What to do if an orchid root rots? What to do if the orchid root is rotten

First of all, the rotten part needs to be removed, leaving about 3-5cm of root core, soaked in potassium permanganate solution for about 15 minutes before drying. Prepare suitable pots and planting materials such as soft river sand or moss, and soak them in boiling water to disinfect them. Then the dried orchids are planted in pots filled with river sand, covered and compacted with planting materials, and a layer of moss is spread on the surface to moisturize.

After planting, do not water, just put the plant in a cool place and let it regrow.

Remove all the outer skin of the rotten roots of the orchid, leaving a core about 3-5cm in length. Cut the leaves in half, soak the plants with potassium permanganate solution for about 15 minutes, and then leave them in a cool and ventilated place to dry for about half a day. If there is sun, you can roll the leaves with newspaper, expose the reeds, and place them on a shelf.

It takes about 10 minutes in summer and 1 hour in winter.

It is very difficult for the root to rot, usually to do it to prevent, you can try thousands of seasons of "Fu Meng", the effect is particularly good, don't be afraid of the disease, directly irrigate the roots with water, and it can be cured by irrigating it several times in a row.

If the root is rotten, you can use the "Fumeng" of thousands of seasons, which is a special medicine to prevent root rot, and there is no peculiar smell when used, and there is no harm to people and pets.

The first is to change the pot as soon as possible. It is found that the orchid rotten roots, it is necessary to change the soil on the pot planting material, the planting material should pay attention to the quality and water absorption performance, to fire soil or dry soil, charcoal and other planting materials as well, but also in the root reed part of the appropriate cover of some coarse sand, the effect is better.

Potassium permanganate soaking first removes the rotten part of the orchid, leaving a core of about 3-5cm, and soaks it in potassium permanganate solution for about 15 minutes before drying. Prepare suitable flower pots, soft river sand, moss and other planting materials, scald with boiling water and then disinfect.

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.

Rinse the roots of the orchid with clean water, cut off the rotten roots, soak and disinfect with diluted potassium permanganese potassium, repeat the steps twice, thoroughly disinfect, and avoid the rotten roots.

Top dressing outside the roots. Fertilization in this method is mainly to make up for the lack of nutrients in the soil, so as to solve the problem of lack of fertilizer and hail in the plant, so that the seedlings grow fast and the flowers and fruits grow hypertrophied.

1. Prune the root system: Use sterilized sharp scissors to cut off the rotten roots of the orchid, then put it in a cool place, wait for the wound to heal and then replant. 2. Dividing propagation:

If the root system of the orchid is severely rotten, it is necessary to select healthy young plants for transplanting. 3. Causes of root rotten: Orchid root rot may be caused by excessive fertilization and suffering from pests and diseases.

1. Prune the root system

When the root rot of the orchid is relatively mild, only part of the root system is rotten, while the other root systems are relatively healthy. You only need to cut off the rotten roots, place them in a ventilated and cool place after disinfection, and wait until the wound heals before replanting.

2. Dividing propagation:

If the root rot of the orchid is more serious and has not been saved, it can be re-propagated at this time, for example, it can be propagated by dividing the plant, selecting some plants with relatively healthy growth, and planting them in the potting soil, so that the orchid potted plant will grow again soon.

3. The root cause of rot

Orchids have fleshy roots, especially when there are wounds in the roots, and the application of high concentrations of fertilizers leads to fertilizer damage, which eventually leads to root rot. Therefore, when fertilizing, it is necessary to apply thin fertilizer frequently, and when using fermented organic fertilizer or long-acting fertilizer, do not get too close to the roots to avoid rotten roots.

When orchids are threatened by pests and diseases, they will cause root rot, so it is necessary to use drugs to kill pests and diseases in time to allow the roots to grow healthily. At the same time, maintain a ventilated environment, watering to be moist but not wet, dry but not dry, and give certain light conditions every day to promote root absorption and growth.

Summary. Empty roots are easier to treat, and new roots will sprout quickly after replanting; If the planting material is the reason, the planting material preparation method should be replaced; The discovery of fertilizer damage can be treated early, and it is basically abandoned if it is found too late.

Empty roots are easier to treat, and generally new roots will sprout quickly after new planting in the heavy digging belt; The reason for the planting material is to replace the preparation method of the quietly dispersed planting material; The discovery of fertilizer damage can be treated early, and it is basically abandoned if it is found too late.

