The succulent on the balcony will have black rot every summer, how to prevent it?

Dispose of the rotten root parts in time, be sure to deal with it cleanly, otherwise a little black rot will continue to rot the whole succulent, put the treated plants in the sun for half an hour, apply carbendazim, put it in a ventilated place to dry overnight, and then pot, a small amount of watering, pay attention to shading.

Cut off all the black rot parts, and then soak the healthy part with carbendazim, it is best to dig a little more to prevent the black rot part from being dug up quickly, take it out to dry and replant it after soaking, and you can survive. Pay attention to the sun and do not leave it in the sun all the time.

First of all, we need to kill the succulents ourselves, and then change the nutrient solution, so that we can effectively prevent them.

Be sure to strengthen ventilation. Especially for indoor farming, the windows must be opened every day, and the succulents cannot be grown in a very hot state. In addition, when the room temperature is high, you should also pay attention to lowering the temperature.

It should be watered in small amounts, as too much water will increase the chance of being infected by black rot. After watering it, also be careful not to accept too much light.

First, it is hot in summer, and it is best to bring the succulent back indoors. Intense ultraviolet rays, scorching heat, are very unfriendly to succulents. It is more comfortable indoors, which can effectively avoid death and injury.

Second, regular sterilization and insect extermination, when the insect bites the flesh, the germs will enter from the wound and directly invade the flesh until it rots. Therefore, it is very important to prevent bacteria and insects. We don't wait for the outbreak of germs and pests to deal with it, because it will only be very passive, and the degree of destruction of the flesh may also increase.

Therefore, regular watering with fungicides and insecticides can prevent the occurrence of black rot.

Usually pay attention to the succulent environment, do not let direct sunlight, but also water more, because the summer season is relatively dry, and succulents are also prone to lack of water.

Watering less (reducing the amount of water in the plant) Whether the succulent leaves are wrinkled and wrinkled, you can water; No wrinkles, watering is not recommended.

To ventilate (purpose: dehumidification + enhance plant transpiration) ventilation can prevent plantation water, which is often an important cause of black rot.

Spray carbendazim (bactericidal pesticide).

The meat at home should be kept in the refrigerator as much as possible in the summer, and it can also be kept in the freezer so that it will not spoil.

This is most likely due to excessive light exposure to the flesh or insect erosion, in which case we have to cut off the black rot and then prescribe the right medicine.

When breeding succulents, the maintenance environment should ensure adequate ventilation, and if it is raised indoors, it is necessary to open more doors and windows. When the plant grows in a hot and sultry environment, black rot will occur. It is usually best to put it by the window, balcony, etc.

During the maintenance period, be sure not to get caught in heavy rain, and be sure to shelter from the rain when it rains. Because after the plant is exposed to the rain, it is difficult for the rain to discharge the water in time, and the phenomenon of black rot will appear after a long time. Or after the rain, pour out the water in the pot in time, and don't let the pot have stagnant water.

This is also very important, if it is attacked by germs, it will cause the plant to grow poorly, and it will rot. Therefore, it is necessary to do a good job of sterilization and dismantle the congratulatory to avoid the plant being infringed. The best way to do this is to spray the bactericidal drug appropriately during the curing period.

The temperature of the maintenance environment is too high, and it is easy to rot black, and the highest temperature should not be higher than 25, which is likely to suffer from the invasion of pests and diseases. During the breeding period, when the room temperature is high, it is necessary to take cooling work as soon as possible to avoid growing in a high temperature environment.

**。The first thing to do after discovering that the flesh has black rot is to cut off the diseased part and then sterilize it with a fungicide. Also remember to change it to new potting soil, before repotting, you need to soak the roots of the plant with carbendazim before planting.

In order to avoid recurrence of the disease, you can breed a pot first, so that you don't have to worry about dying.

How to prevent it. Ventilation: Summer is the season when germs are most likely to infestation, so be sure to strengthen ventilation. Especially for friends who raise flowers indoors, they must open the windows every day and not let the succulent grow in a very stuffy state. Also, when the room temperature is high, pay attention to cooling.

Control moisture: As the temperature rises, the moisture in the potting soil will also become very hot, and the potting soil should be watered in moderation, if it is watered too much, it will also increase the chance of black rot infection. After watering, also be careful not to receive too much light.

Summer is the high incidence period of succulent black rot, and meat lovers have been troubled, why there is black rot, and I hope to understand the cause of black rot. Succulent black rot is caused by the fungus "Fusarium oxysporum", the pathogen is Fusarium oxysporum, which belongs to the subphylum Semi-Knowitives, which specifically causes vascular diseases of ornamental plants, and the main symptoms are root rot, stem rot, stem base rot, flower rot, etc. How to prevent black rot and **?

