How do potted orchids prevent root rot? How to maintain the newly planted orchid when the roots are

If you are raising potted orchids, you should water them regularly every day, not too much water, and put them in a relatively dry environment, not in a humid environment. And if you give nutrient soil, you shouldn't give too much.

We can't water too much or too often. This can avoid root rot in orchids, and it also needs to be timely when encountering insect infestations.

First of all, pay attention not to have too much light, it itself does not like sunlight, too much light will burn the rhizome. Second, pay attention to watering, not too often, standing water will harm the roots of the plant. Third, spray drugs regularly to prevent pests and diseases, and remove rotten roots in time to prevent the spread of diseases.

Newly planted orchids have rotten roots, which is soft rot. Orchids with soft rot will gradually rot from the central leaves, and then gradually spread to the false bulb, once the false bulb rots, the orchid seedlings are more difficult to survive. Because it will gradually spread to the root system, and even infect other orchid seedlings, it is difficult to treat at this step.

Soft rot of orchids occurs in a high-temperature and high-heat environment, in an unventilated environment. Usually pay attention to the prevention of soft rot, it occurs quickly. If it is found that the disease is already more serious, you can only give up the infected seedlings to protect other orchid seedlings.

Because of the speed at which it spreads as well as the speed at which it is infected, it may continue to deteriorate if not protected in time. If the root rot of the orchid is not serious, it should be treated in time.

Clause. 1. Remove the soil.

Remove all the original soil, take out the root system, and find the place where the rotten roots are repaired. Do not keep any rotten roots to reduce the occurrence of pathogens, and then soak the bactericidal drugs to prevent the continued infection of germs. You can use carbendazim or mancozeb, these bactericidal drugs can be soaked for about 20 minutes, which can have a bactericidal effect.

Then leave it in a cool, ventilated place to dry for 20 minutes, and then plant in fresh, loose and breathable soil.

The planting soil can be planted with fermented bark, peanut shells and other soft planting materials, plus some granular planting materials, such as volcanic rock, red brick particles to increase the soil voids, increase the permeability of the soil, you can also use newly bought orchid planting soil. However, many friends have their own soil allocation methods for raising orchids, which is also a matter of opinion.

Clause. Second, slow seedlings.

After planting the orchid, put it in a cool and ventilated place, ventilation is also very important, and you must not ignore it. To keep the soil warm, you can often spray the foliar surface to keep it warm. When watering, avoid the problem of water accumulation in the heart of the leaf, and find that the water must be dried in time, most of the problems of rotten roots and rotten hearts are due to the problem of water in the heart of the leaf is not dried in time, and the temperature is too high to cause bacterial infection.

Clause. 3. Insect control.

Usually pay attention to prevent small insects, you can sprinkle some small white medicine in the flower pot with balance wheels. Prevent the occurrence of various pests and diseases, reduce the occurrence of orchid wounds, and do not give germs a chance.

Soft rot mainly occurs in new seedlings, so newly planted seedlings are prone to this problem. Because the seedlings grow very fast and fragile, they have poor resistance to the environment. In a weak environment, it is more susceptible to pests and diseases.

As long as the orchid plant is raised strong, it can increase the resistance of the plant and is not easy to produce any soft rot. If you have soft rot, you must treat it in time to prevent it from spreading to other orchid plants.

After the orchids are planted, they should be placed on a shady slope to ensure ventilation. In addition, remember to bask in the sun, usually take it out early in the morning to dry. Orchids usually do not need to be exposed to strong light in the process of growth, as long as they receive some scattered light, and to ensure the humidity of the environment in which the orchid grows, if the location is too dark or dry, the plant will grow poorly, and it is usually necessary to water.

However, when watering, you should not water too much, otherwise it will accumulate water, resulting in flooding of the roots, which will also affect the breathing of the roots. Usually apply fertilizer about once every two or three weeks, preferably in the evening.

Remove the bad soil, replace it with new soil, dispose of the rotten roots, prune it clean, you can move the seedlings first, and put them in a relatively still place.

Orchids can be transplanted, replaced with a pot with fresh soil, and then watered and fertilized regularly, so that they can be better maintained.

Remove the soil, expose the root system, and cut off the rotten roots.

After the orchid rots its roots, it can be removed from the old pot and pruned properly. After pruning, the roots of the orchid can be soaked in carbendazim solution for disinfection and sterilization. After soaking, the orchid can be transplanted in loose and breathable soil, and an appropriate amount of rooting powder can be added to the soil, which can promote the root of orchid flowers, and reasonable maintenance is required in the later stage.

During the growth period of orchids, if the root system is rotten due to improper maintenance, the root system needs to be pruned. When the temperature is right and the weather is clear, remove the orchids from the old pots. After the orchid is depotted, the soil at the roots needs to be removed and cleaned, and after washing, proper pruning can be carried out to cut off both rotten and worn-root roots.

After cutting off the rotten roots, the roots of the orchid can be soaked in carbendazim solution for 10 to 20 minutes. After soaking, it can be taken out and placed in a cool and ventilated place to dry, and can be replanted later. During the curing period, you can choose a loose, fertile, breathable and well-drained nutrient soil, and disinfect the soil and new pots in advance.

After disinfecting the pots, you can put the soil in the pots, pour in the appropriate amount of rooting powder, and stir it well. Once the soil is loaded, the dried orchids can be transplanted into new potting soil. After transplanting, the orchid needs to be watered in an appropriate amount, which is conducive to the root system to adapt to the new soil, and the orchid can be placed in a cool and ventilated position for maintenance after watering.

During the maintenance period, it should be noted that the root system of the orchid has not yet adapted to the new soil, and the amount of watering needs to be controlled. During the curing period, the soil needs to be kept moist and protected from direct sunlight. After the orchid adapts to the new soil and grows new roots, it can be given sufficient light, appropriate water and fertilizer to promote the growth of the orchid.