All orchids with rotten roots, so the unsound and healthy root system has lost the meaning of existence, and must be cleaned in time. Otherwise, these stumps will continue to rot in the pot, affecting the growth of new root shoots. When trimming the stumps, prune all the rotten roots (including some that have been left empty).

Don't rush to plant in a pot after trimming, first put the orchid in a cool place to dry overnight, and wait for the orchid root to dry before considering planting. If there are many wounds to be trimmed, be sure to apply carbendazim (do not use the method of soaking in sterilization solution, be sure to remember).

If the orchid has rotten roots, it needs to be treated in a timely manner, if the soil quality is improper, it needs to be repotted in a timely manner, when changing the pot, it is necessary to cut off too many roots, rotten roots, and then repot, too little light is placed in the environment of scattered sunlight, too much water should be drained during rainy weather, and the potting soil can be kept dry.

The roots of the orchid have high requirements for the soil, if the orchid rots the roots, what to do is the best, the first consideration is caused by improper soil, at this time it is best to change the potting treatment, re-prepare the soil with strong porosity and rich in a lot of organic matter, when changing the pot, it is necessary to remove the previous soil on the roots, and then cut off the roots on the old roots, rotten roots, and add a small amount of charcoal or coarse sand to the bottom of the pot before entering the pot.

Light is a key factor in the flowering of orchids, if there is too little light or long-term shade environment, it will cause root rot, at this time it is best to put it in an environment with scattered sunlight, maintain 5 hours of short day treatment every day, and then put it indoors or shade it in spring and summer.

Although orchids like to grow in moist soil, but if too much watering will lead to water accumulation in the pot, resulting in root rot, it is best to control watering at this time, drainage treatment should be carried out in rainy weather, keep the potting soil dry when watering, and increase water appropriately in high temperature and dry seasons.

Fertilization of orchids must be moderate, not too much nor too little, if too much fertilizer will cause root rot, at this time it is necessary to reduce fertilization, spring and summer growth can be applied every 25 days or so to apply a phosphorus and potassium fertilizer solution, and timely watering water, so that it can be fully mixed.

Insufficient light: Different varieties of orchids require different light time, but basically all of them must be guaranteed for more than 4 hours. If there is insufficient light or dim light, the photosynthesis of the orchid plant is weak, and the potting soil is not easy to dry, and the water will stay for a long time, affecting the growth of the roots.

Unventilated or too ventilated: not ventilated, the maintenance environment is too stuffy, watering is not easy to dry, and the transpiration of the plant is also weakened; If the ventilation is too large, the water in the pot will be dried quickly, and if it is not replenished in time, the water stored in the roots will slowly run out and gradually dry out.

Lack of humidity: Orchids prefer a relatively humid environment, and the roots also need a relatively stable temperature and humidity, if it is too hot or too dry, it will cause the orchid to rot its roots.

Therefore, improve the environment and ensure the appropriate humidity, if the roots have been rotten and the growth state is not good, most of them are because the environment is too dry, especially in summer, which is caused by insufficient humidity, so we must pay attention to the control of ventilation, light and humidity.

The time and method of watering will change with the dryness and wetness of the potting soil and the temperature of the four seasons, and different watering methods can be selected to ensure that the potting soil is not too dry or too wet.

So in the summer, it is best to water at night, and by the next day the water will drip and the potting soil will not be too wet. Secondly, the growth of the plant should be observed in watering, and if the growth is not good, change the watering method and watering amount in time. In addition, if the temperature is too low (below 10) or too high (above 30), do not water, otherwise the orchid plant will rot its roots due to frostbite or steaming.

Orchids are fleshy roots, and the roots store a lot of water in them, and there is no way to absorb high concentrations of fertilizer, especially when the roots have wounds, the roots will suffer from fertilizer damage, resulting in root rot. When fertilizing, thin fertilizer should be applied frequently. In addition, when using fermented organic fertilizer or long-acting fertilizer, do not get too close to the roots to avoid root rot.

When orchid plants are threatened by pests and diseases, they will cause root rot, and in this case, everyone will often only pay attention to the prevention and control of pests and diseases, and ignore the existence of root rot. Insecticide is key, but it is also necessary to check whether the roots are rotten and depot them in time.