Let's see what good advice Uncle Gardener has?

1. If you find that the leaves of succulents suddenly turn yellow and turn into water, you should carefully check whether it is black rot when you return to the mold, and pull up the roots of the succulents.

2. Dispose of the rotten root parts in time, be sure to deal with it cleanly, otherwise, a little black rot will continue to rot the whole succulent, put the treated plants in the sun for half an hour, apply carbendazim, and put it in a place where the wind is blowing overnight, and then pot, water a small amount of water, and pay attention to shading.

3. The main reason for black rot is that the plant has a wound, and the wound is caused by infection, how to prevent black rot: do not remove the leaves of the plant in summer, causing wounds to the plant; The disinfection of insecticidal and insect-repellent materials must be completed in the spring, otherwise it is difficult to control the insects in the summer.

4. On rainy days, I am not afraid of rain, but I am afraid that the material is impermeable, the quagmire is too much, the water storage time is too long, and it is easy to be invaded by fungi.

5. For the purchased succulents, the buyer must wash the roots with carbendazim and put it in a ventilated shade to dry for a day before it can be potted.

The 3 causes of succulent black rot are overwatering, poor soil condition, and suffering from pests and diseases. If it is caused by overwatering, the succulent plant will not be able to absorb all the water in the soil, resulting in water accumulation in the bottom soil and root rot. If the soil is in poor condition, the root system of the plant will grow in a disorderly way.

If it is exposed to pests and diseases, it will also cause the phenomenon of black rot.

1. Overwatering.

Overwatering is one of the causes of succulent black rot, due to the strong drought tolerance of succulents, people like to wait until the soil is completely dry before watering, each time follow the principle of watering to water thoroughly, resulting in a lot of watering, but the succulents can not absorb enough water, the roots of the plant will be soaked in water, blocking the stomata of the roots, affecting the normal growth of the plant.

2. The soil condition is poor.

When the soil permeability and drainage are poor, it is easy to cause excessive water accumulation at the bottom of the soil, causing the occurrence of root rot, which will also lead to the increase of soil viscosity, the decrease of porosity, and the growth space of the plant root system will also be reduced, resulting in the root system disorderly and winding growth.

3. Suffering from pests and diseases.

Succulents can also be plagued by pests and diseases, which can also lead to the occurrence of black rot. When scale insects grow on succulents, they will eat the leaves of the plants and absorb the nutrients in the plants, resulting in severe malnutrition in the growth of the plants, and it is also easy to infect the bacteria in the air, resulting in the occurrence of black rot.

4. Genetics.

The genes carried by succulents themselves are also responsible for the phenomenon of black rot. Since most succulents belong to varieties that are prone to black rot, they carry genes that are easy to black rot and are not resistant to black rot, and the probability of being infected with black rot during the growth process is high.

Succulent black rot is due to the rot of the roots caused by stagnant water, and it should be watered thoroughly. The suitable temperature for succulent growth is between 20 and 25, and the temperature is too high and too low, which is not conducive to the growth of succulents. Succulents are susceptible to root mealybugs and need to be sprayed with dimethoate solution in time.

Succulent damaged leaves need to be removed in time to reduce excess nutrient consumption.

Succulents are not tolerant to waterlogging, and improper watering can cause root rot and leaves to black rot and rot. When maintaining succulents, water thoroughly each time, and wait until the soil surface becomes dry before watering to ensure that the soil is dry and wet. In the rainy season, there is more rain, so do a good job of soil drainage.

The suitable temperature for the growth of succulents is between 20 and 25, and the temperature is suitable to promote the continuous growth of succulents. In summer, when temperatures rise and the environment is dry, it is necessary to sprinkle water in the air and on the surface of the leaves. In winter, when the temperature drops, the succulents need to be moved indoors for maintenance to avoid frostbite caused by low temperatures.

Succulents are susceptible to root mealybugs during the growth process, which will quickly erode the leaves and absorb the sap of the leaves, resulting in the growth of a large number of bacteria. When planting succulents, it is necessary to soak the soil with carbendazim solution and sterilize and disinfect before use. Root mealybugs need to be sprayed with dimethoate solution in time for control.

In the process of succulent metabolism, it is normal for the leaves to turn black and fall. When maintaining succulents, it is necessary to remove the aging and withered leaves in time, which can reduce excess nutrient consumption. Pruning in time can effectively enhance air circulation and avoid the breeding of bacteria and insect pests.
