surface of the longevity flower is yellow, peel it open to look at the roots, and then soak it, and the plant gradually recovers.

Longevity flowers in the growth process, the most likely to cause some scale insects and aphids harm, such white insects are more harmful, it is best to cut off the branches and leaves of the lesion site and destroy them intensively, after a disinfection, spray and control with the corresponding dimethoate or chlorothalonil solution, and strengthen the air circulation in the usual maintenance.

1. Scale insects

Longevity flowers like to grow in a warm and humid environment, especially in a high temperature and humidity environment, it is easy to cause the harm of scale insects, so what to do with longevity flowers and white insects, at this time the diseased branches and leaves on the plant should be cut off and destroyed in a centralized manner, the plant should be placed in a ventilated environment, reduce the number of watering, keep the potting soil slightly dry, and spray it with the corresponding chlorothalonil solution for two weeks.

2. Aphids

Aphids are also one of the common diseases of longevity flowers, in the early stage of the disease, the white larvae will slowly erode the leaves, mainly to suck the sap of the leaves, and it will cause the yellowing and wilting of the branches and leaves for a long time.

1. Strengthen ventilation

Because longevity flowers like to grow in a warm and humid environment, in the high temperature season to increase the amount of watering, but also to increase the circulation of air, can not directly put the plant in too shaded environment, after each watering to loosen the soil, can not cause water in the pot, so as not to cause some pests and diseases.

2. Trim properly

In the process of growth, the longevity flower should be properly pruned in the peak growth season, and the branches on the plant that affect the appearance should be cut off in time, and the diseased branches and leaves on the top should be cut clean, and some rotten flower branches should also be pruned, so as not to breed pathogens for a long time and affect the normal growth and development of the plant.

Longevity flowers are caused by powdery mildew, which will stop the growth of the plant, and in severe cases, the leaves may wilt and even die as a whole. ** The diseased leaves should be removed, and evenly sprayed with 65% zeb wettable powder or 15% 1000 times of powder, and the ventilated environment should be maintained during the period.

Longevity flower long white hair is actually a kind of powdery mildew, when the disease mainly invades the leaves and stems of the plant, and then there will be white powder, the disease is mild will lead to stop growing, serious will lead to leaf wilting, the whole plant wilting phenomenon.

First of all, when the occurrence of powdery mildew is relatively mild, some diseased leaves are removed in time, and then the whole plant is pruned to ensure a certain permeability and light transmittance. Finally, it is placed in a relatively ventilated environment to avoid the recurrence of the disease.

When the onset of powdery mildew is more serious, it is necessary to spray with drugs in time. For example, 65% zeb wettable powder can be used and evenly sprayed on the plant. In addition, 15% powder-rust 1000 times solution or 10% polyantimycin 1000 to 1500 times solution can also be used.

After the disease is eliminated, it is necessary to maintain and manage it, such as maintaining the optimal growth temperature of 15-25 degrees Celsius and receiving 6-7 hours of light every day. Watering in moderation, keep the potting soil slightly dry, and no stagnant water will be generated. Apply organic liquid fertilizer regularly, and do not apply thick fertilizer and raw fertilizer.
